问题:切换页码时,勾选的数据会被清空
重点看我圈出来的,直接复制,注意,我这里 return row.productId;一般大家的是 return row.id,根据接口定的唯一变量
:row-key="getRowKeys":reserve-selection="true"getRowKeys(row) {return row.productId;},
官方解说
参考我项目里的下方代码
<el-table v-loading="listLoading":data="list"ref="multipleTable"borderfit@selection-change="handleSelectionChange":row-key="getRowKeys"highlight-current-row><el-table-column:reserve-selection="true"type="selection"width="40"></el-table-column><el-table-column align="center"width="180px"label="销售单号"><template slot-scope="scope"><span>{{ scope.row.orderId }}</span></template></el-table-column></el-table>data () {return {getRowKeys(row) {return row.productId;},
rowSelection:'',}methods: {handleSelectionChange(val) {this.rowSelection = val;},
}
