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

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.
