vue后台管理系统 vue3+vite+pinia+elementui+axios下

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-column

v-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-pagination

class="pager"

background

layout="prev, pager,next"

size="small"

:total="config.total"

@current-change="handleChange"

>

</el-pagination>

</div>

<el-dialog

v-model="dialogVisible"

:title="action === 'add' ? '新增用户' : '编辑用户'"

width="35%"

:before-close="handleClose"

>

<!--需要注意的是设置了:inline="true"，

会对el-select的样式造成影响，我们通过给他设置一个class=select-clearn

在css进行处理-->

<el-form :inline="true" :model="formUser" :rules="rules" ref="userForm">

<el-row>

<el-col :span="12">

<el-form-item label="姓名" prop="name">

<el-input v-model="formUser.name" placeholder="请输入姓名" />

</el-form-item>

</el-col>

<el-col :span="12">

<el-form-item label="年龄" prop="age">

<el-input v-model.number="formUser.age" placeholder="请输入年龄" />

</el-form-item>

</el-col>

</el-row>

<el-row>

<el-col :span="12">

<el-form-item class="select-clearn" label="性别" prop="sex">

</el-form-item>

</el-col>

</el-row>

<el-row>

<el-form-item

label="地址"

prop="addr"

<el-input v-model="formUser.addr" placeholder="请输入地址" />

</el-form-item>

</el-row>

<el-row style="justify-content: flex-end">

<el-form-item>

<el-button type="primary" @click="handleCancel">取消</el-button>

<el-button type="primary" @click="onSubmit">确定</el-button>

</el-form-item>

</el-row>

</el-form>

</el-dialog>

</template>


<style lang="scss" scoped>

.user-header{

display:flex;

justify-content: space-between;

}

.table{

position:relative;

height:520px;

.pager{

position:absolute;

right:10px;

bottom:30px;

}

.el-table{

}

</style>

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',

})

},

editUser(params) {

return request({

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(),

sex: Mock.Random.integer(0, 1)

}

  
  

export default {

* @param name, page, limit

*/

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 false

return true

})

return {

}

}

},

//在原来的export default 中添加

  

/**

*/

deleteUser: config => {

const { id } = param2Obj(config.url)

  

if (!id) {

return {

code: -999,

}

} else {

return {

}

}

},

*/

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 = name

u.addr = addr

u.age = age

u.birth = birth

u.sex = sex_num

return 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([

const getUserData = async () => {

let data = await proxy.$api.getUserData(config)

}

const formInline = reactive({

page:1

})

const handleSearch=() => {

getUserData()

const handleDelete =(val) => {

const action =ref('add')

//这个方法之前定义过

//格式化日期，格式化为：1997-01-02这种

const timeFormat = (time) => {

}

  

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") {

}else if(action.value == "edit"){

}

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=true

nextTick(()=>{

//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-tag

v-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
