如何解析moment.js日期对象

Question

I am looking to diff the duration in months and days for 2 dates. I having trouble accessing the properties of the object I get back from moment.js.

I can't seem to access the properties of the Duration._data object.

var x = moment(); //todays date
var y = moment("2015-12-1"); // an earlier date
var duration = moment.duration(x.diff(y));
console.log("diff: ", duration);

returns:

diff:  
Duration {_isValid: true, _milliseconds: 106742243043, _days: 0, _months: 0, _data: {…}, …}
_data:
days: 17
hours: 10
milliseconds: 43
minutes: 37
months: 4
seconds: 23
years: 3

Was hoping to get the months and days props, using duration._data.days for example. But I get the error message:

Property '_data' does not exist on type 'Duration'

Answer 1

Use the range , Luke:

var x = moment(); //todays date
var y = moment("2015-12-1"); // an earlier date
var duration = moment.duration(x.diff(y));
const range = moment.range(y, x);
const days = range.diff('days');
console.log("diff: ", days); // gives the number of days

Answer 2

You can simply use duration setter like months() , days() etc

Here a live sample:

 var x = moment(); //todays date var y = moment("2015-12-1", 'YYYY-M-D'); // an earlier date var duration = moment.duration(x.diff(y)); console.log("diff: ", duration.months(), duration.days());

If you want to add the format() method to duration have a look at moment-duration-format plug-in.

Answer 3

var a = moment(); //todays date
var b = moment("2015-12-1"); // an earlier date
var years = a.diff(b, 'year');
b.add(years, 'years');

var months = a.diff(b, 'months');
b.add(months, 'months');

var days = a.diff(b, 'days');

console.log(years + ' years ' + months + ' months ' + days + ' days');

Answer 4

I always use this function to get the the difference in dates.

  const availableTime = moment(endDate);
  const timeDifference = availableTime.diff(moment(startDate));
  return moment.duration(timeDifference);

You can then:

duration.days()
duration.minutes()

Etc..
