in reply to CGI::AJAX onclick

I think we need to see more of your code. CGI::Ajax shouldn't define the Javascript function display() unless you have told it to handle that function in your constructor.

Update: I would also make sure that your JS attribute values have proper quotes around them, e.g. onclick="...". And, FWIW, this modification of the CGI::Ajax example program works for me - is this what you want to do?

#!/usr/bin/perl use strict; use CGI; # or any other CGI:: form handler/decoder use CGI::Ajax; my $cgi = new CGI; my $pjx = new CGI::Ajax( 'exported_func' => \&perl_func ); print $pjx->build_html( $cgi, \&Show_HTML); sub perl_func { my $input = shift; # do something with $input my $output = $input . " was the input!"; return( $output ); } sub Show_HTML { my $html = <<EOHTML; <HTML> <HEAD> <SCRIPT> function display() { alert("I am in display") }; </SCRIPT> </HEAD> <BODY> Enter something: <input type="text" name="val1" id="val1" onkeyup="exported_func( ['val1'], ['resultdiv'] );display(this) +"> <button type=button onclick="display(this)">Click me!</button> <br> <div id="resultdiv"></div> </BODY> </HTML> EOHTML return $html; }

    So what I am doing is creating a link that when clicked loads a perl function, display, then through the same click passes a variable to a sub in perl. What this is for is when a user clicks a title of a post it expands then will query a sql server to display the content under the expanded title. So, the code you posted I would have to remove the text attribute and make that a href then have an onclick event assocate with it to load display, and to pass the variable to exported_func
