How to wrap text with A element

I have html code

  <td id="MyNode">开发者_Python百科;TextNode</td>

and would like to make it as

<td id="MyNode"><a href="http://www.domain.com">TextNode</a></td>

I have tried to use code below but what it does is add href attribute to TD element but I need to wrap text with A element.

 $('#MyNode').add('a').attr('href', 'http://www.domain.com/');

You can use .wrapInner():

$('#MyNode').wrapInner('<a href="http://www.domain.com/"/>');
