午夜重置javascript倒计时

Question

我有倒计时的页面，我想在每个午夜重置倒计时。我想重置每个午夜，从23小时59分59秒开始，da.y你能帮我吗？这里是html，css和javascript。现在它被手动固定到一个日期，但这对我不好。那可能吗？

<div class="wrapper"> 
    <div class="clock"> 
     <div class="column days"> 
      <div class="timer" id="days"></div> 
      <div class="text">DAYS</div> 
     </div> 
     <div class="timer days">:</div> 
     <div class="column"> 
      <div class="timer" id="hours"></div> 
      <div class="text">ORE</div> 
     </div> 
     <div class="timer">:</div> 
     <div class="column"> 
      <div class="timer" id="minutes"></div> 
      <div class="text">MINUTE</div> 
     </div> 
     <div class="timer">:</div> 
     <div class="column"> 
      <div class="timer" id="seconds"></div> 
      <div class="text">SECUNDE</div> 
     </div> 
    </div> 
</div>

编辑您的提琴在这里https://jsfiddle.net/zd82dav7/1/

增加了一个新的Date对象，并用它作为结束日期：

endDate: dT.getFullYear() + "-" + prependZero(dT.getMonth() + 1) + "-" + prependZero(dT.getDate()) + ' 23:59',

现在使用当前日期和将结束时间设置为当天的23:59。这意味着当时钟经过午夜时，它将启动一个新的计数器23小时59分钟。不知道结束时间是否支持秒...没有检查。但是你总是可以将它添加到字符串中。
