With the development of Internet technology, JavaScript has become an indispensable part of web design, and QQ Browser, as the leading browser brand in China, has always been committed to providing a more complete web browsing experience. Next, let’s take a look at how QQ browser supports JavaScript.

What is JavaScript?

JavaScript, referred to as JS, is a scripting language. It was originally a web page scripting language developed by Netscape. Due to its simplicity, ease of use and ease of learning, it has gradually won wide application and has become an indispensable part of web page development.

JavaScript is a scripting language used to create dynamic web pages and web applications. It can embed code directly in web pages and run in a web browser. When a user opens a web page that contains JavaScript code in a browser, the browser parses the JavaScript code and executes it, thereby achieving interactivity and dynamic effects on the web page.

Why do we need to support JavaScript?

The main role of JavaScript is to achieve interactivity and dynamic effects in Web pages. For example, using JavaScript in a website can achieve the following functions:

1. Form validation: Before the user submits the form, verify the data in the form to ensure the integrity and correctness of the data.
2. Page dynamic effects: For example, when the user clicks a button, a pop-up box or a drop-down menu is displayed, etc.
3. Data interaction: For example, using Ajax technology in Web pages can dynamically load data and improve the response speed of the page.
4. Page jump: Page jump can be achieved through JavaScript, and the method and speed of the jump can be controlled.

Because of the importance of JavaScript, modern web browsers support JavaScript to ensure that users can access and use web pages normally. Each browser has different support for JavaScript, including QQ Browser.
