observe_field w/check_box (how do you capture unchecked event?)
Hi: Does observe_field work w/check_box?
When a checkbox is checked, all works. When it is unchecked, I get
"undefined" for params[:option].
more info on what I''m using:
-----------------------
my check_box method produces this:
<input type="checkbox" value="1"
name="option[R]" id="option_R"/>
<input type="hidden" value="0"
name="option[R]"/>
my observe_field is:
<%= observe_field "option_#{option}",
:update => ''commandLine'',
:url => {:action =>
''updateCommand''},
:with => ''option'',
:on => ''click'' %>

For one of my applications the observer passes "1" when it is checked and "undefined" when it isn''t. "undefined" should probably be "0", but you can still tell whether or not it is checked. -Jonathan.

I think you''d be safer testing to see... if params[:option] != "1" then.... where "1" is the value of the ''value'' attribute. Cause some web browser might just decide to start returning false or nil or 0 instead of ''undefined'' so you''re test for ''undefined'' would then fail... Just a thought.> > -Jonathan. > > On 10/18/06, Tate Hansen <tate-yND1hqhjdFzIa13z/PHSgg@public.gmane.org> wrote: >> >> >> Hi: Does observe_field work w/check_box? >> >> When a checkbox is checked, all works.

Re: observe_field w/check_box (how do you capture unchecked event?)
I forgot to mention I have lots of checkboxes for this view, so I can''t determine which box the uncheck was triggered from because of the ''undefined''.
