jQuery.ajaxSetup()

jQuery.ajaxSetup( options )

Description: Set default values for future Ajax requests.

  • version added: 1.1jQuery.ajaxSetup( options )

    optionsA set of key/value pairs that configure the default Ajax request. All options are optional.

For details on the settings available for $.ajaxSetup(), see $.ajax().

All subsequent Ajax calls using any function will use the new settings, unless overridden by the individual calls, until the next invocation of $.ajaxSetup().

For example, the following sets a default for the url parameter before pinging the server repeatedly:

$.ajaxSetup({
  url: 'ping.php'
});

Now each time an Ajax request is made, the "ping.php" URL will be used automatically:

$.ajax({
  // url not set here; uses ping.php
  data: {'name': 'Dan'}
});

Note: Global callback functions should be set with their respective global Ajax event handler methods—.ajaxStart(), .ajaxStop(), .ajaxComplete(), .ajaxError(), .ajaxSuccess(), .ajaxSend()—rather than within the options object for $.ajaxSetup().

Example:

Sets the defaults for Ajax requests to the url "/xmlhttp/", disables global handlers and uses POST instead of GET. The following Ajax requests then sends some data without having to set anything else.

$.ajaxSetup({
   url: "/xmlhttp/",
   global: false,
   type: "POST"

 });
 $.ajax({ data: myData });
