vue-router实现组件间的跳转（参数传递）

日期：2020-05-11 栏目：程序人生浏览：次

通过VueRouter来实现组件之间的跳转：参数的传递，具体内容如下

①明确发送方和接收方

②配置接收方的路由地址
{path:'/myTest',component:TestComponent}
-->
{path:'/myTest/:id',component:TestComponent}

③接收方获取传递来的数据
this.$route.params.id

④跳转的时候，发送参数
this.$router.push('/myTest/20')
<router-link :to="'/myTest'+id">跳转</router-link>

代码：

  <!--指定容器 -->
  <router-view></router-view>
 </div>
 <script>
 //创建主页面组件
  var myMain = Vue.component("main-component",{
   //保存登录传递过来的数据
   data:function(){
  return {
   uName:''
  }
  },
   template:`
    <div>
     <h1>主页面用户名:{{uName}}</h1>
    </div>
   `,
   //挂载该组件时自动拿到数据
   beforeMount:function(){
    //接收参数
    console.log(this.$route.params);
    this.uName = this.$route.params.myName ;
   }
  })
  //创建登录页面组件
  var myLogin = Vue.component("login-component",{

    }
   },
