My problem is similar to this question but I need an answer in javascript. It is very simple to achieve this in jquery. I also debug the jquery file but it seems more confusing to me.

//if there is any ajax request
   document.getElementById("loader").style.display="block";
//on success:
   document.getElementById("loader").style.display="none";

can you show the code thats firing the ajax? although your link answer is using jquery, a native solution using a httpRequestObject would still use the callbacks for success – atmd Feb 06 '15 at 14:07
Actually we are submitting a form using iframe – Jitender Feb 06 '15 at 14:16
