<div id="demo">Click me</div><script>// Create a new YUI sandbox and load the "node" module.YUI().use('node','datatable', function (Y) {var demo = Y.one('#demo'); demo.on('click', function (e) { demo.set('text', 'You clicked me!'); });});</script>

class="highlight"><em>Profit</em></li>');

<em>World</em>!</h1>");

// Append new markup inside a NodebodyNode.append("<p>This is the end, beautiful friend,

the end.</p>");

Nodelist var doneTasks = Y.all('#tasklist .completed');

// NodeLists host most Node methods for simple iterative operationsdoneTasks.removeClass('highlight');

// or call each() to do more work on each NodedoneTasks.each(function (taskNode) { taskNode.transition({ opacity: 0 }, function () { …….. });});

EventYUI().use('event', function (Y) { // Step 1. Capture a button node

var button = Y.one("#readygo");
