vue+element实现批量删除功能的示例

今年开始学习vue+element实现后台开发,在实现批量删除功能时有2个小知识点记录在下:
1、如何实现单击行交替选中当前行的复选框,element官网的table实例中没有找到。――通过row-click和toggleRowSelection实现
2、如何获取选中行的值来实现批量删除。――通过selection-change实现
代码如下
html:
<div class="row mt30 pl15"> <el-button type="warning" @click="delGroup" :disabled="this.sels.length === 0">批量删除</el-button><!--disabled值动态显示,默认为true,当选中复选框后值为false--> </div> <el-table :data="tableList" :fit="true" @row-click="handleCurrentChange" @selection-change="selsChange" ref="table"> <el-table-column type="selection" width="55" reserve-selection=""></el-table-column> <el-table-column prop="id" label="ID" width="150" class-name="bg_blue"></el-table-column> <el-table-column prop="cpsProductId" label="商品ID" width="200"></el-table-column> <el-table-column prop="productName" label="商品名称" width="200" show-overflow-tooltip></el-table-column> <el-table-column label="图片" width="200"> <template scope="data1"> <img :src="data1.row.imgsrc" class="mt10 mb10"> </template> </el-table-column> <el-table-column label="操作" align="center"> <template scope="scope"> <el-button type="primary" size="small" @click="onEditSku(scope.row.id)">编辑</el-button> <el-button size="small" @click="onDelProduct(scope.row.id)">删除</el-button> </template> </el-table-column> </el-table>
js:
<script> export default { name: 'product', mounted() { this.onSearch() }, data() { return { sels: [],//选中的值显示 tableList: [], total: 0, start: 0, size: 10 } }, methods: { selsChange(sels) { this.sels = sels }, delGroup() { var ids = this.sels.map(item => item.id).join()//获取所有选中行的id组成的字符串,以逗号分隔 }, handleCurrentChange(row, event, column) { this.$refs.table.toggleRowSelection(row) } } } </script>
