Listing 2. index.rhtml (Ajax Version)
    
        Sample HTML page
        <%= javascript_include_tag 'prototype' %>
    
    
        Headline
        
    <%= submit_to_remote "submit-button",
                    "Pig Latin it!",
            :url => { :action => "piglatin_sentence" },
            :submit => "fakeForm",
            :update => "headline" %>
    
]]>
We also have replaced our button with a call to the submit_to_remote
helper:
<%= submit_to_remote "submit-button",
                "Pig Latin it!",
        :url => { :action => "piglatin_sentence" },
        :submit => "fakeForm",
        :update => "headline" %>
