如何在vue 3中点击按钮打开一个新页面？

npm install vue-router

<template>
  <div>
    <h1>This is a new page</h1>
  </div>
</template>

<script>
export default {
  name: 'NewPage',
}
</script>

<style scoped>
/* 样式 */
</style>

import { createApp } from 'vue'
import { createRouter, createWebHistory } from 'vue-router'
import App from './App.vue'
import NewPage from './components/NewPage.vue'

const router = createRouter({
  history: createWebHistory(),
  routes: [
    { path: '/', component: App },
    { path: '/newpage', component: NewPage },
  ],
})

const app = createApp(App)
app.use(router)
app.mount('#app')

<template>
  <div>
    <h1>Welcome to Vue App</h1>
    <button @click="goToNewPage">Open New Page</button>
  </div>
</template>

<script>
export default {
  name: 'App',
  methods: {
    goToNewPage() {
      this.$router.push('/newpage')
    }
  }
}
</script>

<style scoped>
/* 样式 */
</style>
