AJAX source

Hello Dear,

I have two files index.php and datatable.php. datatable.php has full html table which I want to change to datatable. when I put the code of datatable.php on index.ph it works fine. But it does not work when I try to load datatable.php with ajax call.

Please tell me that where should I add the javascript files for datatable ? on index.php or on datatables.php

I have tried in different ways but it is not working for me.

Thanks
