Is it possible to find the parent of an element then navigate the DOM?
<p>When using jQuery how does one return to navigating the DOM. For example, if I found the parent of an item like this:</p>

<pre><code>$(this).parent()
</code></pre>

<p>How can you find something with an id of 'foobar'.
I've tried:</p>

<pre><code>$(this).parent().$('foobar').addClass('hello')
</code></pre>

<p>But I get the message:</p>

<pre>Uncaught TypeError: Object [object Object] has no method '$'</pre>
