Progress Bar : The progress bar is a GUI (Graphical User Interface) that gives dynamic feedback on the progress of a long-running operation. The progress bar can be updated by calling the JavaScript functions. Which works best for long-running JavaScript operations or a series of JavaScript XHR calls to the server. Progress bar performs to multiple types of works such as: download or upload any files and representation of the progress in a percent format.

Here is the code of Program:

<html>
<head>
<title>Progress Bar Demo</title>

  <style type="text/css">
  @import "../resources/dojo.css";
  @import "../dijit/themes/tundra/tundra.css";
  
  </style>

  <script type="text/javascript" src="dojo.xd.js" 
  djConfig="parseOnLoad: true"></script>

  <script type="text/javascript">
  dojo.require("dijit.ProgressBar");
  dojo.require("dojo.parser");
 
  function download(){
  // Split up bar into 5% segments
  numParts = Math.floor(100/5);
  jsProgress.update({ maximum: numParts, progress:0 });
  for (var i=0; i<=numParts; i++){
  // This plays update({progress:0}) at 1nn milliseconds,
  // update({progress:1}) at 2nn milliseconds, etc.
  setTimeout("jsProgress.update({ progress: " + i + " })",(i+1)*100 + 
Math.floor(Math.random()*100));
  
  }
  }
 </script>
</head>

How to do a real progress bar?

Hey, Thank you for this tuto, But I think it does pretty much nothing, because a real progress bar has to show the progress of an action, and what seems that you're doing here is like an animation, not a progress bar that for instance shows the loading progress of a page.
