/**
 * HTML elements and other resources for web-based applications that need to
 * interact with the browser and the DOM (Document Object Model).
 *
 * This library includes DOM element types, CSS styling, local storage,
 * media, speech, events, and more.
 * To get started,
 * check out the [Element] class, the base class for many of the HTML
 * DOM types.
 *
 * ## Other resources
 *
 * * If you've never written a web app before, try our
 * tutorials&mdash;[A Game of Darts](http://dartlang.org/docs/tutorials).
 *
 * * To see some web-based Dart apps in action and to play with the code,
 * download
 * [Dart Editor](http://www.dartlang.org/#get-started)
 * and run its built-in examples.
 *
 * * For even more examples, see
 * [Dart HTML5 Samples](https://github.com/dart-lang/dart-html5-samples)
 * on Github.

 /**
  * A client-side XHR request for getting data from a URL,
  * formally known as XMLHttpRequest.
  *
  * HttpRequest can be used to obtain data from HTTP and FTP protocols,
  * and is useful for AJAX-style page updates.
  *
  * The simplest way to get the contents of a text file, such as a
  * JSON-formatted file, is with [getString].
  * For example, the following code gets the contents of a JSON file
  * and prints its length:
  *
  *     var path = 'myData.json';
  *     HttpRequest.getString(path)
  *         .then((String fileContents) {
  *           print(fileContents.length);
  *         })
  *         .catchError((Error error) {
  *           print(error.toString());
  *         });
  *
  * ## Fetching data from other servers
  *
  * For security reasons, browsers impose restrictions on requests
  * made by embedded apps.
  * With the default behavior of this class,
  * the code making the request must be served from the same origin
  * (domain name, port, and application layer protocol)
  * as the requested resource.
  * In the example above, the myData.json file must be co-located with the
  * app that uses it.
  * You might be able to
  * [get around this restriction](http://www.dartlang.org/articles/json-web-service/#a-note-on-cors-and-httprequest)
  * by using CORS headers or JSONP.
  *
  * ## Other resources
  *
  * * [Fetch Data Dynamically](https://www.dartlang.org/docs/tutorials/fetchdata/),
  * a tutorial from _A Game of Darts_,
  * shows two different ways to use HttpRequest to get a JSON file.

   * Creates and sends a URL request for the specified [url].
   *
   * By default `request` will perform an HTTP GET request, but a different
   * method (`POST`, `PUT`, `DELETE`, etc) can be used by specifying the
   * [method] parameter. (See also [HttpRequest.postFormData] for `POST` 
   * requests only.
   *
   * The Future is completed when the response is available.
   *
   * If specified, `sendData` will send data in the form of a [ByteBuffer],
   * [Blob], [Document], [String], or [FormData] along with the HttpRequest.
   *
   * If specified, [responseType] sets the desired response format for the
   * request. By default it is [String], but can also be 'arraybuffer', 'blob', 
   * 'document', 'json', or 'text'. See also [HttpRequest.responseType] 
   * for more information.
   *
   * The [withCredentials] parameter specified that credentials such as a cookie
   * (already) set in the header or
   * [authorization headers](http://tools.ietf.org/html/rfc1945#section-10.2)
   * should be specified for the request. Details to keep in mind when using
   * credentials:
   *
   * * Using credentials is only useful for cross-origin requests.
   * * The `Access-Control-Allow-Origin` header of `url` cannot contain a wildcard (*).
   * * The `Access-Control-Allow-Credentials` header of `url` must be set to true.
   * * If `Access-Control-Expose-Headers` has not been set to true, only a subset of all the response headers will be returned when calling [getAllRequestHeaders].
   *
   * The following is equivalent to the [getString] sample above:
   *
   *     var name = Uri.encodeQueryComponent('John');
   *     var id = Uri.encodeQueryComponent('42');
   *     HttpRequest.request('users.json?name=$name&id=$id')
   *       .then((HttpRequest resp) {
   *         // Do something with the response.
   *     });
   *
   * Here's an example of submitting an entire form with [FormData].
   *
   *     var myForm = querySelector('form#myForm');
   *     var data = new FormData(myForm);
   *     HttpRequest.request('/submit', method: 'POST', sendData: data)
   *       .then((HttpRequest resp) {
   *         // Do something with the response.
   *     });
   *
   * Note that requests for file:// URIs are only supported by Chrome extensions
   * with appropriate permissions in their manifest. Requests to file:// URIs
   * will also never fail- the Future will always complete successfully, even
   * when the file cannot be found.
   *
   * See also: [authorization headers](http://en.wikipedia.org/wiki/Basic_access_authentication).

/**
 * The type used by the

 *     window.localStorage['key2'] = 'val2';
 *     window.localStorage['key3'] = 'val3';
 *     assert(window.localStorage['key3'] == 'val3');

/**
 * A custom KeyboardEvent that attempts to eliminate cross-browser
 * inconsistencies, and also provide both keyCode and charCode information
 * for all key events (when such information can be determined).
 *
 * KeyEvent tries to provide a higher level, more polished keyboard event
 * information on top of the "raw" [KeyboardEvent].
 *
 * The mechanics of using KeyEvents is a little different from the underlying
 * [KeyboardEvent]. To use KeyEvents, you need to create a stream and then add
 * KeyEvents to the stream, rather than using the [EventTarget.dispatchEvent].
 * Here's an example usage:
 *
 *     // Initialize a stream for the KeyEvents:
 *     var stream = KeyEvent.keyPressEvent.forTarget(document.body);
 *     // Start listening to the stream of KeyEvents.
 *     stream.listen((keyEvent) =>
 *         window.console.log('KeyPress event detected ${keyEvent.charCode}'));
 *     ...
 *     // Add a new KeyEvent of someone pressing the 'A' key to the stream so
 *     // listeners can know a KeyEvent happened.
 *     stream.add(new KeyEvent('keypress', keyCode: 65, charCode: 97));
 *
 * This class is very much a work in progress, and we'd love to get information
 * on how we can make this class work with as many international keyboards as
 * possible. Bugs welcome!
