Web Front-endJS TutorialIntroduction to the method of displaying process progress bar by combining JS and HTMLIntroduction to the method of displaying process progress bar by combining JS and HTML
The process progress display bar based on the combination of JS and HTML is very practical and can be used on all major websites. The following editor brings you a detailed explanation of the idea of implementing the process progress display bar by combining JS and HTML. What you need Friends, please refer to it
The effect is as follows:
1. Design ideas
It is divided into the following steps (for reference only)
[Vertical Line]
This is made using the ul list tag, which ensures that it can be added at any time and arranged vertically
[Small Circle]
html tag does not seem to provide a small circle tag. Here, p is added with a radian angle to complete. A square p is added with a radian equal to the length (or width) of p to achieve a small circle. . The tape is even simpler. You can add text directly to p
[Text]
The text must follow the small circle, and must be at the same level as the small circle. Here, position: absolute; set top to complete the layout of the same horizontal height
[Dynamic Effect]
The dynamic effect of the front end, needless to say, must be completed by Javascript, here there are two main events that need to be set, namely ,
Mouse-in eventonmouseover="on_mous_move('info_name_1')"
Mouse-out eventonmouseout="on_mous_out('info_name_1')"
The main logic is to add ❤ and two spaces before and after the text, and delete the added content
[Note]
For js, a space is actually 6 characters " ", so you need to pay attention to
when cutting. . . . That's all, here is the source code of the implementation

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AMThe shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AMJavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript: Exploring the Versatility of a Web LanguageApr 11, 2025 am 12:01 AMJavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.
The Evolution of JavaScript: Current Trends and Future ProspectsApr 10, 2025 am 09:33 AMThe latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
Demystifying JavaScript: What It Does and Why It MattersApr 09, 2025 am 12:07 AMJavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
