Re: Notification of listbox selection change

Larry: You are making this more complicated than it needs to be. I simply have an index page that contains a div to hold the three selection controls (state/cit/zip). I use another php script (get.php) to present/populate the selection controls AND gather the data needed. The selection controls trigger the ajax routine like so: <select name="state" onchange="javascript:get(this.parentNode);"> The ajax routine sends the value selected to the get.php script which in-turn repopulates the selection controls. Repeat and rinse. tedd PS: Why use framesets? _______________ tedd sperling tedd@sperling.com On Jan 9, 2014, at 1:40 PM, Larry Martell <larry.martell@gmail.com> wrote: > On Thu, Jan 9, 2014 at 11:15 AM, Tedd Sperling <tedd@sperling.com> wrote: >> 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. > > Tedd- > > I understand how your code works.
