vivo mobile phones have added the option to turn off JavaScript in the latest system update. This change has caused heated discussions and controversy among users. JavaScript is a programming language commonly used in web pages, and many websites rely on JavaScript to implement interactions, animations, and other functions. So, why does vivo add the option to turn off JavaScript in the system settings, and what impact does this change have on users and developers?
First, let’s explore why vivo added the option to turn off JavaScript. In the official system update log, vivo did not clearly explain why it added this option, but simply listed system optimizations and fixed some problems. But from a user perspective, turning off JavaScript can improve the speed and security of web browsing on your mobile phone.
When browsing the web, JavaScript scripts need to be loaded and processed at runtime, which takes up a lot of CPU and memory resources. If the performance of the mobile phone is low or the network is not smooth, it will cause problems such as slow opening of web pages or lags. Turning off JavaScript can alleviate this burden, making web pages load faster. In addition, some websites may use JavaScript to execute malicious code, such as stealing personal information or inserting advertisements, so turning off JavaScript can also improve the security of your phone and reduce the risk of these attacks.
However, turning off JavaScript will also have some negative effects on users and website developers. The first is the user experience aspect. Many websites rely on JavaScript for interaction and animation effects. If JavaScript is turned off, these features will not work properly. For example, on shopping websites, users may not be able to perform operations such as adding items to shopping carts or checking out; on social networking websites, users may not be able to use functions such as message reminders and chats. In addition, some websites will have compatibility issues because they are designed to default to users having JavaScript turned on. After turning off JavaScript, these websites may have problems such as confusing layout and inoperability, resulting in a poor user experience.
For website developers, they need to rely on JavaScript to implement some basic functions of the website, such as form validation, DOM operations, AJAX, etc. If many users turn off JavaScript, these features will be disabled, affecting website interaction and data processing. In addition, some websites for commercial purposes will use JavaScript to track users' browsing history, behavior and other information, and use it for subsequent advertising, marketing, etc. Turning off JavaScript will reduce the data collection efficiency of these websites.
Therefore, turning off JavaScript is a double-edged sword, which can not only improve web page loading speed and security, but also affect user experience and website development. For vivo mobile phone users, whether JavaScript needs to be turned off needs to be decided based on the specific situation. If your mobile phone has poor performance, the network environment is unstable, or the use scenario requires high security, turning off JavaScript may bring benefits. If you need to open some complex websites or use web page interactive functions, you need to keep JavaScript turned on to ensure a good user experience.
For website developers, in order to deal with the situation where users turn off JavaScript, they need to fully consider compatibility issues during design to avoid paralysis of the overall website function due to JavaScript failure. You can use some commonly used technical means such as Graceful Degradation, Progressive Enhancement, etc. to improve the compatibility and adaptability of the website to ensure that users can use the basic functions of the website normally even when JavaScript is turned off.
In general, the introduction of the option to turn off JavaScript in vivo is a change with pros and cons. Users need to make a trade-off between speed, security and user experience, and website developers need to increase their consideration of compatibility to avoid relying too much on JavaScript, which will lead to a decline in user experience. Only by comprehensively considering these factors can we make better use of this new system setting and bring a better experience to users.

HTML and React's Integration: A Practical GuideApr 21, 2025 am 12:16 AMHTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.
React and HTML: Rendering Data and Handling EventsApr 20, 2025 am 12:21 AMReact efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.
The Backend Connection: How React Interacts with ServersApr 20, 2025 am 12:19 AMReact interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.
React: Focusing on the User Interface (Frontend)Apr 20, 2025 am 12:18 AMReact is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
