Ext JS Cookbook

So, what’s this book all about you may ask. This book was written with hope that it will bring you closer Ext JS framework that is really powerful and has cool features. This book will not tell you how to get started with Ext JS or explain datatypes, variables and syntax (although it says something about that) since it’s not it’s main point of interest. You’ll also get all source codes used in this book so it’s easier for you to follow. (I suggest you write them by your self because you’ll get more familiar with framework).

Who Is This Book ForTop

Author himself says that this book is for those who want to learn useful techniques on working with Ext JS with explanations and those who already have experience in that technology. I would extend that a little bit and would say that it’s not just for those who have experience in Ext JS, but for all those who have experience in Javascript. If you know jQuery, it’s a big plus because they work almost the same way. I’ve never before worked with Ext JS, but since I’ve experience in Javascript and jQuery, it was not hard for me to understand how it works because it’s just a framework, not new programming language.

What Will This Book Teach YouTop

I would not say teach you so it means “This is how you do it”, but in a way that it will give you some kind of a template that you can modify to get what you want. This book has recipes on how to do something, but each one of them can be extended or merged with any other. You’ll see how certain component are combined to get something new. When you’ll be reading this book, just remember that the way author did it is not the only way how it could be done. I think author wanted to say the same thing.

About ChaptersTop

It has 10 chapters and each one of them has about 10-11 recipes. They start with elementary stuff like modifying DOM, detecting browser, converting variable types and working with string. Then you’ll have a chance to work with user interface, forms, and grids. After that you’ll learn how to combine what you’ve learned and create editable grids, tabs, menus and charts. At the end you’ll be introduced to design patterns used in Ext JS.

How It’s WrittenTop

To better understand following images, this is convention they used.

Conventions

It’s written using template similar to this.

Template

You’ll find images that show you what you are trying to create and if recipe includes some kind of flow you’ll see images connected with arrows so you can see how changes are happening. You’ll also find arrow pointing to interesting areas on image.

Arrows pointing to interesting area

You may find it confusing later when you have 4-5 pages of code and after that it’s explanation in 15-20 rows of text, but don’t be. It’s short explanation because some component used in there was explained in some other recipe. That’s why you have to read See also… section, where you’ll find references tho those components that where not explained to good.

In There’s more… section, you’ll find tips on how to do it in a different way or how to combine it with other components.

There's more part 1

There's more part 2

You may find Getting ready… section that will tell you what are dependencies and where to find them so you can follow recipe.

Favorite ChapterTop

My favorite chapter is Chapter 8 – Making Progress With Menus and Toolbars. Why? Because menus and toolbars are something hard to do using CSS and XHTML and Ext JS has a simple way of doing is by defining some CSS and creating toolbar using Ext.Toolbar.

Toolbar

There is also shown how to do drop down menus and it shows what I’ve been talking about on how you can combine components to get something new. Here it’s shown how to combine color picker, date picker, menu and toolbar to create a good looking menu where you can pick color or date.

ConclusionTop

Well, there is nothing more I can tell you about this book. I liked it a lot and started to consider using Ext JS as my primary Javascript framework and not jQuery and will learn more about Ext JS. I may buy an other book. If you want to use Ext JS in your projects and you need some kind of cheat sheet or you just want to learn Ext JS this is what you need. It’s written in a way that it’s easy to follow and if you have experience in Javascript but not in Ext JS (like myself) you’ll still be able to catch everything.
