Events
We saw in the
last chapter
how the DOM API links the JavaScript language to web pages.
Events are another part of the DOM API and they are what provides the link between the
web page and user interactions. Every time a user interacts with a web page, such as clicking
on a link, pressing a key, or moving a mouse, an
event
occurs that our program can detect
and then respond to.
In this chapter, we'll cover the following topics:
• introduction to events
• adding event listeners
• the event object
• mouse, keyboard and touch events
• removing event listeners
• stopping default behavior
• event propagation
