Attach a function to be executed before an Ajax request is sent.

Note: Set up a basic Ajax load request, attach the event handler to the document. Now make an Ajax request using any jQuery method.

Sample solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-git.js"></script>
 <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
   <title> Attach a function to be executed before an Ajax request is sent.</title>
   </head>
   <body>
   <div class="jquery">jQuery: Click here</div>
   <div class="result"></div>
   <div class="log"></div>
 </body>
</html>

JavaScript Code :

$( document ).ajaxSend(function() {
  $( ".log" ).text( "Triggered ajaxSend handler." );
});

$( ".jquery" ).click(function() {
  $( ".result" ).load( "https://www.w3resource.com/jquery-exercises/jq-ajax-test.html" );
});

Used Methods :
