vue3 实现列表的无限循环滚动

通过vue3-seamless-scroll实现

安装vue3-seamless-scroll

 npm install vue3-seamless-scroll --save

使用

<!--组件.vue-->
<script setup lang="ts">
import { Vue3SeamlessScroll } from 'vue3-seamless-scroll';
import { ref } from 'vue'
//vue3导入组件是不需要用component注册的
//导入完成后如果项目本身是在运行的记得重新编译项目，不然会报错，如npm run dev
