Node: parentNode property
The read-only parentNode property of the Node interface
returns the parent of the specified node in the DOM tree.
Document and DocumentFragment nodes can never have a parent, so
parentNode will always return null.
It also returns null if the node has just been created
and is not yet attached to the tree. Node.parentElement on the other hand only returns Element nodes.
Value
A Node that is the parent of the current node. The parent of an element is
an Element node, a Document node, or a DocumentFragment node.
Example
Using parentNode
This example removes a node from the tree, unless it's not in the tree already.
js
if (node.parentNode) {
node.parentNode.removeChild(node);
}
