Hello,

How do I detect if a visitor's browser has enabled JavaScript support?

I searched Google, and found someone used the following,

Code:

<head>
.......
<noscript>
<meta http-equiv="refresh" content="0; URL=url_to_non_js_page">
</noscript>
</head>

but my script can not pass w3.org's HTML validator, it doesn't seem to be the right place to place the above code.

thank you.

Put the <noscript> tags in the body section, works for me that way...

eg:

Code:

<body>
<noscript>
<meta http-equiv="refresh" content="0; URL=url_to_non_js_page">
</noscript>
.............
</body>

You can display text in javascript that say, YOU HAVE JAVASCRIPT ENABLED!!

Why would it not be the right place to put a META tag? Or do you mean the <noscript> tag?

Personally, I would rather do it the other way around if you are not sure the browser does not support javascript. I would write something like this into a non JS enabled version of my page

<head>
<script>
window.location.href = "location_of_js_enabled_page"
</script>
</head>

This way, if JS is enabled, the page automatically redirects to a JS enabled page or just fails to the normal web page.
