HTML:
<div id="container">
<div id="bar">
</div>
</div>
CSS:
#container {
width: 20px;
height: 150px;
position: relative;
}
#bar {
width: 100%;
height: 100%;
background-color: red;
position: absolute;
bottom: 0px;
}
JS:
function Bar(element) {
this.barEl = element;
this.progress = 100;
}
Bar.prototype.setProgress = function (p) {
if(p >= 0) {
this.progress = p;
this.barEl.style.height = this.progress + "%";
}
}
var barObj = new Bar(document.getElementById('bar'));
setInterval(function () {
barObj.setProgress(barObj.progress - 10);
}, 1000);
This code from jsfiddle http://jsfiddle.net/Mp7R3/ is not working when I copy paste the code but it is working fine on jsfiddle .maybe I have some onLoad problem but I dont know how to solve it . I tried $(document).ready(function() but it didnt help .

Be sure you don't forget the script for calling jQuery in the <head>
of your code:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
You can also try to place the code at the bottom of your code so it's can run only if the full page is loaded.
I also write below the simplest page to make this code work (normally you should separate HTML, CSS and JS), so you can compare it with your own:
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<title>- That's Work!!! -</title>
<style>
#container {
width: 20px;
height: 150px;
position: relative;
}
#bar {
width: 100%;
height: 100%;
background-color: red;
position: absolute;
bottom: 0px;
}
</style>
</head>
<body>
<div id="container">
<div id="bar">
</div>
</div>
</body>
<script type="text/javascript">
function Bar(element) {
this.barEl = element;
this.progress = 100;
}
Bar.prototype.setProgress = function (p) {
if(p >= 0) {
this.progress = p;
this.barEl.style.height = this.progress + "%";
}
}
var barObj = new Bar(document.getElementById('bar'));
setInterval(function () {
barObj.setProgress(barObj.progress - 10);
}, 1000);
</script>
</html>
I hope it will help you!
