Lesson 3 Review
We covered four main topics today: windows, frames, the Document Object Model, and Object-Oriented programming. By now you should know about
Opening windows
How to open windows and make them look the way you want
Communication between windows
How to get JavaScript in one window to affect another window
Communication between frames
How to get JavaScript in one frame to affect other frames
Objects
Objects have properties and methods
The Document Object Model
A browser window is an object that comprises other objects. If you know the hierarchy of the objects in the DOM you know how to affect different aspects of your HTML page.
Although we didn't go into all the details of all the objects in the DOM, we did get an idea of how it works. In the Lesson 4, we'll cover a few aspects of computer programming that haven't been touched on yet. And in Lesson 5, we'll study the DOM further and go into how most of the objects in an HTML document can be accessed and changed.
