title: Add class to multiple cached jquery elements
body: <p>With jQuery is it possible to add a class to multiple cached elements at the same time. I know i could do the following:</p>
  
  <pre><code>cachedElement1 = $('#div1');
  cachedElement2 = $('#div2');
  
  cachedElement1.addClass('someclass');
  cachedElement2.addClass('someclass');
  </code></pre>
  
  <p>But is there a short way of doing it.  So something like the below which doesn't actually work.</p>
  
  <pre><code>$(cachedElement1,cachedElement2).addClass('someclass');
  </code></pre>
  
  <p>Thanks</p>
