Ques 3. Example on Progress Bar in Dojo framework.
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.
<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>
Progress Bar:
<body class="tundra">
<div dojoType="dijit.ProgressBar" style="width:800px"
jsId="jsProgress" id="downloadProgress"></div>
<input type="button" value="Start" onclick="download();" />
</body>
