This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
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.
Syntax
flag = nodeIterator.pointerBeforeReferenceNode;
Example
var nodeIterator = document.createNodeIterator(
document.body,
NodeFilter.SHOW_ELEMENT,
{ acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },
false
);
flag = nodeIterator.pointerBeforeReferenceNode;
