编写tabs的modelBody后编辑表扩展js在重写后端partial的Service

一、步骤

前端

1.第一步-编写tabs的modelBody

复制下面代码该改的改

<template><div class="vol-tabs" style="height: 390px"><el-tabstype="border-card"style="min-height: 370px;box-shadow: none;border-bottom: 0;border-top: 1px solid #eee;"><el-tab-pane><template #label><span><i class="el-icon-date"></i> 研发产品BOM清单</span></template><!-- 显示操作按钮 --><div><el-button type="primary" icon="Close" link @click="del('table1')">删除行</el-button><el-button type="success" icon="Plus" link @click="add('table1')">添加行</el-button><el-buttontype="info"icon="Refresh"link@click="$refs.table1.load()">刷新</el-button></div><!-- :defaultLoadPage="false"打开窗口禁用默认加载数据 --><vol-tableref="table1":clickEdit="true":loadKey="true":columns="tableColumns1":pagination-hide="false":height="275":url="table1Url":index="true":defaultLoadPage="false"@loadBefore="loadTableBefore"@loadAfter="loadTableAfter":beginEdit="beginEdit"></vol-table></el-tab-pane><!-- 从表2 --><el-tab-pane :lazy="false" label="检测报告"><template #label><span><i class="el-icon-date"></i> 检测报告</span></template><!-- 从表2配置 ,双击可以开启编辑--><div style="padding-bottom: 10px"><el-button type="primary" icon="Close" link @click="del('table2')">删除行</el-button><el-button type="success" icon="Plus" link @click="add('table2')">添加行</el-button><el-buttontype="info"icon="Refresh"link@click="$refs.table2.load()">刷新</el-button></div><vol-tableref="table2":loadKey="true":clickEdit="true":columns="tableColumns2":pagination-hide="false":height="275":url="table2Url":defaultLoadPage="false"@loadBefore="loadTableBefore"@loadAfter="loadTableAfter":index="true":beginEdit="beginEdit"></vol-table></el-tab-pane></el-tabs></div>
</template>

{this.$Message.info("请先选择研发方案");}}},//如果要获取页面的参数请使用 this.$emit("parentCall",见下面的使用方法modelOpen() {let $parent;//获取生成页面viewgrid的对象this.$emit("parentCall", ($this) => {$parent = $this;});//当前如果是新建重置两个表格数据if ($parent.currentAction == "Add") {this.$refs.table1.reset();this.$refs.table2.reset();} else

};
</script>
<style lang="less" scoped>
.vol-tabs {background: white;
}
</style>

2.第二步编辑表扩展js

导入modelBody

import App_ExpertModelBody from '@/extension/business/cy_dev_business/extend/RD_PROJECT_ModelBody'

注册组件

components: {//查询界面扩展组件gridHeader: gridHeader,gridBody: '',gridFooter: '',//新建、编辑弹出框扩展组件modelHeader: '',modelBody: App_ExpertModelBody,modelFooter: '',},

修改表扩展js—从表增改逻辑—请求后台

addBefore(formData) { //弹出框新建或编辑功能点保存时可以将从表1，从表2的数据提到后台this.setFormData(formData);return true;},addAfter(result) {//编辑保存后result返回的状态及表单对象// this.$Notice.success({ title: this.detailOptions.cnName + '编辑完成后：', desc: '返回的数据' + JSON.stringify(result) });result.status == true ?this.$Message.success('保存成功') :this.$Message.error('失败！' + result.message)return true;},updateBefore(formData) { //编辑时功能点保存时可以将从表1，从表2的数据提到后台this.setFormData(formData);return true;},updateAfter(result) {//编辑保存后result返回的状态及表单对象// this.$Notice.success({ title: this.detailOptions.cnName + '编辑完成后：', desc: '返回的数据' + JSON.stringify(result) });result.status == true ?this.$Message.success('保存成功') :this.$Message.error('失败！' + result.message)return true;},setFormData(formData) { //新建或编辑时，将从表1、2的数据提交到后台,见后台App_ReportPriceService的新建方法//后台从对象里直接取extra的值let extra = {table1List: this.$refs.modelBody.$refs.table1.rowData,//获取从表1的行数据table2List: this.$refs.modelBody.$refs.table2.rowData//获取从表2的行数据}formData.extra = JSON.stringify(extra);},

结果类似如下图：

重写表的add和Update方法
