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.
ParentNode.children Read only
HTMLCollection containing all objects of type Element that are children of this ParentNode.ParentNode.firstElementChild Read only
Element that is the first child of this ParentNode, or null if there is none.ParentNode.lastElementChild Read only
Element that is the last child of this ParentNode, or null if there is none.ParentNode.childElementCount Read only
unsigned long giving the amount of children that the object has.ParentNode.append()
Node objects or DOMString objects after the last child of the ParentNode. DOMString objects are inserted as equivalent Text nodes.ParentNode.prepend()
Node objects or DOMString objects before the first child of the ParentNode. DOMString objects are inserted as equivalent Text nodes.| Specification | Status | Comment |
|---|---|---|
| DOM The definition of 'ParentNode.firstElementChild' in that specification. | Living Standard | Splitted the ElementTraversal interface in ChildNode and ParentNode. The firstElementChild, lastElementChild, and childElementCount properties are now defined on the latter.The Document and DocumentFragment implemented the new interfaces.Added the children property.Added the append() and prepend() methods. |
| Element Traversal Specification The definition of 'ElementTraversal' in that specification. | Recommendation | Added the initial definition of its properties to the ElementTraversal pure interface and use it on Element. |
