# Thanks to Sebastien Gruhier for his Prototype Window Class (http://prototype-window.xilinus.com/)
# Samples: <a href="http://pwc-helper.xurdeonrails.com" >http://pwc-helper.xurdeonrails.com</a>
#Quick use:
#Reference this helper in your rails applicaction adding -> helper :prototype_window_class in your application.rb
#You must include in the template header the prototype window class javascripts and the .css theme you want to use.
#This code in your template might be enough:
# <%= stylesheet_link_tag 'default' %> (or theme you wanna use)
# <%= stylesheet_link_tag 'alert' %>
# <%= javascript_include_tag :defaults %>
# <%= javascript_include_tag 'window'%>
class JsCode < String # for JavaScript Code Handling purpose
end
