在子组件中接收参数

<script>
  import Tools from '../../tools/tools'

  export default {
    data() {
      return {
        HT: new Tools(),// 实例一个对象
        HTobjData: '',// HT的一个大集合
      }
    },
    props: {
      callbackdata: {
        type: Object,
        default: {}
      }
    },
    mounted() {

    },
    methods: {
      init(callbackdata) {
        const self = this;
        self.HTobjData = self.HT.init(callbackdata, self, Handsontable);
      }
    },
    components: {},

    watch: {
      callbackdata(newV) {
        this.init(newV);
      }
    }

  }
