replace

App.vue

<template>
  <h1>hello world</h1>
  <div>
      <!-- replace 不保存历史记录 -->
    <router-link replace to="/">login</router-link>
    <router-link replace style="margin-left: 10px;" to="/reg">reg</router-link>

    <button style="margin-left: 10px;" @click="toPage('/')">Login</button>
      <button style="margin-left: 10px;" @click="toPage('/reg')">Reg</button>
  </div>
  <hr>
  <router-view></router-view>
</template>

<script setup lang="ts">
import { useRouter } from 'vue-router';
const router = useRouter();
const toPage = (path: string) => {
  // 同样，replace 不保存历史记录
  router.replace(path)
}
</script>

<style scoped></style>

反复点两个 router-link 或者两个按钮，左右箭头仍未不可点击状态，说明无残留历史记录。
