title: jquery find next element without attribute
body: <p>I have a large form that I want to navigate through by pressing enter instead of tab. I have a simple script which worked fine until I added some disabled fields into the mix. How can I skip the fields that have the attribute of disabled?</p>
  
  <p>I've tried using a loop but I cannot get it to skip the two disabled fields together and focus to the next one, as it seems to stay on the field before the disabled ones.</p>
  
  <p>Failing that, is there a way to replace the enter keyCode of 13 with the one for tab? I've tried a few solutions here but none of them seem to work</p>
  
  <pre><code>$('input').on('keydown', function (e) {
      if (e.keyCode == 13) {
          e.preventDefault();
          $('input')[$('input').index(this)+1].focus();
      }
  });
  </code></pre>
