Can an .htaccess detect if the browser has a javascript enable or disable?

Question

Can an htaccess could detect a browser if it's javascript enable or disabled and write a certain condition if javascript is disbled?

Like this

if(js)

DirectoryIndex ../locnfo/jsenable.php else

DirectoryIndex ../locnfo/jsdisable.php

Answer 1

No, an .htaccess file cannot do such a thing : an .htaccess file configures how Apache (server) behaves -- while Javascript is something that's on the client-side (browser).

If you want to detect whether Javascript is enabled or not, you'll have to do that on the client-side.
About that, here are a couple of questions / answers that might help :

• How to detect if JavaScript is disabled?
• How to detect if a user had javascript disabled?

Answer 2

This has to be done on the client side, it cannot be detected elsewhere. The best thing I would suggest is to have something like

<script type="text/javascript">
   document.write('<script type="text/javascript" src="path/to/js"></script>');
</script>

so the file is only included if Javascript is enabled.
