jQuery: Get tag inside element with class
<pre><code>&lt;div id="yes"&gt;
  &lt;div class="wrapper"&gt;
    &lt;something&gt;...&lt;/else&gt;
    &lt;p&gt;foobar&lt;/p&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>I want to get the p-tag to append a classname</p>

<pre><code>$("div.wrapper", "#yes").addClass("newClassName");
</code></pre>

<p>But where to add the "p"?</p>
