Today i m going to create a dynamic animated progressbar using jquery, Below is the demo for the animated progress bar.
index.html
Step 1: HTML
Here are all html of my demoindex.html
<!DOCTYPE html>
<html lang="en">
<head>
<link href="css/jquery-ui-1.8.16.custom.css" rel="stylesheet" type="text/css"/>
<link href="css/main.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="js/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.8.16.custom.min.js"></script>
<script type="text/javascript" src="js/script.js"></script>
<title>Animated jQuery progressbar | Script tutorials</title>
</head>
<body>
<div class="example">
<h3><a href="http://www.script-tutorials.com/animated-jquery-progressbar/">Animated jQuery progressbar | Script Tutorials</a></h3>
<div id="progress1">
<div class="percent"></div>
<div class="pbar"></div>
<div class="elapsed"></div>
</div>
<hr />
<div id="progress2">
<div class="percent"></div>
<div class="elapsed"></div>
</div>
<hr />
<div id="progress3">
<div class="percent"></div>
<div class="pbar"></div>
<div class="elapsed"></div>
</div>
</div>
</body>
</html>
Step 2. CSS
Here are our CSS styles.
main.css
body{background:#eee;font-family:Verdana, Helvetica, Arial, sans-serif;margin:0;padding:0}.example{background:#FFF;width:650px;font-size:80%;border:1px #000 solid;margin:20px auto;padding:15px;position:relative;-moz-border-radius: 3px;-webkit-border-radius: 3px}h3 {text-align:center}.pbar .ui-progressbar-value {display:block !important}.pbar {overflow: hidden}.percent {position:relative;text-align: right;}.elapsed {position:relative;text-align: right;}
Step 3. JS
In this JS we will write expanded plugin for jQuery with our new progressbar.
script.js
script.js
$(document).ready(function(){
jQuery.fn.anim_progressbar = function (aOptions) {
// def values
var iCms = 1000;
var iMms = 60 * iCms;
var iHms = 3600 * iCms;
var iDms = 24 * 3600 * iCms;
// def options
var aDefOpts = {
start: new Date(), // now
finish: new Date().setTime(new Date().getTime() + 60 * iCms), // now + 60 sec
interval: 100
}
var aOpts = jQuery.extend(aDefOpts, aOptions);
var vPb = this;
// each progress bar
return this.each(
function() {
var iDuration = aOpts.finish - aOpts.start;
// calling original progressbar
$(vPb).children('.pbar').progressbar();
// looping process
var vInterval = setInterval(
function(){
var iLeftMs = aOpts.finish - new Date(); // left time in MS
var iElapsedMs = new Date() - aOpts.start, // elapsed time in MS
iDays = parseInt(iLeftMs / iDms), // elapsed days
iHours = parseInt((iLeftMs - (iDays * iDms)) / iHms), // elapsed hours
iMin = parseInt((iLeftMs - (iDays * iDms) - (iHours * iHms)) / iMms), // elapsed minutes
iSec = parseInt((iLeftMs - (iDays * iDms) - (iMin * iMms) - (iHours * iHms)) / iCms), // elapsed seconds
iPerc = (iElapsedMs > 0) ? iElapsedMs / iDuration * 100 : 0; // percentages
// display current positions and progress
$(vPb).children('.percent').html('<b>'+iPerc.toFixed(1)+'%</b>');
$(vPb).children('.elapsed').html(iDays+' days '+iHours+'h:'+iMin+'m:'+iSec+'s</b>');
$(vPb).children('.pbar').children('.ui-progressbar-value').css('width', iPerc+'%');
// in case of Finish
if (iPerc >= 100) {
clearInterval(vInterval);
$(vPb).children('.percent').html('<b>100%</b>');
$(vPb).children('.elapsed').html('Finished');
}
} ,aOpts.interval
);
}
);
}
// default mode
$('#progress1').anim_progressbar();
// from second #5 till 15
var iNow = new Date().setTime(new Date().getTime() + 5 * 1000); // now plus 5 secs
var iEnd = new Date().setTime(new Date().getTime() + 15 * 1000); // now plus 15 secs
$('#progress2').anim_progressbar({start: iNow, finish: iEnd, interval: 100});
// we will just set interval of updating to 1 sec
$('#progress3').anim_progressbar({interval: 1000});
});
In first half you can see our new jQuery plugin – anim_progressbar, in second – several examples of initializations with different params. We will pass to constructor next params: start (date of starting), finish (date of finishing) and interval (interval of updating progressbar). So you can set here not only different time, but even different days (dates)
