vue父组件向子组件传递函数方法

父组件, fetch-method是函数

<DataTable         ref="table"         :table-data="deviceTable"         :show-columns="deviceColumns"         :selectable="true"         :pageSize="filter.pageSize"         :total="filter.total"         :fetch-method="getDeviceList"         @filter-table="filterTable"         @handle-view="handleView"       />  methods: {       // 获取设备列表     getDeviceList(obj) {       console.log(obj)       const filter = cloneDeep(this.filter);       // console.log(params);       const params = {...filter, ...obj}       console.log(params, 'params');       return assetManage.getDevicesPost(params).then((res) => {         const { items, total } = res.data;         this.deviceTable = items;         this.filter.total = total;         return { items, total }       });     },  

子组件

接受该函数 props: {     fetchMethod: {       type: Function,       default: () => {},     },     //      methods: {     子组件调用父组件的函数     getList() {       this.fetchMethod({         order_by: this.orderBy,         pageNo: this.currentPage,         pageSize: this.realPageSize,       }).then((res) => {         console.log(res, "res");         const { total, items } = res;         this.total = total;         this.tableData = items;       });     },
