Showing Busy loading Indicator during an AJAX Request using jQuery

Last modified on by Karthikeyan K

In this post I am going to discuss how to show a busy loading indicator during Ajax call.

Recently, when I was developing one cool project, I needed a progress indicator to show the user that something was happening in the background.

Previously I had written simple jQuery preloader for websites and it was working very well in all browsers

I thought this post will be very useful to improve their website user experience.

Busy Loading Indicator using jQuery

jQuery Code to Ajax Indicator Start

The below function ajaxindicatorstart() is to show the busy loading indicator while ajax request starts anywhere in the body. Parameter is used to show the text below loading image.

	function ajaxindicatorstart(text)
if(jQuery('body').find('#resultLoading').attr('id') != 'resultLoading'){
jQuery('body').append('<div id="resultLoading" style="display:none"><div><img src="ajax-loader.gif"><div>'+text+'</div></div><div class="bg"></div></div>');


jQuery('#resultLoading .bg').css({

'width': '250px',
'text-align': 'center',
'position': 'fixed',


jQuery('#resultLoading .bg').height('100%');
jQuery('body').css('cursor', 'wait');

jQuery Code to Ajax Indicator Stop

The below function ajaxindicatorstop() is used to hide the busy loading indicator while ajax request stops anywhere in the body.

	function ajaxindicatorstop()
jQuery('#resultLoading .bg').height('100%');
jQuery('body').css('cursor', 'default');

The below jQuery code will trigger the ajax start & stop function in the document. More details available at:

  jQuery(document).ajaxStart(function () {
//show ajax indicator
ajaxindicatorstart('loading data.. please wait..');
}).ajaxStop(function () {
//hide ajax indicator

If you want to do an specific ajax request without having the loading indicator, you can do it like this by setting global:false

global: false,
// ajax stuff

I hope you will like this tutorial. You can use this code in your live projects.

    Thanks Buddy Worked perfectly !!! My suggestion is why can’t add css styling in the global.css or somewhere for the div instead of adding through jQuery as per the coding conventions. Any way stuff helped a lot for me 🙂
