Vue3自定义Loading动画组件

先看看效果

创建global.ts，记录加载加载状态

import { ref } from "vue";

// 加载状态处理
const loadingStatus = ref(false);

export function setLoading(statu: boolean) {
  loadingStatus.value = statu;
}

export function getLoading(): boolean {
  return loadingStatus.value;
}

创建

<template>
  <div class="loading" v-if="getLoading()">
    <div class="loadEffect">
      <span class="circle"></span>
      <span class="circle"></span>
      <span class="circle"></span>
      <span class="circle"></span>
      <span class="circle"></span>
      <span class="circle"></span>
      <span class="circle"></span>
      <span class="circle"></span>
    </div>
  </div>
</template>
<script lang="ts">
import { setLoading, getLoading } from "./global";

export default {
  name: "loading",
  setup() {
    return {
      getLoading,
    };
  },
  mounted() {
    setTimeout(() => {
      if (getLoading()) {
        setLoading(false);
