javascript - 使用 moment.js 查找日期范围之间的完整周数和天数

Question

我的日期范围是

var currDay = Jan.1
var birthday = Feb.15

我知道找到周数的差异是

currDay.diff(birthday, 'week')

但是，有没有办法找到完整的周数和剩余的天数？

Answer 1

您可以使用 duration .

用这个可以得到年、月(不包括年)和日(不包括年、月)。唯一的问题是周数是使用天数计算的，因此如果您要获得周数，您仍然需要获得天数的余数。

来自 momentjs docs :

Pay attention that unlike the other getters for duration, weeks are counted as a subset of the days, and are not taken off the days count.

注意:如果您想要总周数，请使用 asWeeks() 而不是 weeks()

var currDay = moment("2018-01-01");
var birthday = moment("2018-02-16");

var diff = moment.duration(birthday.diff(currDay));

console.log(diff.months() + " months, " + diff.weeks() + " weeks, " + diff.days()%7 + " days.");

console.log(Math.floor(diff.asWeeks()) + " weeks, " + diff.days()%7 + " days.");
