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

问题描述

有没有人可以将我链接到一些教程，在那里我可以找到如何在 2 个 unix 日期时间之间的 javascript 中返回天、小时、分钟、秒?

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?

我有:

var date_now = unixtimestamp;
var date_future = unixtimestamp;

我想返回(实时)从 date_now 到 date_future 还剩多少天、小时、分钟、秒.

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

推荐答案

只需找出秒的差异(别忘了 JS 时间戳实际上是以毫秒为单位测量的)并分解该值:

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 代码进行了调整，因为我刚刚意识到原始代码返回了总小时数等，而不是计算一整天后剩余的小时数.

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.
