jquery: Finding the last child from a selector
<p>For example, I've got a selector here</p>

<pre><code>var $myNeeds = $('.history');
</code></pre>

<p>This selector would have multiple divs inside, and now I want to get the last child from it, how to do this?</p>

<p>I tried <code>$myNeeds.last()</code>, this won't work!</p>
