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

login ---username--->main

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 router-link>

Code:

 //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:&#39;&#39;
  }
  },
   template:`
    <p>
     <h1>主页面用户名:{{uName}}
    
   `,
   //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",{
   //保存用户输入的数据
   data:function(){
    return {
     userInput:""
    }
   },
   methods:{
    toMain:function(){
     //跳转到主页面，并将用户输入的名字发送过去
     this.$router.push("/main/"+this.userInput);
     console.log(this.userInput);
    }
   },

    <p>
     <h1>登录页面
     <input type="text" v-model="userInput" placeholder="请输入用户名">

  //配置路由词典
  const myRoutes = [
   {path:"",component:myLogin},
   {path:"/login",component:myLogin},
    //注意冒号,不用/否则会当成地址
   {path:"/main/:myName",component:myMain},
   //没有匹配到任何页面则跳转到notfound页面
   {path:"*",component:NotFound}
  ]
  const myRouter = new VueRouter({
   routes:myRoutes

  new Vue({
   router:myRouter,
   el:"#container",
   data:{
    msg:"Hello VueJs"
   }

// 注意,路由地址
