Simple jQuery code snippet to set loading image using ajaxSetup() so that every time an AJAX request is sent a loading image is displayed and when it returns the loading image is hidden. The reason for including the same code for complete and success is that the .load() function seems to ignore (or override) the complete function.

Demo

The Code

$.ajaxSetup({
 beforeSend: function() {
    $('#general-ajax-load ').fadeIn();
 },
 complete: function() {
    $('#general-ajax-load ').fadeOut();
 }
 success: function() {
    $('#general-ajax-load ').fadeOut();
 }
});
