5) insertAfter()

As far as I know, Jeremy Keith sort of came up with this idea even though one would have thought this too would be a DOM core method. But just like getElementsByClass, it isn’t. So rather than pulling the function straight out of the book, I’ll leave that up to you to buy it yourself. Instead I’ve pulled this simple method from public domain:

insertAfter() on public domain

function insertAfter(parent, node, referenceNode) {

	parent.insertBefore(node, referenceNode.nextSibling);

}
