+ <h1>The mouseenter, mouseleave, and hover Events</h1>
+ <div class="yui3-g">

+ <div id="main">
+ <div class="content"><div class="intro">
+ <p>The <code>event-mouseenter</code> module adds support for "mouseenter" and
+ "mouseleave" events that are often preferable alternatives to "mouseover"
+ and "mouseout".</p>
+
+ <p>The <code>event-hover</code> module adds support for a "hover" event that combines
+ subscriptions to each of these two events, taking two callback
+ functions, one for when the mouse enters the subscribed node, and another
+ for when it leaves the node.</p>
+</div>
+
+<h2 id="mouseover-and-mouseout-are-noisy"><code>mouseover</code> and <code>mouseout</code> are noisy</h2>
+
+<p>The <code>mouseover</code> and <code>mouseout</code> events bubble. That means with the following DOM structure...</p>
+
+<pre class="code prettyprint"><div id="hover-me">
+ <div class="header">
+ <button class="close">Close</button>
+ </div>
+ <div class="body">
+ ... more markup
+ </div>
+</div></pre>
+
+
+<p>...a <code>mouseover</code> subscription on <code>#hover-me</code> would be called three times when a user moved the mouse over the close button because</p>
+
+<ol>
+ <li>The user moused over #hover-me</li>
+ <li>The user moused over the <div> in #hover-me, and that <code>mouseover</code> event bubbled to #hover-me</li>
+ <li>The user moused over the close button, and that <code>mouseover</code> event bubbled to #hover-me</li>
+</ol>
+
+<p>Chances are, you don't care about any of these except the first. That's where <code>mouseenter</code> and <code>mouseleave</code> come in. They only fire when the <code>e.target</code> of the event is the node subscribed to. That means no noise.</p>
+
+<pre class="code prettyprint">YUI().use('event-mouseenter', 'transition', function (Y) {
+ var hoverMe = Y.one('#hover-me');
+
+ hoverMe.on('mouseenter', function () {
+ this.one('.header').transition('fadeIn');
+ });
+
+ hoverMe.on('mouseleave', function () {
+ this.one('.header').transition('fadeOut');
+ });
+});</pre>
+
+
+<p>Though these events work by essentially <em>not</em> bubbling, you can still delegate <code>mouseenter</code> and <code>mouseleave</code> using <code>node.delegate(...)</code>.</p>
+
+<pre class="code prettyprint">// The overHandler callback will be executed when any .hoverable
+// element is moused over.
+container.delegate('mouseenter', overHandler, '.hoverable');</pre>
+
+
+<h2 id="hover"><code>mouseenter</code> + <code>mouseleave</code> == <code>hover</code></h2>
+
+<p>It's common to pair <code>mouseenter</code> and <code>mouseleave</code> subscriptions (or
+<code>mouseover</code> and <code>mouseout</code> for the uninitiated) to create an effect that only
+lasts as long as the mouse is over an element. To make that easier, the
+<code>event-hover</code> module adds a <code>hover</code> event. It accepts a second callback and
+attaches the first to <code>mouseenter</code> and the second to <code>mouseleave</code>.</p>
+
+<pre class="code prettyprint">YUI().use('event-hover', 'transition', function (Y) {
+ function over() {
+ this.one('.header').transition('fadeIn');
+ }
+ function out() {
+ this.one('.header').transition('fadeOut');
+ }
+
+ // Two callbacks, `mouseenter` and `mouseleave`
+ Y.one('#hover-me').on('hover', over, out);
+});</pre>
+
+
+<p>If you need to override the default <code>this</code> object assignment or bind arguments to a <code>hover</code> subscription, just add those arguments after the second callback.</p>
+
+<p>Similarly, if you want to delegate the <code>hover</code> event, pass a CSS filter after the second callback.</p>
+
+<pre class="code prettyprint">// Default `this` to racerX
+mach5.on('hover', racerX.oilSlick, racerX.tireSpikes, racerX);
+
+// The delegate filter comes before the `this` override
+ruralTown.delegate('hover', ufo.scan, ufo.memoryWipe, '.person', ufo);</pre>
