title: add class and keep checking rest of document
body: <p>I am trying to add a class to a bold element only if the bold element does not already have the class specified.  Can someone please tell me what I am missing.  It stops running after it finds one that fails instead of checking each.</p>
  
  <pre><code> if ($("font[size='3'] b").hasClass('dont_run')) {}
   else {$("font[size='3'] b").addClass('barcode_needed')
   };
  </code></pre>
