jquery selector when a child element satisfies a criteria
<p>I have the following code:</p>

<pre><code>&lt;a href="#" class="btn"&gt;
&lt;i class="icon-thumbs-up"&gt;&lt;/i&gt;
&lt;/a&gt;
</code></pre>

<p>I need to write a jQuery selector for:</p>

<p>Anytime an anchor is clicked that has a tag inside of it of class='icon-thumbs-up', then...</p>
