This example demonstrates how to listen for DOM-related events. Interaction with the Menu will result in event information being output to the console. Please note: Disabled MenuItem instances do not fire DOM events. This is demonstrated with the MenuItem named "MenuItem 2."
Note: By default clicking outside of a Menu instance will hide it. Additionally, MenuItem instances without a submenu or a URL to navigate to will hide their parent Menu instance when clicked. Click the "Show Menu" button below to make the Menu instance visible if it is hidden.
All of the events for Menu and MenuItem (including DOM-based events such as
"mouseover" or "click") are implemented as instances of
YAHOO.util.CustomEvent). Please note: To
listen for DOM-based events always use the provided Custom Event-based interface
rather than attaching handlers directly to a Menu's DOM elements.
Add event listeners through the
subscribe method. The following
example demonstrates how to subscribe to the "show" and "hide" events:
