How do I use Ajax with jQuery in Perl?

If I call this function directly it works fine, yet if I call it from Javascript using an ajax call it wont work correctly.

I found out the reason for this, it w开发者_如何学编程as cause I was using $(document).ready(function ..) where I should call the functions directly after the ajax returns the results.

At minimum, your Perl script needs to output the following kind of text before any other output:

Content-Type: text/html

Note that there must be an empty line after the Content-Type line.

If you fail to do this, the server will not send the text to the JavaScript. Typically it would trip the line

alert('There was a problem with the request.');

in your JavaScript. If you examine the value of the variable .status, it should be equal to 500, an error code which indicates your script failed.

So confusing, your perl code just outputs html without any headers (like content-type). Your javascript doesn't seem to use jQuery, and none of the referred IDs appear anywhere in your example.

Were you looking to use load something like: $('#view_span').load('filename_ajax.cgi');?
Or perhaps:

$('#view_span').load(
  'filename_ajax.cgi',
  {'target': escape(encodeURI('get_section'))},
  alertViewResult);

Although it's a bit under-documented (at least for someone who isn't already intimately familiar with jQuery itself), have you taken a look at JQuery on CPAN?
