Moving Data from Server to Client

[Mark Taylor]

Hi,
I'm creating a page that has several list boxes, let's call these A1, A2,
A3...A9. Depending on what is selected in A1, a list of items appears in
list box B1, A2 corresponds to B2 etc. I'll refer to the B list boxes as
Bx from here forward I don't want to have to go back to the server to retrieve
the item list for each Bx list box everytime a selection is made in it's
corresponding Ax list box because there are nine different A list boxes that
the user will select from when they use the page, that would get frustrating.
Here's a simple example using one of the nine list boxes, well call it Musical
Preferences:

ListBox A (Musical Preferences):
Jazz
Country
Alternative
HipHop

If I select Jazz in list box A I want ListBox B to display:

List Box B (Artists)
Miles Davis
John Coltrane
Charles Mingus
Thelonius Monk
Duke Ellington
etc

If I select Alternative in List Box A I want ListBox B to display:

List Box B (artists)
The Cure
Simple Minds
Depeche Mode
The Smiths
etc

Get the idea?

The only way I can think of to handle this is to set up some hidden text
areas so that the "lists" that will be placed in a B list box can be retrieved
via javascript when the user selects an item in an A list box. In the old
school, we would call this a kludge solution. Is there a better way?

Many Thanks

Mark

You can use WDDX to send the data as WDDX packets to the client side and populate
the list box (using Javascript) depending on the selection in A1.

What is WDDX?
How to use WDDX?
Can you give a sample?
Many Thanks.
