Is an Element an instance of a Node in HTML?

I presume Attributes are also Nodes and that "the Elements" is the set of Nodes that can be defined using the angle-bracket syntax?

回答1:

Yes it is a Node, according to the MDN documentation for HTMLElement :

Inherits properties from its parents Node, and its own parent, EventTarget, and implements those of ParentNode, ChildNode, NonDocumentTypeChildNode, and Animatable.

If that's a bit hard to find in text, MDN also provides an "Inheritance section" in the left sidebar.

回答2:

Properties

Inherits properties from its parents Node, and its own parent, EventTarget, and implements those of ParentNode, ChildNode, NonDocumentTypeChildNode, and Animatable.
