Finding text and adding class to Parent

Finding text and adding class to Parent

Hi,

I want to find some text in an element and if-true, add class1 to it, if not add class2 to it.

eg.
<div id="myid">
<p>true</p>
</div>


So I want to search in "div#myid p" for "true" and if found, add class "class1" to the div, otherwise "class2".

Currently I'm using this code:

      $('td.result').each(function () {
         var t = $(this).text();
         t = t.replace(/FAIL/, '<span class="fail">FAIL</span>', /PASS/, '<span class="pass">PASS</span>');
         $(this).html(t);
      });


but its not exactly what I want because I want to add the class to parent.

Thanks in advance for your help.
