This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The NodeIterator.pointerBeforeReferenceNode read-only property returns a Boolean flag that indicates whether the NodeFilter is anchored before (if this value is true) or after (if this value is false) the anchor node indicated by the NodeIterator.referenceNode property.


flag = nodeIterator.pointerBeforeReferenceNode;


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