Hi,
here is the situation: I have an "export to excel button" on click of which i open a window that calls a servlet in an iframe tag.
in the javascript part, i have a method that creates a progress bar, and runs untill some value in session is made true..
The problem is, the session value is not changing as i am not refreshing my page.. :P..
can somebody suggest a way to develop a progress bar while the servlet generates the excel and renders it to the client??see my jsp code below
[HTML]<script type="text/javascript">
function progress()
{
var flg='<%=session .getValue("flag ")%>';
var t;
if(flg == null)
{
alert("inside if");
intWidth = parseInt(docume nt.getElementBy Id("statusBar") .style.width) + 1;
if(intWidth <= 400){
document.getEle mentById("statu sBar").style.wi dth = intWidth+"px";
}else{
document.getEle mentById("statu sBar").style.wi dth = 0;
}
t=setTimeout("p rogress()",1000 );
}
else if(flg=="stop")
{
alert("inside else");
alert(document. getElementById( "message1").val ue);
alert(document. getElementById( "message2").val ue);
document.getEle mentById("messa ge1").value = 'Finished...';
document.getEle mentById("messa ge2").value = '';
clearTimeout(t) ;
<%session.remov eAttribute("fla g");%>
}
}
</script>
</head>
<body>
<div id="displayed" >

<div id="hidden" style="display: none;">
<p id="message1" style="font-size: 15pt; font-family: sans-serif; color:#fd6700; background:#fff ;">

document.getEle mentById('hidde n').style.displ ay='';
document.getEle mentById('displ ayed').style.di splay='none';
