|
* higher-level abstractions that are often easier to understand and use,
|
|
* but don't offer as much functionality (such as error callbacks).
|
|
*
|
|
* $.ajax() returns the XMLHttpRequest that it creates. In most cases you won't
|
|
* need that object to manipulate directly, but it is available if you need to
|
|
* 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.
|
|
*
|
|
* @example $.ajax({
|
|
* type: "POST",
|
|
* url: "some.php",
|
|
* data: "name=John&location=Boston",
|
|
* success: function(msg){
|
|
* alert( "Data Saved: " + msg );
|
|
* }
|
|
* });
|
|
* @desc Save some data to the server and notify the user once its complete.
|
|
*
|
|
* @example var html = $.ajax({
|
|
* url: "some.php",
|
|
* async: false
|
|
* }).responseText;
|
|
* @desc Loads data synchronously. Blocks the browser while the requests is active.
|
|
* It is better to block user interaction by other means when synchronization is
|
|
* necessary.
|
|
*
|
|
* @example var xmlDocument = [create xml document];
|
|
* $.ajax({
|
|
* url: "page.php",
|
|
* processData: false,
|
|
* data: xmlDocument,
|
|
* success: handleResponse
|
|
* });
|
|
* @desc Sends an xml document as data to the server. By setting the processData

* option to false, the automatic conversion of data to strings is prevented.
