下面的逻辑将在几个月内取得差异

(endDate.getFullYear()*12+endDate.getMonth())-(startDate.getFullYear()*12+startDate.getMonth())

#这是我写的一段很好的代码，用于获取天数和月份 从给定日期开始

把你的手

/** * Date a end day * Date b start day * @param DateA Date @param DateB Date * @returns Date difference */ function getDateDifference(dateA, DateB, type = 'month') { const END_DAY = new Date(dateA) const START_DAY = new Date(DateB) let calculatedDateBy let returnDateDiff if (type === 'month') { const startMonth = START_DAY.getMonth() const endMonth = END_DAY.getMonth() calculatedDateBy = startMonth - endMonth returnDateDiff = Math.abs( calculatedDateBy + 12 * (START_DAY.getFullYear() - END_DAY.getFullYear()) ) } else { calculatedDateBy = Math.abs(START_DAY - END_DAY) returnDateDiff = Math.ceil(calculatedDateBy / (1000 * 60 * 60 * 24)) } const out = document.getElementById('output') out.innerText = returnDateDiff return returnDateDiff } // Gets number of days from given dates /* getDateDifference('2022-03-31','2022-04-08','day') */ // Get number of months from given dates getDateDifference('2021-12-02','2022-04-08','month') <div id="output"> </div>

JavaScript中两个日期的月份差异:

 start_date = new Date(year, month, day); //Create start date object by passing appropiate argument
 end_date = new Date(new Date(year, month, day)

从start_date到end_date的总月份:

 total_months = (end_date.getFullYear() - start_date.getFullYear())*12 + (end_date.getMonth() - start_date.getMonth())

这应该可以正常工作:

function monthDiff(d1, d2) {
    var months;
    months = (d2.getFullYear() - d1.getFullYear()) * 12;
    months += d2.getMonth() - d1.getMonth();
    return months;
}

getMonthDiff(d1, d2) {
    var year1 = dt1.getFullYear();
    var year2 = dt2.getFullYear();
    var month1 = dt1.getMonth();
    var month2 = dt2.getMonth();
    var day1 = dt1.getDate();
    var day2 = dt2.getDate();
    var months = month2 - month1;
    var years = year2 -year1
    days = day2 - day1;
    if (days < 0) {
        months -= 1;
    }
    if (months < 0) {
        months += 12;
    }
    return months + years*!2;
}

一种方法是编写一个使用JODA库的简单Java Web服务(REST/JSON)

http://joda-time.sourceforge.net/faq.html#datediff

计算两个日期之间的差异，并从javascript调用该服务。

这假设您的后端是Java。
