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.
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;
