title: How to know which element in body triggered AJAX request in jQuery
body: <p>I'm working on an app and trying to use the Facebook behavior for an AJAX request. In Facebook you get a nice loading image next to the icon which triggers the AJAX request. Well, it's pretty simple to implement if you have 1-2 elements in the page.</p>
  
  <p>I want to make it generic and would like that whenever any element triggers an AJAX request, I want to show a small GIF next to it. For this, I thought the AjaxSend event of jQuery would be good enough, but alas it doesn't give me a handle of the object which triggered the AJAX call. I would like to know if it is possible via some method of jQuery to know which element triggered the AJAX call and also to get the same handle when the AJAX call is completed.</p>
  
  <p>If you feel my approach to the problem is not correct, I would love to hear your suggestions.</p>
