Ajax XMLHttpRequest with Perl GET

[Angus]

Hello

I want to get an Ajax example working with a Perl script.

I have this at the moment but nothing seems to get sent to the server

self.xmlHttpReq.open('GET', 'http://myurl.com/example.pl?name=lisa', true);
self.send();

But as I say nothing gets sent.

I then have a:
self.xmlHttpReq.onreadystatechange = function()

Which handles responses. Should this work? In a real script what would I
send for the open and what for the send?

Why not have a look at one of the zillions of examples, tutorials, etc.
about AJAX [1]? All you need to adapt is your URI when calling open().

In addition to the links that Gregor has posted, you may find the
CGI::Ajax Perl module (which comes with examples) useful. It hides
most of the javascript though; the Mozilla and Microsoft links are
better resources if you really want to understand the XMLHttpRequest
(XHR) object.
