如何将毫秒转换为日期和时间? [英] How to convert milliseconds to date and time?

问题描述

我知道这个问题已经被问过很多次了，但是我无法将给定的毫秒数转换为日期和时间.

I know this question has been asked and answered many times, but I could not convert a given milliseconds to date and time.

我有以下代码:

var date = '1475235770601';
var d = new Date(date);
var ds = d.toLocaleString();
alert(ds);
console.log(ds);

运行此命令时，我会在控制台和警报中看到无效的日期.

When I run this I see Invalid Date in console as well as in alert.

但是当我在此处粘贴毫秒时，它会以本地日期和时间的格式很好地转换为Fri Sep 30 2016 17:12:50 .

But when I paste the milliseconds here, it converts fine in the format in local date and time as Fri Sep 30 2016 17:12:50.

实际上我想以09/30/16 17:12:50格式转换.

Actually I want to convert in in the format 09/30/16 17:12:50.

推荐答案

Date的构造方法使用数字，而不是字符串.要么直接输入:

Date's constructor takes a number, not a string. Either feed it in directly:

date = 1475235770601; // Note the lack of quotes making it a number

或者，如果您已经有一个字符串，则将其显式转换:

Or, if you already have a string, convert it explicitly:

date = parseInt(date);
