The ParentNode interface contains methods that are particular to Node objects that can have children.

ParentNode is a raw interface and no object of this type can be created; it is implemented by Element, Document, and DocumentFragment objects.

Properties

ParentNode.children Somente leitura
Returns a live HTMLCollection containing all objects of type Element that are children of this ParentNode.
ParentNode.firstElementChild Somente leitura
Returns the Element that is the first child of this ParentNode, or null if there is none.
ParentNode.lastElementChild Somente leitura
Returns the Element that is the last child of this ParentNode, or null if there is none.
ParentNode.childElementCount Somente leitura

Methods

ParentNode.append()

ParentNode.prepend()
Inserts a set of Node objects or DOMString objects before the first child of the ParentNode. DOMString objects are inserted as equivalent Text nodes.
