## Overview

Wraps a raw DOM element or HTML string as a jQuery element.

If jQuery is available, `angular.element` is an alias for the jQuery function. If jQuery is not available, `angular.element` delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or jqLite.

jqLite is a tiny, API-compatible subset of jQuery that allows AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most commonly needed functionality with the goal of having a very small footprint.

To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the `ngJq` directive to specify that jqlite should be used over jQuery, or to use a specific version of jQuery if multiple versions exist on the page.

Note: All element references in AngularJS are always wrapped with jQuery or jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
Note: Keep in mind that this function will not find elements by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)` or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

## AngularJS's jqLite

jqLite provides only the following jQuery methods:

- `addClass()` - Does not support a function as first argument
- `after()`
- `append()` - Contrary to jQuery, this doesn't clone elements so will not work correctly when invoked on a jqLite object containing more than one DOM node
- `attr()` - Does not support functions as parameters
- `bind()` (deprecated, use `on()`) - Does not support namespaces, selectors or eventData
- `children()` - Does not support selectors
- `clone()`
- `contents()`
- `css()` - Only retrieves inline-styles, does not call `getComputedStyle()`. As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
- `data()`
- `detach()`
- `empty()`
- `eq()`
- `find()` - Limited to lookups by tag name
- `hasClass()`
- `html()`
- `next()` - Does not support selectors
- `on()` - Does not support namespaces, selectors or eventData
- `off()` - Does not support namespaces, selectors or event object as parameter
- `one()` - Does not support namespaces or selectors
- `parent()` - Does not support selectors
- `prepend()`
- `prop()`
- `ready()` (deprecated, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
- `remove()`
- `removeAttr()` - Does not support multiple attributes
- `removeClass()` - Does not support a function as first argument
- `removeData()`
- `replaceWith()`
- `text()`
- `toggleClass()` - Does not support a function as first argument
- `triggerHandler()` - Passes a dummy event object to handlers
- `unbind()` (deprecated, use `off()`) - Does not support namespaces or event object as parameter
- `val()`
- `wrap()`

## jQuery/jqLite Extras

AngularJS also provides the following additional methods and events to both jQuery and jqLite:

### Events

- `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM element before it is removed.

### Methods

- `controller(name)` - retrieves the controller of the current element or its parent. By default retrieves controller associated with the `ngController` directive. If `name` is provided as camelCase directive name, then the controller for this directive will be retrieved (e.g. `'ngModel'`).
- `injector()` - retrieves the injector of the current element or its parent.
- `scope()` - retrieves the scope of the current element or its parent. Requires Debug Data to be enabled.
- `isolateScope()` - retrieves an isolate scope if one is attached directly to the current element. This getter should be used only on elements that contain a directive which starts a new isolate scope. Calling `scope()` on this element always returns the original non-isolate scope. Requires Debug Data to be enabled.
- `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top parent element is reached.

## Known Issues

You cannot spy on `angular.element` if you are using Jasmine version 1.x. See https://github.com/angular/angular.js/issues/14251 for more information.
