title: "Any" boolean function in jquery
body: <p>Is there any <strong>easy</strong> way to check if any elements in a jquery selector fulfill a condition? For instance, to check if any textboxes in a form are empty (kind of pseudo, not real jquery):</p>
  
  <pre><code>$('input.tb').any(val().length == 0);
  </code></pre>
  
  <p>Note: I know it could be done with a helper method, just curious if it was possible in one statement.</p>
