Chapter 15. Working with the Mouse, Keyboard, and Images

Chapter 15. Working with the Mouse, Keyboard, and Images


In this chapter, we’re going to see some favorite JavaScript topics—working with the mouse, keyboard, images, and handling events in depth. Most visual elements support mouse and keyboard events; to see how they work, we’ll enable the document object’s mouse and keyboard events in this chapter so that you can use the keyboard and mouse anywhere in the entire page.

As we work with the mouse and keyboard, we’ll find that the real keynote for this chapter is event handling. The event handling we’ll see in this chapter has changed radically as browser versions have changed, and we’ll have to take several different event object models into account in our code. In fact, that’s the best place to start this discussion—with an overview of working with events in depth.
