Remove seconds from toLocaleTimeString
提问by mate64
The Date.prototype.toLocaleTimeString()method returns a string with a language sensitive representation of the time portion of this date. It is available for modern browsers.
该Date.prototype.toLocaleTimeString()方法返回一个字符串，该字符串具有该日期时间部分的语言敏感表示。它适用于现代浏览器。
Unfortunately, the native function is not ableto prevent the output of seconds. By default, it outputs a time format like hh:mm:ssor hh:mm AM/PMetc.
不幸的是，本机函数无法阻止seconds的输出。默认情况下，它输出类似hh:mm:ss或hh:mm AM/PM等的时间格式。
second: The representation of the second. Possible values are "
numeric", "2-digit".
second：第二个的表示。可能的值为“
numeric”、“2-digit”。

This means, that you can not use something like {second: false}.
这意味着，您不能使用类似{second: false}.
I'm looking for a simple stupidsolution, to remove the secondsfrom a hh:mm:ssformatted string.
我正在寻找一个简单的愚蠢解决方案，从格式化的字符串中删除秒数hh:mm:ss。
var date = new Date();
var time = date.toLocaleTimeString(navigator.language, {hour: '2-digit', minute:'2-digit'});
console.log(time); // 15:24:07
This regular expressions don'twork:
这正则表达式不工作：
time.replace(/:\d\d( |$)/,'');
time.replace(/(\d{2}:\d{2})(?::\d{2})?(?:am|pm)?/);

You can use:
您可以使用：
var time = date.toLocaleTimeString(navigator.language, {hour: '2-digit', minute:'2-digit'})
.replace(/(:\d{2}| [AP]M)$/, "");
btw Google Chromereturns
顺便说一句Google Chrome返回
new Date().toLocaleTimeString(navigator.language, {hour: '2-digit', minute:'2-digit'});
as "12:40 PM"
作为 "12:40 PM"

Just to add another possible combination to achieve this:
只是添加另一种可能的组合来实现这一点：
(new Date()).toLocaleTimeString().match(/\d{2}:\d{2}|[AMP]+/g).join(' ')
