效果:

父元件程式碼

<template>
  <el-container v-loading="loading" class="container"
                element-loading-background="rgba(1,35,54, 0.8)">
    <h1>這是父元件</h1>

    <HelloWorld msg="Welcome to Your Vue.js App"   @loadTrue="loadTrue" @loadFalse="loadFalse"/>
  </el-container>
</template>

<script>
import HelloWorld from '@/components/HelloWorld.vue'

export default {
  name: 'HomeView',
  components: {
    HelloWorld
  },
  data() {
    return {
      loading: false,
    }
  },
  methods:{
    loadTrue(){
      this.loading = true;
    },
    loadFalse(){
      this.loading = false;
    },
  }
}
</script>
<style scoped>
.container{
  width: 100%;
  height: 800px;
  position: relative;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  background-color: #CAE1FF;
}
</style>

子元件程式碼

<template>
  <div class="hello">
    <h1>{{ msg }}</h1>
    這是子元件
    <div style="margin-top: 20px;">
      <button @click="getList">模擬從後臺獲取資料</button>
    </div>
  </div>
</template>

<script>
let that
export default {
  name: 'HelloWorld',
  props: {
    msg: String
  },
  created(){
    that = this
  },
  methods:{
    getList(){
      this.$emit('loadTrue');
      setTimeout(function(){
        that.$emit('loadFalse');
      },1000)
    }
  }
}
</script>

<style scoped>
.hello{
  width: 50%;
  height: 400px;
  background-color:     #FFF0F5;
}
</style>
