If it is a posting to a form, then have some input fields, usually
'hidden' for this purpose that the JavaScript sets their value before
submition of the form.

<script type="text/javascript">
function someJavaScriptFunction(){
var f=document.forms[0];
...
f.toBeSet.value="Some Value Derived by JavaScript";
...
return true;
}
</script>

....

<form action="myPerlScript.pl" onsubmit="someJavaScriptFunction()>
<input type="hidden" name="toBeSet">
....
</form>

Take care,
