JQuery and Perl to display dynamic results on drop down selection

[ReFuSeR]

I'm currently using Perl CGI to display some internal billing pages at work. I'm using JQuery as well to add a little 'spunk' to it if you will.I'm looking to generate/display HTML based on drop down selection by the user. Now, I can handle this part no problem. I'm generating table rows/table data on click based on the selection made by the user. I want to retrieve and display values stored in the database for the corresponding data im displaying on button click, and without refreshing the page of course.Can someone point me in the right direction? Thanks in advance.
