Javascript将人类时间转换为时间戳 [英] Javascript Converting human time to timestamp
问题描述
使用javascript,如何将人造时间字符串(例如Wed Jun 20 19:20:44 +0000 2012)转换为时间戳记值,如1338821992?
Using javascript, How can I convert a "human time" string like "Wed Jun 20 19:20:44 +0000 2012" into a timestamp value like "1338821992"?
推荐答案
只需创建一个 Date
对象,并执行 .getTime()
或使用 Date.parse()
:
Just create a Date
object from it and do .getTime()
or use Date.parse()
:
var d = new Date("Wed Jun 20 19:20:44 +0000 2012");
d.getTime(); //returns 1340220044000
//OR
Date.parse("Wed Jun 20 19:20:44 +0000 2012"); //returns 1340220044000
如果您的人造时间字符串的格式为Date构造函数了解(您发布的示例)。
Works great if your "human time" string is in a format that the Date constructor understands (which the example you posted is).
编辑
实现你可能意味着一个Unix时间戳,它是从时代开始的秒数(不像ms时间戳的ms)。在这种情况下,只需将JS时间戳划分为 1000
:
Realized you may mean a Unix timestamp, which is seconds passed since the epoch (not ms like JS timestamps). In that case simply divide the JS timestamp by 1000
:
//if you want to truncate ms instead of rounding just use Math.floor()
Math.round(Date.parse("Wed Jun 20 19:20:44 +0000 2012") / 1000); //returns 1340220044
