Definetly not the best way. I would send you to this page, but it's
outdated, unfortunately: http://codex.wordpress.org/AJAX_in_Plugins

Basically, instead of calling a script directly, you should do this:

For logged-in users:

add_action('wp_ajax_my_action', 'my_ajax_handler');

For the public:

add_action('wp_ajax_nopriv_my_action', 'my_ajax_handler');


The js should look something like this:

jQuery.post(<?php echo admin_url('admin_ajax.php'); ?>, {action:
'my_action', foo: 'bar'});


And the php:

function my_ajax_handler() {
  var_dump($_POST);
}


That's about it.
