1.data中定义getRowKeys，记录每行的key值
getRowKeys(row) {
return row.id;
},
2.el-table绑定getRowKeys
<el-table
:data="tableData"
@selection-change="handleSelectionChange"
:row-key="getRowKeys"
>
3.将selection列的reserve-selection设为true
<el-table-column
type="selection"
width="50"
align="center"
:reserve-selection="true"
></el-table-column>
4.表格数据选中方法handleSelectionChange
handleSelectionChange(rows) {
this.multipleSelection = rows;
this.select_number = this.multipleSelection.length;
this.select_Id = [];
if (rows) {
rows.forEach((row) => {
if (row) {
this.select_Id.push(row.id);
}
});
}
},
代码整理
<template>
<div>
<el-table @selection-change="handleSelectionChange" :row-key="getRowKeys">
<el-table-column type="selection" width="50" align="center" :reserve-selection="true">
</el-table-column>
</el-table>
<el-pagination>...</el-pagination>
</div>
</template>
<script>
export default {
data() {
return {
multipleSelection: [], // 表格选中
getRowKeys(row) {//记录每行的key值
return row.id;
},
select_number: "", //表格select选中的条数
select_Id: [], //表格select复选框选中的id
}
},
methods: {
handleSelectionChange(rows) {
this.multipleSelection = rows;
this.select_number = this.multipleSelection.length;
this.select_Id = [];
if (rows) {
rows.forEach((row) => {
if (row) {
this.select_Id.push(row.id);
}
});
}
},
}
}
