Radio buttons and AJAX

Rails
1

Hi,

Here is what I would like:

2 radio buttons:

“yes” and
“no”

There will be 2 containers:

Yes stuff
No stuff

What I want is whenever the “yes” radio button is selected, on the “yes”
div should be made visible.

When the “no” radio button is clicked, I want only the “no” div visible.

I’ve had many shots, but nothing works.

I was using RJS, because more than one update is required. I have to
make one appear and one disappear, which is 2 calls. This way you can
toggle back and forth.

The problem is calling the template. I couldn’t find a way to do
something like this that worked:

<%= radio_button “project”, “yes_or_no”, “1”, :onclick => :url { :action
=> “show_yes” } %>

Then I tried:

<%=
observe_field(‘project_yes_or_no_1’,
:url => { :action => “show_yes”})
%>

This only works some of the time, and only once. Once the template is
called it never works again (if I click back and forth between the radio
buttons)

I’m sure the RJS template works ebcause I tried it with a
link_to_remote.

I’m out of ideas…

Thanks in advance.

Have a great day,
Brian

Does the “yes” stuff and “no” stuff really require another server
roundtrip?
It might just be easier to serve them both and use Javascript to turn
them
on and off as appropriate. You don’t even have to set up observers if
you
don’t want to. A simple onclick= should get you to your js function.

Hi Steve,

Thanks for the tip.

The reason I havn’t just used JS was I was hoping to use
script.aculo.us, but you can’t use more than one effect for every
onclick can you?

Or should I just generate a Javascript function that runs both of these.

Look into queuing effects. You can use multiple effects, but I haven’t
done
it.
