Answer 1

As with the original poster, I was trying to

find the index of a given DOM node

but one that I had just use a click handler on, and only in relation to its siblings. I couldn't end up getting the above to work (because of noobness undoubtably, i tried subbing in 'this' for elem but it didn't work).

My solution was to use jquery and use:

var index = $(this).parent().children().index(this);

It works without having to specify the type of the element ie:'h1' or an id etc.
