- *
- * This is jQuery's low-level AJAX implementation. See $.get, $.post etc. for

- *
- * $.ajax() returns the XMLHttpRequest that it creates. In most cases you won't

- * abort the request manually.
- *
- * '''Note:''' If you specify the dataType option described below, make sure
- * the server sends the correct MIME type in the response (eg. xml as "text/xml").
- * Sending the wrong MIME type can lead to unexpected problems in your script.
- * See [[Specifying the Data Type for AJAX Requests]] for more information.
- *
- * Supported datatypes are (see dataType option):
- *
- * "xml": Returns a XML document that can be processed via jQuery.
- *
- * "html": Returns HTML as plain text, included script tags are evaluated.
- *
- * "script": Evaluates the response as Javascript and returns it as plain text.
- *
- * "json": Evaluates the response as JSON and returns a Javascript Object
- *
- * $.ajax() takes one argument, an object of key/value pairs, that are
- * used to initalize and handle the request. These are all the key/values that can
- * be used:
- *
- * (String) url - The URL to request.
- *
- * (String) type - The type of request to make ("POST" or "GET"), default is "GET".
- *
- * (String) dataType - The type of data that you're expecting back from
- * the server. No default: If the server sends xml, the responseXML, otherwise
- * the responseText is passed to the success callback.
- *
- * (Boolean) ifModified - Allow the request to be successful only if the
- * response has changed since the last request. This is done by checking the
- * Last-Modified header. Default value is false, ignoring the header.
- *
- * (Number) timeout - Local timeout in milliseconds to override global timeout, eg. to give a
- * single request a longer timeout while all others timeout after 1 second.
- * See $.ajaxTimeout() for global timeouts.
- *
- * (Boolean) global - Whether to trigger global AJAX event handlers for
- * this request, default is true. Set to false to prevent that global handlers
- * like ajaxStart or ajaxStop are triggered.
- *
- * (Function) error - A function to be called if the request fails. The
- * function gets passed tree arguments: The XMLHttpRequest object, a
- * string describing the type of error that occurred and an optional
- * exception object, if one occured.
- *
- * (Function) success - A function to be called if the request succeeds. The
- * function gets passed one argument: The data returned from the server,
- * formatted according to the 'dataType' parameter.
- *
- * (Function) complete - A function to be called when the request finishes. The
- * function gets passed two arguments: The XMLHttpRequest object and a
- * string describing the type of success of the request.
- *
- * (Object|String) data - Data to be sent to the server. Converted to a query
- * string, if not already a string. Is appended to the url for GET-requests.
- * See processData option to prevent this automatic processing.
- *
- * (String) contentType - When sending data to the server, use this content-type.
- * Default is "application/x-www-form-urlencoded", which is fine for most cases.
- *
- * (Boolean) processData - By default, data passed in to the data option as an object
- * other as string will be processed and transformed into a query string, fitting to
- * the default content-type "application/x-www-form-urlencoded". If you want to send
- * DOMDocuments, set this option to false.
- *
- * (Boolean) async - By default, all requests are sent asynchronous (set to true).
- * If you need synchronous requests, set this option to false.
- *
- * (Function) beforeSend - A pre-callback to set custom headers etc., the
- * XMLHttpRequest is passed as the only argument.
- *
- * @example $.ajax({
- * type: "GET",
- * url: "test.js",
- * dataType: "script"
- * })
- * @desc Load and execute a JavaScript file.
- *
