It doesn't work that way a'tall; by the time the Javascript is executing
(in the browser), your perl script (running on the server) has exited.

You might want to look into using server authentication; the user must
identify themselves before your CGI is ever run. Then, in your script, you
can simply do:
   $username = $ENV{REMOTE_USER};

This is a useful link about Web-based login:

(not really anything to do with Perl, mind you.)
