+<p>Clicking in the yellow box will give hello world feedback.
+Clicking on the first link will take you to the YUI website; clicking on the
+second link, which has the same <code>href</code> attribute, will display
+a message instead, and not navigate to a new page.</p>
+
+<p>Event Utility is used here to do two things:</p>
+
+<ol>
+	<li>Attach the <code>click</code> event handler to the yellow box;</li>
+	<li>Attach an event handler to the second <code>&lt;a&gt;</code>
+    element that uses <code>preventDefault()</code> to prevent the link,
+    when clicked, from navigating to a new page. </li>

+
+<h2>Reacting to the <code>click</code> event</h2>
+
+<p>To illustrate event handling syntax, we'll create a <code>&lt;div&gt;</code> and
+give some feedback when that <code>&lt;div&gt;</code> is clicked.</p>
+
+<pre class="code prettyprint">&#x2F;&#x2F; Create a YUI instance and load the &#x27;node&#x27; module
+YUI().use(&#x27;node&#x27;, function (Y) {
+
+    &#x2F;&#x2F; A function that gives hello world feedback:
+    var helloWorld = function(e) {
+        e.target.setHTML(&quot;&lt;p&gt;Hello World!&lt;&#x2F;p&gt;&quot;);
+        Y.one(&#x27;#container&#x27;).addClass(&#x27;hello&#x27;);
+    }
+
+    ...</pre>
+
+
+<p>We now use the Node's <code>on</code> method to attach our
+<code>helloWorld</code> function as a handler for the <code>click</code> event.
+
+<pre class="code prettyprint">&#x2F;&#x2F; Point to the container div with the CSS selector
+var node = Y.one(&#x27;#container&#x27;);
+
+node.on(&quot;click&quot;, helloWorld);</pre>
+
+
+<p>Almost all event handling begins with a premise just this simple: we have an
+element to which something might happen (eg, it might be clicked) and, when
+that <em>does</em> happen, we want to do something (eg,
+<code>helloWorld</code>).</p>
+
+<h2 id="prevent">Preventing event behavior</h2>
+
+<p>In some cases, you may want to replace the default behavior of an event.
+For example, let's say you have two links on the page:</p>
+
+<pre class="code prettyprint">&lt;p&gt;&lt;a href=&quot;http:&#x2F;&#x2F;yuilibrary.com&#x2F;&quot; id=&quot;firstA&quot;&gt;The YUI Library. (Link navigates away from page.)&lt;&#x2F;a&gt;&lt;&#x2F;p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http:&#x2F;&#x2F;yuilibrary.com&#x2F;&quot; id=&quot;secondA&quot;&gt;The YUI Library. (Link&#x27;s default behavior is suppressed.)&lt;&#x2F;a&gt;&lt;&#x2F;p&gt;</pre>
+
+
+<p>Let's say that when the second link is clicked, instead of navigating away
+from the current page, you want to display a message.
+The event object passed to your event handler is a facade &mdash; not
+the actual browser event object.
+This facade supports the <code>preventDefault</code> method for cancelling
+inherent browser behavior such as anchor links loading a new page.</p>
+
+<pre class="code prettyprint">&#x2F;&#x2F; A function that stops the browser from navigating away
+&#x2F;&#x2F; from the page, and instead displays a message.
+var interceptLink = function(e) {
+    e.preventDefault();
+    Y.one(&#x27;.message&#x27;).setStyle(&#x27;visibility&#x27;, &#x27;visible&#x27;);
+}
+
+&#x2F;&#x2F; subscribe our interceptLink function to the second anchor
+Y.one(&#x27;#secondA&#x27;).on(&quot;click&quot;, interceptLink);</pre>
+
+
+<h2 id="fullcode">Full Code Listing</h2>
+<pre class="code prettyprint">&lt;div id=&quot;demo&quot;&gt;
