JavaScript从开始日期开始计算年数和天数 [英] JavaScript calculate years and days from start date

问题描述

我有日期，当有人出生时，我需要使用JavaScript或jQuery等来计算出生日期后的几年。所以结果可以是20年89天。

我需要与维基百科的功能与年龄相同的结果，因为它需要闰年在帐户和什么不。到目前为止，我有代码可以工作，但在某些情况下会导致1天的错误。我的功能是：

  function DateDiff（date1，date2）{
 var res =（（date1.getTime -  date2.getTime（））/ 1000/60/60/24）-offset_d; 
 var full_days = Math.floor（res / 365.25）; 
 var f1 = Math.round（（res％365.25））
 return full_days +years，+ f1 +days;感谢您的帮助，我在这么做几天。

解决方案
你可以自己滚动...但我会强烈推荐一些类似 Moment.js 。它是一个实体图书馆，已被证明在这个领域计算数学。它只有4k，所以我认为你也将罚款。 
 
I have date when someone is born, and I need to calculate with JavaScript or jQuery or so, how many years, days since birth date, until now.

So result can be like 20 years, 89 days.

I need to have same results as Wikipedia does with their function of "age in years", as it takes leap years in account and what not. So far I got code that works, but in some cases makes mistake of 1 day. My function is:
function DateDiff(date1, date2){
var res=((date1.getTime() - date2.getTime())/1000/60/60/24)-offset_d;
var full_days=Math.floor(res/365.25);
var f1=Math.round((res%365.25))
return  full_days + " years, " +f1 +  " days" ; }
Thanks for your help, I am doing this for days.
解决方案
You could roll your own... but I would highly recommend something like Moment.js. It is a solid library that has been proven in the field for calculating Math like this. It is only 4k, so I think you will be fine on size also.
