应广大小伙伴的要求，更新一下文章，你们要的玩命加载动画教程来了，有句名言怎么说来着，我就像是海绵里的水，快要被你们挤光了。😂😂😂（我改编了一下名言）
首先在站点根目录下新建一个文件夹，名为scripts，紧接着在新建的文件夹下新建一个名为loading-pages的js文件，然后再这个js文件填入下面的代码：
/* global hexo */
"use strict";
hexo.extend.filter.register('after_render:html', function (htmlContent) {
const injectHead =
`<style type="text/css" lang="css">
#loading-container{
position: fixed;
top: 0;
left: 0;
min-height: 100vh;
width: 100vw;
z-index: 9999;
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
background: #FFF;
text-align: center;
/* loader页面消失采用渐隐的方式*/
-webkit-transition: opacity 1s ease;
-moz-transition: opacity 1s ease;
-o-transition: opacity 1s ease;
transition: opacity 1s ease;
}
.loading-image{
width: 120px;
height: 50px;
transform: translate(-50%);
}
.loading-image div:nth-child(2) {
-webkit-animation: pacman-balls 1s linear 0s infinite;
animation: pacman-balls 1s linear 0s infinite
}
.loading-image div:nth-child(3) {
-webkit-animation: pacman-balls 1s linear .33s infinite;
animation: pacman-balls 1s linear .33s infinite
}
.loading-image div:nth-child(4) {
-webkit-animation: pacman-balls 1s linear .66s infinite;
animation: pacman-balls 1s linear .66s infinite
}
.loading-image div:nth-child(5) {
-webkit-animation: pacman-balls 1s linear .99s infinite;
animation: pacman-balls 1s linear .99s infinite
}
.loading-image div:first-of-type {

border-radius: 25px;
-webkit-animation: rotate_pacman_half_up .5s 0s infinite;
animation: rotate_pacman_half_up .5s 0s infinite;
}
.loading-image div:nth-child(2) {
width: 0;
height: 0;

border-right-color: transparent;
border-radius: 25px;

margin-top: -50px;
}
@-webkit-keyframes rotate_pacman_half_up {0% {transform: rotate(270deg)}50% {transform: rotate(1turn)}to {transform: rotate(270deg)}}
@keyframes rotate_pacman_half_up {0% {transform: rotate(270deg)}50% {transform: rotate(1turn)}to {transform: rotate(270deg)}}
@-webkit-keyframes rotate_pacman_half_down {0% {transform: rotate(90deg)}50% {transform: rotate(0deg)}to {transform: rotate(90deg)}}
@keyframes rotate_pacman_half_down {0% {transform: rotate(90deg)}50% {transform: rotate(0deg)}to {transform: rotate(90deg)}}
@-webkit-keyframes pacman-balls {75% {opacity: .7}to {transform: translate(-100px, -6.25px)}}
@keyframes pacman-balls {75% {opacity: .7}to {transform: translate(-100px, -6.25px)}}
.loading-image div:nth-child(3),
.loading-image div:nth-child(4),
.loading-image div:nth-child(5),
.loading-image div:nth-child(6){
background-color: #49b1f5;
width: 15px;
height: 15px;
border-radius: 100%;
margin: 2px;
width: 10px;
height: 10px;
position: absolute;
transform: translateY(-6.25px);
top: 25px;
left: 100px;
}
.loading-text{
margin-bottom: 20vh;
text-align: center;
color: #2c3e50;
font-size: 2rem;
box-sizing: border-box;
padding: 0 10px;
text-shadow: 0 2px 10px rgba(0,0,0,0.2);
}
@media only screen and (max-width: 500px) {
.loading-text{
font-size: 1.5rem;
}
}
.fadeout {
opacity: 0;
filter: alpha(opacity=0);
}
/* logo出现动画 */
@-webkit-keyframes fadeInDown{0%{opacity:0;-webkit-transform:translate3d(0,-100%,0);transform:translate3d(0,-100%,0)}100%{opacity:1;-webkit-transform:none;transform:none}}
@keyframes fadeInDown{0%{opacity:0;-webkit-transform:translate3d(0,-100%,0);}}
</style>
<script>
(function () {
const loaded = function(){
setTimeout(function(){
const loader = document.getElementById("loading-container");
loader.className="fadeout" ;//使用渐隐的方法淡出loading page
// document.getElementById("body-wrap").style.display="flex";
setTimeout(function(){
loader.style.display="none";
},1000);
},1000);//强制显示loading page 1s
};
loaded();
})()
</script>`;
const injectBody = `
<div id="loading-container">
<p class="loading-text">玩命加载中 . . . </p>
<div class="loading-image">
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>
</div>`;
if (/<\/head>/gi.test(htmlContent)) {
let lastIndex = htmlContent.lastIndexOf('</head>');
htmlContent = htmlContent.substring(0, lastIndex) + injectHead + htmlContent.substring(lastIndex, htmlContent.length);
}
if (/<body>/gi.test(htmlContent)) {
let index = htmlContent.indexOf('<body>');
htmlContent = htmlContent.substring(0, index) + injectBody + htmlContent.substring(index, htmlContent.length);
}
return htmlContent;
}, 1);
然后再本地运行查看效果即可。
如果你的主题不是hexo-theme-matery，只需要将上面代码的这块取消注释即可。
将下面的代码
// document.getElementById("body-wrap").style.display="flex";
改为：
document.getElementById("body-wrap").style.display="flex";
基本效果为：
效果二：
<div id="loading-box">
<div class="loading-left-bg"></div>
<div class="loading-right-bg"></div>
<div class="spinner-box">
<div class="configure-border-1">
<div class="configure-core"></div>
</div>
<div class="configure-border-2">
<div class="configure-core"></div>
</div>
<div class="loading-word">加载中...</div>
</div>
</div>
再将下面的代码放在</body>标签之前
<script>
var endLoading = function () {
document.body.style.overflow = 'auto';
document.getElementById('loading-box').classList.add("loaded");
}
window.addEventListener('load',endLoading);
</script>
然后进行相关的部署操作即可
