vue router 路由传参

第一种 params 

{
      path: '/son1',
      name:"son1",
      component: son1,
}

为路由命名 name:"son1",

在路由跳转时，指定命名路由，传参

1
 <router-link  :to="{name:'son1',params:{id:2,name:'winter',age:18}}" tag="li">首页</router-link>

或2

this.$router.push({
   name:"son1",
    params:{
       id:2,
       name:'winter',
       age:18
      }
});

组件页面 接收展示

<p>{{"我是params传来的id"+" "+$route.params.id}}</p>
<p>{{"我是params传来的name"+" "+$route.params.name}}</p>
<p>{{"我是params传来的age"+" "+$route.params.age}}</p>

query 传参与params 类似，

1 query要用path来引入，params要用name来引入，接收参数类似，分别是​​this.$route.query.name​​​和​​this.$route.params.name​​

​​2 ​​query在浏览器地址栏中显示参数，params则不显示

3    通过路由params传值，刷新页面数据消失会报错

 

第二种  props

配置路由

props: {
          id: 1234,
          userName: "Winter"
},

页面接收

export default {
        name: "son1",
        props: ['id', 'userName']
    }

页面展示

<h5>{{"我是props传来的id"+" "+id}}</h5>
<h5>{{"我是props传来的userName"+" "+userName}}</h5>

第三种 meta

路由配置

meta: {
         title: "首页",
         show: true
},

页面接收展示

<h3 v-show="this.$route.meta.show">{{this.$route.meta.title}}</h3>
