The book Learning Ext JS, written by Shea Frederick, Colin Ramsay and Steve ‘Cutter’ Blades, is a good source for newbies to become familiar with the Ext JS framework, as well as for advanced developers to fill in the gap from the official documentation.
The book covers Windows, Layouts, Toolbars, Buttons, Menus, Trees, Grids and Forms. Throughout the examples, a good emphasis in given to show how the data is acquired and manipulated: from reading the data in JSON, recording it, mapping it in a grid or a form, to formatting it using templates or renderers. It also explains how to find, filter and sort data both in the client-side and in the server-side,
Adding Effects and Drag-and-Drop functionality is well explained. However, DOM manipulation, Object-Oriented programming and the Event-Driven model is only briefly mentioned. This is where a book tailored for more advanced developers could pick up from.
I strongly recommend this book for anyone interested in creating Rich Internet Applications.
