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 / 145);
var count= 145 - box.length;

if(box.length <= 145)
{
$('#count').html(count);
$('#bar').animate(
{
"width": value+'%',
}, 1);

{
alert(' Full ');
}
return false;
