    }
  },
  // 進(jìn)入該路由時(shí)
  activated() {

  },

  // 離開該路由前
  beforeRouteLeave(to, from, next) {

vue3 組合式保存位置

<script setup>
import {onActivated, ref } from "vue";
import {onBeforeRouteLeave} from 'vue-router';

const scrollTop = ref(0)
// 離開該路由前
onBeforeRouteLeave(() => {
 scrollTop.value = document.documentElement.scrollTop || 0
})

 // 進(jìn)入該路由時(shí)
onActivated(() => {
  document.documentElement.scrollTop =  scrollTop.value
})
</script>
