  • 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>
