Hi, I have observers for a group of radio buttons, an observe_field for each radio button (I think its not possible to have one observe_field for a group of radio buttons). Now, the problem is that when I click on one radio button, all the observers get trigerred, so the method which the observe_field calls gets the wrong result. I just want that method to get the radio button that is clicked, which seems quite obvious, no? Any idea how to do this? Help would be greatly appreciated! Thanks, Aditya -- Posted via http://www.ruby-forum.com/.

You can test the value of the button group by: $(''common-radio-button-id'').value == ''foo'' That should at least tell you whats selected. -- Posted via http://www.ruby-forum.com/.
Hello Aditya,
Without seeing your code, I have to ask this; the radio buttons all
share the same name (obviously, otherwise they wouldn''t be a radio
buttons group ;) but, have you given each a unique id ? giving a unique
id will then mean you can tie an ''observe_field'' onto each one
in turn.
The only other thought I have that could (perhaps) be done, is
having some :with javascript that grabs the ''selected'' from
the radio
buttons and then passes this over to the observe_field function. That
may mean you could only have one observe_field for all of them.. but..
totally untested and jst a theory ;)
Let us know how it all turns out :)
Regards
Stef

Thanks for the reply. Unfortunately the radio buttons have different
id''s (though the same name). The ''value'' is appended
to the id, which
makes the id''s different for all the buttons. Which is why I need to
have a different observer for each button (since the observer takes the
id name).
Moreover, $(''common-radio-button-id'').value doesn''t
work. I get a parse
error, so probably that syntax is incorrect. Also, I don''t know if the
radio_button has a "value" method. I don''t see anything about
it in the
Rails API.
Any other ideas?

I believe (1) simply because as I said in the reply above, the ''value'' is appended to the id, which makes the id''s different for all the buttons. Which means that a single observe_field won''t work for a group of button. Actually I think I made a little mistake by saying that "when I click on one radio button, all the observers get trigerred". In fact, as one would expect, the observers that get triggered are the ones for the radio button that gets deselcted and the one that gets selected. -- Posted via http://www.ruby-forum.com/.
Hi Aditya, Can you tell me how to write observers with radio buttons. I am new to rails. Please send me code snippets if possible. Thanks, Nitin.

Hi Nitin, Please post the code you''re having trouble with. Or Google ''rails observe_field radio_button''.
