如何在16:00每天晚上重设我的倒计时

我正在为我的网站倒计时工作。我们在每天16:00之前提供当天发货。我需要一个计数器，每天倒数到16点。最终，我会修改代码，使其在周末根本不显示，但现在，我需要的是每天都可以倒计时的东西。 16:00后消失，并从00:00开始重新开始倒计时如何在16:00每天晚上重设我的倒计时

以下是我目前使用的代码。

<?php 
if (new DateTime() < new DateTime("16:00:00")) { 

?> 
<script type="text/javascript"> 

    var CDown = function() { 
     this.state=0;// if initialized 
     this.counts=[];// array holding countdown date objects and id to print to {d:new Date(2013,11,18,18,54,36), id:"countbox1"} 
     this.interval=null;// setInterval object 
    } 

    CDown.prototype = { 
     init: function(){ 
      this.state=1; 
      var self=this; 
      this.interval=window.setInterval(function(){self.tick();}, 1000); 
     }, 
     add: function(date,id){ 
      this.counts.push({d:date,id:id}); 
      this.tick(); 
      if(this.state==0) this.init(); 
     }, 
     expire: function(idxs){ 
      for(var x in idxs) { 
      this.display(this.counts[idxs[x]], "Now!"); 
      this.counts.splice(idxs[x], 1); 
     } 
    }, 
    format: function(r){ 
     var out=""; 
     if(r.d != 0){out += r.d +" "+((r.d==1)?"day":"days")+", ";} 
     if(r.h != 0){out += r.h +" "+((r.h==1)?"hour":"hours")+", ";} 
     out += r.m +" "+((r.m==1)?"min":"mins")+", "; 
     out += r.s +" "+((r.s==1)?"sec":"secs")+", "; 

     return out.substr(0,out.length-2); 
    }, 
    math: function(work){ 
     var y=w=d=h=m=s=ms=0; 

     ms=(""+((work%1000)+1000)).substr(1,3); 
     work=Math.floor(work/1000);//kill the "milliseconds" so just secs 

     y=Math.floor(work/31536000);//years (no leapyear support) 
     w=Math.floor(work/604800);//weeks

     work=work%3600; 

     m=Math.floor(work/60);//minutes

      for(var idx=0,n=this.counts.length; idx<n; ++idx){ 
       cnt=this.counts[idx]; 
       amount=cnt.d.getTime()-now;//calc milliseconds between dates 

       // if time is already past 
       if(amount<0){

       else{

       } 
      } 

      // deal with any expired 
      if(expired.length>0) this.expire(expired); 

      // if no active counts, stop updating 
      if(this.counts.length==0) window.clearTimeout(this.interval); 

     },

    window.onload=function(){

我很抱歉，我不能格式这个正确的，我也不认为它已经粘贴了所有的。我将这个文件放在一个在线文件中并快速分享 –

你的问题在于你必须一直保持打开特定的浏览器标签，因为如果有人关闭浏览器等时间间隔将停止计数。我通常使用一个批次文件重新打开页面，然后使用标准任务计划程序每天运行批处理文件。 – Shilly

为了确保网页访问者看到正确的时间，请使用PHP来计算剩余时间，并将其提供给JavaScript代码（作为函数参数）。否则，访客将根据他们的本地机器时钟（可能与您的公司时钟不同几分钟或几小时）看到一个时间。如果你这样做，确保页面不会被缓存，否则访问者会看到一个过时的剩余时间。 – Bobulous

您可以使用一个cron job将每24小时重置一次变量。

我真的不知道从哪里开始 –

PHP和JavaScript都可用，cron作业和系统变量对于此目的完全没有必要。 – Bobulous

该脚本可以控制此功能，并且不需要cron作业 –

概念在这里测试变量countDownTo更改为当前小时线8，103和109 变化对行的变量分钟133
