Students learn programming is not new to JavaScript, JavaScript front-end technology is a very important element. For example, the effect of switching pages, animation, games and more pages. In fact, we work with HTML and CSS technology can already build a variety of page styles, but you really want to achieve the effect of dynamic pages, but also requires the use of JavaScript technology. Xiao Bian below to find out more about what JavaScript major role Yes.
Wikipedia definition of JavaScript is a scripting language literal style, is a dynamically typed, weakly typed, prototype-based language, built-in support types. Although JavaScript uses the Java name, but in fact there is no relationship between JavaScript and Java.
What JavaScript main role is it?
As already mentioned JavaScript can achieve the effect of switching the page, animation, games and other results page. However JavaScript to assume more responsibility. Especially when the rise of Ajax technology, the site's user experience has been greatly improved. For example, When people type words in Baidu's search box, the page will IntelliSense next to search the contents of a user, a drop-down menu, to achieve this effect can not be separated JavaScript. In addition, the use of JavaScript has not only limited to the browser, Node.js makes the emergence of developers to write JavaScript code on the server side, JavaScript makes the application more widely.
To conclude, JavaScript daily use can be summarized in the following main areas:
1, embed dynamic text and HTML pages
2, time to make the appropriate browser
3, read HTML element
4, the verification data is submitted to the server before the data
5, to detect the visitor's browser information
6, control cookies, including creating and modify.
7, node.js server side based programming techniques.
Updated front-end technology so rapidly in this environment, front-end engineers to maintain self-learning ability is especially important. Therefore, the "what to learn" "how to learn" that we have to urgently address the problem. This is my front-end exchange study qun: front 603, the middle is 985, followed by 993. If you need to download learning materials on the inside. I'm doing this for ten years, have questions feel free to ask me, learning, learning efficiency and so on.
There are already many large Internet companies to establish a separate JavaScript technology development positions. Especially in the large front-end technology background continuous development of front-end development engineers from the very beginning to develop simple page before and after the now-terminal fusion development, cross-platform development and other fields filling towering. As the technical direction of a very promising future JavaScript will certainly occupy a more important role in the future of the Internet field. Self-learning front-end technology alone is unable to adapt to real employment needs of business now.
