How I can execute Javascript into Perl?

I don't know how I can execute an event of Javascript into a link in a program in Perl.
This event of JavaScript have executed a function that return a HTML page.
Anybody know how I can it?

Is it possible do it this?:
$datos=$datos.""<a>"";

What is bad in this code?

Thank you very much.

I don't think you will get help for this problem here, most of us are php developer
