在 app.vue 組件里面的編寫

<template>
  <div id="app">
    <!-- 路由占位符 -->
    <router-view v-if="isRouterAlive"></router-view>
  </div>
</template>

<script>

export default {
  provide () {
    return {
      reload: this.reload
    }
  },
  data () {
    return {
      isRouterAlive: true
    }
  },
  methods: {
    reload () {
      this.isRouterAlive = false
      this.$nextTick(function () {
        this.isRouterAlive = true
      })
    }
  }
}
</script>

<style lang="less" scoped>

</style>

在需要用到的組件里面引用

export default {
  inject: ['reload'],
  // 監(jiān)聽對話框的確定按鈕
    editCategoryDialogConfirm () {
      let _this = this
        _this.reload()
      })
    }
}
