# By Jorge Díaz - <a href="http://xurde.info" >http://xurde.info</a>
# email: <a href="mailto:jorgedf@gmail.com">jorgedf@gmail.com</a>
# 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

module PrototypeWindowClassHelper

#support methods

def params_for_javascript(params) #options_for_javascript doesn't works fine

'{' + params.map {|k, v| "#{k}: #{
case v
when Hash then params_for_javascript( v )
when JsCode then v
# when Array then...
when String then "'#{v}'"
else v   #Isn't neither Hash or String
end }"}.sort.join(', ') + '}'
end
