在javascript中将时间格式更改为24小时

问题描述

我的时间格式为:12/16/2011 3:49:37 PM，我通过以下方式获取此格式:

I have a time format like: 12/16/2011 3:49:37 PM and I got this format by:

var newDate = new Date(timeFromat);
timeFormat = newDate.toLocaleString();

我的实际格式是格林尼治标准时间(GMT)，我使用上面的代码将其转换为凉亭时间.

My actual format was GMT and I converted it to my bowers time by using the code above.

，我想将其更改为24小时制，因此我希望将此日期更改为:12/16/2011 15:49:37，我想使用javascript.

and I want to change it to 24h time format so I want this date to be changed like: 12/16/2011 15:49:37 and I want to do it in javascript.

那是我所做的

var firstPartOftimeFormat = timeFormat.substring(0,9);
var secondPartOftimeFormat = timeFormat.substring(10,20);

，但当日期格式为:3/16/2011时，则不起作用.但以下部分有效.

but it does not work when the date format is like: 3/16/2011. but the following part works.

var time = $("#starttime").val();
var hours = Number(secondPartOftimeFormat.match(/^(\d+)/)[1]);
var minutes = Number(secondPartOftimeFormat.match(/:(\d+)/)[1]);
var AMPM = secondPartOftimeFormat.match(/\s(.*)$/)[1];
if(AMPM == "PM" && hours<12) hours = hours+12;
if(AMPM == "AM" && hours==12) hours = hours-12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if(hours<10) sHours = "0" + sHours;
if(minutes<10) sMinutes = "0" + sMinutes;
alert(sHours + ":" + sMinutes);

您可以建议其他方法吗?

Can you suggest other approach?

谢谢

推荐答案

使用 dateObj.toLocaleString([locales [，options]])

选项1 -使用语言环境

var date = new Date();
console.log(date.toLocaleString('en-GB'));

选项2 -使用选项

var options = { hour12: false };
console.log(date.toLocaleString('en-US', options));
