perl & Asynchronous Javascript

[InfiniteLoop]

Greetings Monks

 

Im in the process of using asynchronous javascript (current jargon: ajax) with my CGI::Application based application.

• Should I code my CGI's in a different way for this ? Do I have to expose the interface(s) via xml-rpc ?
• Are there any CPAN modules for this ?

All you need to do is return an valid XML document. You can also set content-type to text/xml which will automatically force it into an XML object when received by your Javascript.

I've only used HTML::Prototype (via Catalyst::Plugin::Prototype) a little, but it was a very pleasant experience.

You can do the same with CGI::Application through the CGI::Application::Plugin::HTMLPrototype plugin. It has a couple examples to show you how to use it as well.

You don't have to change anything you do in CGI::Application when you use the prototype library. All AJAX calls are just standard GET or POST requests to your application, and the only difference is that usually you only return a small piece of HTML that gets placed into the existing page somewhere instead of returning a full HTML page.

Greetings InfiniteLoop,

As I mention here and here, I'm a big fan of JSON (JavaScript Object Notation) and the JSON.pm module from CPAN. When used with CGI::Application, you just return the JSON-created string out of the subroutine that's setup by setup instead of your normal template content. It's crazy-simple.

Here's some sample code...
