2. 页面中引用组件

<calander @assignment="assignment" :propshow="propshow" :boothArray="boothArray" :calanderList="calanderList"></calander> 


<script>
    import calander from '@/components/calander'
    export default {
       components: {
         calander
       },
   data() {
      return {
        calanderList: [],
        boothArray: [],
        propshow: false,
      };
    },
    methods: {
      assignment(){
        // 组件调取父级方法
      },
    }
    }
</script>
