Rails - Sep 2005 - Silly AJAX question (read : newbie alert) - checkbox vs link_to_remote

Hello.

I have a form that needs to be different depending on if the customer
being created is a person or organization. I''m just prototyping the
application right now, so most of the actual methods etc. aren''t
implemented yet.

What I wish to do is have two radio-buttons with Person/Organization -
and an AJAX call to instantly show the right form based on the radio
button you click.

I can''t figure out how to do it. Right now I have two stupid, ugly
link_to_remote links like so:

*************


<% @heading = "New Customer" %>
<%= javascript_include_tag "prototype" %>
  <%= error_messages_for ''customer'' %>
  <p><%= link_to_remote ("Customer is a person", 
	 		 :update => ''formdiv'',
                         :url => { :action => :form_person } ) %>
  </p>
  <p><%= link_to_remote ("Customer is an organization",
                         :update => ''formdiv'',
                         :url => { :action => :form_organization } ) %>
  </p>
  <div id="formdiv">&nbsp</div>


*************

the actions just do render (:layout => none) and hence load the
corresponding .rhtml view file into the div. That works just fine.

My question then - how can I run the ajax calls based on the (as of yet
non-existant) radio buttons? And preferrably move the link_to_remote
calls into a controller method to clean up the code somewhat?

I think that best way to do this is to use observe_field or
observer_form methods. Look to documentation on them.
