script.
const preloader = {
endLoading: () => {
document.body.style.overflow = 'auto';
document.getElementById('loading-box').classList.add("loaded")
},
initLoading: () => {
document.body.style.overflow = '';
document.getElementById('loading-box').classList.remove("loaded")

}
}
window.addEventListener('load',()=> { preloader.endLoading() })

if (!{theme.pjax && theme.pjax.enable}) {
document.addEventListener('pjax:send', () => { preloader.initLoading() })
document.addEventListener('pjax:complete', () => { preloader.endLoading() })
}

修改themes/butterfly/layout/includes/loading/index.pug

if theme.preloader.source === 1
include ./fullpage-loading.pug
else if theme.preloader.source === 2
include ./pace.pug
else
include ./fullpage-loading.pug
include ./pace.pug

新建source/css/progress_bar.css, 也可以不做这一步下面配置文件pace_css_url这一项就要留空, 这一步是修改 pace 加载的胶囊 💊 样式用的

修改themes/butterfly/source/css/_layout/loading.styl, 注意其中颜色代码--anzhiyu-card-bg等需自行替换为自己的色值。

#loading-box
.loading-img
width: 100px;
height: 100px;
border-radius: 50%;
margin: auto;
border: 4px solid #f0f0f2;
animation-duration: .3s;

.loading-image-dot

&.loaded
.loading-bg
opacity: 0;
z-index: -1000;

@keyframes loadingAction
0% {
opacity: 1;
}

100% {
opacity: .4;
}

在合适的地方加上自定义 css, 其中 backgroundurl 即为 loading 的图片地址

不会的同学参考Hexo 博客添加自定义 css 和 js 文件

.loading-img {
background: url(https://npm.elemecdn.com/anzhiyu-blog@2.1.1/img/avatar.webp) no-repeat center center;
background-size: cover;
}

最后修改_config.butterfly.ymlpreloader选项, 改完以后source: 1为满屏加载无pace胶囊,source: 2pace胶囊无满屏动画, source: 3是两者都启用。
