[Javascript] Database and SQL

[billy.reisinger at gmail.com (Billy Reisinger)]

Javascript is event-driven.  The "change" event fires when the user  
changes a drop down (select) value.  You can use Ajax to pass data  
between the client and server, so you could build the GET or POST  
query from the change event (fired by the drop down), hit the url  
with Ajax, use whatever server side technology you want to do the db  
query, and return the content to the client.   You'll then need to  
drop the returned content onto the page using Javascript.
