title: Jquery hasClass for multiple classes
body: <p>I am having,</p>
  
  <pre><code>&lt;tr valign="top"&gt;
      &lt;th class="chkCol fixed"&gt;..checkbox..&lt;/th&gt;
      &lt;th class="fixed"&gt;..head..&lt;/th&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>Now in Jquery I am calling a function like,</p>
  
  <pre><code>if($(this).hasClass("fixed")){
     ....
  }
  </code></pre>
  
  <p>If I call <code>$(this).hasClass("fixed")</code>, then I need to get only head not checkbox and that is working perfect in Jquery 1.4.2 but now I updated to jquery 1.6.1.
  Now I am getting checkbox inside if condition.</p>
  
  <p>Please Help,</p>
  
  <p>Thanks in advance</p>
