finding out the number in a set of elements
<p>How can I establish, on click, which order an element is within a set, so if I click the third element in a set, I get a three?</p>

<p>Here is a jsfiddle example -> <a href="http://jsfiddle.net/vtt3d/" rel="nofollow">http://jsfiddle.net/vtt3d/</a></p>
