????????最近在自己搞一個前后端小項目，前端想使用ant-design-vue的layout組件實現(xiàn)動態(tài)導航欄和面包屑，但是網(wǎng)上的資料較少，所以我就自己整合實現(xiàn)了一下，在此記錄分享。

1 準備工作

????????基于一個新建的Vue3項目上實現(xiàn)。

1.1 安裝ant-design-vue

? ? ? ? 官方文檔：Components Overview - Ant Design Vue (antdv.com)

????????安裝：

npm i --save ant-design-vue

????????全局注冊：

import { createApp } from 'vue';
import Antd from 'ant-design-vue';
import App from './App';
import 'ant-design-vue/dist/antd.css';

const app = createApp(App);

app.use(Antd).mount('#app');

1.2 安裝圖標組件包

npm install --save @ant-design/icons-vue

????????main.js中引用并全局注冊

import * as Icons from '@ant-design/icons-vue'
//全局注冊圖標
const icons = Icons
for (const i in icons) {
  app.component(i, icons[i])
}

2 選擇組件

????????如下圖所示，復制組件代碼：

antdesign 導航菜單動態(tài)顯示,vue.js,javascript,前端

3 路由文件

????????router/index.js文件

import { createRouter, createWebHashHistory } from 'vue-router'

const routes = [
  {
    //導航頁
    path: '/layout',
    name: 'layout',
    meta: {
      title: '首頁',
      keepalive: true
    },
    component: () => import('@/views/layout/'),
    children: [
      {
        //歡迎頁
        path: '/layout',
        name: 'welcome',
        meta: {
          title: '首頁',
          keepalive: true
        },
        component: () => import('@/views/welcome/')
      },
      {
        //實時數(shù)據(jù)
        path: '/runtimeData',
        name: 'runtimeData',
        meta: {
          title: '實時數(shù)據(jù)',
          keepalive: true
        },
        component: () => import('@/views/runtimeData/')
      },
      {
        //數(shù)據(jù)分析
        path: '/dataAnalysis',
        name: 'dataAnalysis',
        meta: {
          title: '數(shù)據(jù)分析',
          keepalive: true
        },
        component: () => import('@/views/dataAnalysis/')
      },
      {
        //數(shù)據(jù)處理(增刪改查)
        path: '/dataManage',
        name: 'dataManage',
        meta: {
          title: '數(shù)據(jù)總覽',
          keepalive: true
        },
        component: () => import('@/views/dataManage/')
      },
      {
        //查看用戶信息
        path: '/showUserInfo',
        name: 'showUserInfo',
        meta: {
          title: '查看用戶信息',
          keepalive: true
        },
        component: () => import('@/views/my/showUserInfo.vue')
      },
      {
        //修改用戶信息
        path: '/editUserInfo',
        name: 'editUserInfo',
        meta: {
          title: '修改用戶信息',
          keepalive: true
        },
        component: () => import('@/views/my/editUserInfo.vue')
      },
    ]
  },
  {
    //登錄頁面
    path: '/login',
    name: 'login',
    meta: {
      title: '登錄',
      keepalive: true
    },
    component: () => import('@/views/login/index.vue')
  },

]

const router = createRouter({
  history: createWebHashHistory(),
  routes
})

export default router

4 Vue導航頁面

????????views/layout/index.vue，主要關注標簽a-layout中的內(nèi)容及相關變量

<template>
  <a-layout id="components-layout-demo-custom-trigger" style="min-height: 100vh">
    <a-layout-sider v-model:collapsed="collapsed" collapsible>

????????上面的代碼中將路由文件中的路由表重新寫了一個變量，主要是為了方便，并不是所有頁面路由都要制作導航欄，這樣就不用在router/index.js中添加路由時考慮太多。
