Hear how ASP.NET AJAX 4.0 makes building pure client-side AJAX Web applications even easier, and watch us build an entire data-driven ASP.NET AJAX application from start to finish by taking advantage of only JavaScript, HTML pages, and Windows Communication Foundation (WCF) services. Also learn about new ASP.NET AJAX features including the DataView control, declarative templates, live client-side data binding, WCF, and REST integration.

21. for (var i=0;i < data.length;i++)
{
row = quot;<tr>quot;;
row += quot;<td>quot; + data[i].Title + quot;</td>quot;;
row += quot;<td>quot; + data[i].Director + quot;</td>quot;;
table += row;
}
$get(quot;movieBodyquot;).innerHTML = table;

<tbody id=quot;movieBodyquot; class=quot;sys-templatequot;>
<tr>
<td>{{ Title }}</td>
