从零开始学VUE之VueRouter(动态路由)

<template>
  <div>
    <h2>this is {{userId}}!</h2>
  </div>
</template>

<script>
export default {
  name: "User",
  computed:{
    userId(){
      // 获取传递的参数 这里是route 注意
      return this.$route.params.userId;
    }
  }
}
</script>

<style scoped>

</style>

{
  path:'/user/:userId', // 传递参数的占位符
    name: 'user',
      component:user
}

<router-link :to="/user/+userId" replace>用户</router-link>
