上面是将Forecast组件作为了Home的子组件使用,现在我们将其作为一个路由组件使用。
在router/index.js路由系统注册路由:
{ path: '/forecast', name: 'Forecast', // route level code-splitting // this generates a separate chunk (about.[hash].js) for this route // which is lazy-loaded when the route is visited. component: () => import(/* webpackChunkName: "about" */ '../components/Forecast.vue') },
app.Vue中更新为:
<template> <div id="nav"> <router-link to="/">Home</router-link> | <router-link to="/about">About</router-link>| <router-link to="/forecast">天气预报</router-link> </div> <router-view/> </template>
1、路由跳转
vue-router提供了2种写法让我们实现页面跳转。
(1)通过router-link来跳转
正如App.Vue中的使用:
<template> <div id="nav"> <router-link to="/">Home</router-link> | <router-link to="/about">About</router-link>| <router-link to="/forecast">天气预报</router-link>| </div> <router-view/> </template>
(2)通过this.$router来跳转
<template> <div id="nav"> <router-link to="/">Home</router-link> | <router-link to="/about">About</router-link>| <router-link to="/forecast">天气预报</router-link>| <a href="" @click.prevent="gohome">Home</a> </div> <router-view/> </template> <script> export default { name: 'App', // 组件名 data(){ return { user:"root", } }, methods:{ gohome(){ // 页面跳转 if(this.user === "root"){ this.$router.push("/"); // ajax页面跳转到指定的路由地址 // this.$router.back(); // 跳转返回上一页 // this.$router.go(-1); // -1相当于back,后退一页 // this.$router.go(1); // 1表示forward,前进一页 } } }, } </script> <style> #app { font-family: Avenir, Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; } #nav { padding: 30px; } #nav a { font-weight: bold; color: #2c3e50; } #nav a.router-link-exact-active { color: #42b983; } </style>
2、传递参数
vue-router提供了2种用于开发中传递参数的方式给我们使用。
(1)路径参数
url地址的路径作为变量,传递参数到下一个页面组件中进行获取使用。
注册路由:
{ path: '/article/:year/:month', name: 'Article', // route level code-splitting // this generates a separate chunk (about.[hash].js) for this route // which is lazy-loaded when the route is visited. component: () => import(/* webpackChunkName: "about" */ '../components/Article.vue') },
创建Article.vue:
<template> <h3> 查询{{year}}年{{month}}的系列文章 </h3> </template> <script> export default { name: "Article", data(){ return { year: 0, month: 0, } }, created() { this.year = this.$route.params.year; this.month = this.$route.params.month; } } </script> <style scoped> </style>
最后在App.Vue中添加:
<router-link to="/article/2000/12">文章列表</router-link>|
(2)查询参数
url地址的查询字符串作为参数,在下一个页面组件中进行获取使用。
注册路由:
{ path: '/article2/', name: 'Article2', // route level code-splitting // this generates a separate chunk (about.[hash].js) for this route // which is lazy-loaded when the route is visited. component: () => import(/* webpackChunkName: "about" */ '../components/Article2.vue') },
创建Article2.vue:
<template> <h3> 查询{{year}}年{{month}}的系列文章 </h3> </template> <script> export default { name: "Article", data(){ return { year: 0, month: 0, } }, created() { this.year = this.$route.query.year this.month = this.$route.query.month } } </script> <style scoped> </style>
最后在App.Vue中添加:
<router-link to="/article2/?year=2008&month=12">文章列表2</router-link>|
