It’s time for a current, definitive JavaScript book, and in this comprehensive beginner’s guide, bestselling author Larry Ullman teaches the language as it is implemented today. Larry demonstrates how to build upon JavaScript’s ease of use, while demystifying its often-cryptic syntax, especially for those who have not programmed before. This book enforces modern JavaScript’s best practices and embraces key Web development approaches such as progressive enhancement and unobtrusive scripting. The author demonstrates loads of real-world code and makes it available for download.

You’ll learn about JavaScript itself and the relationship between JavaScript and HTML. Next you’ll explore variables, common operators, and control structures. Then you’ll create functions, handle events, and do more with HTML forms. You’ll master Ajax, work with frameworks, and use JavaScript with PHP to create a complete example. The result is a book that helps you not just tinker with JavaScript but to thoroughly comprehend it.

This book includes:
  • Easy step-by-step instruction, ample illustrations, and clear examples
  • Real-world techniques to build your skills
  • Insight into best practices from a veteran Web expert
  • Emphasis on strategies for creating reliable code that will work on all of today’s browsers and devices, even those without JavaScript
