Part 1. Introduction to Ext JS 4.0

This book thoroughly explains and demonstrates how to develop JavaScript applications using the powerful Ext JS framework. The extensive practical examples will help you understand its components and containers, and, even more important, how they can be used together.

Chapter 1 provides an overview of what’s new with Ext JS 4.0. It also covers the fundamental concepts and widgets of the framework, and helps you develop a “Hello World” application. Chapter 2 addresses the basics needed for the foundation of any Ext JS application, such as initialization, DOM element manipulation, and injecting HTML fragment templates with Ajax server data. Chapter 3 explores components and the life cycle of UI building blocks such as viewports, panels, menus, tabs, data grids, dynamic forms, and stylized pop-up windows, as well as containers and layout controls that manage child items.

After reading the chapters in part 1, you’ll see how Ext JS works from the inside out and be ready to explore the many widgets that compose the Ext JS framework.
