JD.com does not allow javascript

JD.com does not allow JavaScript, which is a confusing policy. Javascript is a popular programming language that is widely used in web applications. However, JD.com blocked its use on its website. Why did JD.com do this? This article will explore this issue and explore the role of JavaScript on e-commerce websites.

First of all, we need to understand the role of Javascript on web pages. Javascript is a scripting language that runs in a web browser. It can be used to change the appearance and interactive behavior of web pages, making them more vivid and interactive. For example, when you shop online, the drop-down menus and tabs on the website are handled by JavaScript. In addition, JavaScript can also be used to validate form inputs, call web service APIs, and implement animation effects, etc.

However, the use of JavaScript on JD.com is prohibited. This means that the JD.com website will not run any JavaScript code, whether it is code written by the website itself or code provided by other third-party libraries. When users visit JD.com’s website, they will not see any interactive elements generated by JavaScript.

So, why does JD.com prohibit the use of JavaScript on its website? In fact, the reasons are very complicated, but there are two main points:

1. Security issues

Some attackers use JavaScript vulnerabilities to inject malicious code into the website, thereby attacking the site or Steal users' sensitive information. By disabling JavaScript, JD.com can reduce the risk of this attack. This approach is also a common approach for many websites today.

2. Website efficiency and performance issues

JavaScript code is executed on the client browser. When a client is accessing a website that contains a lot of JavaScript code, too many network requests may occur, causing the website to load slowly. In order to provide customers with a better user experience and improve website performance, JD.com has decided to disable JavaScript.

However, these limitations have a negative impact on the user experience of most websites. Modern e-commerce websites often use JavaScript to provide interactivity and animation effects, which allows customers to better browse and purchase items. By disabling JavaScript, JD.com's website may appear outdated, less vivid, and the user interaction experience is not good enough.

In addition, some developers believe that JD.com’s decision to not allow JavaScript is a bad decision. They believe that disabling JavaScript hinders developer creativity and limits website functionality and innovation. At the same time, this may also lead to independent developers being reluctant to develop applications for the JD platform because they have to use different programming languages.

Overall, JD.com’s decision to not allow the use of JavaScript on its website is a controversial one. If you are a JD.com website user, you may feel that the website lacks modernity and interactivity, which makes you feel uncomfortable. However, if you are a website developer, you may be more concerned about the security and performance of the website and understand JD.com’s practices.

In any case, the answer to this question may ultimately depend on JD.com’s user and developer feedback. If they generally believe that disabling JavaScript will have a negative impact, then JD.com may be forced to reconsider their decision.
