javascript - 使用 Moment.js 格式化日期

Question

我有一个这种格式的字符串:

var testDate = "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"

我想使用 Moment.js以这种格式获取它 mm/dd/yyyy : 04/12/2013 用于显示。

我试过用这种方法来做，

moment(testDate,'mm/dd/yyyy');

哪个错误并说没有这样的方法叫做replace？我是否以错误的方式处理这个问题？

编辑

我还应该提到，我使用的是 Moment.js 的预打包版本，为 Meteor.js

打包

Object [object Date] has no method 'replace' : The Exact error from the console

Answer 1

moment() 的第二个参数是 parsing format而不是 显示 格式。

为此，您需要 .format() method :

moment(testDate).format('MM/DD/YYYY');

还要注意大小写很重要。对于月份、月份和年份，格式应为大写。
