NodeIterator: detach() method
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
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
js
detach()
Parameters
None.
Return value
None (undefined
).
Examples
js
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
