jquery:如何从日期对象中获取 hh:mm:ss?

问题描述

我怎样才能从日期对象中得到这个 hh:mm:ss?

How can I get this hh:mm:ss from date object?

var d = new Date(); // for now
datetext = d.getHours()+":"+d.getMinutes()+":"+d.getSeconds();

有时我会在下面得到这个结果，

I get this result below sometimes,

12:10:1

应该是

12:10:01

我认为这也会发生在小时和分钟上.

I assume this happens to the hour and minute as well.

所以我在追求这个

01:01:01

不是这个 1:1:1

推荐答案

Solution - (tl;dr version)

datetext = d.toTimeString().split(' ')[0]

说明:

toTimeString 返回完整时间.我们按空间分割它以仅获取时间分量，然后取第一个有用的值.:)

toTimeString returns the complete time.We split it by space to get the time component only, then take the first value which is of use. :)

完整流程:

d = new Date();
// d is "Sun Oct 13 2013 20:32:01 GMT+0530 (India Standard Time)"
datetext = d.toTimeString();
// datestring is "20:32:01 GMT+0530 (India Standard Time)"
// Split with ' ' and we get: ["20:32:01", "GMT+0530", "(India", "Standard", "Time)"]
// Take the first value from array :)
datetext = datetext.split(' ')[0];

注意:这不需要您包含任何外部文件或库，因此执行所需的时间会更快.

Note: This does not require you to include any external files or libraries hence time required for execution would be faster.
