Dependent select boxes
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
type.
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.
Thanks,
Brian

Take a look at the jguru faq for dynamic select box. You should generate
javascript arrays dynamically and use them in the functions, I hope it
will
be helpful
