Question

代码假设用给定的开始日期和结束日期之间的日期填充数组。我正在使用Node.js.

var startDate = moment(startDay);
var endDate = moment(endDay);
var datesBetween = [];

var startingMoment = startDate;


while(startingMoment <= endDate) {
    datesBetween.push(startingMoment);
    startingMoment.add(1, 'days');
}

console.log(datesBetween);

Answer 1

每次迭代都需要创建一个新对象，否则每次都会将相同的对象引用推送到数组中。它们都将以最后日期结束，因为它是完全相同的对象

每次都可以使用moment.clone()克隆对象

var startDay = new Date(2018,1,1);
var endDay = new Date(2018,1,4);

var startDate = moment(startDay);
var endDate = moment(endDay);
var datesBetween = [];

var startingMoment = startDate;


while(startingMoment <= endDate) {
    datesBetween.push(startingMoment.clone());// clone to add new object
    startingMoment.add(1, 'days');
}

console.log(datesBetween);

Moment.js在javascript，node.js中循环
