因此,我正在尝试将 UTC 时间以短格式转换为客户端本地时间。我正在使用以下代码:

var date = new Date(call.Timestamp);
date.toLocaleString()

我在屏幕上得到这样的输出:

2012 年 9 月 13 日星期四 14:33:15 GMT+1000(澳大利亚东部标准时间)

我想要做的是将它转换为日期对象以显示短格式:dd/mm/yyyy hh:mm:ss 或 mm/dd/yyyy hh:mm:ss 取决于它们所在的时区. 有没有一种标准的方法可以在 javascript 中做到这一点?有谁知道可以为我做这个的库包?

我也试过:

date.toLocaleDateString() + ' ' + date.toLocaleTimeString()

但日期字符串仍然输出:“Thursday, September 13, 2012”而不是

在 JavaScript 中使用日期一直是一件令人头疼的事情。到目前为止,我发现最好的一个库是Sugar.js

SugarDate使用一些非常强大且富有表现力的方法来扩展该对象,用于创建和操作日期。我认为Date.create()仅此一项就可以满足您的需求。它是 Date 构造函数的一个更好的版本,所以它仍然会返回一个 Date 对象。它需要两个选项参数。一个用于语言环境,一个用于 UTC。

在这里您可以看到方法的详细信息。

javascriptDate没有任何格式化日期字符串的方法。您必须使用获取日期、月份、年份、小时数等的方法自己完成。

参考:https ://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date#Methods_2

例如:

var date = new Date();
var d = [date.getDate(), date.getMonth()+1, date.getFullYear()];
var t = [date.getHours(), date.getMinutes(), date.getSeconds()];
var dateStr = d.join("/") + " " + t.join(":");

否则,您可以使用任何库,例如 @ethagnawl 建议的库,它支持许多格式选项。

jQuery date foramtting 仅适用于 jQuery UI datepicker,你可以在这里找到一个演示http://jqueryui.com/demos/datepicker/date-formats.html

很久以前,我发现了这个有用的脚本,并从那时起就使用它:
