Vue.js——路由1

使用路由，首先要下载路由 进入cmd然后层层进入项目

npm install vue-router --save

重新运行一下

npm run dev

准备工作做好了 接下来在main.js中配置一下你的路由信息

// 引入路由
import VueRouter from 'vue-router'
// 引入跳转的目标文件 这里用的都是组件
import Home from './components/Home'
import Menu from './components/Menu'
import About from './components/about/About'

// 使用路由
Vue.use(VueRouter)

// 声明路由信息 start
const routes=[
	{path:'/',component:Home},
	{path:'/menu',component:Menu},
	{path:'/about',component:About},
    {path:'*',redirect:'/'}
]

//或者使用name
const routes=[
	{path:'/',name:"homeLink",component:Home},
	{path:'/menu',name:"menuLink",component:Menu},
	{path:'/about',name:"aboutLink",component:About},
   {path:'*',redirect:'/'}
]
// 初始化路由
const router=new VueRouter({
	routes,
	mode:"history"
})
// 实例化对象中放入配置好的路由
new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

配置好了之后 在App.vue中使用

<router-view></router-view>

在需要跳转的地方 使用 router-link 替换a标签 to替换 href

<router-link to="/" class="nav-link">主页</router-link>
<router-link to="/menu" class="nav-link">菜单</router-link>
<router-link to="/about" class="nav-link">关于我们</router-link>

//或者使用name
<router-link :to="{name:'homeLink'}" class="nav-link">主页</router-link>
<router-link :to="{name:'menuLink'}" class="nav-link">菜单</router-link>
<router-link :to="{name:'aboutLink'}" class="nav-link">关于我们</router-link>

二级路由 添加children

const routes=[
	{path:'/',name:"homeLink",component:Home},
	{path:'/menu',component:Menu},
	{path:'/about',redirect:'/history',component:About,
	  children:[
		{path:'/about/contact',name:"contactLink",component:Contact},
		{path:'/history',name:"historyLink",component:History},
		{path:'/Delivery',name:"deliveryLink",component:Delivery},
		{path:'/orderingGuide',name:"orderingGuideLink",component:OrderingGuide},
	]},
	{path:'*',redirect:'/'}
]
