Vue3的CRUD模版（附Demo）

前言

用惯Vue2之后，在碰Vue3后，整体还是有所区别

此文主要做一个回顾总结

假设界面如下：

可CRUD，对应的新增添加一些必选项：

其中数据库的设计如下：

模版

对应需要注意参数位置、初始化表单，重置表单等位置

其首页界面如下：

对应后端的接口传输如下：

js 复制代码

import request from '@/config/axios'

// 企业信息 VO
export interface EnterpriseRegistryVO {
  id: number // 序号
  enterpriseName: string // 企业名称
  creditCode: string // 信用代码
  registrant: string // 注册人
  contactNumber: number // 联系电话
  status: string // 审批通过与否
}

// 企业信息 API
export const EnterpriseRegistryApi = {
  // 查询企业信息分页
  getEnterpriseRegistryPage: async (params: any) => {
    return await request.get({ url: `/dangerous/enterprise-registry/page`, params })
  },

  // 查询企业信息详情
  getEnterpriseRegistry: async (id: number) => {
    return await request.get({ url: `/dangerous/enterprise-registry/get?id=` + id })
  },

  // 新增企业信息
  createEnterpriseRegistry: async (data: EnterpriseRegistryVO) => {
    return await request.post({ url: `/dangerous/enterprise-registry/create`, data })
  },

  // 修改企业信息
  updateEnterpriseRegistry: async (data: EnterpriseRegistryVO) => {
    return await request.put({ url: `/dangerous/enterprise-registry/update`, data })
  },

  // 删除企业信息
  deleteEnterpriseRegistry: async (id: number) => {
    return await request.delete({ url: `/dangerous/enterprise-registry/delete?id=` + id })
  },

  // 导出企业信息 Excel
  exportEnterpriseRegistry: async (params) => {
    return await request.download({ url: `/dangerous/enterprise-registry/export-excel`, params })
  },
}
