js部分

<script setup>
import { useRouter } from 'vue-router'
const route = useRouter()
const jumpHandler = path => {
  // route.replace(path)
  route.push(path+`?name=Hachiman&age=20&id=123`)

 html页面使用路由传来的参数

<template>
  <h2>
    home组件 传递来的参数{{ $route.query }}
  </h2>
</template>

 获取router跳转id

<template>
  <h2>用户id: {{ $route.params.id }}</h2>
  <button @click="backHandler">返回</button>
</template>
<script setup>
import { useRoute, useRouter, onBeforeRouteUpdate } from 'vue-router'
const route = useRoute()
console.log(route.params.id)
// 获取 route 跳转 id
onBeforeRouteUpdate((to, from) => {
  console.log('from:', from.params.id)
  console.log('to:', to.params.id)
})
const router = useRouter()
const backHandler = () => {
  // 后退 和 前进
  // router.back()
  // router.forward()

  // go(1) => forward()
  // go(-1) => back()
  router.go(-1)
}
</script>

获取 路由跳转错误地址

<template>
    <div class="notFound">路径{{ $route.params.pathMatch }}不正确</div>
</template>
<style>
.notFound{
  font-size: 30px;
  color: red;
}
</style>
