Vue路由传参的几种方式-案例

router-link 进行页面按钮式路由跳转传参

Router配置

{
   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>//切记之呢个用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.$route.params.id来接收路由参数
<template>
 <div><span>我是从父组件传递过来的id：</span>{{this.$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>

this.$router.push进行编程式路由跳转传参

Router配置

params第一种传参路由配置
{
   path: '/homeDetails/:id',//要传递的参数前面加：
   component: () =>import ('@/views/home/homeDetails.vue')
},


params第二种（name传参）或 query方式的路由配置
{
   path: '/homeDetails',
   name:'homeDetails'
   component: () =>import ('@/views/home/homeDetails.vue')
},

组件home点击传参

// 例如表格中点击表名称跳转新页面需要把id传到新页面使用
<template>
  <el-table :data="tableDatas">
    <el-table-column label="产品名称">
      <template slot-scope="scope" @click="handleClick(scope.row.id)">{{ scope.row.name}}</template>
    </el-table-column>
     ...
  </el-table>
 </template>
 <script>
 export default{
   data(){
    tableDatas:[];//表格数据
   },
   methods:{
    handleClick(id){
      console.log(id) //121345
      this.$router.push({path:`/homeDetails/${id}`}) //params方式传参第一种方式
      this.$router.push({name:'homeDetails',params:{id:id}}) //params方式传参第二种方式
      
      // 或
      this.$router.push({path:`/homeDetails`, query:{id:id}}) // query方式传参
    }
   }
 } 
</script>

组件homeDetails接受参数

// 子组件使用this.$route.params.id来接收路由参数
<template>
 <div><span>这就是我需要的id：</span>{{$route.params.id || $route.query.id}}</div>
  //或
 <div><span>这也是我需要的id：</span>{{id}}</div>
</template>
<script>
 export default{
   data(){
    id:''
   },
   mounted(){
    this.id = this.$route.params.id  //121345  params传参方式接收
    //或
    this.id = this.$route.query.id  //121345  query传参方式接收
   }
 } 
</script>
