You don't need an external library to do this. See this doc linkfor the forms of date that JavaScript can process normally.

您不需要外部库来执行此操作。有关JavaScript 可以正常处理的日期形式,请参阅此文档链接

For a specific solution to your question:

对于您的问题的具体解决方案:

var date = new Date("04/11/13" + " " + "17:02:30");
date.toISOString();
>> "2013-04-11T21:02:30.000Z"

See this MDN pagefor more info on the Date object.

The best way to do this in AngularJS is with a filter. You bind to the dateTime, and then filter it with the date filter.

在 AngularJS 中执行此操作的最佳方法是使用过滤器。您绑定到日期时间,然后使用日期过滤器对其进行过滤。

<span>{{myDate | date:yyyy-MM-ddThh:mm:sss}}</span>

Or in your controller you say:

或者在你的控制器中你说:

$filter('date')(date[, format])
