No nonsense extjs getting started tutorial 1 [learning method]

This tutorial is based on the entire learning process and method that I learned from extjs from scratch to formally applied in the project. There are certainly many shortcomings in this tutorial. Please criticize and correct me a lot.

Many books and online tutorials are mostly explained from the API and extjs mechanism. During my study, I found that my colleagues who have never touched extjs or who have little knowledge about JavaScript were very confused when I saw the previous chapters (I am also a newbie ), so I am deeply touched by this. To solve this problem, my learning method is as follows:

1. Start learning from the extjs view.

Such as forms, forms, and trees. First, let's get what you see and get. What you write with extjs is so dazzling that you can mobilize your learning interests and learn how to debug JS during this period.

2. Learn to use APIs.

Learn how to query and use the interfaces provided by Daniel to solve common problems (generally, the results we use can be thought of when making the framework ).

3. Connect the front-end visual components of extjs to the background for interaction.

We have to deal with databases when we are working on various systems. At this stage, we will mainly clarify the interaction between each component and the database.

4. Principles.

For example, the Inheritance Mechanism and events of extjs.

5. Development Instance.

Note: This tutorial is based on extjs3.0 [ext3.0 download] and [ext3.0api download].
