DIALOG HELPER

Dialog is a simple script for displaying styled dialog windows in browsers.  It builds on the excellent Prototype and 
Scriptaculous libraries.  The look and feel is CSS driven, and it's easy to create your own custom dialogs.  
Be sure to include dialog.js and add the appropriate styles.

If install.rb did not copy the latest dialog.js, use the rake task:

  rake update_dialog_helper

Here are some examples from the docs:

  <%= create_dialog(:confirm, 
        :message => 'Are you sure?', 
        :okay_test => 'Sure!', 
        :on_okay => "function() { alert('whoa'); }") %>
 
  new Dialog.Confirm({message:'Are you sure?', okayTest:'Sure!', onOkay:function() { alert('whoa'); }});

  <%= link_to_dialog('Open', {:confirm, 
        :message => 'Are you sure?', 
        :on_okay => "function() { alert('whoa'); }"},
       {:title => 'Click to open dialog'}) %>
  
  <a href="#" title="Click to open dialog"
    onclick="new Dialog.Confirm({message:'Are you sure?', onOkay:function() { alert('whoa'); }});; return false;">
    Open
  </a>
