使用Moment.js返回值

Question

I'm using some of the date manipulation functions of moment.js such as add days.

import moment from 'moment';

const addDays = (date, days) => {
    return moment(date).add(days, 'd');
}

This seems to work but returns an object. How do I return a simple date value?

Answer 1

Depends on how you want it formatted and what data type.

To get a copy of the native Date object that Moment.js wraps, use the .toDate() function..

return moment(date).add(days, 'd').toDate();

To get a copy as an ISO formatted string..

return moment(date).add(days, 'd').toISOString();

To get a copy as a true string (what I think you want)..

return moment(date).add(days, 'd').toString(); // Sat Apr 30 2016 16:59:46 GMT-0500 return moment(date).add(days, 'd').toString(); // Sat Apr 30 2016 16:59:46 GMT-0500 or return moment(date).add(days, 'd').format(); // 2013-03-10T01:30:00-05:00 return moment(date).add(days, 'd').format(); // 2013-03-10T01:30:00-05:00

To get a copy as a string in a certain format..

return moment(date).add(days, 'd').format('MMMM Do YYYY, h:mm:ss a'); // June 28th 2017, 3:55:57 pm
