The TreeWalker.parentNode()
method moves the current Node
to the first visible ancestor node in the document order, and returns the found node. If no such node exists, or if it is above the TreeWalker
's root node, returns null
and the current node is not changed.
node = treeWalker.parentNode();
var treeWalker = document.createTreeWalker( document.body, NodeFilter.SHOW_ELEMENT, { acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } }, false ); var node = treeWalker.parentNode(); // returns null as there is no parent
