Javascript返回两个日期之间的天数，小时，分钟，秒数 [英] Javascript return number of days,hours,minutes,seconds between two dates

问题描述

有没有人可以链接我一些教程，我可以找到如何在2个unix datetimes之间的JavaScript中返回天，小时，分钟，秒数？

我有：

  var date_now = unixtimestamp; 
 var date_future = unixtimestamp; 
  

我想返回（live）从date_now剩下多少天，几小时，几分钟到date_future。

解决方案

只需弄清楚差异（不要忘记JS时间戳实际上是以毫秒为单位），分解该值：

  //获取时间之间的总秒数
 var delta = Math.abs（date_future  -  date_now ）/ 1000; 
 
 //计算（减）整天
 var days = Math.floor（delta / 86400）; 
 delta  -  = days * 86400; 
 
 //计算（减）整个小时
 var hours = Math.floor（delta / 3600）％24; 
 delta  -  =小时* 3600; 
 
 //计算（并减去）整个分钟
 var minutes = Math.floor（delta / 60）％60; 
 delta  -  = minutes * 60; 
 
 //剩下的是秒
 var seconds = delta％60; //理论上不需要模块
  

编辑只是意识到原来的代码返回了总的小时数等，而不是整天计算剩余的小时数。

Does anyone can link me to some tutorial where I can find out how to return days , hours , minutes, seconds in javascript between 2 unix datetimes?

I have:

var date_now = unixtimestamp;
var date_future = unixtimestamp;

I would like to return (live) how many days,hours,minutes,seconds left from the date_now to the date_future.

解决方案

Just figure out the difference in seconds (don't forget JS timestamps are actually measured in milliseconds) and decompose that value:

// get total seconds between the times
var delta = Math.abs(date_future - date_now) / 1000;

// calculate (and subtract) whole days
var days = Math.floor(delta / 86400);
delta -= days * 86400;

// calculate (and subtract) whole hours
var hours = Math.floor(delta / 3600) % 24;
delta -= hours * 3600;

// calculate (and subtract) whole minutes
var minutes = Math.floor(delta / 60) % 60;
delta -= minutes * 60;

// what's left is seconds
var seconds = delta % 60;  // in theory the modulus is not required

EDIT code adjusted because I just realised that the original code returned the total number of hours, etc, not the number of hours left after counting whole days.
