Jquery getting a child class of a selector retrieved using .prev
<pre><code>back = $("#contactus_"+id).prev();
</code></pre>

<p>I'm probably asking a simple question, but how do I get at .up_btn class from the id above?</p>

<p>normally to target this class i would do $("#contactus_"+id+" .up_btn") however in this instance I can't place the class name in there like that since I want the previous sibling's child.</p>

<p>Thanks</p>
