Vue之vue-router实现路由

1、安装路由插件

npm install --save vue-router

2、在components目录下编写两个vue组件，home.vue和about.vue

<template>
  <div>
    <h1>about</h1>
    <p>{{aboutMsg}}</p>
  </div>
</template>
<script>
  export default {
    data () {
      return {
        aboutMsg: '我是about组件'
      }
    }
  }
</script>

<template>
  <div>
    <h1>home</h1>
    <p>{{msg}}</p>
  </div>
</template>
<script>
  export default {
    data () {
      return {
        msg: "我是home 组件"
      }
    }
  }
</script>

3、在src目录下面创建router.js文件

import Vue from "vue";
import VueRouter from "vue-router";

// 引入组件
import home from "./components/home.vue";
import about from "./components/about.vue";

// 要告诉 vue 使用 vueRouter
Vue.use(VueRouter);

const routes = [
  {
    path:"/home",
    component: home
  },
  {
    path: "/about",
    component: about
  }
]

var router =  new VueRouter({
  routes
})
export default router;

4、在main.js中添加一下几行

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import  router from './router.js'
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>',

})

5、在App.vue引用组件

<template>
  <div id="app">
    <img src="./assets/logo.png">
<!--    <HelloWorld/>-->
    <br/>
    <header>
      <!-- router-link 定义点击后导航到哪个路径下 -->
      <router-link to="/home">Home</router-link>
      <router-link to="/about">About</router-link>
    </header>
    <!-- 对应的组件内容渲染到router-view中 -->
    <router-view></router-view>
  </div>
</template>

<script>
import HelloWorld from './components/HelloWorld'
import MyVue from  './components/MyVue'
export default {name: 'App',
  components: {HelloWorld,
    MyVue
}  //组件注册

}
</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;
}
</style>
