Vue2集成ElementUI实现左侧菜单导航功能

作者：冉成未来

本文主要记录两个菜单的生成方式,通过在前端router/index.js中直接进行配置,后端返回菜单数据进行对应,可以通过后端返回的菜单数据控制权限,另一种是部门静态导航,然后再拼接动态导航,生成完成页面导航,感兴趣的朋友一起看看吧

简介

在开发后台系统时，通过菜单进行导航是非常重要的一件事情，在前端开发过程中使用vue2+elementui可以快速搭建菜单导航，本文主要记录两个菜单的生成方式，通过在前端router/index.js中直接进行配置，后端返回菜单数据进行对应，可以通过后端返回的菜单数据控制权限；另一种是部门静态导航，然后再拼接动态导航，生成完成页面导航。

静态导航

安装element-ui,vue-router,vuex

npm install elementui --S
npm install vue-router@3 --S
npm install vuex --S

编写router/index.js

router/index.js

import Vue from 'vue';
import Router from 'vue-router';
Vue.use(Router);
const router = new Router({
  routes: [
    {
      path: '/',
      name: 'Home',
      component: () => import('@/views/Home.vue'),
      children: [
        {
          path: '/index',
          name: 'Index',
          component: () => import('@/views/Index.vue'),
        },
        {
          path: '/documents/note',
          name: 'NoteManagement',
          component: () => import('@/views/NoteManagement.vue'),
        },
        {
          path: '/documents/file',
          name: 'FileManagement',
          component: () => import('@/views/FileManagement.vue'),
        },
        {
          path: '/documents/newMarkdown',
          name: 'NewDocument',
          component: () => import('@/components/RichTextEditor.vue'), // 新增路由指向RichTextEditor.vue
        },
        {
          path: '/documents/newWord',
          name: 'NewWord',
          component: () => import('@/components/WordEditor.vue'),
        },
        {
          path: '/documents/newExcel',
          name: 'NewExcel',
          component: () => import('@/components/ExcelEditor.vue'),
        },
        {
          path: '/system/user',
          name: 'UserManagement',
          component: () => import('@/views/UserManagement.vue'),
        },
        {
          path: '/system/menu',
          name: 'MenuManagement',
          component: () => import('@/views/MenuManagement.vue'),
        },
        {
          path: '/system/role',
          name: 'RoleManagement',
          component: () => import('@/views/RoleManagement.vue'),
        },
        {
          path: 'system/company',
          name: 'CompanyManagement',
          component: () => import('@/views/CompanyManagement.vue'),
        },
        {
          path: '/system/dept',
          name: 'DeptManagement',
          component: () => import('@/views/DeptManagement.vue'),
        },
        {
          path: '/target',
          name: 'TargetManagement',
          component: () => import('@/views/TargetManage.vue'),
        },
        {
          path: '/targetTask',
          name: 'TargetTask',
          component: () => import('@/views/TargetTask.vue'), // 新增路由指向MonthTask.vue
        },
        {
          path: '/dayTask',
          name: 'DayTask',
          component: () => import('@/views/DayTask.vue'), // 新增路由指向DayTask.vue
        }
      ]
    },
    {
      path: '/login',
      name: 'Login',
      component: () => import('@/views/Login.vue'),
    },
    {
      path: '/register',
      name: 'Register',
      component: () => import('@/views/Register.vue'), // 更新注册路由
    },
  ],
});
// 导航守卫
// 使用 router.beforeEach 注册一个全局前置守卫，判断用户是否登陆
router.beforeEach((to, from, next) => {
  if (to.path === '/login') {
    next();
  } else {
    let token = localStorage.getItem('Authorization');
    if (token === null || token === '') {
      next('/login');
    } else {
      next();
    }
  }
});
export default router;

main.js中引入elementui,router

main.js

import Vue from 'vue'
import App from './App.vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import store from './store'
import router from './router/index'
// import mavonEditor from 'mavon-editor'
// import 'mavon-editor/dist/css/index.css';
// import mermaidItMarkdown from 'mermaid-it-markdown'
// mavonEditor.mavonEditor.getMarkdownIt().use(mermaidItMarkdown)
// Vue.use(mavonEditor)
Vue.config.productionTip = false
Vue.use(ElementUI)
new Vue({
  store,
  router,
  render: h => h(App),
}).$mount('#app')

编写左侧导航

 <!-- 第二部分：导航栏和内容显示区域 -->
    <div class="main-content">
      <el-menu
        :default-active="activeMenu"
        @select="handleMenuSelect"
        background-color="#545c64"
        text-color="#fff"
        active-text-color="#ffd04b"
        :collapse="isCollapse"
      >
        <el-menu-item
          v-for="item in filteredMenuItems"
          :key="item.menuPath"
          :index="item.menuPath"
        >
          <i :class="item.menuIcon"></i>
          <span slot="title">{{ item.menuName }}</span>
        </el-menu-item>
        <el-submenu
          v-for="item in menuItemsWithChildren"
          :key="item.menuPath"
          :index="item.menuPath"
        >
          <template #title>
            <i :class="item.menuIcon"></i>
            <span slot="title">{{ item.menuName }}</span>
          </template>
          <el-menu-item
            v-for="child in item.children"
            :key="child.menuPath"
            :index="child.menuPath"
          >
            <i :class="child.menuIcon"></i>
            <span slot="title">{{ child.menuName }}</span>
          </el-menu-item>
        </el-submenu>
      </el-menu>
		//路由出口
      <div class="content">
        <router-view></router-view>
      </div>
    </div>

返回的菜单数据

菜单数据时根据用户id请求后端菜单权限后返回的菜单数据

动态导航

安装vue-router、elementui步骤与静态导航相同

编写router/index.js

import Vue from "vue";
import VueRouter from "vue-router";
Vue.use(VueRouter);
const constantRoutes = [
    {
        path: "/login",
        name: "Login",
        component: () => import("@/views/Login.vue")
    },
    {
        path: "/home",
        name: "Home",
        component: () => import("@/views/Home.vue"),
        children: []
    },
    // {
    //     path: "*",
    //     name: "NotFound",
    //     component: () => import("@/views/NotFound.vue")
    // },
]
const createRouter = () => new VueRouter({
    mode: "hash",
    routes: constantRoutes
})
const router = createRouter();
//路由重置方法
export function resetRouter() {
    const newRouter = createRouter();
    router.matcher = newRouter.matcher; // 重置路由
}
//动态加载路由方法
export const addDynamicRoutes = (menus) => {
  debugger;
  const routes = [];
  //1.转换菜单为路由配置
  const asyncRoutes = coverMenusToRoutes1(routes,menus);
  //2. 添加嵌套路由到Home
  asyncRoutes.forEach(route => {
    // debugger;
    // if (route.name !== '') {
    //   router.addRoute("Home", route);
    // }
    router.addRoute("Home", route);
  });
}
//菜单转换路由方法
const coverMenusToRoutes = (menus) => {
  if (!menus) return [];
  const routes = [];
  menus.forEach(menu => {
    const route = {
      path: menu.path,
      name: menu.path.slice(1),
      meta: {title: menu.name,icon: menu.icon},
      component: resolveComponent(menu.component),
    };
    if (menu.children && menu.children.length > 0) {
      route.children = coverMenusToRoutes(menu.children);
    }
    routes.push(route);
  })
  return routes;
}
const coverMenusToRoutes1 = (routes,menus) => {
  if (!menus) return [];
  // const routes = [];
  menus.forEach(menu => {
    if (menu.component.length > 0){
      const route = {
        path: menu.path,
        name: menu.path.slice(1),
        meta: {title: menu.name,icon: menu.icon},
        component: resolveComponent(menu.component),
      };
      routes.push(route);
    }
    if (menu.children && menu.children.length > 0) {
      coverMenusToRoutes1(routes,menu.children);
    }
  })
  return routes;
}
//动态解析组件路由
function resolveComponent(component) {
  if (!component) return undefined;
  return () => import(`@/views/${component}`);
}
// 导航守卫
// 使用 router.beforeEach 注册一个全局前置守卫，判断用户是否登陆
router.beforeEach((to, from, next) => {
    if (to.path === '/login') {
      next();
    } else {
      let token = localStorage.getItem('token');
      if (token === null || token === '') {
        next('/login');
      } else {
        next();
      }
    }
  });
export default router;

动态导航需要特别注意路径问题，如果路径不正确会导致菜单无法正常显示，因为在项目中返回的菜单数据时树形结构，在处理菜单数据时如果按树形结构嵌套再添加到Home路由的children列表中，菜单无法正常的显示，后面修改了处理逻辑，把有组件的菜单添加到Home路由的children列表后，菜单可以正常显示，需要特别注意

左侧菜单

通过for循环生成

<template>
  <el-menu
    :default-active="defaultActive"
    class="el-menu"
    @open="handleOpen"
    @close="handleClose"
    @select="handleSelect"
    :collapse="isCollapse"
    background-color="#545c64"
    text-color="#fff"
    active-text-color="#ffd04b"
  >
    <span><i :class="collapseClass" @click="changeMenu"></i></span>
    <template v-for="item in menuList">
      <el-submenu
        v-if="item.children && item.children.length"
        :index="item.path"
        :key="item.id"
      >
        <template slot="title">
          <i :class="item.icon"></i>
          <span slot="title">{{ item.name }}</span>
        </template>
        <template v-for="child in item.children">
          <el-submenu v-if="child.children && child.children.length" :index="child.path" :key="child.id">
            <template slot="title">
              <i :class="child.icon"></i>
              <span slot="title">{{child.name}}</span>
            </template>
            <el-menu-item v-for="ch in child.children" :index="ch.path" :key="ch.id">
              <i :class="ch.icon"></i>
              <span slot="title">{{ch.name}}</span>
            </el-menu-item>
          </el-submenu>
          <!-- v-for="child in item.children" -->
          <el-menu-item v-else
            :index="child.path"
            :key="child.id"
          >
            <i :class="child.icon"></i>
            <span slot="title">{{ child.name }}</span>
          </el-menu-item>
        </template>
      </el-submenu>
      <el-menu-item v-else :index="item.path" :key="item.id">
        <i :class="item.icon"></i>
        <span slot="title">{{ item.name }}</span>
      </el-menu-item>
    </template>
  </el-menu>
</template>
<script>
export default {
  data() {
    return {
      collapseClass: "el-icon-s-fold",
      isCollapse: false,
      defaultActive: "1-4-1",
      menuList: [],
    };
  },
  mounted() {
    //获取动态菜单
    this.createMenuList();
  },
  methods: {
    createMenuList() {
      console.log(this.$store.state.menus);
      this.menuList = this.$store.state.menus;
    },
    handleOpen(key, keyPath) {
      console.log(key, keyPath);
    },
    handleClose(key, keyPath) {
      console.log(key, keyPath);
    },
    changeMenu() {
      this.isCollapse = !this.isCollapse;
      if (this.isCollapse) {
        this.collapseClass = "el-icon-s-unfold";
      } else {
        this.collapseClass = "el-icon-s-fold";
      }
    },
    handleSelect(index) {
      this.activeMenu = index;
      if (this.$route.path !== index) {
        // 检查当前路径是否与目标路径相同
        this.$router.push(index);
      }
    },
  },
};
</script>
<style>
.el-menu:not(.el-menu--collapse) {
  width: 220px;
  /* height: 100vh; */
  overflow: hidden;
}
.el-menu {
  width: 60px;
  /* height: 100vh; */
  overflow: hidden;
}
</style>

通过for循环+递归生成

菜单生成子组件

<template>
  <el-menu
    :default-active="defaultActive"
    class="el-menu"
    @open="handleOpen"
    @close="handleClose"
    @select="handleSelect"
    :collapse="isCollapse"
    background-color="#545c64"
    text-color="#fff"
    active-text-color="#ffd04b"
  >
    <template v-for="item in menuList">
      <el-submenu v-if="item.children && item.children.length" :index="item.path" :key="item.id">
      <template slot="title">
        <i :class="item.icon"></i>
        <span slot="title">{{item.name}}</span>
      </template>
      <!-- 递归调用 -->
      <AsideMenu :menuList="item.children"></AsideMenu>
    </el-submenu>
    <el-menu-item v-else :index="item.path" :key="item.id">
        <i :class="item.icon"></i>
        <span slot="title">{{item.name}}</span>
    </el-menu-item>
    </template>
  </el-menu>
</template>
<script>
export default {
  name: "AsideMenu", //name必须要有，要和递归调用的名称保持一致
  components: {
  },
  props: {
    menuList: [],
    // eslint-disable-next-line vue/require-prop-type-constructor
    isCollapse: false,
  },
  data() {
    return {
      // collapseClass: "el-icon-s-fold",
      // isCollapse: false,
      defaultActive: "1-4-1",
    };
  },
  methods: {
    handleOpen(key, keyPath) {
      console.log(key, keyPath);
    },
    handleClose(key, keyPath) {
      console.log(key, keyPath);
    },
    handleSelect(index) {
      debugger;
      this.activeMenu = index;
      console.log(index);
      console.log(this.$route);
      console.log(this.$router.getRoutes());
      if (this.$route.path !== index) {
        // 检查当前路径是否与目标路径相同
        this.$router.push(index);
      }
    },
  },
};
</script>
<style>
.el-menu:not(.el-menu--collapse) {
  width: 220px;
  /* height: 100vh; */
  overflow: hidden;
  border-right: none; /* 隐藏右侧的边框 */
}
.el-menu {
  width: 60px;
  /* height: 100vh; */
  overflow: hidden;
  border-right: none;
}
</style>

子组件名称是必须要有的，递归调用时按照名称进行递归调用。在这个项目中子组件名称为：AsideMenu，递归调用时使用 AsideMenu来引用自身

调用菜单生成的父组件

<template>
  <div class="sidebar">
    <span><i :class="collapseClass" @click="changeMenu"></i></span>
    <!-- 调用菜单生成组件 -->
     <aside-menu :menuList="menuList" :isCollapse="isCollapse"  />
  </div>
</template>
<script>
import AsideMenu from '@/components/AsideMenu.vue';
export default {
  components: {
    AsideMenu
  },
  data() {
    return {
      collapseClass: "el-icon-s-fold",
      isCollapse: false,
      menuList: []
    };
  },
  mounted() {
    //获取动态菜单
    this.createMenuList();
  },
  methods: {
    createMenuList() {
      console.log(this.$store.state.menus);
      this.menuList = this.$store.state.menus;
    },
    changeMenu() {
      this.isCollapse = !this.isCollapse;
      if (this.isCollapse) {
        this.collapseClass = "el-icon-s-unfold";
      } else {
        this.collapseClass = "el-icon-s-fold";
      }
    },
  }
};
</script>
<style scoped>
.sidebar {
    /* border: 1px solid red; */
    background-color:#545c64;
}
</style>

store/index.js

使用vuex保存用户id,token,菜单列表，权限信息，角色信息

import Vue from "vue";
import vuex from "vuex";
Vue.use(vuex);
const store = new vuex.Store({
    state: {
        //用户id
        userId: {},
        //用户token
        token: "",
        //用户角色
        role: "",
        //用户权限
        permission: "",
        //用户菜单
        menus: [],
        //用户路由
    },
    getters: {
        //获取用户id
        getUserId(state) {
            return state.userId;
        },
        //获取用户token
        getToken(state) {
            return state.token;
        },
        //获取用户角色
        getRole(state) {
            return state.role;
        },
        //获取用户权限
        getPermission(state) {
            return state.permission;
       },
        //获取用户菜单
        getMenus(state) {
            return state.menus;
        },
    },
    mutations: {
        //设置用户id
        setUserId(state, userId) {
            state.userId = userId;
            localStorage.setItem("userId", userId);
        },
        //设置用户token
        setToken(state, token) {
            state.token = token;
            localStorage.setItem("token", token);
        },
        //设置用户角色
        setRole(state, role) {
            state.role = role;
        },
        //设置用户权限
        setPermission(state, permission) {
            state.permission = permission;
        },
        //设置用户菜单
        setMenus(state, menus) {
            state.menus = menus;
            localStorage.setItem("menus", menus);
        },
    }
})
export default store;

main.js中引入store

import Vue from 'vue'
import App from './App.vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import router from './router'
import store from './store'
Vue.use(ElementUI)
Vue.config.productionTip = false
new Vue({
    store,
    router,
    render: h => h(App),
}).$mount('#app')

登录页面代码

登录页面存储用户信息、菜单信息、并动态加载路由

<!-- eslint-disable vue/multi-word-component-names -->
<template>
  <el-row type="flex" justify="center" align="middle" style="height: 100vh;">
    <el-col :xs="24" :sm="12" :md="8" :lg="6">

总结

项目开发过程中动态菜单生成、动态路由的正确配置是困难点。

动态菜单的递归调用

递归调用最主要的是对自身的调用，要保持名称和调用自身组件的一致性。

动态路由

动态路由要注意路径问题，不要因为菜单返回树形结构，后期处理的路由也是树形结构，造成子路由里面多层嵌套，无法正常渲染菜单。

记录菜单处理的另外一种方式

MenuTreeOne.vue

  <div class="custom-menu-tree">
    <template v-for="item in menuList">
      <el-submenu
        v-if="item.children && item.children.length"
        :index="item.path"
        :key="item.id"
      >
        <template slot="title">
          <i :class="item.icon"></i>
          <span slot="title">{{ item.name }}</span>
        </template>
        <!-- 递归调用 -->
        <AsideMenuOne :menuList="item.children"></AsideMenuOne>
      </el-submenu>
      <el-menu-item v-else :index="item.path" :key="item.id">
        <i :class="item.icon"></i>
        <span slot="title">{{ item.name }}</span>
      </el-menu-item>
    </template>
  </div>
