title: jQuery: Selecting by class and input type
body: <p>I would like to select a set of elements that are both of a certain input type (say, a checkbox) and have a certain class using jQuery.  However, when I try the following:</p>
  
  <pre><code> $("input:checkbox .myClass")
  </code></pre>
  
  <p>I don't get any items returned.  How can I accomplish this in jQuery?</p>
