In the broader sense, lostjimmy's response is entirely correct. You need to use AJAX to do what you describe and he explained what goes on behind the scenes when you do so.

To actually make all this happen, take a look at the CGI::Ajax module on CPAN. It provides a very easy way to set up an interface for Javascript events to trigger Perl functions and display the results.
