使用moment.js格式化日期

Question

I'm using the moment.js library to format dates in the format MM DD, YYYY . What am I missing?

Code below:

import moment from 'moment';

var dateStr = '2015-10-19T13:33:52.140Z';

var d = new Date(dateStr); // Mon Oct 19 2015 13:33:52 GMT+0000 (GMT)

console.log( moment(d, "MM DD, YYYY").toDate() ) // Still outputs Mon Oct 19 2015 13:33:52 GMT+0000 (GMT)

Answer 1

There is no need tou use JavaScript Date to parse your string, just use moment(string) (because your input is in ISO 8001 format), then you have to use format() :

 var dateStr = '2015-10-19T13:33:52.140Z'; console.log( moment(dateStr).format("MM DD, YYYY"))

Answer 2

只需使用Format方法

moment(dateStr).format("MM DD, YYYY");
