一、路由鏈路

二、實現步驟

準備二級路由下的.vue文件

配置子路由

router/index.js

import { createRouter,createWebHistory } from "vue-router";//導入組件
import LoginVue from '@/views/Login.vue'
import LayoutVue from '@/views/Layout.vue';
import ArticleCategoryVue from '@/views/article/ArticleCategory.vue'
import ArticleManageVue from '@/views/article/ArticleManage.vue'
import UserAvatarVue from '@/views/user/UserAvatar.vue'
import UserInfoVue from '@/views/user/UserInfo.vue'
import UserResetPasswordVue from '@/views/user/UserResetPassword.vue'//定義路由關系
const routes = [{path: '/login',component: LoginVue},{path: '/',component: LayoutVue,//重定向redirect: '/article/manage',//子路由children: [{ path: '/article/category', component: ArticleCategoryVue },{ path: '/article/manage', component: ArticleManageVue },{ path: '/user/info', component: UserInfoVue },{ path: '/user/avatar', component: UserAvatarVue },{ path: '/user/password', component: UserResetPasswordVue },]}
]//創建路由器
const router = createRouter({history: createWebHistory(),routes:routes
})//導出路由
export default router

聲明router-view標簽

Layout.vue

<router-view></router-view>

為菜單項 el-menu-item 設置index屬性，設置點擊后的路由路徑
