推荐答案

最简单的方法是将它们转换为Date对象.但是，由于您使用的日期格式为dd/mm/yyyy，因此它实际上不会起作用. (默认情况下，Date使用ISO 8601格式-yyyy-mm-dd.因此，您需要将格式转换为javascript可以理解的格式.

The easiest way is to convert them to Date objects. However, since you're using a date with the dd/mm/yyyy format it won't really work. (By default Date uses the ISO 8601 format - yyyy-mm-dd. So you need to convert the format to something javascript can understand.

// convert to a parseable date string:
var dateStrA = "28/12/2013 16:20:22".replace( /(\d{2})\/(\d{2})\/(\d{4})/, "$2/$1/$3");
var dateStrB = "28/12/2013 16:20:11".replace( /(\d{2})\/(\d{2})\/(\d{4})/, "$2/$1/$3");

// now you can compare them using:
new Date(dateStrA) > new Date(dateStrB);

有点混乱，但是可以解决问题.

A bit messy, but does the trick.

请注意，使用等号(例如===)进行比较将不适用于Date对象.您还可以使用Date.compare()或强制转换为数字，或在日期调用.getDate()

Beware that comparing using equals, such as === will not work on Date objects. You can also use Date.compare() or casting to numbers or call .getDate() on the date
