Review of the Document Object Model

At first glance, people look at web pages as though they are pages in a book, consisting of static text and images. It soon becomes apparent that there are things with which you can interact, such as links and forms. In fact, pages aren't static "paintings," but are actually built up out of parts.

Let's take a "real world" example of a radio, which is made up of parts:

• Radio
• Volume dial
• Tuner dial
• Power Supply
• Speaker

Each of these parts has properties which describe it, and methods, or things that it can do. For example:

Object	Properties	Methods
Volume dial	minimum setting maximum setting	Set volume to a specified level
Power Supply	voltage	Turn on Turn off
