Tech Info - W3C DOM-2 Overview

Our reference manual on the DOM-2 (currently the only one implemented by the Level 5 browsers). While the DOM is language independent all these pages use Javascript as the method of access (the API). W3C DOM Documents.

You need to understand how pages are constructed and how to navigate nodes before you dive into the details - or you will drown - fast!.

Interfaces

Its pretty scary when you need a map just to navigate the documentation but we did. But its a big spec..so.. The DOM consists of a number of separate specifications each of which describes one or more Interfaces each of which has a number of methods and attributes (properties). The following is a guide to documents/interfaces and the things they contain. The pages referenced document the usage and implementation (in various browsers) of a method or attribute and do not try to reproduce the existing - perfectly adequate - W3C documentation, which is always referenced on each page. Guide contains DOM-2 Core, DOM-2 HTML, DOM-2 Views, DOM-2 Traversal and Range, DOM-2 Style, DOM-2 CSS interfaces.
