observe_field and radio_button

I had a group of radio buttons that I wanted to trigger some action when one of the button is selected. I setup an observe_field for each radio button but it didn't work. You can't specify observe_field to monitor a group of radio buttons. It would only monitor the first button. Actually, let me clarify that statement. It would work the first time a user click on the button but then subsequence click would not register as something has changed. Apparently, it keeps the last value and when the radio button is selected again, the last value and the current value is the same. That result in a no change. I ended up using onclick with remote_function to trigger the change event.

This is what I had and it doesn't work.

<%= radio_button_tag 'ship_method', 'pickup', :checked => true -%> Pickup

<%= radio_button_tag 'ship_method', 'deliver' -%> Deliver

<%= observe_field 'ship_method_pickup',
:url => { :controller => 'checkout', :action => 'ship_method_select' },
:on => 'click', :with => 'method' -%>

<%= observe_field 'ship_method_deliver',
:url => { :controller => 'checkout', :action => 'ship_method_select' },
:on => 'click', :with => 'method' -%>

This is what I ended up with

<input type="radio" name='ship_method' id='ship_method_pickup'
 checked="checked" value="pickup"
onclick="<%=
remote_function(
:url => {:controller => 'checkout', :action => 'ship_method_select', :method => 'pickup'}
)-%>" />

How to pass a class or id to link_to_remote

This does seem like a really simple thing now that I figured out how to do it.

<%= link_to_remote 'Name',
{:url => {:controller => 'some_controller', :action =>'some_action', :id => some_id}},{ :class => 'some_class' }-%>

If you want to specify a fall back url for href instead of the default # you can put that in the html_options part also.

<%= link_to_remote 'Name',
{:url => {:controller => 'some_controller', :action => 'some_action', :id => some_id}},
{:class => 'some_class', :href => url_for({:controller => 'some_controller', :action => 'some_action', :id => some_id}) }-%>
