      <p>This page describes the <code>ajaxComplete</code> event. For the deprecated <code>.ajaxComplete()</code> method, see <a href="/ajaxComplete-shorthand/"><code>.ajaxComplete()</code></a>.</p>
    </div>
    <p>Whenever an Ajax request completes, jQuery triggers the <code>ajaxComplete</code> event. Any and all registered <code>ajaxComplete</code> handlers are executed at this time.</p>
    <p>To observe this method in action, set up a basic Ajax load request:</p>
    <pre><code>
&lt;div class="trigger"&gt;Trigger&lt;/div&gt;
&lt;div class="result"&gt;&lt;/div&gt;
&lt;div class="log"&gt;&lt;/div&gt;
    </code></pre>
    <p>Attach the event handler to the document:</p>
    <pre><code>
$( document ).on( "ajaxComplete", function() {
  $( ".log" ).text( "Triggered ajaxComplete handler." );
} );
    </code></pre>
    <p>Now, make an Ajax request using any jQuery method:</p>
    <pre><code>
$( ".trigger" ).on( "click", function() {
  $( ".result" ).load( "ajax/test.html" );
} );
    </code></pre>
    <p>When the user clicks the element with class <code>trigger</code> and the Ajax request completes, the log message is displayed.</p>
    <p>All <code>ajaxComplete</code> 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 <code>ajaxComplete</code> handler is executed, it is passed the event object, the <code>XMLHttpRequest</code> 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:</p>
    <pre><code>
$( document ).on( "ajaxComplete", function( event, xhr, settings ) {
  if ( settings.url === "ajax/test.html" ) {
    $( ".log" ).text( "Triggered ajaxComplete handler. The result is " +
      xhr.responseText );
  }
} );
    </code></pre>
    <p><strong>Note:</strong> You can get the returned Ajax contents by looking at <code>xhr.responseText</code>.</p>
