Although the answer is no, you could do this...

If you are calling the script from a form, include this:

# in the form
<form name="this_form" ...etc... >
<input type="hidden" name="use_js" value="">

# elsewhere (after form, or call as onLoad in body tag)
<script language="javascript">
document.this_form.use_js.value = "yes"
</script>
[download]

Then check for the value of the field use_js in your Perl script.

A similar result can be achieved through query string info if it's a link instead.
