This article mainly introduces how to set up the navigation bar, sidebar for public pages related knowledge, detailed and easy to understand, simple and fast operation, with a certain reference value, I believe everyone read this vue how to set up the navigation bar, sidebar for public pages articles will have some harvest, let's take a look at it together.

First, the project structure is as follows:

想要让导航栏、侧边栏变为公共页面，则要在App.vue页面中加入。假设已经有了Header.vue和Left.vue，这里就不贴出来了，App.vue代码如下：

import header from './components/Header.vue';import left from './components/Left.vue'; export default{ components: { headerNav: header, left: left }}

此时运行会发现，所有的页面都被加上了这两个公共页面，而实际场景中，我们往往希望登录页是不需要导航栏和侧边栏的，那么就需要规避掉登录页。

这时，就可以采用keep-alive结合$route.meta来实现这个功能。keep-alive 是 Vue 内置的一个组件，可以使被包含的组件保留状态，或避免重新渲染。$route.meta则可以选择让需要的页面才展示。修改App.vue，如下：

import header from './components/Header.vue';import left from './components/Left.vue'; export default{ components: { headerNav: header, left: left }}

index.js代码如下：

import Vue from 'vue'import Router from 'vue-router'import HelloWorld from '@/components/HelloWorld' import Login from '@/views/Login'import index from '@/views/index'import versionList from '@/views/versionList' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'login', component: Login, meta: { keepAlive: false } }, { path: '/index', name: 'index', component: index, meta: { keepAlive: true } }, { path: '/versionList', name: 'versionList', component: versionList, meta: { keepAlive: true } }, ]})

通过设置keepAlive的值就可以实现除了登录页不展示公共页面，在其他页面均展示的功能。
