55b12015bcdecf19f771f5387bc9b14af54da374Dav Glass<p>First we need some HTML to work with.</p>
55b12015bcdecf19f771f5387bc9b14af54da374Dav Glass<ul id="demo">
55b12015bcdecf19f771f5387bc9b14af54da374Dav Glass <li>foo</li>
55b12015bcdecf19f771f5387bc9b14af54da374Dav Glass <li>bar</li>
e0b25dbc0322a078f384c45b48e5690f23d7eb15Dav Glass<h2>Adding Content</h2>
fc2d50365b169f761de7a15d7a4fe406b33fd403Dav Glass<p>Next we will add a handler to run when the event is fired. In our handler we will add content to the node.</p>
fc2d50365b169f761de7a15d7a4fe406b33fd403Dav Glass<p>Note that the event handler receives an event object with its <code>currentTarget</code> set to the current Node instance, and the actual node clicked as the <code>target</code>. The context of the handler is the NodeList instance, so <code>this</code> refers to our NodeList instance.</p>
fc2d50365b169f761de7a15d7a4fe406b33fd403Dav Glass<p>Note also that <code>prepend</code> inserts content as the <code>firstChild</code> of the Node instance, <code>append</code> inserts content as the <code>lastChild</code>, and <code>insert</code> places content before the specified node or childNode index.</p>

fc2d50365b169f761de7a15d7a4fe406b33fd403Dav Glass<p>We can assign our handler to all of the items by using the <code>all</code> method to get a <code>NodeList</code> instance and using the <code>on</code> method to subscribe to the event.</p>
