组件库功能的补充
说明:一般组件库提供的组件是比较通用的,有些不怎么常用,但是会有实际需求的组件功能没有提供。有些是可以直接在原有组件库上增强的,有些就需要自己去实现了。对这些组件功能做一个记录。
一、elementUI的table组件实现动态增删可输入的表格 https://blog.csdn.net/weixin_44490021/article/details/132215845
实现效果
解决方案
总体的解决思路是利用table组件的自定义列模板通过Scoped slot获取到 row, column, $index,拿到每一行的数据,再在动态赋给每行的input和select的v-model值中,直接上代码
template部分
<el-form-item label="添加信息" prop="remark"> <!-- 添加按钮 --> <el-button type="primary" size="mini" @click="handleAdd">添加</el-button> <el-table :data="dataList" size="mini" > <el-table-column type="index" label="序号" width="50"></el-table-column> <el-table-column prop="companyName" label="公司名称" :show-overflow-tooltip="true" min-width="200"> <template slot-scope="scope"> <el-input v-model.trim="scope.row.companyName" placeholder="请输入公司名称" clearable > </el-input> </template> </el-table-column> <el-table-column prop="contractName" label="合同名称" :show-overflow-tooltip="true" min-width="200"> <template slot-scope="scope"> <el-select v-model="scope.row.contractName" placeholder="请选择合同" style="width: 100%" > <el-option v-for="item in contractList" :key="item.dicId" :label="item.dicItemName" :value="item.dicId" ></el-option> </el-select> </template> </el-table-column> <el-table-column prop="type" label="发票类型" :show-overflow-tooltip="true" min-width="100"> <template slot-scope="scope"> <el-select v-model="scope.row.type" placeholder="请选择发票类型" style="width: 100%" > <el-option v-for="item in typeList" :key="item.dicId" :label="item.dicItemName" :value="item.dicId" ></el-option> </el-select> </template> </el-table-column> <el-table-column prop="licenseBeginTime" label="开通时间" :show-overflow-tooltip="true" min-width="180"> <el-date-picker v-model="form.licenseBeginTime" type="date" placeholder="选择开通时间" style="width: 100%" ></el-date-picker> </el-table-column> <el-table-column width="80" label="操作" fixed="right" align="center" class-name="small-padding fixed-width"> <template slot-scope="scope"> <el-button type="text" icon="el-icon-delete" @click="handleDelete(scope.$index, scope.row)" ></el-button> </template> </el-table-column> </el-table> </el-form-item>
script部分
data() { return { dataList: [], contractList: [], typeList: [] } }, methods: { // 添加行 handleAdd() { var _this = this let list = { companyName: '', contractName: '', type: '', licenseBeginTime: '', } _this.dataList.push(list) }, // 删除行 handleDelete(index, row) { var _this = this _this.dataList.splice(index, 1) }, }
