These two plug-ins are about loading progress animation. Today, let’s learn about the two loading progress plug-ins of pace.js and NProgress.js. Friends who are interested can take a look.
These two plug-ins are about loading progress animation. It should be said that each has its own characteristics. At least for me, each has its own advantages. Today I tinkered with the loading progress animation and studied a lot of (just these two) loading progress animations. I think I have a preliminary understanding of the loading progress animation.
NProgress.js
NProgress is based on jquery, and the version must be >1.8
API:
NProgress.start() — Start the progress bar
NProgress.set(0.4) — Set the progress to a specific percentage position
NProgress.inc() — Increase the progress by a small amount
NProgress.done() — Mark the progress bar as completed
Introduction:
<link rel="stylesheet" type="text/css" href="css/NProgress.css" rel="external nofollow" > <script src="js/NProgress.js" type="text/javascript"></script><br>//还有jquery要引入进来
Usage:
<script>
$(function() {
NProgress.start();
$(window).load(function() {
NProgress.done();
});
</script>Custom animation style:
Write the style we defined into a script tag. This is a little trick.
<script type="text" id="myId"><br> <p class="splash card"><br> <p class="lead" style="text-align:center">不要回来，马上走开...</p> <p class="progress"> <p class="mybar" role="bar"> </p> </p> </p><br></script>
This is css
html,body,iframe{
margin: 0;
padding: 0;
}
#nprogress{
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-color: #f7f7f7;
z-index: 999;
}
.spinner-icon{
display: none!important;
}
.splash {
position:absolute;
top:40%;
left:0;
right:0;
margin: auto;
}
.splash img {
display: block;
margin-left: auto;
margin-right: auto;
height: 100px;
width: 100px;
}
.card {
background-color: #f7f7f7;
padding: 20px 25px 15px;
margin: 0 auto 25px;
width: 380px;
}
.mybar {
background: #29d;
height:10px;
}
.progress {
height: 10px;
overflow: hidden;
}The js code becomes like this:
<script type="text/javascript">
$(function(){
NProgress.configure({
template: $('#myId').html() // template是用来设置动画样式的属性
});
NProgress.start();
});
$(window).load(function(){
NProgress.done();
})
</script>Summary: Control when the animation starts and ends in js, and it has been loaded. Animation style.
The two key pointers in the custom style are the role attributes:
role=bar: horizontal loading bar
role=spinner small rotating circle
Sample 2: (css omitted)
<script type="text" id="myId"> <em id="__mceDel"><em id="__mceDel"><p class="bar" role="bar" style="display=block"><br> <p class="peg"></p><br> </p><br> <p class="spinner" role="spinner"><br> <p class="spinner-icon"></p><br> </p></em></em> </script>
pace.js：
API：
Pace.start: Start displaying the progress bar, if you are not using AMD Or if Browserify is used to load the module, this will be executed by default.
Pace.restart: The progress bar is reloaded and displayed.
Pace.stop: Hide the progress bar and stop loading.
Pace.track: Monitor one or more request tasks.
Pace.ignore: Ignore one or more request tasks.
Usage:
<head> <script src="/pace/pace.js"></script> <link href="/pace/themes/pace-theme-barber-shop.css" rel="external nofollow" rel="stylesheet" /> <br> <!-- 此处的css样式就决定了加载进度动画的样式 --> </head>
Change animation style:
Many kinds of loading progress animations have been designed in pace, you only need to change the css file
Summary:
The advantage of pace is that you can directly import the file. You don’t need to write any code yourself. It comes with a loading progress animation. It just has One drawback is that the loading progress animation provided by the official website does not have a mask layer.
Of course, you can set it up yourself (I don’t know how);
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AMThe main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.
Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AMUnderstanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython 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.
Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
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.
