一、项目介绍

项目使用vue3+vite+element-plus+pinia+router+axios等搭建，每个页面已经完成了对后端api请求的编码，各种交互已经写好，同时通过pinia实现数据同步与通讯，在此基础上实现页面历史导航栏功能，增加了支持多层级顶级菜单联动左侧菜单，左侧菜单由顶部菜单控制，导航栏实现对顶级菜单和左侧菜单的样式同步。

其中菜单可支持动态配置，菜单icon也支持组件化动态配置，这大大提高了框架的灵活度和便捷性。

项目同时采用组件来布局整个框架，左侧+顶部+导航栏+具体页面功能展示容器。

三、项目截图

1.登录页

输入账密登录，登录成功，跳转首页。

2.首页

首页的导航栏是默认的，不可取消。

3.汽车管理

选择顶部菜单，左侧菜单对应展示，同时历史导航栏增加当前页面。

4.汽车信息

各种脚本校验都通过vue3实现，文件上传等，其他页面类似

5.系统管理

系统管理主要作为管理员日常使用的功能，可归纳在此。

 

6.订单管理

 订单管理可作为一个主要的功能模块，可单独分离出来，方便管理。

7.数据统计

 数据统计，一般管理系统都会有此类似模块，可单独归为一个菜单专门管理。

8.个人中心 

可进行个人信息修改和密码修改。

四、源码分析

1.数据存储与同步

主要包含用户登录信息和历史导航栏等数据的存储与同步。历史导航栏的增删改查都有对应的方法，用户登录后，信息也会暂寄存于此，即变量：nowUser

import {defineStore} from 'pinia'
import {CarStatus} from "@/type/dataDefinition";
// @ts-ignore
import {diff} from '@/util/util'export const useStore = defineStore('main', () => {const chosenCarType = ref({nowCarType: "",nowCarTypeId: "",});const chosenCar = ref({id: "",carConfigs: [],});const lastPage = ref(1);const firstPage = ref("/home");const nowUser = reactive({form: {} as any} as any);const search = reactive({form: {} as any} as any);const tagSet = reactive({form: {tagList:[], tag:{label:"首页",value:"/home"}} as any } as any);const subMenu = reactive({form: [] as any} as any);const getLastPage = () => {return lastPage.value;};const setLastPage = (item: number) => {lastPage.value = item;};const addTag = (tag: any) => {if(tag.value === '/'){tag.value = "/home";tag.label = "首页";}if(tagSet.form.tagList.length === 0){tagSet.form.tagList.push({label:"首页",value:"/home"});}tagSet.form.tag = tag;if (tagSet.form.tagList.some((ele:any)  => diff(ele, tag))) return;let saveTag = {};Object.assign(saveTag, tag);tagSet.form.tagList.push(saveTag);};const delTag = (tag:any)=>{tagSet.form.tagList = tagSet.form.tagList.filter((item:any) => {return !diff(item, tag) || item.value === firstPage.value;});};const delOtherTag = ()=>{tagSet.form.tagList = tagSet.form.tagList.filter((item:any) => {if (item.value === tagSet.form.tag.value) {return true;} else if (item.value === firstPage.value) {return true;}});};const delAllTag = ()=>{tagSet.form.tagList = tagSet.form.tagList.filter((item:any) => {if (item.value === firstPage.value) {return true;}});};const clearTag = ()=>{tagSet.form.tagList = [];};return {chosenCarType, chosenCar, lastPage,firstPage, subMenu, getLastPage, setLastPage, nowUser, search,tagSet,addTag,delTag,delOtherTag,delAllTag,clearTag};
}, {persist: true,
})

2.汽车信息
