CW3C DOM Reference

Because JavaScript is primarily used to program the browser and add behavior to web pages, it’s only natural to include a reference to the W3C DOM.

The following pages list the objects made available by the W3C DOM.

DOM CORE OBJECTS

This section describes and lists objects defined by the DOM standards—starting with the lowest level of DOM objects. All objects are in alphabetical order.

Low-Level DOM Objects

The DOM specification describes the Node, NodeList, and NamedNodeMap objects. These are the lowest-level objects in the DOM, and are the primary building blocks of higher-level objects.

Node

Defined in DOM Level 1, the Node object is the primary data type for the entire DOM. All objects in the DOM inherit from Node. There are 12 different types of Node objects; each type has an associated integer value. The following tables list the Node object’s type values, properties, and methods.

Node Types

ELEMENT_NODE 1 Level 1 Element
ATTRIBUTE_NODE 2 Level 1 Attr
