callback	| EventListenerOrEventListenerObject | null
options?	boolean | AddEventListenerOptions

Returns

void

Inherited from

---

append()

append(...nodes): void;

Inserts nodes after the last child of node, while replacing strings in nodes with equivalent Text nodes.

Throws a "HierarchyRequestError" DOMException if the constraints of the node tree are violated.

MDN Reference

Parameters

Parameter	Type
...nodes	(string | Node)[]

Returns

void

Inherited from

ParentNode.append

---

MDN Reference

Type Parameters

Type Parameter

Parameters

Parameter	Type
node	T

Returns

T

Inherited from

---

cloneNode()

Returns

boolean

Inherited from

Returns

boolean

Inherited from

Returns

boolean

Inherited from

Node.isEqualNode

Returns

boolean

Inherited from

Node.isSameNode

---

string | null

Inherited from

Node.lookupNamespaceURI

---
