vue--routing configuration

Using routing, one exit can jump to two pages.

Effect


implementation steps:

Step 0, install routing

When installing routing, pay attention to your vue version. If you run npm install vue-routerthe command directly, the latest version will be downloaded. The latest version is suitable for vue3.0. I am using version 2.7, so execute the npm install --save vue-router@3command.
If you need to uninstall the previous route, you can do so npm uninstall vue-router.

The following is directly written in main.js :

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

Vue.config.productionTip = false

//1. 安装   引入路由
import VueRouter from 'vue-router'
Vue.use(VueRouter)

//2. 定义路由组件
import Home from "./views/Home.vue"
import news from "./views/news.vue"

//3.定义路由- 配置路由走向
const routes = [
  {
    
    
    path: "/", //页面的路径
    component: Home  //去哪个页面
  },
  {
    
    
    path: "/news", //页面的路径
    component: news  //去哪个页面
  }
]

//4. 创建router实例，然后传“routes”配置
const router = new VueRouter({
    
    
  //routes : routes
  routes
})

//5. 创建和挂载根实例
new Vue({
    
    
  router, //router: router
  render: h => h(App),
}).$mount('#app')

Before this, I created two pages. How to display them without pages:
Note that the pages here are in the src directory. The name can be defined by yourself, usually called 'view'.


Finally, it can be displayed directly in App.vue. .

<template>
  <div id="app">
      app
      <!-- 显示导航 -->
      <div>
        <router-link to="/">首页</router-link> | 
        <router-link to="/news">新闻页✌</router-link>
      </div>
      <!-- 显示路由出口 -->
      <router-view></router-view>
  </div>
</template>

<script>

export default {
      
      
  name: 'App',
  components: {
      
      
  }
}
</script>

<style lang="less">
#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>
