In addition to HTML and CSS, JavaScript represents one of the main tools web developers use to create rich, responsive web and mobile applications. It's use has expanded with the use of jQuery and AJAX and has evolved JavaScript to become much more than just a scripting language used to manipulate the user interface. This coursware is intended for use as a three-day course, or can be used by students who wish to study on their own to learn JavaScript. Readers will learn how to create basic statements in JavaScript, how to declare and use primitive and complex variables and data types (including objects), how to create and use Functions and Expressions and how to match patterns using Regular Expressions. In addition, students will see how to manipulate the Document Object Model (DOM), how to handle keyboard and screen events, how to validate form input with JavaScript and how to debug and handle errors in their JavaScript code.
This book will help students learn to
Use features of the most recent version of JavaScript
Use complex and primitive variables and data types
Work with Objects in JavaScript
Use Regular Expressions for pattern matching
Handle and respond to screen and keyboard events
Validate form input with JavaScript
