All properties except for url are optional. A default can be set for any option with $.ajaxSetup(). See jQuery.ajax( settings ) for a complete list of all settings. Type will automatically be set to POST. This is a shorthand Ajax function, which is equivalent to: 1 2 3 4 5 6 7 $.ajax({ type: "POST", url: url, data: data, success: success, dataType: dataType}); The success callback function is passed the returned data, which will be an XML root element or a text string depending on the MIME type of the response. It is also passed the text status of the response. As of jQuery 1.5, the success callback function is also passed a "jqXHR" object (in jQuery 1.4, it was passed the XMLHttpRequest object). Most implementations will specify a success handler: 1 2 3 $.post( "ajax/test.html", function( data ) { $( ".result" ).html( data );}); This example fetches the requested HTML snippet and inserts it on the page. Pages fetched with POST are never cached, so the cache and ifModified options in jQuery.ajaxSetup() have no effect on the
