Progress bar effect implemented with CSS JS_javascript skills

May 16, 2016 pm 07:12 PM

The progress bar allows users to see how much the web page has been downloaded when they enter your website. The effect of this is very obvious - it makes the user's waiting time longer, which can effectively make up for the shortcomings of slow space (of course , your space is too slow, I suggest you change the space, haha)
Okay, now I will give you two examples
One is implemented using FLASH (many websites on the Internet are like this, so I won’t go into details)
One is implemented using dynamic GIF (you can check this out from Microsoft’s official download page, I won’t talk about it)
Here, our focus is to use CSS JS to achieve this effect
Okay, no more nonsense Say more, let’s start
First, write a piece of HTML code


33%

Okay, now let’s write the CSS code
}

This is what we want the background color of the progress bar to be #000, black, and add a border

j
The next step is to design with loadcss

#loadcss {

display: block ; /*very important, make it into blocks*/

background-color: # 0df;

text -align : center;

                                                                                                                                                                                   🎜>Haha, but now the entire progress bar is full

So, how can we display the progress?

Here, we can use a clever method

Modify the HTML code slightly

Look at the following code:




                                                                                               🎜>
Hehe, how about it, now it shows 33%

But, he doesn’t move, right? Okay, let’s use JS to implement it (this JS is not designed by me) ...)




OK, this JS mainly consists of two functions, one is load , used to open the progress bar,

                                              setload is used to control the position of the progress bar. Set a counter in setload and run steload every 0.5 seconds.
OK, this JS should be placed in HEAD and then called in BODY, that is,

Haha, try running the webpage now, haha, is it successful?

Demystifying JavaScript: What It Does and Why It Matters Demystifying JavaScript: What It Does and Why It Matters Apr 09, 2025 am 12:07 AM

JavaScript 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.

The Evolution of JavaScript: Current Trends and Future Prospects The Evolution of JavaScript: Current Trends and Future Prospects Apr 10, 2025 am 09:33 AM

The 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.

JavaScript Engines: Comparing Implementations JavaScript Engines: Comparing Implementations Apr 13, 2025 am 12:05 AM

Different 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.

Python vs. JavaScript: The Learning Curve and Ease of Use Python vs. JavaScript: The Learning Curve and Ease of Use Apr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

JavaScript: Exploring the Versatility of a Web Language JavaScript: Exploring the Versatility of a Web Language Apr 11, 2025 am 12:01 AM

JavaScript 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.

From C/C   to JavaScript: How It All Works From C/C to JavaScript: How It All Works Apr 14, 2025 am 12:05 AM

The 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.
