<div id="noScripts"> Scripting is disabled </div>
<script type="text/javascript">
document.getElementById("noScripts").style.display="none";
</script>
<noscript>In fact, your browser is so old it does not even know what a
script is!</noscript>

Obviously, there is nothing you can do with this info:
you can't run a script to detect that scripts are disabled.
That is, you can not have "if (scriptsDisabled) {...}"

The code above would tell me that IE 4 & 5, Netscape 4.x and Opera 6.x all
have scripting disabled when that may not be true.

Something like the following is usually recommended:

<head>
<script type="text/javascript">
window.location.href = 'jsEnabledPage.html';
// or window.location.replace('jsEnabledPage.html');
</script>
</head>
<body>
Scripting is disabled
</body>
