自定义全局loading框，同理可以根据需求自定义弹框等等
- 这是组件结构
2.如下是laoding.vue内容
<template>
<div class="maskbox" v-if="loading">
<div class="mask"></div>
<div class="sk-fading-circle">
<div class="sk-circle1 sk-circle"></div>
<div class="sk-circle2 sk-circle"></div>
<div class="sk-circle3 sk-circle"></div>
<div class="sk-circle4 sk-circle"></div>
<div class="sk-circle5 sk-circle"></div>
<div class="sk-circle6 sk-circle"></div>
<div class="sk-circle7 sk-circle"></div>
<div class="sk-circle8 sk-circle"></div>
<div class="sk-circle9 sk-circle"></div>
<div class="sk-circle10 sk-circle"></div>
<div class="sk-circle11 sk-circle"></div>
<div class="sk-circle12 sk-circle"></div>
</div>
</div>
</template>
<script setup>

- 如下是index.js的内容
import { createApp } from "vue"
// 导入写好的Loading.vue文件
import Loading from "./loading.vue"
export default {
loading: null,
// 每当这个插件被添加到应用程序中时，如果它是一个对象，就会调用 install 方法。如果它是一个 function，则函数本身将被调用。在这两种情况下——它都会收到两个参数：由 Vue 的 createApp 生成的 app 对象和用户传入的选项。
install(app) {
if (this.loading) {
// 防止多次载入
app.config.globalProperties.$loading = this.loading
return
}
// 创建Loading实例，用于挂载
let instance = createApp(Loading)
// 创建div元素装载Loading对象
let div = document.createElement("div")
div.setAttribute("id","maskbox")
let body = document.body
// 导入body中
body.appendChild(div);
this.loading = instance.mount(div)
// 挂载vue身上
app.config.globalProperties.$loading = this.loading;
}
}
- 在main.js引用
import Loading from "@/components/loading/index"
app.use(Loading)
- 在组件中直接调用
import { getCurrentInstance} from 'vue';
const { proxy } = getCurrentInstance();
proxy.$loading.show();
proxy.$loading.hide();
