The refresh parameters of the following methods will not be lost

1. name + params

Routing configuration (need to be configured as a dynamic routing form, the original direct parameter passing cannot be used)

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'home',
      component: HomeView,
    },
    {
      path: '/about/:id',
      name: 'about',
      component: () => import('../views/AboutView.vue'),
    },
  ],
})

export default router

Component A

<script>
import { useRouter } from 'vue-router'

export default {
  name: 'Home',
  setup() {
    const router = useRouter()

    const toAbout = () => {
      router.push({
        name: 'about',
        params: {
          id: 100,
        },
      })
    }

    return {
      toAbout,
    }
  },
}
</script>

<template>
  <main>
    <button @click="toAbout">to About</button>
  </main>
</template>

  },
}
</script>

<template>
  <div class="about">
