Hi Jesus,

Does this book builds on simple projects from Chapter 2 and continually upgrades the project up to the latter sections? Or are the chapters different from each other.
I sometimes learn better from the latter approach as I could see how the advanced topics of such frameworks makes the code easier

Also, what backend framework did you use on the Ajax part? Is this PHP or Java?

As of the moment, we have no projects that is in need of ExtJS but we mostly used Jquery but that wont stop me from learning another tool..

Thanks and Good luck on your book.

Hi Mark,

The book is structure in a way that allows gradual building upon topics. But, you could easily jump chapters, though it is not recommended.

For instance, you could jump to chapter6, FormPanels. Lets say you want to understand how the complex layouts work, then you'd have to read about layouts in chapter 5. Suppose you wanted to learn how the layouts relate to child elements. You'd then have to migrate to chapter 3, containers.

The backend is PHP, using Code igniter for the MVC (application).

Learning Ext JS from jQuery is a rather different change. Other than JavaScript being the language of choice, jQuery culture differs greatly from Ext JS. For instance, jQuery code is heavy in functional programming, where as Ext JS uses prototypal inheritance in a psuedoclassical manner, injecting the notion of a "superclass" to the language. It also adds OOP principals to utilities such as "extend", which extends a class, whereas in jQuery, "extend" is more of a "apply properties to" type of method.

Best of luck learning the framework.
