title: Loop through all checkboxes that are inside a div tag
body: <p>I need to loop through all checkboxes that are inside a div tag with id #abc123</p>
  
  <p>How can I do this?</p>
  
  <pre><code>$("#abc123").foreach( ???? )
  </code></pre>
  
  <p><b>Update</b>
  my html row looks like:</p>
  
  <pre><code>&lt;tr&gt;
  &lt;td&gt;&lt;input .../&gt; &lt;/td&gt;
  &lt;td&gt;234&lt;/td&gt;
  
  &lt;/tr&gt;
  </code></pre>
  
  <p>I need to add the value of the <code>&lt;td&gt;</code> into the ID of the checkbox.</p>
  
  <p>Would I just get the parent, then ancestor it somehow?</p>
