The TreeWalker.previousSibling()
method moves the current Node
to its previous sibling, if any, and returns the found sibling. If there is no such node, return null
and the current node is not changed.
Syntax
node = treeWalker.previousSibling();
Example
var treeWalker = document.createTreeWalker(
document.body,
NodeFilter.SHOW_ELEMENT,
{ acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },
false
);
var node = treeWalker.previousSibling(); // returns null as there is no previous sibiling
