## .ajaxComplete( handler )Returns: jQuery

Description: Register a handler to be called when Ajax requests complete. This is an AjaxEvent.

- #### version added: 1.0.ajaxComplete( handler )

  - handler
    Type: Function( Event event, jqXHR jqXHR, PlainObject ajaxOptions )
    The function to be invoked.

Whenever an Ajax request completes, jQuery triggers the `ajaxComplete` event. Any and all handlers that have been registered with the `.ajaxComplete()` method are executed at this time.

To observe this method in action, set up a basic Ajax load request:

1 2 3 |
    <div class="trigger">Trigger</div><div class="result"></div><div class="log"></div>

Attach the event handler to the document:

1 2 3 |
    $( document ).ajaxComplete(function() {  $( ".log" ).text( "Triggered ajaxComplete handler." );});

Now, make an Ajax request using any jQuery method:

1 2 3 |
    $( ".trigger" ).click(function() {  $( ".result" ).load( "ajax/test.html" );});

When the user clicks the element with class `trigger` and the Ajax request completes, the log message is displayed.

All `ajaxComplete` handlers are invoked, regardless of what Ajax request was completed. If you must differentiate between the requests, use the parameters passed to the handler. Each time an `ajaxComplete` handler is executed, it is passed the event object, the `XMLHttpRequest` object, and the settings object that was used in the creation of the request. For example, you can restrict the callback to only handling events dealing with a particular URL:

1 2 3 4 5 6 |
    $( document ).ajaxComplete(function( event, xhr, settings ) {  if ( settings.url === "ajax/test.html" ) {    $( ".log" ).text( "Triggered ajaxComplete handler. The result is " +      xhr.responseText );  }});

Note: You can get the returned Ajax contents by looking at `xhr.responseText`.

### Additional Notes:

- As of jQuery 1.9, all the handlers for the jQuery global Ajax events, including those added with the `.ajaxComplete()` method, must be attached to `document`.
- If `$.ajax()` or `$.ajaxSetup()` is called with the `global` option set to `false`, the `.ajaxComplete()` method will not fire.

## Example:

Show a message when an Ajax request completes.

1 2 3 |
    $( document ).ajaxComplete(function( event, request, settings ) {  $( "#msg" ).append( "<li>Request Complete.</li>" );});
