With the rapid development of the Internet, browsers have become an indispensable part of our daily lives, and Chrome is one of the most popular browsers. Chrome has excellent performance, excellent compatibility and rich extensions, allowing users to complete many tasks on the browser. However, Chrome’s advanced settings are rarely known. Now let’s discuss Chrome’s advanced settings—JavaScript.
JavaScript is a very powerful scripting language that can achieve dynamic interactive effects on web content. It is often used to write various web page functions, such as web applications, animation effects, web page verification, etc. In the Chrome browser, we can control the behavior of JavaScript through advanced settings, which can not only speed up the loading speed of web pages, reduce resource usage, but also improve the security of web pages.
There are two ways to set JavaScript in Chrome's advanced settings. One is to adjust it through setting options, and the other is to implement it through an extension. Below we will introduce the specific implementation of these two methods respectively.
1. Adjust JavaScript by setting options
First open the Chrome browser, enter "chrome://settings/content" in the address bar, and find "JavaScript" in the pop-up page A column where you can set the behavior of JavaScript.
- Allow all websites to run JavaScript
By default, Chrome will allow all websites to run JavaScript code. If you require full JavaScript support, you can leave this option turned on.
- Block all websites from running JavaScript
If you think some websites are not safe enough, or do not want ads to track your browsing behavior, you can choose this option to turn off JavaScript. Of course, this will result in some website functionality being disabled.
- Allow only specific websites to run JavaScript
If you only trust some websites, such as bank websites or online shopping websites, and want other websites not to be able to run JavaScript, you can choose This item. Just enter the URL of the website in the list.
- Turn on reminders for JavaScript pop-ups
In this item, you can choose whether to turn on reminders for JavaScript pop-ups. Once enabled, you can choose whether to allow pop-ups when a website requests pop-ups.
2. Control JavaScript through extensions
In addition to using the default settings, we can also control the behavior of JavaScript through extensions. These extensions can help you improve the security of your browser and reduce the resource usage of JavaScript on your computer.
The following are several classic Chrome extensions:
- NoScript
NoScript can block scripts for all URLs. By default, NoScript blocks The execution of JavaScript code on all websites will only be lifted with user authorization. This is a way to keep yourself safe, but it also requires more time to configure the whitelist.
- ScriptSafe
ScriptSafe is a tool that can block scripts on all websites. Using ScriptSafe, you can block instructions, disable cookies and HTML5 local storage, etc. without damaging website functionality.
- uBlock Origin
uBlock Origin is an ad blocker that can also block the JavaScript code of certain websites. uBlock Origin blocks all scripts including malicious scripts, cross-site scripting injections and malvertising. Therefore, uBlock Origin also provides a way to basically protect JavaScript.
In short, when using the Chrome browser, we can control the behavior of JavaScript by setting options and using extensions to achieve a better browser experience and better security. We can set it up according to our own needs to make Chrome more suitable for our needs.

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

React in the HTML: Building Interactive User InterfacesApr 20, 2025 am 12:05 AMReact can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.
React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AMReact is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.
The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AMReact's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

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),
