路由跳转--编程式导航

news2024/9/21 4:29:12

简介

除了使用创建 a 标签来定义导航链接，我们还可以通过编程式导航实现导航。所谓编程式导航指的是不通过router-link跳转，而是借助 router 的实例，通过代码的方式跳转。

示例：

App.vue

<template>
  <div id="app">
    <button @click="toHome">Home</button>
    <button @click="toNews">News</button>
    <button @click="toDetails">Details</button>
    <br>
    <router-view></router-view>
  </div>
</template>
<script>
  export default {
    methods: {
      toHome () {
        this.$router.push('/home')
      },
      toNews () {
        this.$router.push({
          path: '/news',
          query: { name: 'zhangsan' }   //query方式传参
        })
      },
      toDetails () {
        this.$router.push({
          name: 'Details',
          params: { nid: 1001 }       //params方式传参
        })
      }
    }
  }
</script>

Home.vue

<template>
  <div>
    <h2>Home</h2>
  </div>
</template>

News.vue

<template>
  <div>
    <h2>News</h2>
    {{this.$route.query}}  <!—获取query传递过来的数据/ get传值 -->
  </div>
</template>

Details.vue

<template>
  <div>
    <h2>Details</h2>
    {{this.$route.params.nid}}   <!—获取params传递过来的数据 -->
  </div>
</template>

router目录下的index.js

const routes = [{
  path: '/home',
  component: () => import('../views/Home')
}, {
  path: '/news',
  component: () => import('../views/News') // 懒加载
}, {
  path: '/details/:nid',
  name: 'Details',
  component: () => import('../views/Details') // 懒加载
}]
