Thanks Chris! I was able to get it working!
You're right about the Ajax not being needed, I'm just so used to
thinking that anything that "pops up" is ajax, even though it doesn't
need to be a server request. Sorry about that.
Two issues I'm having with this implementation though:
First, if I go to edit the form, I can see the '2' is selected but the
guest_name field is hidden until I select a different number of tickets
(I guess this activates/reloads the javascript). I even tried doing an
if statement in the div: <div id="guest_name"<%= " style='hidden'" if
[email protected] == '2' %>> which works (I can see this from the page
source). However, the div is ALWAYS visible, until I select a different
number of tickets and it acvtivates/reloads the javascript. Any ideas on
how to get this to work?
Second, I ended up using a table structure for the form, wrapping the
DIV around the <TR> doesn't work (the guest_name field is always
visible). I'm guessing this is a table structure issue so I need to take
a more in depth look.
Thanks again for the code Chris! It was extremely helpful.
