vue中路由传参方式-----router-link 进行页面按钮式路由跳转传参

router中路由配置

分两种方式进行举例：

第一种是params传参，第二种是query传参

 {
   path: 'homeDetails/:id',//params传参
   name:'homeDetails'
   component: () =>import ('@/views/home/homeDetails.vue'),
   //子路由的绝对路径
  },

 {
   path: 'homeDetails/',//query传参
   name:'homeDetails'
   component: () =>import ('@/views/home/homeDetails.vue'),
   //子路由的绝对路径
  },

父组件home点击传参

// params传参
<router-link to="/homeDetails/12345"></router-link>
<router-link to="{name:'homeDetails',params:{id:12345}"></router-link>
//切记名字用name,不能用path

//query传参
<router-link to="/homeDetails?id=12345"></router-link>
<router-link to="{path:'/homeDetails',query:{id:12345}"></router-link>
<router-link to="{name:'homeDetails',query:{id:12345}"></router-link>

子组件homeDetails接受参数

子组件使用this.$route.params.id来接收路由参数

// 子组件使用this.$route.params.id来接收路由参数
<template>
 <div><span>我是从父组件传递过来的id：</span>{{this.$route.params.id}}</div>
  //或
 <div><span>我是从父组件传递过来的id：</span>{{id}}</div>
</template>
<script>
 export default{
   data(){
    id:''
   },
   mounted(){
    this.id = this.$route.params.id  //12345
    this.id = this.$route.query.id  //12345
   }
 } 
</script>
