Hello,

How can I tell (using either HTML or JSP) whether a user has their JavaScript disabled in the browser?

I'm developing an application and want to direct users to a different page depending upon that.

Many thanks.

Hi

Only the browser can tell if JavaScript is available and enabled. To send such information to the server you can do something like this :
Code: 
[gray]...[/gray]
<head>
<meta http-equiv="refresh" content="3;url=whatever.jsp?js=no">
<script type="text/javascript">
window.location.href='whatever.jsp?js=yes;
</script
</head>
[gray]...[/gray]
Although the preferred way is to simply do a JavaScript independent site, then enhance it with optional JavaScript code.

Some newer browsers, like IE7, have Meta refreshes disabled by default (at least in mine it was). I'd add in a link for the user to click if the redirect is unsuccessful.

So to expand on Feherke's example...
Code: 
<head>
<meta http-equiv="refresh" content="3;url=whatever.jsp?js=no">
<script type="text/javascript">
window.location.href='whatever.jsp?js=yes;
</script>
[b]<noscript>
<a href="whatever.jsp?js=no">Please visit our new site</a>
</noscript>[/b]
</head>
