Question

How can I show update progress while jquery ajax call is fetching data?

Answer 1

$.ajax({
          url :
          type : 

          beforeSend : function() {

             //Show some processing div
               $('#loader').show();
          },
          success : function() {
               /// Your code
          },

          complete : function() {
               //Hide the processing div
               $('#loader').hide();
          }
      });

You can create a div which you want to show it while processing.

You can show the div in the beforeSend function which gets called just before the request.
Hide it in the complete function which is called once the request is completed.
