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>

Copy after login

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;
 }

Copy after login

The js code becomes like this:

<script type="text/javascript">
 $(function(){
  NProgress.configure({
  template: $(&#39;#myId&#39;).html() // template是用来设置动画样式的属性
  });
  NProgress.start();
 });
 $(window).load(function(){
  NProgress.done();
 })
 </script>

Copy after login

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.
