This is a good place to put initialization code for your controller. + * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The + * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an + * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a + * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will + * also be called when your bindings are initialized. + * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on + * changes. Any actions that you wish to take in response to the changes that you detect must be + * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook + * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not + * be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; + * if detecting changes, you must store the previous value(s) for comparison to the current values. + * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing + * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in + * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent + * components will have their `$onDestroy()` hook called before child components. + * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link + * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. + * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since + * they are waiting for their template to load asynchronously and their own compilation and linking has been + * suspended until that occurs. + * + * #### Comparison with life-cycle hooks in the new Angular + * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are + * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular: + * + * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`. + * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor. + * In Angular you can only define hooks on the prototype of the Component class. + * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to + * `ngDoCheck` in Angular. + * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be + * propagated throughout the application. + * Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an + * error or do nothing depending upon the state of `enableProdMode()`. + * + * #### Life-cycle hook examples + * + * This example shows how you can check for mutations to a Date object even though the identity of the object + * has not changed. + * + * + * + * angular.module('do-check-module', []) + * .component('app', { + * template: + * 'Month: ' + + * 'Date: {{ $ctrl.date }}' + + * '', + * controller: function() { + * this.date = new Date(); + * this.month = this.date.getMonth(); + * this.updateDate = function() { + * this.date.setMonth(this.month); + * }; + * } + * }) + * .component('test', { + * bindings: { date: '<' }, + * template: + * '
        {{ $ctrl.log | json }}
        ', + * controller: function() { + * var previousValue; + * this.log = []; + * this.$doCheck = function() { + * var currentValue = this.date && this.date.valueOf(); + * if (previousValue !== currentValue) { + * this.log.push('doCheck: date mutated: ' + this.date); + * previousValue = currentValue; + * } + * }; + * } + * }); + *         + * + * + * + *         * + * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the + * actual identity of the component doesn't change.

If the binding expression is non-assignable, or if the attribute isn't + * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`}) + * will be thrown upon discovering changes to the local value, since it will be impossible to sync + * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`} + * method is used for tracking changes, and the equality check is based on object identity. + * However, if an object literal or an array literal is passed as the binding expression, the + * equality check is done by value (using the {@link angular.equals} function).

Often it's desirable to pass data from the isolated scope + * via an expression to the parent scope. This can be done by passing a map of local variable names + * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` + * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. + * + * In general it's possible to apply more than one directive to one element, but there might be limitations + * depending on the type of scope required by the directives. The following points will help explain these limitations. + * For simplicity only two directives are taken into account, but it is also applicable for several directives: + * + * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope + * * **child scope** + **no scope** => Both directives will share one single child scope + * * **child scope** + **child scope** => Both directives will share one single child scope + * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope.

It can be either + * `true` or an object hash with the same format as the `scope` property. + * + * When an isolate scope is used for a directive (see above), `bindToController: true` will + * allow a component to have its properties bound to the controller, rather than to scope. + * + * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller + * properties. You can access these bindings once they have been initialized by providing a controller method called + * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings + * initialized. + * + *

The controller is instantiated before the - * pre-linking phase and it is shared with other directives (see + * pre-linking phase and can be accessed by other directives (see * `require` attribute). This allows the directives to communicate with each other and augment * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: * * * `$scope` - Current scope associated with the element * * `$element` - Current element * * `$attrs` - Current attributes object for the element - * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope. - * The scope can be overridden by an optional first argument. - * `function([scope], cloneLinkingFn)`. - * + * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: + * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: + * * `scope`: (optional) override the scope. + * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. + * * `futureParentElement` (optional): + * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. + * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkingFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like ``). + * * See also the `directive.templateNamespace` property. + * * `slotName`: (optional) the name of the slot to transclude.

The - * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the - * injected argument will be an array in corresponding order.

For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. + * See the {@link $compileProvider#component} helper for an example of how this can be used. + * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is + * raised (unless no link function is specified and the required controllers are not being bound to the directive + * controller, in which case error checking is skipped). The name can be prefixed with: * * * (no prefix) - Locate the required controller on the current element.

        + * **Note:** When testing an element transclude directive you must not place the directive at the root of the + * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives + * Testing Transclusion Directives}. + *
        + * + * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the + * directive's element, the entire element or multiple parts of the element contents: + * + * * `true` - transclude the content (i.e. the child nodes) of the directive's element. + * * `'element'` - transclude the whole of the directive's element including any directives on this + * element that defined at a lower priority than this directive. When used, the `template` + * property is ignored. + * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. + * + * **Mult-slot transclusion** is declared by providing an object for the `transclude` property. + * + * This object is a map where the keys are the name of the slot to fill and the value is an element selector + * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) + * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). + * + * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives} + * + * If the element selector is prefixed with a `?` then that slot is optional. + * + * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to + * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. + * + * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements + * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call + * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and + * injectable into the directive's controller. + * + * + * #### Transclusion Functions + * + * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion + * function** to the directive's `link` function and `controller`. This transclusion function is a special + * **linking function** that will return the compiled contents linked to a new transclusion scope. + * + *
        + * If you are just using {@link ngTransclude} then you don't need to worry about this function, since + * ngTransclude will deal with it for us. + *
        + * + * If you want to manually control the insertion and removal of the transcluded content in your directive + * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery + * object that contains the compiled DOM, which is linked to the correct transclusion scope. + * + * When you call a transclusion function you can pass in a **clone attach function**. This function accepts + * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded + * content and the `scope` is the newly created transclusion scope, which the clone will be linked to. + * + *
        + * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function + * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. + *
        + * + * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone + * attach function**: + * + * ```js + * var transcludedContent, transclusionScope; + * + * $transclude(function(clone, scope) { + * element.append(clone); + * transcludedContent = clone; + * transclusionScope = scope; + * }); + * ``` + * + * Later, if you want to remove the transcluded content from your DOM then you should also destroy the + * associated transclusion scope: + * + * ```js + * transcludedContent.remove(); + * transclusionScope.$destroy(); + * ``` + * + *
        + * **Best Practice**: if you intend to add and remove transcluded content manually in your directive + * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), + * then you are also responsible for calling `$destroy` on the transclusion scope. + *
        + * + * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} + * automatically destroy their transcluded clones as necessary so you do not need to worry about this if + * you are simply using {@link ngTransclude} to inject the transclusion into your directive. + * + * + * #### Transclusion Scopes + * + * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion + * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed + * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it + * was taken. + * + * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look + * like this: + * + * ```html + *
        + *
        + *
        + *
        + *
        + *
        + * ``` + * + * The `$parent` scope hierarchy will look like this: + * + ``` + - $rootScope + - isolate + - transclusion + ``` + * + * but the scopes will inherit prototypically from different scopes to their `$parent`. + * + ``` + - $rootScope + - transclusion + - isolate + ``` + * * - * * ### Attributes * * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the * `link()` or `compile()` functions.

The payoff - * comes in the way of guarantees that promise and deferred APIs make, see - * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. - * - * Additionally the promise api allows for composition that is very hard to do with the - * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. - * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the - * section on serial or parallel joining of promises. - * - * - * # The Deferred API - * - * A new instance of deferred is constructed by calling `$q.defer()`. - * - * The purpose of the deferred object is to expose the associated Promise instance as well as APIs - * that can be used for signaling the successful or unsuccessful completion, as well as the status - * of the task. - * - * **Methods** - * - * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection - * constructed via `$q.reject`, the promise will be rejected instead. - * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to - * resolving it with a rejection constructed via `$q.reject`. - * - `notify(value)` - provides updates on the status of the promise's execution. This may be called - * multiple times before the promise is either resolved or rejected. - * - * **Properties** - * - * - promise – `{Promise}` – promise object associated with this deferred. - * - * - * # The Promise API - * - * A new promise instance is created when a deferred instance is created and can be retrieved by - * calling `deferred.promise`. - * - * The purpose of the promise object is to allow for interested parties to get access to the result - * of the deferred task when it completes. - * - * **Methods** - * - * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or - * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously - * as soon as the result is available. The callbacks are called with a single argument: the result - * or rejection reason. Additionally, the notify callback may be called zero or more times to - * provide a progress indication, before the promise is resolved or rejected. - * - * This method *returns a new promise* which is resolved or rejected via the return value of the - * `successCallback`, `errorCallback`. It also notifies via the return value of the - * `notifyCallback` method. The promise can not be resolved or rejected from the notifyCallback - * method. - * - * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` - * - * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise, - * but to do so without modifying the final value. This is useful to release resources or do some - * clean-up that needs to be done whether the promise was rejected or resolved. See the [full - * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for - * more information. - * - * Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as - * property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to - * make your code IE8 and Android 2.x compatible. + ASTInterpreter.prototype = { + compile: function(ast) { + var self = this; + findConstantAndWatchExpressions(ast, self.$filter); + var assignable; + var assign; + if ((assignable = assignableAST(ast))) { + assign = this.recurse(assignable); + } + var toWatch = getInputs(ast.body); + var inputs; + if (toWatch) { + inputs = []; + forEach(toWatch, function(watch, key) { + var input = self.recurse(watch); + input.isPure = watch.isPure; + watch.input = input; + inputs.push(input); + watch.watchId = key; + }); + } + var expressions = []; + forEach(ast.body, function(expression) { + expressions.push(self.recurse(expression.expression)); + }); + var fn = ast.body.length === 0 ?

The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * ## The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promise's execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * ## The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved + * with the value which is resolved in that promise using + * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). + * It also notifies via the return value of the `notifyCallback` method. The promise cannot be + * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback + * arguments are optional. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * ## Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * ```js + * promiseB = promiseA.then(function(result) { + * return result + 1; + * }); + * + * // promiseB will be resolved immediately after promiseA is resolved and its value + * // will be the result of promiseA incremented by 1 + * ``` + * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * ## Differences between Kris Kowal's Q and $q + * + * There are two main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in AngularJS, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * ## Testing + * + * ```js + * it('should simulate promise', inject(function($q, $rootScope) { + * var deferred = $q.defer(); + * var promise = deferred.promise; + * var resolvedValue; + * + * promise.then(function(value) { resolvedValue = value; }); + * expect(resolvedValue).toBeUndefined(); + * + * // Simulate resolving of promise + * deferred.resolve(123); + * // Note that the 'then' function does not get called synchronously. + * // This is because we want the promise API to always be async, whether or not + * // it got called synchronously or asynchronously. + * expect(resolvedValue).toBeUndefined(); + * + * // Propagate promise resolution to 'then' functions using $apply(). + * $rootScope.$apply(); + * expect(resolvedValue).toEqual(123); + * })); + * ``` + * + * @param {function(function, function)} resolver Function which is responsible for resolving or + * rejecting the newly created promise.

Its goal is to assist in writing code in a way that (a) is secure by default, and + * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * ### Overview + * + * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in + * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically + * run security checks on them (sanitizations, whitelists, depending on context), or throw when it + * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML + * can be sanitized, but template URLs cannot, for instance. + * + * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: + * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it + * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and + * render the input as-is, you will need to mark it as trusted for that context before attempting + * to bind it. + * + * As of version 1.2, AngularJS ships with SCE enabled by default. + * + * ### In practice + * + * Here's an example of a binding in a privileged context: + * + * ``` + * + *

        + * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV, which would + * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog + * articles, etc. via bindings. (HTML is just one example of a context where rendering user + * controlled input creates security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, AngularJS makes sure bindings go through that sanitization, or + * any similar validation process, unless there's a good reason to trust the given value in this + * context. That trust is formalized with a function call. This means that as a developer, you + * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, + * you just need to ensure the values you mark as trusted indeed are safe - because they were + * received from your server, sanitized by your library, etc. You can organize your codebase to + * help with this - perhaps allowing only the files in a specific directory to do this. + * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then + * becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * build the trusted versions of your values. + * + * ### How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as + * a way to enforce the required security context in your data sink. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs + * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, + * when binding without directives, AngularJS will understand the context of your bindings + * automatically. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ### Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, AngularJS only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ### This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (e.g. + * `
        `) just works. The `$sceDelegate` will + * also use the `$sanitize` service if it is available when binding untrusted values to + * `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you + * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in + * your application. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * + * ### What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered, and the {@link ngSanitize.$sanitize $sanitize} service is available (implemented by the {@link ngSanitize ngSanitize} module) this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently, no bindings require this context. Feel free to use it in your own directives. | + * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
        Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does (it's not just the URL that matters, but also what is at the end of it), and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently, no bindings require this context. Feel free to use it in your own directives. | + * + * + * Be aware that `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them + * through {@link ng.$sce#getTrusted $sce.getTrusted}. There's no CSS-, URL-, or JS-context bindings + * in AngularJS currently, so their corresponding `$sce.trustAs` functions aren't useful yet. This + * might evolve. + * + * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist}         + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ### Show me an example using SCE. + * + * + * + *

Also do note that this is an app-wide setting, so if + * you are writing a library, you will cause security bugs applications using it. + * + * That said, here's how you can completely disable SCE: + * + * ``` + * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { + * // Completely disable SCE. For demonstration purposes only! + * // Do not use in new projects or libraries. + * $sceProvider.enabled(false); + * }); + * ``` + * + */ + + function $SceProvider() { + var enabled = true; + + /** + * @ngdoc method + * @name $sceProvider#enabled + * @kind function + * + * @param {boolean=} value If provided, then enables/disables SCE application-wide. + * @return {boolean} True if SCE is enabled, false otherwise. + * + * @description + * Enables/disables SCE and returns the current value. + */ + this.enabled = function(value) { + if (arguments.length) { + enabled = !!value; + } + return enabled; + }; + + + /* Design notes on the default implementation for SCE. + * + * The API contract for the SCE delegate + * ------------------------------------- + * The SCE delegate object must provide the following 3 methods: + * + * - trustAs(contextEnum, value) + * This method is used to tell the SCE service that the provided value is OK to use in the + * contexts specified by contextEnum. It must return an object that will be accepted by + * getTrusted() for a compatible contextEnum and return this value. + * + * - valueOf(value) + * For values that were not produced by trustAs(), return them as is. For values that were + * produced by trustAs(), return the corresponding input value to trustAs. Basically, if + * trustAs is wrapping the given values into some type, this operation unwraps it when given + * such a value. + * + * - getTrusted(contextEnum, value) + * This function should return the a value that is safe to use in the context specified by + * contextEnum or throw and exception otherwise. + * + * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be + * opaque or wrapped in some holder object. That happens to be an implementation detail. For + * instance, an implementation could maintain a registry of all trusted objects by context. In + * such a case, trustAs() would return the same object that was passed in. getTrusted() would + * return the same object passed in if it was found in the registry under a compatible context or + * throw an exception otherwise. An implementation might only wrap values some of the time based + * on some criteria. getTrusted() might return a value and not throw an exception for special + * constants or objects even if not wrapped. All such implementations fulfill this contract. + * + * + * A note on the inheritance model for SCE contexts + * ------------------------------------------------ + * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This + * is purely an implementation details. + * + * The contract is simply this: + * + * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value) + * will also succeed. + * + * Inheritance happens to capture this in a natural way.

The `expression` is evaluated against each item and the output is used + * for comparing with other items. + * + * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in + * ascending order. + * + * The comparison is done using the `comparator` function. If none is specified, a default, built-in + * comparator is used (see below for details - in a nutshell, it compares numbers numerically and + * strings alphabetically). + * + * ### Under the hood + * + * Ordering the specified `collection` happens in two phases: + * + * 1. All items are passed through the predicate (or predicates), and the returned values are saved + * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed + * through a predicate that extracts the value of the `label` property, would be transformed to: + * ``` + * { + * value: 'foo', + * type: 'string', + * index: ... + * } + * ``` + * 2. The comparator function is used to sort the items, based on the derived values, types and + * indices. + * + * If you use a custom comparator, it will be called with pairs of objects of the form + * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal + * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the + * second, or `1` otherwise. + * + * In order to ensure that the sorting will be deterministic across platforms, if none of the + * specified predicates can distinguish between two items, `orderBy` will automatically introduce a + * dummy predicate that returns the item's index as `value`. + * (If you are using a custom comparator, make sure it can handle this predicate as well.) + * + * If a custom comparator still can't distinguish between two items, then they will be sorted based + * on their index using the built-in comparator. + * + * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted + * value for an item, `orderBy` will try to convert that object to a primitive value, before passing + * it to the comparator. The following rules govern the conversion: + * + * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be + * used instead.
        + * (If the object has a `valueOf()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that + * returns a primitive, its return value will be used instead.
        + * (If the object has a `toString()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 3. No conversion; the object itself is used. + * + * ### The default comparator + * + * The default, built-in comparator should be sufficient for most usecases. In short, it compares + * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to + * using their index in the original collection, and sorts values of different types by type. + * + * More specifically, it follows these steps to determine the relative order of items: + * + * 1. If the compared values are of different types, compare the types themselves alphabetically. + * 2. If both values are of type `string`, compare them alphabetically in a case- and + * locale-insensitive way. + * 3. If both values are objects, compare their indices instead. + * 4. Otherwise, return: + * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). + * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). + * - `1`, otherwise. + * + * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being + * saved as numbers and not strings. + * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e. + * `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to + * other values. + * + * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. + * @param {(Function|string|Array.)=} expression - A predicate (or list of + * predicates) to be used by the comparator to determine the order of elements. + * + * Can be one of: + * + * - `Function`: A getter function. This function will be called with each item as argument and + * the return value will be used for sorting. + * - `string`: An AngularJS expression. This expression will be evaluated against each item and the + * result will be used for sorting. For example, use `'label'` to sort by a property called + * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` + * property.
        + * (The result of a constant expression is interpreted as a property name to be used for + * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a + * property called `special name`.)
        + * An expression can be optionally prefixed with `+` or `-` to control the sorting direction, + * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, + * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. + * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the + * relative order of two items, the next predicate is used as a tie-breaker. + * + * **Note:** If the predicate is missing or empty then it defaults to `'+'`. + * + * @param {boolean=} reverse - If `true`, reverse the sorting order. + * @param {(Function)=} comparator - The comparator function used to determine the relative order of + * value pairs. If omitted, the built-in comparator will be used. + * + * @returns {Array} - The sorted array. + * + * + * @example + * ### Ordering a table with `ngRepeat` + * + * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by + * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means + * it defaults to the built-in comparator. + * + + +

        * - * To be secure by default, you want to ensure that any such bindings are disallowed unless you can - * determine that something explicitly says it's safe to use a value for binding in that - * context.

However, the parsed components will not be set if the URL assigned did not specify - * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We - * work around that by performing the parsing in a 2nd step by taking a previously normalized - * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the - * properties such as protocol, hostname, port, etc. + * If the `name` attribute is specified, the form controller is published onto the current scope under + * this name. * - * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one - * uses the inner HTML approach to assign the URL as part of an HTML snippet - - * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL. - * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception. - * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that - * method and IE < 8 is unsupported. + * ## Alias: {@link ng.directive:ngForm `ngForm`} * - * References: - * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement - * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html - * http://url.spec.whatwg.org/#urlutils - * https://github.com/angular/angular.js/pull/2902 - * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/ + * In AngularJS, forms can be nested.

Nested forms can be useful, for example, if the validity of a sub-group + * of controls needs to be determined. * - * @function - * @param {string} url The URL to be parsed. - * @description Normalizes and parses a URL. - * @returns {object} Returns the normalized URL as a dictionary. + * ## CSS classes + * - `ng-valid` is set if the form is valid. + * - `ng-invalid` is set if the form is invalid. + * - `ng-pending` is set if the form is pending. + * - `ng-pristine` is set if the form is pristine. + * - `ng-dirty` is set if the form is dirty. + * - `ng-submitted` is set if the form was submitted. * - * | member name | Description | - * |---------------|----------------| - * | href | A normalized version of the provided URL if it was not an absolute URL | - * | protocol | The protocol including the trailing colon | - * | host | The host and port (if the port is non-default) of the normalizedUrl | - * | search | The search params, minus the question mark | - * | hash | The hash string, minus the hash symbol - * | hostname | The hostname - * | port | The port, without ":" - * | pathname | The pathname, beginning with "/" + * Keep in mind that ngAnimate can detect each of these classes when added and removed. + * + * + * ## Submitting a form and preventing the default action + * + * Since the role of forms in client-side AngularJS applications is different than in classical + * roundtrip apps, it is desirable for the browser not to translate the form submission into a full + * page reload that sends the data to the server. Instead some javascript logic should be triggered + * to handle the form submission in an application-specific way. + * + * For this reason, AngularJS prevents the default action (form submission to the server) unless the + * `` element has an `action` attribute specified. + * + * You can use one of the following two ways to specify what javascript method should be called when + * a form is submitted: + * + * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element + * - {@link ng.directive:ngClick ngClick} directive on the first + * button or input field of type submit (input[type=submit]) + * + * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} + * or {@link ng.directive:ngClick ngClick} directives. + * This is because of the following form submission rules in the HTML specification: + * + * - If a form has only one input field then hitting enter in this field triggers form submit + * (`ngSubmit`) + * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter + * doesn't trigger submit + * - if a form has one or more input fields and one or more buttons or input[type=submit] then + * hitting enter in any of the input fields will trigger the click handler on the *first* button or + * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) + * + * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is + * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * @animations + * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. + * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any + * other validations that are performed within the form. Animations in ngForm are similar to how + * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well + * as JS animations. + * + * The following example shows a simple way to utilize CSS transitions to style a form element + * that has been rendered as invalid after it has been validated: + * + * 
        +     * //be sure to include ngAnimate as a module to hook into more
+     * //advanced animations
+     * .my-form {
+     *   transition:0.5s linear all;
+     *   background: white;
+     * }
+     * .my-form.ng-invalid {
+     *   background: red;
+     *   color:white;
+     * }
+     *
        + * + * @example + + + + + + userType: + Required!
        + userType = {{userType}}
        + myForm.input.$valid = {{myForm.input.$valid}}
        + myForm.input.$error = {{myForm.input.$error}}
        + myForm.$valid = {{myForm.$valid}}
        + myForm.$error.required = {{!!myForm.$error.required}}
        + +         + + it('should initialize to model', function() { + var userType = element(by.binding('userType')); + var valid = element(by.binding('myForm.input.$valid')); + + expect(userType.getText()).toContain('guest'); + expect(valid.getText()).toContain('true'); + }); + + it('should be invalid if empty', function() { + var userType = element(by.binding('userType')); + var valid = element(by.binding('myForm.input.$valid')); + var userInput = element(by.model('userType')); + + userInput.clear(); + userInput.sendKeys(''); + + expect(userType.getText()).toEqual('userType ='); + expect(valid.getText()).toContain('false'); + }); + +

+     * @name ngList
+     * @restrict A
+     * @priority 100
+     *
+     * @param {string=} ngList optional delimiter that should be used to split the value.
      *
      * @description
-     * Creates a binding that will innerHTML the result of evaluating the `expression` into the current
-     * element in a secure way.  By default, the innerHTML-ed content will be sanitized using the {@link
-        * ngSanitize.$sanitize $sanitize} service.  To utilize this functionality, ensure that `$sanitize`
-     * is available, for example, by including {@link ngSanitize} in your module's dependencies (not in
-     * core Angular.)  You may also bypass sanitization for values you know are safe. To do so, bind to
-     * an explicitly trusted value via {@link ng.$sce#trustAsHtml $sce.trustAsHtml}.  See the example
-     * under {@link ng.$sce#Example Strict Contextual Escaping (SCE)}.
+     * Text input that converts between a delimited string and an array of strings. The default
+     * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
+     * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
+     *
+     * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
+     * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
+     *   list item is respected. This implies that the user of the directive is responsible for
+     *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
+     *   tab or newline character.
+     * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
+     *   when joining the list items back together) and whitespace around each list item is stripped
+     *   before it is added to the model.
      *
-     * Note: If a `$sanitize` service is unavailable and the bound value isn't explicitly trusted, you
-     * will have an exception (instead of an exploit.)

-     * @restrict AC

+     *     return value.toUpperCase();
+     *   }
+     * }
+     * ngModel.$formatters.push(format);
+     * ```
      *
-     * @description
-     * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
-     * an expression that represents all classes to be added.
+     * @property {Object.} $validators A collection of validators that are applied
+     *      whenever the model value changes. The key value within the object refers to the name of the
+     *      validator while the function refers to the validation operation. The validation operation is
+     *      provided with the model value as an argument and must return a true or false value depending
+     *      on the response of that validation.
      *
-     * The directive operates in three different ways, depending on which of three types the expression
-     * evaluates to:
+     * ```js
+     * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
+     *   var value = modelValue || viewValue;
+     *   return /[0-9]+/.test(value) &&
+     *          /[a-z]+/.test(value) &&
+     *          /[A-Z]+/.test(value) &&
+     *          /\W+/.test(value);
+     * };
+     * ```
      *
-     * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
-     * names.
+     * @property {Object.} $asyncValidators A collection of validations that are expected to
+     *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
+     *      is expected to return a promise when it is run during the model validation process. Once the promise
+     *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
+     *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
+     *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
+     *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
+     *      will only run once all synchronous validators have passed.
      *
-     * 2. If the expression evaluates to an array, each element of the array should be a string that is
-     * one or more space-delimited class names.
+     * Please note that if $http is used then it is important that the server returns a success HTTP response code
+     * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
      *
-     * 3. If the expression evaluates to an object, then for each key-value pair of the
-     * object with a truthy value the corresponding key is used as a class name.
+     * ```js
+     * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
+     *   var value = modelValue || viewValue;
+     *
+     *   // Lookup user by username
+     *   return $http.get('/api/users/' + value).
+     *      then(function resolved() {
+     *        //username exists, this means validation fails
+     *        return $q.reject('exists');
+     *      }, function rejected() {
+     *        //username does not exist, therefore this validation passes
+     *        return true;
+     *      });
+     * };
+     * ```
      *
-     * The directive won't add duplicate classes if a particular class was already set.
+     * @property {Array.} $viewChangeListeners Array of functions to execute whenever
+     *     a change to {@link ngModel.NgModelController#$viewValue `$viewValue`} has caused a change
+     *     to {@link ngModel.NgModelController#$modelValue `$modelValue`}.
+     *     It is called with no arguments, and its return value is ignored.
+     *     This can be used in place of additional $watches against the model value.
      *
-     * When the expression changes, the previously added classes are removed and only then the
-     * new classes are added.
+     * @property {Object} $error An object hash with all failing validator ids as keys.
+     * @property {Object} $pending An object hash with all pending validator ids as keys.
      *
-     * @animations
-     * add - happens just before the class is applied to the element
-     * remove - happens just before the class is removed from the element
+     * @property {boolean} $untouched True if control has not lost focus yet.
+     * @property {boolean} $touched True if control has lost focus.
+     * @property {boolean} $pristine True if user has not interacted with the control yet.
+     * @property {boolean} $dirty True if user has already interacted with the control.
+     * @property {boolean} $valid True if there is no error.
+     * @property {boolean} $invalid True if at least one error on the control.
+     * @property {string} $name The name attribute of the control.
      *
-     * @element ANY
-     * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
-     *   of the evaluation can be a string representing space delimited class
-     *   names, an array, or a map of class names to boolean values. In the case of a map, the
-     *   names of the properties whose values are truthy will be added as css classes to the

+     * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
+     * The controller contains services for data-binding, validation, CSS updates, and value formatting
+     * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
+     * listening to DOM events.
+     * Such DOM related logic should be provided by other directives which make use of
+     * `NgModelController` for data-binding to control elements.
+     * AngularJS provides this DOM logic for most {@link input `input`} elements.
+     * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
+     *
+     * @example
+     * ### Custom Control Example
+     * This example shows how to use `NgModelController` with a custom control to achieve
+     * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+     * collaborate together to achieve the desired result.
+     *
+     * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+     * contents be edited in place by the user.
      *
-     * @example Example that demonstrates basic bindings via ngClass directive.
-     
+     * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+     * module to automatically remove "bad" content like inline event listener (e.g. ``).
+     * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+     * that content using the `$sce` service.
+     *
+     * 
+     
+     [contenteditable] {
+        border: 1px solid black;
+        background-color: white;
+        min-height: 20px;
+      }
+
+     .ng-invalid {
+        border: 1px solid red;
+      }
+
+     
+     
+     angular.module('customControl', ['ngSanitize']).
+     directive('contenteditable', ['$sce', function($sce) {
+          return {
+            restrict: 'A', // only activate on element attribute
+            require: '?ngModel', // get a hold of NgModelController
+            link: function(scope, element, attrs, ngModel) {
+              if (!ngModel) return; // do nothing if no ng-model

+              ngModel.$render = function() {
+                element.html($sce.getTrustedHtml(ngModel.$viewValue || ''));
+              };

+              element.on('blur keyup change', function() {
+                scope.$evalAsync(read);
+              });
+              read(); // initialize
+
+              // Write data to the model
+              function read() {
+                var html = element.html();
+                // When we clear the content editable the browser leaves a 
         behind
+                // If strip-br attribute is provided then we strip this out
+                if (attrs.stripBr && html === '
        ') {
+                  html = '';
+                }
+                ngModel.$setViewValue(html);
+              }

+         * future event.
+         *
+         * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
+         * depend on special events such as `blur`, there can be a period when the `$viewValue` is out of
+         * sync with the ngModel's `$modelValue`.

+         * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
+         * and reset the input to the last committed view value.

+         * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
+         * programmatically before these debounced/future events have resolved/occurred, because AngularJS's
+         * dirty checking mechanism is not able to tell whether the model has actually changed or not.
+         *
+         * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
+         * input which may have such events pending. This is important in order to make sure that the
+         * input field will be updated with the new model value and any pending operations are cancelled.
+         *
+         * @example
+         * 
+         *   
+         *     angular.module('cancel-update-example', [])

+         *         
        1. Type something in the input. You will see that the model is not yet updated
          2. 
+         *         
        2. Press the Escape key.
+         *           
            
+         *             
          1.  In the first example, nothing happens, because the model is already '', and no
+         *             update is detected. If you blur the input, the model will be set to the current view.
+         *             
            2. 
+         *             
          2.  In the second example, the pending update is cancelled, and the input is set back
+         *             to the last committed view value (''). Blurring the input does nothing.
+         *

-     * @name ngCloak
-     * @restrict AC
-     *
-     * @description
-     * The `ngCloak` directive is used to prevent the Angular html template from being briefly
-     * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
-     * directive to avoid the undesirable flicker effect caused by the html template display.
-     *
-     * The directive can be applied to the `` element, but the preferred usage is to apply
-     * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
-     * of the browser view.
-     *
-     * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
-     * `angular.min.js`.
-     * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
-     *
-     * ```css
-     * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
-     * ```
-     *
-     * When this css rule is loaded by the browser, all html elements (including their children) that
-     * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
-     * during the compilation of the template it deletes the `ngCloak` element attribute, making
-     * the compiled element visible.
-     *
-     * For the best result, the `angular.js` script must be loaded in the head section of the html
-     * document; alternatively, the css rule above must be included in the external stylesheet of the
-     * application.
-     *
-     * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
-     * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
-     * class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below.
-     *
-     * @element ANY
-     *
-     * @example

-

-     *
-     * @description
-     * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
-     * supports the principles behind the Model-View-Controller design pattern.
-     *
-     * MVC components in angular:
-     *
-     * * Model — The Model is scope properties; scopes are attached to the DOM where scope properties
-     *   are accessed through bindings.
-     * * View — The template (HTML with data bindings) that is rendered into the View.
-     * * Controller — The `ngController` directive specifies a Controller class; the class contains business
-     *   logic behind the application to decorate the scope with functions and values
-     *
-     * Note that you can also attach controllers to the DOM by declaring it in a route definition
-     * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
-     * again using `ng-controller` in the template itself.  This will cause the controller to be attached
-     * and executed twice.
-     *
-     * @element ANY
-     * @scope
-     * @param {expression} ngController Name of a globally accessible constructor function or an
-     *     {@link guide/expression expression} that on the current scope evaluates to a
-     *     constructor function. The controller instance can be published into a scope property
-     *     by specifying `as propertyName`.
-     *
-     * @example
-     * Here is a simple form for editing user contact information. Adding, removing, clearing, and
-     * greeting are methods declared on the controller (see source tab). These methods can
-     * easily be called from the angular markup. Notice that the scope becomes the `this` for the
-     * controller's instance. This allows for easy access to the view data from the controller. Also
-     * notice that any changes to the data are automatically reflected in the View without the need
-     * for a manual update. The example is shown in two different declaration styles you may use
-     * according to preference.

+         * @description
+         * Update the view value.
+         *
+         * This method should be called when a control wants to change the view value; typically,
+         * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
+         * directive calls it when the value of the input changes and {@link ng.directive:select select}
+         * calls it when an option is selected.
+         *
+         * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+         * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+         * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
+         * `$asyncValidators` are called and the value is applied to `$modelValue`.
+         * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
+         * all the registered change listeners, in the `$viewChangeListeners` list are called.
+         *
+         * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+         * and the `default` trigger is not listed, all those actions will remain pending until one of the
+         * `updateOn` events is triggered on the DOM element.
+         * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+         * directive is used with a custom debounce for this particular event.
+         * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+         * is specified, once the timer runs out.
+         *
+         * When used with standard inputs, the view value will always be a string (which is in some cases
+         * parsed into another type, such as a `Date` object for `input[date]`.)
+         * However, custom controls might also pass objects to this method. In this case, we should make
+         * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not

+         * - the `$modelValue` is run through the {@link ngModel.NgModelController#$formatters $formatters}

+         * - the `ng-empty` or `ng-not-empty` class is set on the element
+         * - if the `$viewValue` has changed:
+         *   - {@link ngModel.NgModelController#$render $render} is called on the control
+         *   - the {@link ngModel.NgModelController#$validators $validators} are run and
+         *   the validation status is set.
+         *
+         * This method is called by ngModel internally when the bound scope value changes.
+         * Application developers usually do not have to call this function themselves.
+         *
+         * This function can be used when the `$viewValue` or the rendered DOM value are not correctly
+         * formatted and the `$modelValue` must be run through the `$formatters` again.
+         *
+         * @example
+         * Consider a text input with an autocomplete list (for fruit), where the items are
+         * objects with a name and an id.
+         * A user enters `ap` and then selects `Apricot` from the list.
+         * Based on this, the autocomplete widget will call `$setViewValue({name: 'Apricot', id: 443})`,
+         * but the rendered value will still be `ap`.
+         * The widget can then call `ctrl.$processModelValue()` to run the model -> view
+         * pipeline again, which formats the object to the string `Apricot`,
+         * then updates the `$viewValue`, and finally renders it in the DOM.

      * @description
-     * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
+     * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+     * property on the scope using {@link ngModel.NgModelController NgModelController},
+     * which is created and exposed by this directive.
      *
-     * This is necessary when developing things like Google Chrome Extensions.
+     * `ngModel` is responsible for:
      *
-     * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
-     * For us to be compatible, we just need to implement the "getterFn" in $parse without violating
-     * any of these restrictions.
+     * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+     *   require.
+     * - Providing validation behavior (i.e. required, number, email, url).
+     * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+     * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
+     *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
+     * - Registering the control with its parent {@link ng.directive:form form}.
      *
-     * AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp`
-     * directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will
-     * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
-     * be raised.
+     * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+     * current scope. If the property doesn't already exist on this scope, it will be created
+     * implicitly and added to the scope.
      *
-     * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically
-     * includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}).
-     * To make those directives work in CSP mode, include the `angular-csp.css` manually.
+     * For best practices on using `ngModel`, see:
      *
-     * In order to use this feature put the `ngCsp` directive on the root element of the application.
+     *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
      *
-     * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+     * For basic examples, how to use `ngModel`, see:
      *
-     * @example
-     * This example shows how to apply the `ngCsp` directive to the `html` tag.
-     ```html
-     
-     
-     ...
-     ...
-     
-     ```

-// ngCsp is not implemented as a proper directive any more, because we need it be processed while we bootstrap

-     * @ngdoc directive
-     * @name ngDblclick
+     * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
+     * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
+     * if the select is given the `multiple` attribute.
      *
-     * @description
-     * The `ngDblclick` directive allows you to specify custom behavior on a dblclick event.
+     * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
+     * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
+     * not trigger a re-rendering of the model.

+     * ## CSS classes
+     * The following CSS classes are added and removed on the associated input/select/textarea element
+     * depending on the validity of the model.
      *
-     * @example
-     
-     
-     
-     count: {{count}}
-     
-     
-     */
-
-
-    /**
-     * @ngdoc directive
-     * @name ngMousedown
+     *  - `ng-valid`: the model is valid
+     *  - `ng-invalid`: the model is invalid
+     *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
+     *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+     *  - `ng-pristine`: the control hasn't been interacted with yet
+     *  - `ng-dirty`: the control has been interacted with
+     *  - `ng-touched`: the control has been blurred
+     *  - `ng-untouched`: the control hasn't been blurred
+     *  - `ng-pending`: any `$asyncValidators` are unfulfilled
+     *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+     *     by the {@link ngModel.NgModelController#$isEmpty} method
+     *  - `ng-not-empty`: the view contains a non-empty value

+     * @animations
+     * Animations within models are triggered when any of the associated CSS classes are added and removed
+     * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+     * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+     * The animations that are triggered within ngModel are similar to how they work in ngClass and
+     * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+     *
+     * The following example shows a simple way to utilize CSS transitions to style an input element
+     * that has been rendered as invalid after it has been validated:
+     *
+     * 
        +     * //be sure to include ngAnimate as a module to hook into more
+     * //advanced animations
+     * .my-input {
+     *   transition:0.5s linear all;
+     *   background: white;
+     * }
+     * .my-input.ng-invalid {
+     *   background: red;
+     *   color:white;
+     * }
+     * 
        
      *
      * @example
-     
+     * ### Basic Usage
+     * 
      
-     
-     count: {{count}}
+     
+     
+     
        
+     Update input to see transitions when valid/invalid.
+     Integer is a valid value.

      *
-     * @element ANY
-     * @priority 0

+     * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
+     * function that returns a representation of the model when called with zero arguments, and sets
+     * the internal state of a model when called with an argument. It's sometimes useful to use this
+     * for models that have an internal representation that's different from what the model exposes
+     * to the view.
+     *
+     * 
        
+     * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
+     * frequently than other parts of your code.
+     * 
        
+     *
+     * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+     * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+     * a `
        `, which will enable this behavior for all ``s within it. See
+     * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
+     *
+     * The following example shows how to use `ngModel` with a getter/setter:
      *
      * @example
-     
+     * 
      
-     
-     count: {{count}}
+     
        
+     
+     
+     
+     
        user.name = 
        
+     
        
              
-             
+     
+     angular.module('getterSetterExample', [])
+     .controller('ExampleController', ['$scope', function($scope) {
+           var _name = 'Brian';
+           $scope.user = {
+             name: function(newName) {
+              // Note that newName can be undefined for two reasons:
+              // 1. Because it is called as a getter and thus called with no arguments
+              // 2. Because the property should actually be set to undefined. This happens e.g. if the
+              //    input is invalid
+              return arguments.length ? (_name = newName) : _name;
+             }
+           };
+         }]);

+     *   
+     *         
+     *
+     *
+     * ## Model updates and validation
+     *
+     * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
+     * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
+     * the model will still be updated even if the value is invalid.
+     *
+     *
+     * ## Connecting to the scope
+     *
+     * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
+     * on the scope refers to a "getter/setter" function rather than the value itself.
+     *
+     * The following example shows how to bind to getter/setters:
+     *
+     * 
+     *   
+     *     
        
+     *       
        
+     *         
+     *       
        
+     *       
        user.name = 
        
+     *     
        
+     *           
+     *   
+     *     angular.module('getterSetterExample', [])
+     *       .controller('ExampleController', ['$scope', function($scope) {
+     *         var _name = 'Brian';
+     *         $scope.user = {
+     *           name: function(newName) {
+     *             return angular.isDefined(newName) ? (_name = newName) : _name;
+     *           }
+     *         };
+     *       }]);
+     *   
+     *         
+     *
+     *
+     * ## Specifying timezones
+     *
+     * You can specify the timezone that date/time input directives expect by providing its name in the
+     * `timezone` property.
+     *
+     *
+     * ## Programmatically changing options
+     *
+     * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
+     * watched for changes. However, it is possible to override the options on a single
+     * {@link ngModel.NgModelController} instance with
+     * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
+     *
+     *
+     * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
+     *   and its descendents. Valid keys are:
+     *   - `updateOn`: string specifying which event should the input be bound to. You can set several
+     *     events using an space delimited list. There is a special event called `default` that
+     *     matches the default events belonging to the control. These are the events that are bound to
+     *     the control, and when fired, update the `$viewValue` via `$setViewValue`.
+     *
+     *     `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event,
+     *     since different control types use different default events.
+     *
+     *     See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates
+ *     Triggering and debouncing model updates}.
+     *
+     *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
+     *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
+     *     custom value for each event. For example:
+     *     ```
+     *     ng-model-options="{
+     *       updateOn: 'default blur click',
+     *       debounce: { 'default': 500, 'blur': 0 }
+     *     }"
+     *     ```
+     *
+     *     "default" also applies to all events that are listed in `updateOn` but are not
+     *     listed in `debounce`, i.e. "click" would also be debounced by 500 milliseconds.
+     *
+     *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
+     *     not validate correctly instead of the default behavior of setting the model to undefined.
+     *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
+     *     `ngModel` as getters/setters.
+     *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
+     *     ``, ``, ... . It understands UTC/GMT and the
+     *     continental US time zone abbreviations, but for general use, use a time zone offset, for
+     *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+     *     If not specified, the timezone of the browser will be used.
