<html>
<head>
<title> My JSP 'test.jsp ' starting page </title>
<script type= "text/javascript ">
var mX;
var mY;
var flag=0;
function mousedown()
{
mX=event.clientX;
mY=event.clientY;
flag=1;
}
function mouseup()
{
flag=0;
}
function mousemove()
{
if(flag==0)return false;
var e=document.getElementById( 'aa ');
mXmov=event.clientX;
mYmov=event.clientY;
var w=e.offsetWidth;
e.style.width=w+(mXmov-mX);
}
</script>
<style type= "text/css ">
div{float:left;}
.aaCss{border:1px solid red;width:200px;height:100px;}
</style>
</head>
<body>
<div id= "body " onmouseup= "mouseup() ">
<div id= "aa " class= "aaCss "> AAAA </div>
<div onmousedown= "mousedown() " onmousemove= "mousemove() " id= "bb " style= "width:30px;border:1px solid gary; "> dragMe </div>
</div>
