The address is basically changed. If Ext. Dir

If you are waiting for a ride, we will not continue the development process today. Let's talk about background language issues that are commonly concerned. Learning ext JS, I have always stressed that the central idea of learning is"The interface and data are separated". As long as you master this idea and have a deep understanding of the operation process of ext JS, you will not be troubled by the background language usage. It can be said that as long as the idea is clear, it is easy to migrate
