format date with moment.js
提问by Warz
I have a string in this format:
我有一个这种格式的字符串：
var testDate = "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
var testDate = "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
I would like to using moment.js get it in this format mm/dd/yyyy : 04/12/2013for display.
我想使用 moment.js 以这种格式获取它以mm/dd/yyyy : 04/12/2013进行显示。
I tried to do it using this method,
我尝试使用这种方法来做到这一点，
moment(testDate,'mm/dd/yyyy');
Which errors and says there is no such method called replace? am i approaching this in the wrong way?
哪个错误并说there is no such method called replace？我是否以错误的方式接近这个？
Edit:
编辑：
I should also mention that i am using a pre packaged version of moment.js, packaged for meteor.js
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

The 2nd argument to moment()is a parsingformatrather than an displayformat.
的第二个参数moment()是解析格式而不是显示格式。
For that, you want the .format()method:
为此，您需要以下.format()方法：
moment(testDate).format('MM/DD/YYYY');
Also note that case does matter. For Month, Day of Month, and Year, the format should be uppercase.
另请注意，大小写确实很重要。对于 Month、Day of Month 和 Year，格式应为大写。

Include moment.js and using the below code you can format your date
包括 moment.js 并使用以下代码可以格式化您的日期
var formatDate= 1399919400000;
var responseDate = moment(formatDate).format('DD/MM/YYYY');
My output is "13/05/2014"
我的输出是“13/05/2014”

moment().format(); // "2019-08-12T17:52:17-05:00" (ISO 8601, no fractional seconds)
moment().format("dddd, MMMM Do YYYY, h:mm:ss a"); // "Monday, August 12th 2019, 5:52:00 pm"
moment().format("ddd, hA"); // "Mon, 5PM"

For fromating output date use format. Second moment argument is for parsing - however if you omit it then you testDatewill cause deprecation warning
对于从输出日期使用format. 第二时刻参数用于解析 - 但是，如果省略它，testDate则会导致弃用警告
Deprecation warning: value provided is not in a recognized RFC2822 or ISO format...
弃用警告：提供的值不是公认的 RFC2822 或 ISO 格式...
var testDate= "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
let s= moment(testDate).format('MM/DD/YYYY');
msg.innerText= s;<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>
<div id="msg"></div>to omit this warning you should provide parsing format
要忽略此警告，您应该提供解析格式
var testDate= "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
let s= moment(testDate, 'ddd MMM D YYYY HH:mm:ss ZZ').format('MM/DD/YYYY');
console.log(s);<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>
