Larry:
You don't replace the entire page -- you fill-in the portion needed.
What you are missing here is DOM scripting.
The Ajax portion sends a GET request to a php script (get.php) that does all the db heavy work which in turn repopulates a "myspan" div, like so:
(index.php)
<div id="myspan"> <!-- start of myspan -->
<?php include("get.php"); ?>
</div> <!-- end of myspan -->
The get.php script has all the database stuff including the $_GET[] that brings in the state, city, and zip values.
Based upon what is provided, get.php script pulls the data from the db and populates the select controls with what is needed.
There is no refresh of the index page, but rather just an update of the "myspan" div via get.php.
