is it possible to make real time progress/percentage bar in jquery -

-

below code simple jquery progress bar. there way update progress value (that 67 rite now)dynamically on ajaxstart , reach value 100 on ajaxstop()? 

  <head><script src="http://code.jquery.com/jquery-1.9.1.js"></script>     <script src="http://code.jquery.com/ui/1.10.2/jquery-ui.js"></script>     <link rel="stylesheet" href="/resources/demos/style.css" />        <script>$(function() {         $( "#progressbar" ).progressbar({         **value: 67**         });         });         </script>     </head>        <body>     <div id="progressbar"></div>     </body>

if targetting html5 browsers only, try whats decribed here:jquery ajax progress in html5

the traditional way go show spinning gif, instead of loader.

ajax request wont long in of cases & hence effort in trying same lost.

however not uncommon progress bar shown. problem is, older browsers did not share info js & developers left using hacks like,

  • using of flash. flash plugin keep track of amount of data uploaded & hence tell javascript.

  • a method of approximating time works in cases.

  • the choice remains ping server continuously know how transfer took place.
