From what I am reading it seems like you are looking for an ajax call to send data to another script and receive the response. If you are using jquery you can read more about it here: http://api.jquery.com/jquery.ajax/. In the event you are not using jquery you may want to take a look at this post: How to make an AJAX call without jQuery?.
