This snippet contains a small script that would show you how to scroll any page title or you can say marquee to Title using JavaScript.
<script>
var scrl = " My ASP.NET Application "; // Title you want
function marqtitle() {
scrl = scrl.substring(1, scrl.length) + scrl.substring(0, 1);
document.title = scrl;
setTimeout("marqtitle()", 500);
}
</script>
That's it done. Now you just need to call marqtitle() method onload event of body.
<body onload="marqtitle()">
Done, You'll now able to see that your page title would be scrolling.
