<h1>Example: Handling Menu Click Events (YUI Library) <em>[<a href="index.html">Examples Home</a>]</em></h1>
|
||||
<p>This example demonstrates how to register a "click" event handler for a MenuItem instance. All of the events for YUI Menu are instances of <a href="http://developer.yahoo.com/yui/event/#customevent">YAHOO.util.CustomEvent</a>. To register a listener for an event, use the event's "subscribe" method passing a pointer to your handler as the first argument. You can pass an argument to your event handler(s) as an additional second argument to the "subscribe" method.</p>
|
||||
<p id="clicknote"><em>Note:</em> By default clicking outside of a menu will hide it. Additionally, menu items without a submenu or a URL to navigate will hide their parent menu when clicked. Click the "Show Menu" button below to make the menu visible if it is hidden.</p>
|
||||
<button id="menutoggle">Show Menu</button>
