The Radio button helper also has an onclick option so you can remote
call a function when ever they click the button, or execute some
javaScript. I have done this many times in my apps, for exmaple with
gender:
<% func1 = remote_function( :update => '', :url => {
:action => 'gender_female', :id => @user.id},
:with => "'select=' + escape(value)" ) %>
<% func2 = remote_function( :update => '', :url => {
:action => 'gender_male', :id=> @user.id},
:with => "'select=' + escape(value)" ) %>
<span id = "female">Male:
<%= radio_button_tag( :gender, :male,
@user.gender.to_s == "Male" ? true : false,
:onclick => func2 )%></span>
<span id = "male">Female:
<%= radio_button_tag( :gender, :female,
@user.gender.to_s == "Female" ? true : false,
:onclick => func1 )%></span>
