这篇文章来完成用户组件也就是增删改查表格

用户页面信息页面由头部，表格,和弹框组成

<template><div class="user-header"><el-button type="primary" @click="handleAdd">新增</el-button><el-form :inline="true" :model="formInline"><el-form-item label="请输入"><el-input placeholder="请输入用户名" v-model="formInline.keyWord"></el-input></el-form-item><el-form-item><el-button type="primary" @click="handleSearch">搜索</el-button></el-form-item></el-form></div><div class="table"><el-table :data="tableData" style="width:100%"><el-table-columnv-for="item in tableLabel":key="item.prop":width="item.width ? item.width :125":prop="item.prop":label="item.label"></el-table-column><el-table-column fixed="right" label="Operations" min-width="150"><template #="scope"><el-button type="primary" size="small" @click="handleEdit(scope.row)">编辑</el-button><el-button type="danger" size="small" @click="handleDelete(scope.row)">删除</el-button></template></el-table-column></el-table><el-paginationclass="pager"backgroundlayout="prev, pager,next"size="small":total="config.total"@current-change="handleChange"></el-pagination></div><el-dialogv-model="dialogVisible":title="action === 'add' ?

在api文件夹中api.js文件加入

getUserData(data){return request({url:"/home/getUserData",method:'get',data})},deleteUser(data){return request({url:"/home/deleteUser",method:'get',data})},addUser(params) {return request({url: '/user/addUser',method: 'post',data: params})},editUser(params) {return request({url: '/user/editUser',method: 'post',data: params})},

在mock.js中加入

Mock.mock(/api\/home\/getUserData/,"get",userApi.getUserList)Mock.mock(/api\/home\/deleteUser/,"get",userApi.deleteUser)Mock.mock(/api\/user\/addUser/,"post", userApi.createUser)Mock.mock(/api\/user\/editUser/, "post",userApi.updateUser)

mockData文件夹中加入user.js模拟数据

import Mock from 'mockjs'// get请求从config.url获取参数，post从config.body中获取参数function param2Obj(url) {const search = url.split('?')[1]if (!search) {return {}}return JSON.parse('{"' +decodeURIComponent(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g, '":"') +'"}')}let List = []const count = 200//模拟200条用户数据for (let i = 0; i < count; i++) {List.push(Mock.mock({id: Mock.Random.guid(),name: Mock.Random.cname(),addr: Mock.mock('@county(true)'),'age|18-60': 1,birth: Mock.Random.date(),sex: Mock.Random.integer(0, 1)}))}export default {/*** 获取列表* 要带参数 name, page, limt; name可以不填, page,limit有默认值。* @param name, page, limit* @return {{code: number, count: number, data: *[]}}*/getUserList: config => {//limit默认是10，因为分页器默认也是一页10个const { name, page = 1, limit = 10 } = param2Obj(config.url)const mockList = List.filter(user => {//如果name存在会，根据name筛选数据if (name && user.name.indexOf(name) === -1) return falsereturn true})//分页const pageList = mockList.filter((item, index) => index < limit * page && index >= limit * (page - 1))return {code: 200,data: {list: pageList,count: mockList.length, //数据总条数需要返回}}},//在原来的export default 中添加/*** 删除用户* @param id* @return {*}*/deleteUser: config => {const { id } = param2Obj(config.url)if (!id) {return {code: -999,message: '参数不正确'}} else {List = List.filter(u => u.id !== id)return {code: 200,message: '删除成功'}}},/*** 增加用户* @param name, addr, age, birth, sex* @return {{code: number, data: {message: string}}}*/createUser: config => {const { name, addr, age, birth, sex } = JSON.parse(config.body)List.unshift({id: Mock.Random.guid(),name: name,addr: addr,age: age,birth: birth,sex: sex})return {code: 200,data: {message: '添加成功'}}},/*** 修改用户* @param id, name, addr, age, birth, sex* @return {{code: number, data: {message: string}}}*/updateUser: config => {const { id, name, addr, age, birth, sex } = JSON.parse(config.body)const sex_num = parseInt(sex)List.some(u => {if (u.id === id) {u.name = nameu.addr = addru.age = ageu.birth = birthu.sex = sex_numreturn true}})return {code: 200,data: {message: '编辑成功'}}}}

有了相应的请求数据就可以实现增删改差以及相应的功能

<script setup>
//
import {ref,getCurrentInstance,onMounted,reactive,nextTick} from 'vue'const tableLabel = reactive([{prop:'name',label:'姓名'},{prop:'age',label:'年龄'},{prop:'sexLabel',label:'性别'},{prop:'birth',label:'出生日期',width:200},{prop:'addr',label:'地址',width:400},])const tableData =ref([])const {proxy} = getCurrentInstance()const getUserData = async () => {let data = await proxy.$api.getUserData(config)// console.log(data)tableData.value = data.list.map(item =>({...item,sexLabel: item.sex === 1 ? '男' : '女'}))config.total = data.count}const formInline = reactive({keyWord:''})const config =reactive({name:'',total:0,page:1})const handleSearch=() => {config.name = formInline.keyWordgetUserData()}const handleChange = (page) => {config.page = pagegetUserData()}const handleDelete =(val) => {ElMessageBox.confirm("你确定要删除吗?").then(async () => {await proxy.$api.deleteUser({id:val.id})ElMessage({showClose:true,message:'删除成功',type:'success'})getUserData()})}const action =ref('add')const dialogVisible = ref(false)const formUser = reactive({sex:"1"})const rules = reactive({name: [{ required: true, message: "姓名是必填项", trigger: "blur" }],age: [{ required: true, message: "年龄是必填项", trigger: "blur" },{ type: "number", message: "年龄必须是数字" },],sex: [{ required: true, message: "性别是必选项", trigger: "change" }],birth: [{ required: true, message: "出生日期是必选项" }],addr:[{ required: true, message: '地址是必填项' }]})//这个方法之前定义过const handleAdd = () => {action.value="add"//打开对话窗dialogVisible.value=true}//对话框右上角的关闭事件const handleClose = () => {//获取到表单dom，执行resetFields重置表单// proxy.$refs["userForm"].resetFields()//关闭对话框dialogVisible.value=false}//对话框右下角的取消事件const handleCancel = () => {// proxy.$refs["userForm"].resetFields()dialogVisible.value=false}//格式化日期，格式化为：1997-01-02这种const timeFormat = (time) => {var time = new Date(time);var year = time.getFullYear();var month = time.getMonth() + 1;var date = time.getDate();function add(m) {return m < 10 ? "0" + m : m;}return year + "-" + add(month) + "-" + add(date);}const onSubmit = () => {//执行userForm表单的validate进行规则校验，传入一个回调函数，回调函数会接受到一个是否校验通过的变量proxy.$refs["userForm"].validate(async (valid)=>{//如果校验成功if (valid) {//res用于接收添加用户或者编辑用户接口的返回值let res=null//这里无论是新增或者是编辑，我们都要对这个日期进行一个格式化//如果不是1997-01-02这种格式，使用timeFormat方法进行格式化formUser.birth=/^\d{4}-\d{2}-\d{2}$/.test(formUser.birth) ? formUser.birth : timeFormat(formUser.birth)//如果当前的操作是新增，则调用新增接口if (action.value == "add") {res = await proxy.$api.addUser(formUser);}else if(action.value == "edit"){res = await proxy.$api.editUser(formUser)}//如果接口调用成功if(res){//关闭对话框，重置表单，重新请求用户数据dialogVisible.value = false;proxy.$refs["userForm"].resetFields()getUserData()}//如果校验失败}else {ElMessage({showClose: true,message: "请输入正确的内容",type: "error",})}})}const handleEdit = (val) => {action.value="edit"dialogVisible.value=truenextTick(()=>{//因为在第一次显示弹窗的时候form组件没有加载出来，如果直接对formUser赋值，这个值会作为form表单的初始值//所以使用nextTick，赋值的操作在一个微任务中，这样就可以避免在from表单加载之前赋值Object.assign(formUser,{...val,sex:""+val.sex})//这里需要改变sex数据类型，是因为el-option的value有类型的校验})}onMounted(() => {getUserData()})</script>

用户表格实现完成
请添加图片描述

接下来实现面包屑组件

<template><div class="tags"><el-tagv-for="(tag,index) in tags":key="tag.name":closable="tag.name !== 'home'":effect = "route.name === tag.name ? 'dark': 'plain'"@click="handleMenu(tag)"@close="handleClose(tag,index)">{{tag.label}}</el-tag></div></template><script setup>import {ref,computed} from 'vue'import {useRoute,useRouter} from 'vue-router'import {useAllDataStore} from '../stores/index.js'const router = useRouter()const store = useAllDataStore()const tags = computed(()=>store.$state.tags)const route = useRoute()const handleMenu = (tag) => {router.push(tag.name)store.selectMenu(tag)}const handleClose = (tag,index) => {store.updateMenu(tag)if(index === store.$state.tags.length){store.selectMenu(tags.value[index-1])router.push(tags.value[index-1].name)}else{store.selectMenu(tags.value[index])router.push(tags.value[index].name)}}</script><style lang="scss" scoped>.tags{margin:20px 0 0 20px;}el-tag{margin-right:10px;}</style>

在store/index.js中添加内容

export const useAllDataStore = defineStore('allData', {state:() => {return {isCollapse: true,tags:[{path:'/home',name:'home',label:'首页',icon:'home',}],currentMenu:null,}},actions: {selectMenu(val){if(val.name === "home"){this.currentMenu =null;}else{this.currentMenu = val// console.log()let index = this.tags.findIndex((item)=> item.name === val.name);index === -1 ? this.tags.push(val) : "";}},updateMenu(tag){let index =this.tags.findIndex((item) => item.name === tag.name)this.tags.splice(index,1)},

搭建登陆页面动态添加路由有两个账号账号一admin密码123456与账号二oner密码123456

请添加图片描述

<template><div class="body-login"><el-form :model="loginForm" class="login-container"><h1>欢迎登陆</h1><el-form-item><el-input type="input" placeholder="请输入账号"v-model="loginForm.username"></el-input></el-form-item><el-form-item><el-input type="input" placeholder="请输入密码"v-model="loginForm.password"></el-input></el-form-item><el-form-item><el-button type="primary" @click="handleLogin"> 登陆</el-button></el-form-item></el-form></div></template><script setup>import {reactive,getCurrentInstance} from 'vue'import {useAllDataStore} from '../stores/index.js'import {useRouter} from 'vue-router'const loginForm = reactive({username:'',password:'',})const {proxy} = getCurrentInstance()const store = useAllDataStore()const router = useRouter()const handleLogin = async () => {const res = await proxy.$api.getMenu(loginForm)store.updateMenuList(res.menuList)store.$state.token = res.tokenstore.addMenu(router)router.push('/home')}</script><style lang="scss" scoped>.body-login{width:100%;height:100%;background-image:url("../assets/images/background.png");background-size:100%;overflow:hidden;}.login-container{width:400px;background-color:#fff;border:1px solid #eaeaea;border-radius:15px;padding:35px 35px 15px 35px;box-shadow:0 0 25px #cacaca;margin:250px auto;h1{text-align:center;margin-bottom:20px;color:#505450;}:deep(.el-form-item__content){justify-content:center;}}</style>

更新store/index.js代码

import { defineStore } from 'pinia'
export const useAllDataStore = defineStore('allData', {state:() => {return {isCollapse: true,tags:[{path:'/home',name:'home',label:'首页',icon:'home',}],currentMenu:null,menuList:[],token:"",routerList:[],}},actions: {selectMenu(val){if(val.name === "home"){this.currentMenu =null;}else{this.currentMenu = val// console.log()let index = this.tags.findIndex((item)=> item.name === val.name);index === -1 ? this.tags.push(val) : "";}},updateMenu(tag){let index =this.tags.findIndex((item) => item.name === tag.name)this.tags.splice(index,1)},updateMenuList(val){this.menuList =val;},//动态添加路由addMenu(router,type){const menu = this.menuListconst module = import.meta.glob("../views/**/*.vue");const routeArr = [];menu.forEach((item)=>{if(item.children){item.children.forEach((val) => {let url = `../views/${val.url}.vue`;val.component = module[url];routeArr.push(...item.children);})}else{let url = `../views/${item.url}.vue`;item.component = module[url];routeArr.push(item)}})this.routerList= [];let routers = router.getRoutes()routers.map((item) => {if(item.name === 'Main' || item.name ==="Login"){return ;}else{router.removeRoute(item.name)}})routeArr.forEach((item) => {this.routerList.push(router.addRoute("Main",item))})// this.routerList= [];// let routers = router.getRoutes()// routers.map((item) => {// if(item.name === 'main' || item.name ==="login"){ return ;}else{// router.removeRoute(item.name)// }// })},clean(){this.routerList.forEach((item) => {if(item) item()})this.$reset()}},})
