title: Finding appropriate parent with jQuery
body: <p>Given a DOM element how do I find its nearest parent with a given css class?</p>
  
  <pre><code>$(".editButton").click(function() {
     (magic container selector goes here).addClass("editing");
  });
  </code></pre>
  
  <p>I don't want to use lots or $(...).parent().parent() since I don't want to be bound to a particular dom structure.</p>
