<script>
import ReceiveOrderList from '@/views/orderCenter/receiveOrderList'
import TodoListMulti from '@/views/dispatch/todoListMulti'
import SignList from '@/views/dispatch/signList'

export default {
  data() {
    return {
      activeTab: 'ReceiveOrderList',
      componentMap: {
        ReceiveOrderList: ReceiveOrderList,
        TodoListMulti: TodoListMulti,
        SignList: SignList
      }
    }
  },
  computed: {
    activeTabComponent() {
      return this.componentMap[this.activeTab]
    }
  },
  methods: {
    handleTabClick(tab) {
      this.activeTab = tab.name

如果不考虑勋章的话，可以把代码删除掉；
这样就可以实现一个切换不同tab显示不同页面的效果：类似与在iframe中动态变化内容；
此方法的优点就是避免不同页面相同变量引发的混乱，如果是对已有的页面进行整合效果更好！
