Check the Browser compatibility table carefully before using this in production.

flag = nodeIterator.pointerBeforeReferenceNode;

Example

var nodeIterator = document.createNodeIterator(
    document.body,
    NodeFilter.SHOW_ELEMENT,
    { acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },
    false
);
flag = nodeIterator.pointerBeforeReferenceNode;
