Instance Method Details

#add_effect(element, event_type, effect_type) ⇒ Object

def add_effect(element, event_type, effect_type)
  script = shortcut_script(%{
    window.addEventListener("load", function(event) {
      $('#{element.get_attribute('id')}').#{event_type} = function(event) {
          Effect.#{effect_type}($(#{element.get_attribute('id')}));
          return false;
          };
      }
    );
  })
  @head.append(script)
end

#include_scriptaculous ⇒ Object

Includes the scriptaculous scripts in you page Note* it simply includes several script elements with relative paths to the scriptaculous script files, this method is really only useful if you have added this page to a Website object and have invoked the Website.include_scriptaculous_files method which will include the files when published. Unless you intend to create a javascript directory and include them yourself!
