Hi,
I have a form with two lists. One is populated with many options
while the second is populated with only a single item. When the
first drop-down list is changed, I call a PHP script sing AJAX to
populate the second list. I also need to perform another task when
the second list is changed but it seems not to work.
I think this is because even though my AJAX script populates the
second drop-down list using pure PHP code, the second drop-down
isn't aware of it. I've tries adding JavaScript code in the AJAX
route to add options to the list but it's not working.
Does anyone have an example of how to do this?
Don:
As I understand your problem, there's no need to let the server-side
know anything until after the user has selected their choice from the
drop-downs. You can do everything client-side via javascript and not
use AJAX at all.
Here's an example of populating drop-downs using just javascript:

It's a simple matter to put in a submit button and pass the user's
selections on to a waiting php script.
I think using Ajax here is over complicating your problem.
Cheers,
tedd
