Hi monks,

As i did before. i try to play around with datatables from
http://www.datatables.net/release-datatables/examples/server_side/server_side.html

so i picked up a easy sample from the site to practice. I have copy a js to local server. and amke a minor change to server_side.html i just change
"sAjaxSource": "scripts/server_processing.php"
to
"sAjaxSource": "scripts/server_processing.cgi"

So what i should do is make server_processing.cgi to reutrn a valid json response to javascripts. your could get php's response from http://www.datatables.net/release-datatables/examples/server_side/scripts/server_processing.php and it also published on the site as well. http://www.datatables.net/release-datatables/examples/server_side/server_side.html

here is how i did in perl

#!c:/perl/bin/perl.exe 
##   test
use CGI;
use strict;
use warnings;

my $cgi = CGI->new;
print $cgi->header( 'application/json' );
print $json;
[download]

However when i run the page server_side.html on local server. it returns error
The error message is :
Datatables varning (table id = 'example'): requested unknow parameter '1' from the data source for row 0

I wonder what is the problem? it seems above perl scirpt did not return a right jason response to datatables? Any ideas?

Thanks in advance.
