路由

安装:
script引入方式:

<script src="/path/to/vue.js"></script>
<script src="/path/to/vue-router.js"></script>

npm方式:

npm install vue-router

引用:

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

const router = new Router({
  mode: 'history',
  routes: [
    { path: '/',component: Home    //path路由地址,component组件地址,上面需引入 },
    {path: '/about',name:'路由名称',component: About},//通过name给路由定义名称
   {path: '*',redirect:'/'}//找不到路由地址,跳转到首页
  ]
})

new Vue({
      router 
})    //实例化router 

使用:

<div id="app">
    <ul>
      <li><router-link tag="div" to="/">Hello</router-link></li>
      <li><router-link :to="{name:'路由名称'}">About</router-link></li>
    </ul>
    <router-view></router-view>
  </div>

//router-link标签默认生成的是a标签,可以通过tag属性重新定义,如tag="div"

//:to可以通过路由name进行跳转

跳转

<router-link >第一种</router-link>

function(){
    this.$router.push()    //第二种,可以直接写路径,或者{name:'路由名称'}
}

二级路由创建

import Vue from 'vue'
import App from './App.vue'
import Router from 'vue-router'//引入
Vue.use(Router)
import Hello from './components/Hello'//一级路由
import About from './components/about/About'//一级路由
import Phone from './components/about/Phone'//二级路由
import Email from './components/about/Email'//二级路由

Vue.config.productionTip = false
const router = new Router({
  mode: "history",//去掉域名地址上的#符号
  routes: [
    { path: "/",name:'homeLink', component: Hello },//定义一级路由
    { path: "/about",redirect:'/about/phone', component: About,children:[//通过children设置二级路由,redirect设置默认路由
      {path:"/about/phone",name:'phoneLink',component:Phone},
      {path:"/about/email",name:'emailLink',component:Email}
    ]},
    { path: "*", redirect: "/about" }
  ]
})
new Vue({
  router,//实例化router
  render: h => h(App)
}).$mount('#app')
