前言:
- 在这里首先特别感谢安知鱼大佬的贡献!本文改编自安知鱼的一篇教程——Heo同款loading动画
- 对比上面的安知鱼那篇原文,本文主要新增了关于loading动画下的百分比加载数字的效果
- 本篇文章仅用于交流学习之用,若有侵权行为,请联系我删除
效果展示
1.Butterfly主题自带页面加载动画 preloader:
2.魔改后的loading加载动画:
魔改后的加载动画更加简洁,并且上面的头像、背景颜色等支持用户自定义,能够更加切合自己的网站风格
操作方法
提示:
1.修改 {% label themes/butterfly/layout/includes/loading/fullpage-loading.pug %}
下方的图片链接记得换成自己的

const loadingPercentage = document.getElementById("loading-percentage");
loadingPercentage.style.color = "black";
let loadingPercentageTimer = setInterval(function() {
var progressBar = document.querySelector(".pace-progress");
if (!progressBar) return
var currentValue = progressBar.getAttribute("data-progress-text");

loadingPercentage.textContent = currentValue;
if (currentValue === "100%") {
clearInterval(loadingPercentageTimer);
}
}
}, 100);
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() })
}

2.修改 {% label 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

3.新建博客根目录下{% label source/css/progress_bar.css %} , 也可以不做这一步,那么最后一步中修改配置文件{% label pace_css_url %} 这一项就要留空, 这一步其是修改 pace 加载的胶囊 💊 样式用的

4.修改{% label themes/butterfly/source/css/_layout/loading.styl %} 。
注意:其中**.loading-bg那一项下的background**可以自行修改为自己的色值
(这里其实就是在修改加载背景的颜色,例如我的颜色是浅蓝色:#B0E2FF)

5.在合适的地方加上自定义 css, 其中 background 的 url 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://cdn.jsdelivr.net/gh/HappyLeeCode/IMG/img/avatar.webp) no-repeat center center;
background-size: cover;
}
|
6.最后一步:修改主题目录下{% label _config.yml %}中preloader选项,。
现在 source: 1为满屏加载,无pace胶囊;source: 2为pace胶囊,无满屏动画;source: 3是两者都启用。
