JavaScript中以年、月、日为单位的两个日期之间的差异
我已经搜索了4个小时了,还没有找到一个解决方案来获得JavaScript中两个日期(年、月和日)之间的差异,比如:2010年4月10日是3年前,x月和y日前 有很多解决方案,但它们只提供了日、月或年的格式差异,或者它们不正确(意味着不考虑一个月或闰年的实际天数,等等)。真的有那么难吗 我看了一下:JavaScript中以年、月、日为单位的两个日期之间的差异,javascript,date,datediff,Javascript,Date,Datediff,我已经搜索了4个小时了,还没有找到一个解决方案来获得JavaScript中两个日期(年、月和日)之间的差异,比如:2010年4月10日是3年前,x月和y日前 有很多解决方案,但它们只提供了日、月或年的格式差异,或者它们不正确(意味着不考虑一个月或闰年的实际天数,等等)。真的有那么难吗 我看了一下: ->只能输出年、月或日的差值 www.stackoverflow.com->搜索功能 在php中很容易,但不幸的是,我只能在该项目上使用客户端脚本。任何能够做到这一点的库或框架也可以 以下是

//Expected output should be: "1 year, 5 months".
diffDate(new Date('2014-05-10'), new Date('2015-10-10'));
//Expected output should be: "1 year, 4 months, 29 days".
diffDate(new Date('2014-05-10'), new Date('2015-10-09'));
//Expected output should be: "1 year, 3 months, 30 days".
diffDate(new Date('2014-05-10'), new Date('2015-09-09'));
//Expected output should be: "9 months, 27 days".
diffDate(new Date('2014-05-10'), new Date('2015-03-09'));
//Expected output should be: "1 year, 9 months, 28 days".
diffDate(new Date('2014-05-10'), new Date('2016-03-09'));
//Expected output should be: "1 year, 10 months, 1 days".
diffDate(new Date('2014-05-10'), new Date('2016-03-11'));
我会亲自使用,真的很方便。具体地说,看看time.js文件:一些数学问题已经解决了
在Javascript中,您可以将一个日期对象与另一个日期对象相减,得到它们之间的差值,单位为毫秒。从该结果中,您可以提取所需的其他部分(天、月等)
例如:
var a = new Date(2010, 10, 1);
var b = new Date(2010, 9, 1);
var c = a - b; // c equals 2674800000,
// the amount of milisseconds between September 1, 2010
// and August 1, 2010.
现在你可以得到你想要的任何零件。例如,两个日期之间经过了多少天:
var days = (a - b) / (60 * 60 * 24 * 1000);
// 60 * 60 * 24 * 1000 is the amount of milisseconds in a day.
// the variable days now equals 30.958333333333332.
差不多31天了。然后,您可以将30天的时间四舍五入,并使用剩余的时间来计算小时数、分钟数等。您需要多精确?如果您确实需要考虑普通年份和闰年,以及月与月之间的天数差,那么您必须编写更高级的内容,但对于基本和粗略的计算,这应该可以做到:
today = new Date()
past = new Date(2010,05,01) // remember this is equivalent to 06 01 2010
//dates in js are counted from 0, so 05 is june
function calcDate(date1,date2) {
var diff = Math.floor(date1.getTime() - date2.getTime());
var day = 1000 * 60 * 60 * 24;
var days = Math.floor(diff/day);
var months = Math.floor(days/31);
var years = Math.floor(months/12);
var message = date2.toDateString();
message += " was "
message += days + " days "
message += months + " months "
message += years + " years ago \n"
return message
}
a = calcDate(today,past)
console.log(a) // returns Tue Jun 01 2010 was 1143 days 36 months 3 years ago
请记住,这是不精确的,为了精确计算日期,必须有一个日历,知道一年是否是闰年,而且我计算月数的方法只是近似的
但是你可以很容易地改进它 为了方便快捷,我不久前写了这个函数。它以良好的格式返回两个日期之间的差异。可以随意使用它(在webkit上测试)
