How to pass parameters between vue-router components

This time I will bring you the method of passing parameters between vue-router components. What are the precautions for passing parameters between vue-router components? The following is a practical case, let's take a look.

Use VueRouter to implement jumps between components: parameter transfer, the specific content is as follows

①Clear the sender and receiver

②Configure the

routing address of the receiver{path:'/myTest',component:TestComponent}
-->
{path:'/myTest/:id',component :TestComponent}

③The receiver gets the passed data

this.$route.params.id

④When jumping, send parameters

this.$router.push('/myTest/20')
Jump

Code:

 //创建主页面组件

     <h1>主页面用户名:{{uName}}</h1>

   `,
   //挂载该组件时自动拿到数据
   beforeMount:function(){
    //接收参数
    console.log(this.$route.params);
