This article shows you what the stages of learning AngularJS are like. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

The first stage: cool

Getting started with AngularJS is always quick, and you can finish a simple page in a few minutes. The Demo on the front page of the official website is already very powerful, and jQuery like me is not very good at it. I will definitely give up jQuery and join AngularJS immediately, because you only need to fix a model and controller, and you don't care about other things on DOM.

At this stage, the main thing is to continue to experience this kind of directive, Shuang a mess. Step by step, the Tutorials on the official website will soon experience most of the functions and e2e functions provided by AngularJS. When I started half-filling (there was only a little water at the time), the new project began. After a week of repeated twists and turns, communication and hoodwinking, I finally persuaded the customer with a Showcase in the final stage and decided to use AngularJS in the new project.

The second stage: pain

The arrival of new requirements makes a team with no AngularJS experience look helpless. All kinds of bizarre questions, let us only constantly google to seek answers. Of course, there are some answers. When faced with nouns such as directive and link, I found that the original AngularJS had such a deep hole. Fortunately, Zaye in the office has a deep foundation in the use of AngularJS and has done a lot of work for the difficult problems at the beginning of the project. The following three articles are all solutions to the problems in our project. * angularjs ng-option ie issue solution

Angular ng-model type format conversion

Input mask of angularjs components

This stage is mainly about all kinds of AngularJS documents and google problems. Sometimes it's like a headless fly bumping around. To get through this stage smoothly, you have to calm down and systematically take a look at the things related to AngularJS. You can also buy the book "developing the next Generation of Web applications with AngularJS". This book is so simple that you can finish it in a day when you are familiar with AngularJS. I heard that there is an open source version on the Internet. If you don't want to spend money, you can also search it.

The third stage: bringing the dead back to life and self-reliance.

When you find that all kinds of directive provided by AngularJS or AngularUI can't meet your requirements, it's time to write directive. This is a bit similar to playing WinForm in the past, when all the controls do not meet the requirements, you have to write your own controls. I think this thing is the core and difficult part of AngularJS.

I have been writing the directive of validate for more than a week, and I have also encountered some problems. However, due to a better understanding of the use of AngularJS, it seems to have a little bit of spectrum to solve the problem.

The fourth stage: in-depth understanding and comprehension

At this stage, I don't think it has been reached yet, because the requirements of the project have not yet required the ability to reach this level. So to reach this stage, I think you need to work hard to find the truth in the AngularJS source code.

The above is what the stages of learning AngularJS are like. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
