title: jQuery selector based on child
body: <p>How would I, in the html below, select all divs where the closest child is not a span?</p>
  
  <pre><code>&lt;div&gt;test&lt;/div&gt; //should be selected
  &lt;div&gt;test2&lt;/div&gt; //should be selected
  &lt;div&gt;&lt;span&gt;test2&lt;span/&gt;&lt;/div&gt; //should not be selected
  </code></pre>
