Subject Dependent select boxes
Date Tue, 22 Jul 2003 10:45:05 GMT
Hi all,
I have an application that uses dependent select boxes, 
ie, by picking one item in a select box, then the contents 
of the next one will be decided.
This is used as a way to navigate a tree structure. I know 
that this is a common way of representing this structure 
The problem is: currently for every onChange in the select
box, I go back to the server to populate the contents of the 
next select box. 
Now I know this is bad. I have the entire tree in memory, but 
I'm really weak on javascript. I want to move to a javascript 
solution where I populate javascript arrays and the whole tree 
can be navigated without going back to the server.
Can someone please give me a hand/advice? 
First off, how do I populate javascript variables from bean variables.
