How to access the upper and lower element of a given element in jquery
<p>I have some div elements in a sequence, like :</p>

<pre><code> &lt;div id="a"&gt;&lt;/div&gt;
 &lt;div id="b"&gt;&lt;/div&gt;
 &lt;div id="c"&gt;&lt;/div&gt;
 &lt;div id="d"&gt;&lt;/div&gt;
</code></pre>

<p>Suppose i have id of 3rd position div which is <code>c</code>. Now i want to access the div element which placed just above and below ( in this case b &amp; d respectively ) of div whose id is <code>c</code>. How can i do this in jquery?</p>
