使用范例：public/index.html【完整代码】

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width,initial-scale=1.0" />
    <link rel="icon" href="<%= BASE_URL %>favicon.ico" />
    <!-- 加载动画 -->
    <style>html,body,#app{width:100%;height:100%;}.d2-home{background-color:#303133;height:100%;display:flex;position:relative;}.d2-home__main{position:absolute;left:50%;top:50%;transform:translateX(-50%) translateY(-50%);}.d2-home__footer{width:100%;flex-grow:0;text-align:center;padding:1em 0;}.d2-home__loading{height:82px;width:82px;}</style>
    <title><%= webpackConfig.name %></title>
  </head>
  <body>
    <noscript>
      <strong
        >We're sorry but test doesn't work properly without JavaScript enabled.
        Please enable it to continue.</strong
      >
    </noscript>
    <div id="app">
      <!-- 动画节点 -->
      <div class="d2-home__main">
        <img
          class="d2-home__loading"
          src="./image/20180919030732834.gif"
          alt="loading"
        />
      </div>
    </div>
    <!-- built files will be auto injected -->
  </body>
</html>

注意：“加载动画不可与请求数据的组件同时使用!” 否则会出现两个加载效果。

  • 在public/index中使用需要谨慎，因为这是全局加载的。
  • 建议使用loading组件

1、四圆点加载动画

压缩版样式文件：

<style>#loading-mask{position:fixed;left:0;top:0;height:100%;width:100%;background:#fff;user-select:none;z-index:9999;overflow:hidden}.loading-wrapper{position:absolute;top:50%;left:50%;transform:translate(-50%,-100%)}.loading-dot{animation:antRotate 1.2s infinite linear;transform:rotate(45deg);position:relative;display:inline-block;font-size:64px;width:64px;height:64px;box-sizing:border-box}.loading-dot i{width:22px;height:22px;position:absolute;display:block;background-color:#1890ff;border-radius:100%;transform:scale(.75);transform-origin:50% 50%;opacity:.3;animation:antSpinMove 1s infinite linear alternate}.loading-dot i:nth-child(1){top:0;left:0}.loading-dot i:nth-child(2){top:0;right:0;-webkit-animation-delay:.4s;animation-delay:.4s}.loading-dot i:nth-child(3){right:0;bottom:0;-webkit-animation-delay:.8s;animation-delay:.8s}.loading-dot i:nth-child(4){bottom:0;left:0;-webkit-animation-delay:1.2s;animation-delay:1.2s}@keyframes antRotate{to{-webkit-transform:rotate(405deg);transform:rotate(405deg)}}@-webkit-keyframes antRotate{to{-webkit-transform:rotate(405deg);transform:rotate(405deg)}}@keyframes antSpinMove{to{opacity:1}}@-webkit-keyframes antSpinMove{to{opacity:1}}</style>

4、请求数据缓慢实现loading提示【推荐】

Vue实现网页首屏加载动画、页面内请求数据加载loading

Ⅰ、封装loading组件【推荐】

loading.vue

<template>
  <div
    class="loadingBox"
    v-show="loading"
    style="background-color: rgba(0, 0, 0, 0.5)"
  >
    <div class="sun-loading"></div>
  </div>
</template>
<script>
export default {
  name: "loading",
  data() {
    return {
      loading: false,
    };
  },
  created() {
    var that = this;
    this.bus.$on("loading", function (data) {
      that.loading = !!data;
    });
  },
};
</script>
<style lang="less" scoped>
.sun-loading {
  width: 45px;
  height: 45px;
  display: block;
  animation: sunLoading 1s steps(12, end) infinite;
  background: transparent
    url("https://assets.yuucn.com/wp-content/uploads/2023/04/1682077944-a72a629df18b8ad.gif?imageMogr2/format/jpg/blur/1x0/quality/60");
  background-size: 100%;
  margin: auto;
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
}
</style>

根文件（App.vue）中使用：

<template>
  <div id="app">
    <keep-alive>
      <router-view v-if="$route.meta.keepAlive" />
    </keep-alive>
    <router-view v-if="!$route.meta.keepAlive" />
    <!--loading加载-->
    <Loading></Loading>
    <div style="height: 30px"></div>
  </div>
</template>
<script>
import Loading from "./components/loading.vue";//引用loading组件
export default {
  components: {
    Loading,
  },
};
</script>

main.js中全局注册

Vue.prototype.bus = new Vue();

页面使用：

//获取列表数据
getList() {
  // 显示loading
  this.bus.$emit("loading", true);
  //请求接口
  fetchList({
    keywords: "水香木鱼",
    pageIndex: this.pageIndex,
    pageSize: this.pageSize,
  })
    .then((res) => {
      this.listData = res.data;
      // 关闭loading
      this.bus.$emit("loading", false);
    })
  .catch((error) => {});
},

Ⅱ、通过elementUI实现

Vue实现网页首屏加载动画、页面内请求数据加载loading

//获取列表数据
getList() {
  // 开始加载loading
  let loading = this.$loading({
    lock: true, //lock的修改符--默认是false
    text: "拼命加载中，请稍候...", //显示在加载图标下方的加载文案
    background: "rgba(0,0,0,0.8)", //遮罩层颜色
    spinner: "el-icon-loading", //自定义加载图标类名
  });
  //请求接口
  fetchList({
    keywords: "水香木鱼",
    pageIndex: this.pageIndex,
    pageSize: this.pageSize,
  })
    .then((res) => {
     this.listData = res.data;
    //关闭loading
    loading.close();
    })
  .catch((error) => {});
},

5、齿轮加载gif效果

Vue实现网页首屏加载动画、页面内请求数据加载loading
压缩版样式：

<style>html,body,#app{width:100%;height:100%;}.d2-home{background-color:#303133;height:100%;display:flex;position:relative;}.d2-home__main{position:absolute;left:50%;top:50%;transform:translateX(-50%) translateY(-50%);}.d2-home__footer{width:100%;flex-grow:0;text-align:center;padding:1em 0;}.d2-home__loading{height:82px;width:82px;}</style>

动画节点：

在id=“app” 标签内加入

<div class="d2-home__main">
  <img
  class="d2-home__loading"
  src="./image/20180919030732834.gif"
  alt="loading"
  />
</div>
