title: jQuery: filter with multiple classes
body: <p>Is there a nice way to accomplish filtering selected elements down to a few classes? I know I could do them one at a time, but this just seemed to be something jQuery would allow.</p>
  
  <p>These are being served up with ajax, and I don't have access to define the actual html.</p>
  
  <pre><code>$('.val&gt;td').each(function () {
      $(this).filter('.price,.quantity,.remove').children().children().addClass('hidetaxfields');
  });
  </code></pre>
