需求:将 table 中的 radio 改为 checkbox 并保持同样的效果
HTML部分:
<el-table :data="tableData" tooltip-effect="dark" style=" 100%" ref="multipleTable" @select-all="onSelectAll" @selection-change="selectItem" @row-click="onSelectOp"> <el-table-column type="selection" width="55"> </el-table-column> <el-table-column label="日期" width="120"> <template slot-scope="scope">{{ scope.row.date }}</template> </el-table-column> <el-table-column prop="name" label="姓名" width="120"> </el-table-column> <el-table-column prop="address" label="地址" show-overflow-tooltip> </el-table-column> </el-table>
@select-all="onSelectAll" 全选事件
在点击全选的时候,把所有的选中状态清空,执行 clearSelection() ;
@selection-change="selectItem" 选中某一个 checkbox 事件
做判断,选中数量大于一就把上一个选中的数据勾选状态改为 false ,把新的数据勾选状态设为 true ,并赋值给 multipleSelection 数组,方便调用
@row-click="onSelectOp" 单击某行事件
单击某行,就把某行的选中状态设为 true ,在此之前执行 clearSelection()
具体代码:
methods: { onSelectAll() { this.$refs.multipleTable.clearSelection(); }, selectItem(rows) { if (rows.length > 1) { var newRows = rows.filter((it, index) => { if (index == rows.length - 1) { this.$refs.multipleTable.toggleRowSelection(it, true); return true; } else { this.$refs.multipleTable.toggleRowSelection(it, false); return false; } }); this.multipleSelection = newRows; } else { this.multipleSelection = rows; } }, onSelectOp(row) { this.$refs.multipleTable.clearSelection(); this.$refs.multipleTable.toggleRowSelection(row, true); this.multipleSelection = []; this.multipleSelection.push(row); }, }
