How can I ensure at least one checkbox is checked in a particular div?
<p>I have a <code>&lt;div class="answer" id="yesOptions"&gt;</code> and I need to check that at least 1 checkbox inside this particular  is checked.  If not, I need to return <code>alert('At least 1 checkbox must be checked from this div!');</code></p>

<p>How can I do this?  </p>
