Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The NodeIterator.detach() method is a no-op, kept for backward compatibility only.
Originally, it detached the NodeIterator from the set over which it iterates, releasing any resources used by the set and setting the iterator's state to INVALID. Once this method had been called, calls to other methods on NodeIterator would raise the INVALID_STATE_ERR exception.
Syntax
nodeIterator.detach();
Example
var nodeIterator = document.createNodeIterator(
document.body,
NodeFilter.SHOW_ELEMENT,
{ acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },
false
);
nodeIterator.detach(); // detaches the iterator
nodeIterator.nextNode(); // throws an INVALID_STATE_ERR exception
