Javascript vars into Perl Script

[audiopro]

I need to pass a var from a Javascript into a perl script but how?
I have been trying the FAQ's for a few days but cannot acess them.

Easiest way is to have a hidden form variable you can access and set from JS that gets posted to Perl with the rest of the form.

== Belongs in Javascript forum really
yea, and if you are computing them on the fly in your javascript, you can use the DOM to define form values dynamically. Something like:

<form name="sweet" action="whatever">
<input type="hidden" name="foo" value="" />
<input type="button" value="Click" onClick='document.sweet.foo.value = "bar";' />
</form>
==

Then, as icrf indicated, just retrieve that value as a normal CGI parameter.

I've actually become kind of a fan of document.getElementById() as it seems to be pretty well supported (and form names in .NET don't mean so much as they used to). But still, that's a stylistic JS issue.

Just be sure to check whatever you set in JS server-side in Perl as well. I've run into JS-calculated totals being taken as real totals before, a big no-no.

I wasn't sure which forum to post into but hoped that someone would be able to help. A Javascript function creates a hidden var which is posted to the script in the normal way. One of those cases where the answer is simple when you know it.
