jQuery beautiful Animated Progress bar Plugin

The dynamic animated progressbar. I think you already know this jQuery widget – Progressbar. By default – this is static widget without any animation. Today we will expand possibilities of that plugin – we will make it – dynamic. And also will issue our result as a new jQuery plugin.

Step 1. HTML

Here are all html of my demo

index.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="#">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="pbar"></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>

As you can see – I prepared 3 progressbars. Each progressbar will have own behaviour (using own properties).

Also, make attention to linked jQuery libraries and styles. How I prepared this? Very easy, goto here, select UI Core and single widget – Progressbar, then – just Download result. You will get package with all necessary libraries (jquery-1.6.2.min.js + jquery-ui-1.8.16.custom.min.js + jquery-ui-1.8.16.custom.css + related images).

Step 2. CSS

Here are our CSS styles.

css/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.

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.
