title: Searching, recursively, the children of all divs of a certain class
body: <pre><code>&lt;div class="testClass"&gt;
      &lt;div&gt;
          &lt;select name="specialName123"&gt;
          &lt;/select&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  
  &lt;div class="testClass"&gt;
      &lt;div&gt;
          &lt;span id="someSpan"&gt;
              &lt;select name="specialName123"&gt;
              &lt;/select&gt;
          &lt;/span&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How do I select the two above divs on my page based on the fact that they have the class "testClass" and have a select that has "123" in it's name?</p>
  
  <p>I understand I can find all selects like so <code>$('select[name*="123"]')</code>, and I can use <code>$(".testClass")</code> to select the appropriate divs. But how do I put these together in the way I need to?</p>
