CGI::Ajax - Export perl methods to javascript for AJAX

CGI::Ajax is a perl module to make it trivial to write AJAX scripts using Perl. The module is object-based Perl, and creating a link from a JavaScript event to your Perl code is as easy as defining the JavaScript function name to Perl subroutine name mapping.

• Can be used to link any Perl code to an HTML event, including fetching other URLs (using LWP, for example).
• Nestable, so an HTML event can start a chain of AJAX events (e.g. onClick="do_this(); now_that(); finally_this()").
• Can handle GET or POST.
• Not necessary to have your exported subroutines named in a specific way - you name them what you want.
• Very small overhead - lets you keep thinking Perl and not get bogged down.
• Active development community.
• Open-source library (Perl/Artistic license) by Brian Thomas.

HTML::Prototype - Generate HTML and Javascript for the Prototype library

HTML::Prototype contains some code generators for Prototype, the famous JavaScript OO library and the script.aculous extensions.

• Basically similiar to the Prototype helpers in Ruby Ajax Frameworks#Ruby On Rails.
• Open-source license (GPL and Artistic) by multiple contributors.

CGI::JSONRPC

CGI::JSONRPC links Perl objects to JavaScript objects, much like CGI::Ajax links Perl functions to JavaScript functions
