15.vue中的路由vue-router

vue路由配置:

1.安装

npm install vue-router --save /  cnpm install vue-router --save

2.引入并Vue.use(VueRouter)  (main.js)

import VueRouter from 'vue-router';

Vue.use(VueRouter)

3.配置路由

1.创建组件,引入组件

import Home from './components/Home.vue';
import News from './components/News.vue';

2.定义路由

const routes=[
    {path:'/home',component:Home},
    {path:'/news',component:News},
      {path:'*',redirect:'/home'} //默认路由跳转到首页
]
//注意,这里是routes,而不是routers

3.实例化VueRouter

const router=new VueRouter({

  routes//(缩写)相当于routes:routes

})

4.挂载

new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

5.在根组件中放入

<router-view></router-view>

6.在根组件中可以通过router-link进行路由的跳转

<router-link to="/home">首页</router-link>
<router-link to="/news">新闻</router-link>

代码

1.在main.js中:

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

import VueResource from 'vue-resource';
Vue.use(VueResource)


import VueRouter from 'vue-router';
Vue.use(VueRouter)

// 1.创建组件,导入组件
import Home from './components/Home.vue';
import News from './components/News.vue';

// 2.配置路由
const routes=[
    {path:'/home',component:Home},
    {path:'/news',component:News},
      {path:'*',redirect:'/home'} //默认路由跳转到首页
]
//注意,这里是routes,而不是routers

// 3.实例化VueRouter
const router=new VueRouter({
    routes//(缩写)相当于routers:routers
})

// 4.挂载
new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

// 5.将<router-view></router-view>放在App.vue里面

2.在App.vue中

<template>
  <div id="app">
    <h2>{{msg}}</h2>

    <router-view></router-view>

    <router-link to="/home">首页</router-link>
    <router-link to="/news">新闻</router-link>

  </div>
</template>
<script>

export default {
  name: 'app',
  data () {
    return { 
      msg:'根组件'
    }
  },
  methods:{
  },

}
</script>
<style>

</style>
