ghosh123 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monk,
I have used a popup_menu in my cgi perl code as below. But I do not know how to do a func

print $cgi->popup_menu(-name => 'rpt', -values => ['a','b'], -onChange => editValue() );

This onChange => editValue() is not working in the above popup_menu. Please let me know how can I make a function call everytime I select an item from the drop-down. The function should be passed that selected value .

    Are you aware of how HTTP, HTML and CGI interact?

    You will either need Javascript on the client side, or make the user submit the new parameters by clicking a button.
