In this post I want to explain how to do live character or word count meter using Jquery. It is interesting and simple just ten lines of java script code. Use it and enrich your web applications with jquery.

Javascript code

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$("#contentbox").keyup(function()
{
var box=$(this).val();
var main = box.length *100;
var value= (main / 160);
var count= 160 - box.length;

if(box.length <= 160)
{
$('#count').html(count);
$('#bar').animate(
{
"width": value+'%',


}, 1);
}
else
{
alert('Full');
}
return false;
});

});
</script>
