vue-router 的使用。

src outerindex.js

// 配置路由相关信息
import VueRouter from 'vue-router'
import Vue from 'vue'
import Home  from "../components/Home"
import About from "../components/About"
import User from "../components/User";


// 1 通过vue.use(插件) 安装插件
Vue.use(VueRouter)

// 2 创建VueRouter对象
const routes = [
  {
    path: '/',
    redirect:'home'
  },
  {
    path:'/home',
    component:Home
  },
  {
    path:'/about',
    component:About
  },
  {
    path:'/user/:userId/:abc',
    component:User
  }
]
const router = new VueRouter({
  //routes 不是routers
  routes,
  mode:'history'
})

// 3 将router对象传入到vue实例中
export default router

srcApp.vue

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <router-link to="/home" tag="button" replace >首页</router-link>
    <router-link to="/about" replace>关于</router-link>
    <router-link v-bind:to="'/user/'+userid+'/'+abc" >我的</router-link>
    {{userId}}
    {{$route.params.abc}}

    <router-view></router-view>
  </div>
</template>

<script>
export default {
  name: 'App',
  data(){
    return{
      userid:'张三',
      abc:'傻叉'
    }
  },
  computed:{
    userId(){
      return this.$route.params.userId
    }
  }
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
  .router-link-active{
    color: #42b983;
  }
</style>

srcmain.js

import Vue from 'vue'
import App from './App'
import router from './router'

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

效果
