1. Introduction

Introduction to the jQuery Plugin

Though we have chosen to focus the book around jQuery, much of what you’ll learn in this book will be applicable to JavaScript in general and to other JavaScript frameworks you may be using in your work. Much of the effort in the book will be on creating device independent code (works with keyboard and mouse) and using script to inject WAI-ARIA into HTML as needed to dynamically manage roles, states, and properties of various interactive widgets and applications you’ll be introduced to.

Throughout the book you will be building a jQuery-ARIA plugin. We will first provide some background in the first few chapters, then introduce static WAI-ARIA, then move into building the plugin in Chapter 4 up until the end of the book.

As you go through the book you will be building pieces of the library one widget at a time. At the end of the book, when you have submitted all of the assignments, we will provide you with a link to the full library that you can continue to use and build upon.


When creating this book and the jQuery plugin, we have optimized plugin widgets to work with ChromeVox, the screen reader you’ll be introduced to shortly. You may find some inconsistencies in functionality and presentation when using NVDA or JAWS (i.e., other screen readers). Compatibility or limitations across screen readers will be discussed throughout the activities within the book.
