vue实现按需加载组件及异步组件功能

 <template slot-scope="scope">
    <el-button
    type="text"
    size="mini"
    @click="handleSchedule('CustomerInfoSchedule', scope.row.customer_id)"
    >详情</el-button>
    <el-button
    type="text"
    size="mini"
    @click="handleSchedule('VisitRecordSchedule', scope.row.customer_id)"
    >回访</el-button>
    <el-button
    type="text"
    size="mini"
    @click="handleSchedule('AddCustomerSchedule',scope.row.customer_id)"
    >编辑</el-button>
    <el-button
    type="text"
    size="mini"
    @click="handleSchedule('AddPeopleSchedule', scope.row.customer_id)"
    >添加联系人</el-button>
   </template>

 <component 
 :is="currentComponent" 
 :customer_id="customer_id" 
 @componentResult="componentResult"
 >
 </component>

 data() {
 return {
  currentComponent: "",
  customer_id:'',
 }
 }

components: {
  AddCustomerSchedule(resolve) {
  require(["../components/AddCustomer"], resolve);
  },
  AddPeopleSchedule(resolve) {
  require(["../components/AddPeople"], resolve);
  },
  CustomerInfoSchedule(resolve) {
  require(["../components/CustomerInfo"], resolve);
  },
  VisitRecordSchedule(resolve) {
  require(["../components/VisitRecord"], resolve);
  },
 },

// 这里直接接收name,然后相对应的引入组件,同时传值
 handleSchedule(name, id) {
  this.customer_id = id;
  this.currentComponent = name;
  },
 // 这是子组件触发父组件返回回来的方法,因为我的组件都是弹出框
 // 所以在子组件关闭弹出框的时候,我让this.currentComponent为空
 // 同时可以选择性的刷新数据
  componentResult(type) {
  if (type == "upData") {
   this.getTableData();
  } else {
   this.currentComponent = "";
  }
  },
