This article will explain in detail what common functions JavaScript has, and the editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

What are the common functions of JavaScript

Validation of form data

The use of JavaScript scripting language can effectively verify the validity of the data submitted by the client form. If the data is legal, the next step will be performed, otherwise an error reminder will be returned.

Web page special effects

Using JavaScript scripting language, combined with DOM and CSS, you can create colorful web effects, such as flickering text, text rotating around the cursor, and so on.

Interactive menu

Using JavaScript scripts, you can create interactive menus with dynamic effects, which are comparable to the page navigation menus made by falsh.

Dynamic page

Use JavaScript script to access all elements of Web page and use object methods to modify its properties to achieve dynamic page effect, typical applications such as web Tetris, poker games and so on.

Numerical calculation.

JavaScript script provides a wealth of data manipulation methods, can develop web calculators and other applications.

The application of JavaScript script is far from this. JavaScript can combine with XML organically and embed small plug-ins such as Java applet and flash to achieve powerful HTML web pages and attract more customers to browse the website.

Note: any language is great and can do a lot of things, including incredible things, but a few are meaningful and a few are meaningless, but the focus of the language is different.

What are the prospects for JavaScript?

Driven by today's raging rich application development (RAI), cloud computing, Internet of things and server-side development technology (Node.js), JavaScript, as a programming language, is still developing, breaking the limitations of Web foreground and entering new areas of server development, mobile user development (mobile phones, Pad and other handheld facilities) and desktop application development. Web foreground development engineers will have a big gap in the next few years.

Here we focus on cloud computing and rich applications (can be understood as more complex Web applications, such as 115net disk, Baidu network disk, etc.).

With the development of cloud computing and rich applications, more and more operations are done in the cloud (and server clusters). The only interface between the cloud and the customer is the browser, and JavaScript will be the main programming language for human-computer interaction.

You can imagine that when cloud computing is mature, we no longer need complex and professional tools like PhotoShop to solve images. We just need to upload pictures to the cloud and download them when the cloud solution is complete. Among them, the interaction between customers and the cloud is mainly completed by JavaScript.
