vue-router 页面切换后保持在页面顶部而不是保持原先的滚动位置的办法

const router = new VueRouter({
  routes: [...],
  scrollBehavior (to, from, savedPosition) {
    // return 期望滚动到哪个的位置
  }
})

{ x: number, y: number }
{ selector: string }

scrollBehavior (to, from, savedPosition) {
  return { x: 0, y: 0 }
}

scrollBehavior (to, from, savedPosition) {
  if (savedPosition) {
    return savedPosition
  } else {
    return { x: 0, y: 0 }
  }
}
