app.vue

<template>
  <div id="app">
    <router-view v-if="isRouterAlive"></router-view>
  </div>
</template>
<script>
export default {
  name: ‘App‘,
  provide() {
    return {
      reload: this.reload
    }
  },
  data () {
    return {
      isRouterAlive: 
 
true
    }
  },
  methods: {
    reload() {
      this.isRouterAlive = false;
      this.$nextTick(function () {
        this.isRouterAlive = true;
      })
    }
  }
  
}
</script>

需要刷新的頁面（lscz.vue）中註冊 reload ，調用reload() 方法，

export default {
  components: {
    "v-lsczLeft": lsczLeft
  },
  inject: [
 
‘reload‘],  //註入reload方法
  data() {
    return {
    };
  },
  methods: {
    gdSubmit() {
       this.teload();  //刷新
    }
  }
}
