vue实现抖音时间转盘

本文实例为大家分享了vue实现抖音时间转盘的具体代码，供大家参考，具体内容如下

做了一个抖音时间转盘，还挺简单的，可能我做的很粗糙

用vue做的 才160行代码。

其实很简单 只是大部分人被这个圆给迷惑了

这个圆就是用简单css3就能做 通过rotate来修改计算就能展示出来了。

然后贴代码。

<template>
 <div class="main">
  <div class="timeBox">
   <div class="yearBox box">{{year}}</div>
   <div class="dayBox box" :style="'transform: rotate('+(360/day.length)*curDay+'deg)'">

      :key="i"
      :style="'transform: rotate('+(-360/day.length) * (i+1) +'deg);transform-origin: -100% 50% 0px;margin-left:150px;margin-top:90px'"
     >{{v}}</li>
    </ul>
   </div>
   <div class="hourBox box" :style="'transform: rotate('+(-360/hour.length)*curHour+'deg)'">
