accessibility program can do. No need to be tested program source code. For example, an article in front of the calculator to maximize the simulation of user operations (some operations such as using Invokepattern, or with the user click the mouse is not the same, but we can simulate the mouse events to achieve the exact same effect). This is easy to understand, after all, the user is using the mouse keyboard operation, not write code to use ... So h

scheme ), this is obviously not in line with our understanding of the structure, and the elastic box does not have this problem. Js: Native js, without using libraries and frameworks. Currently, JavaScript is rarely written, but it mainly involves a little dynamic interaction effect. In fact, it is mostly the interaction of some small controls. Because you do not understand the backend, the data interface related to the backend is currently 0... Originally, this project was designed to practice

meaning is: the popularity and popularization of Rich Internet Applications, such as Flash/Flex, silverlight, XML, and server-side languages (PHP, ASP. NET, JSP, Python) and other languages, front-end development engineers also need to master. The front-end development entry threshold is actually very low. Compared wi

engineering can solve is limited Should not consider people's ability, engineering is a set of non-human, universal approach, talent training is not a category of front-end engineering should not consider upstream decision, demand and rhythm is reasonable, this belongs to the business strategy and management category, cannot rely on the front-

How Should beginners learn the frontend? A big analysis of the development path of web Front-End !, Web Front-end Preface: Excellent Web Front-end development engineers must have both breadth and depth in the Knowledge System! Mus

the ability to quickly learn, you will not be able to keep up with the pace of Web development. Front-end engineers must constantly improve themselves and learn new technologies and models. They cannot adapt to the future simply by relying on today's knowledge. The future of the Web will be quite different from today, and the work of front-

other tool libraries, there is a Vue system itself, suchVue-cli,vue-routerAnd then the extended Vue plug-in.According to Atwood's law:Any application that can be written in JavaScript, will eventually be written in JavaScript.(Translated as follows: Anyone that can be written in JavaScript will be written in JavaScript ). This theory is also applicable to Vue. It is simple and powerful, attracting a lot of ultra-powerful developers or teams and contributing countless useful component libraries

whether you are interested in the front-end. However, the front end is not as simple as the first floor. It is not easy to learn the backend. Now when? The front-end has been learning more than html, css, basic js, and jq. I don'

IntroductionNot long ago, industrial standard testing practices (developed for the quality of the C/S architecture) it still focuses on the front-end function test of the client or the backend scalability test and Performance Test of the server. This "Work separation" is mainly due to the fact that the traditional C/S (Client/Server) architecture is relatively si

javascript prototype and closure series.5. Framework and Class Library We have already described the theoretical knowledge required for web Front-end development. How to practice it? -You can't do it without going around the world. You have to look around the world to see which of the following great bulls have contributed so much to us. Using the following class libraries or frameworks can greatly improve

environment requires some data in the production environment. What should we do at this time ??? ② Small traffic release Sometimes, we may need to release small traffic for testing. On the one hand, to focus on traffic changes and to confirm that there are no errors, we need such a system, at the same time, we also need our visual system to record the conversion rate and other data in various situations. This is just the mobile system that I (from th

knowledge can not adapt to the future. There will be a difference between the future of the web and today, and the job of front-end engineers is to figure out how to manifest this change through their Web applications.Speaking of which, I think of a master said a word: for beginners, new technology is the new technology.For a master, the new technology is just an extension of the old technique.In addition,

If we choose to use a framework, we should follow the rules stipulated by the framework. The main difference between the two is that JQuery is centered on DOM operations, and the framework, which is precisely the MVC Framework, is centered on models, while DOM operations are appended.
