使用CDATA是否正确替换

Question

Am I using the CDATA correctly in code below because I am getting no error but getting warnings on start tag < starting here...

var $tbody = $('#qandatbl_onthefly > tbody');
var $tr = $("<![CDATA[<tr class='optionAndAnswer' align='center'>]]");
var $qid = $("<![CDATA[<td width='5%' class='qid'></td>]]").text(qnum);
var $options = $("<![CDATA[<td><table class='option'><tbody><tr><td class='opt'>1. Option Type:</td></tr></tbody></table></td>]]");
var $video = $("<![CDATA[<td width='17%' class='video'></td>]]");
var $endtr = $("<![CDATA[</tr>]]");
var $questionType = '';

Answer 1

You probably don't need the CDATA sections, but the ones you have are incomplete. The end is missing an additional >:

<![CDATA[ ... ]]>

<![CDATA[ <div>...</div> ]]>

The trailing angle bracket is missing in the examples you provided.

Answer 2

I think you dont need to use CDATA here. It's used when you get data from XML to recognize that it is the HTML content
