复制1份需要无限滚动的列表，当滚动到第一个列表的结尾处（第二个列表的开始处时），立刻替换位移到初始位置（x=0）由于当时场景与刚开始的场景完全相同，就实现了无缝滚动
<template>
<div>
<div class="scroll-temp">
<div class="temp-box" ref="temp">
<div v-for="v in 5" :key="v + ‘1‘" class="li">
{{ "name" + v }} 当前温度：<span :class="v.ts">{{ v }}℃</span>
湿度：<span :class="v.hs">{{ v }}%</span>
</div>
<div v-for="v in 5" :key="v + ‘2‘" class="li">
{{ "name" + v }} 当前温度：<span :class="v.ts">{{ v }}℃</span>
湿度：<span :class="v.hs">{{ v }}%</span>
