observer with group of radio buttons
Hi,
My code looks like this
<%get_date_ranges().each{|arr|%>
<input type="radio"
id="criteria[<%=count%>][date_range]"
name="criteria[<%=count%>][date_range]"
value="<%=arr[0]%>" />
<%=arr[1]%>
</br>
<%}%>
<%= observe_field("criteria[#{count}][date_range]",
:url => { :action => :date_range, :count =>
count,:type_id => type_id, :report_key => report_key },
:frequency => 3,
:with => "''type_id=''+value")
%>
I have a group of radio buttons and i want the observer to fire an
action when any radio button is checked.
But the observer is not working. Can someone suggest what could be the
possible reason for it not to work.
Neha

Re: observer with group of radio buttons
But if i have a group of radio buttons, they should have the same id so that they form a group Also if i give them different ids then on what will my observer field act?

I think that you either need an observer for each button, or if they are in a form you can use observe_form which will trigger when any element in the form changes. -- Rick DeNatale My blog on Ruby http://talklikeaduck.denhaven2.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: observer with group of radio buttons
If i give them all different ids, then will it be possible to have a observe_field on the name of the radio buttons as the number of buttons is quite high and i dont want to have a separate observer for each button as that will make the code quite cumbersome. And my form is being built up dynamically so i cant have observe_form also.
