I'd suggest just using the Javascript Date object for this purpose.
我建议为此目的仅使用 Javascript Date 对象。
var d = new Date();
var time = d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds();
Edit: I just came across the method below, which covers formatting issues such as the one mike-samuel mentioned and is cleaner:
编辑：我刚刚遇到了下面的方法，它涵盖了格式问题，例如提到的 Mike-samuel 并且更清晰：
var time = d.toLocaleTimeString();
回答by Mike Samuel
function formatTimeOfDay(millisSinceEpoch) {
var secondsSinceEpoch = (millisSinceEpoch / 1000) | 0;
var secondsInDay = ((secondsSinceEpoch % 86400) + 86400) % 86400;
var seconds = secondsInDay % 60;
var minutes = ((secondsInDay / 60) | 0) % 60;
var hours = (secondsInDay / 3600) | 0;
return hours + (minutes < 10 ? ":0" : ":")
+ minutes + (seconds < 10 ? ":0" : ":")
+ seconds;
}

new Date().toString().split(' ')[4]
or
或者
new Date().toString().match(/\d{2}:\d{2}:\d{2}/)[0]
The toStringmethod is basically an alias for toLocaleStringin most implementations. This will return the time in the user's timezone as opposed to assuming UTC by using milliseconds if you use getTime(if you use getMillisecondsyou should be OK) or toUTCString.
该toString方法基本上是toLocaleString大多数实现中的别名。这将返回用户时区中的时间，而不是假设 UTC 使用毫秒getTime（如果使用的getMilliseconds话）或toUTCString.

Where can I find documentation on formatting a date in JavaScript?

jQuery doesn't have date formatting. You can roll your own with the JavaScript Dateobject, or you can use a library that does it for you. DateJSis one such library, which provides a rich set of formatting, parsing, and manipulation functionality. However, it hasn't been maintained in years. momentjsis under active development.
jQuery 没有日期格式。您可以使用 JavaScriptDate对象创建自己的对象，也可以使用为您执行此操作的库。DateJS就是这样一个库，它提供了一组丰富的格式化、解析和操作功能。然而，多年来一直没有得到维护。momentjs正在积极开发中。

I'm way late to this, but thought i'd just throw this little snippet out there for the masses. This is something I use just to get a quick localized timestamp. It's pretty clean and handy.
我迟到了，但我想我只是把这个小片段扔给大众。这是我用来快速获取本地化时间戳的东西。它非常干净和方便。
function getStamp() {
var d = new Date();
var mm = d.getMilliseconds(), hh = d.getHours(),
MM = d.getMinutes(), ss = d.getSeconds();
return (hh < 10 ? "0" : "") + hh + (MM < 10 ? ":0" : ":") + MM + (ss < 10 ? ":0" : ":") + ss + ":" + mm;
};
