NodeIterator: detach() method

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

detach()

Parameters

None.

Return value

None (undefined).

Examples

const nodeIterator = document.createNodeIterator(
  document.body,
  NodeFilter.SHOW_ELEMENT,
  {
    acceptNode(node) {
      return NodeFilter.FILTER_ACCEPT;
    },
  },
);
nodeIterator.detach(); // detaches the iterator

nodeIterator.nextNode(); // throws an INVALID_STATE_ERR exception
