How to add an id attribute to a html tag with a certain class using jQuery?
<p>I have a link with a class of <code>special</code> and I want to add an id attribute to it.</p>

<p>Only one element in my document will have this class at any one time (I may remove and add a new one at some point).</p>

<p>How would I add an id attribute to the element to change it from this:</p>

<pre><code>&lt;div class="special"&gt;
</code></pre>

<p>to this:</p>

<pre><code>&lt;div id="special-12345" class="special"&gt;
</code></pre>
