As more and more of our work is done through a web browser, and more businesses build web rather than desktop applications, users want web applications that look and feel like desktop applications. Ext JS is a JavaScript library that makes it (relatively) easy to create desktop-style user interfaces in a web application, including multiple windows, toolbars, drop-down menus, dialog boxes, and much more. Yet, most web developers fail to use this amazing library to its full power.

This book covers all of the major features of the Ext framework using interactive code and clear explanation coupled with loads of screenshots. Learning Ext JS will help you create rich, dynamic, and AJAX-enabled web applications that look good and perform beyond the expectations of your users.

From the building blocks of the application layout, to complex dynamic Grids and Forms, this book will guide you through the basics of using Ext JS, giving you the knowledge required to create rich user experiences beyond typical web interfaces. It will provide you with the tools you need to use AJAX, by consuming server-side data directly into the many interfaces of the Ext JS component library. You will also learn how to use all of the Ext JS widgets and components smartly, through interactive examples.By using a series of straightforward examples backed by screenshots, Learning Ext JS 3.2 will help you create web applications that look good and perform beyond the expectations of your users.

  • Learn to build consistent, attractive web interfaces with the framework components
  • Integrate your existing data and web services with Ext JS data support
  • Enhance your JavaScript skills by using Ext's DOM and AJAX helpers
  • Extend Ext JS through custom components
  • An interactive tutorial packed with loads of example code and illustrative screenshots

Shea Frederick

Shea Frederick began his career in web development before the term 'Web Application' was commonplace. By the late 1990s, he was developing web applications for Tower Records that combined the call center interface with inventory and fulfillment. Since then, Shea has worked as a developer for several companies—building and implementing various commerce solutions, content management systems, and lead tracking programs.

Integrating new technologies to make a better application has been a driving point for Shea's work. He strives to use open source libraries as they are often the launching pad for the most creative technological advances. After stumbling upon a young user interface library called YUI-ext several years ago, Shea contributed to its growth by writing documentation, tutorials, and example code. He has remained an active community member for the modern YUI-ext library—Ext JS. Shea's expertise is drawn from community forum participation, work with the core development team, and his own experience as the architect of several large, Ext JS-based web applications. He currently lives in Baltimore, Maryland with his wife and two dogs and spends time skiing, biking, and watching the Steelers.

Shea is the primary author of the first book published on Ext JS, a book which helps to ease beginners into the Ext JS library. He is also a core developer on the Ext JS project along with writing columns for JSMag and running the local Baltimore/DC JavaScript Meetup. His ramblings can be found on his blog, http://www.vinylfox.com and open source code contributions on Github at http://www.github.com/VinylFox/.
