有了孩子之后，对小宝宝的事情会不刻意的增加很多关注，这可能就是做父亲的责任吧。
崽崽的周岁开始倒计时了，但是日子长了，算起来就比较费劲，也容易算错。本想依靠百度，没想到花了一晚竟找不到一款，能够计算宝宝年龄比较准确的软件！失望之余，我决定在工作之余写一个这样的计算小功能。于是就有了以下内容：
新鲜出炉！代码还有很多地方需要优化，甚至还有bug，但是仍然迫不及待的贴出来，跟网友们分享。
第一个计算方式，计算出宝宝从出生到现在的天数、时、分、秒：
//获取出生天数、时、分、秒
function getGrowTime(birthday)
{
var currentTime = Date.parse(new Date());
var myTime = new Date(birthday);
var myTimeStamp = Date.parse(myTime);
var gapSec = (currentTime - myTimeStamp)/1000;
var day = 0;
var hour = 0;
var min = 0;
var sec = 0;
if(gapSec/(60*60*24) > 0)
{
day = (gapSec-gapSec%(60*60*24))/(60*60*24);
gapSec = gapSec%(60*60*24);
if((gapSec/3600) > 0)
{
hour = (gapSec-gapSec%3600)/3600;
gapSec = gapSec%3600;
if((gapSec/60) > 0)
{
min = (gapSec-gapSec%60)/60;
sec = gapSec%60;
} else
{
sec = gapSec;
}
} else
{
if((gapSec/60) > 0)
{
min = (gapSec-gapSec%60)/60;
sec = gapSec%60;
} else
{
sec = gapSec;
}
}
} else
{
if((gapSec/3600) > 0)
{
hour = (gapSec-gapSec%3600)/3600;
gapSec = gapSec%3600;
if((gapSec/60) > 0)
{
min = (gapSec-gapSec%60)/60;
sec = gapSec%60;
} else
{
sec = gapSec;
}
} else
{
if((gapSec/60) > 0)
{
min = (gapSec-gapSec%60)/60;
sec = gapSec%60;
} else
{
sec = gapSec;
}
}
}
var dateStr = (day<10? ("0"+day): day)+"天 " +
(hour<10? ("0"+hour): hour)+"时 " +
(min<10? ("0"+min): min)+"分 " +
(sec<10? ("0"+sec): sec)+"秒";
return dateStr;
}第二个计算方式，计算宝宝从出生到现在的周岁、月、天、时、分、秒，这个很常用：
//获取出生年龄，周岁、月、天、时、分、秒
function getGrowAge(birthday)
{
var now = new Date();
var year = now.getFullYear();
var month = now.getMonth() + 1;
var day = now.getDate();
var hour = now.getHours();
var minute = now.getMinutes();
var second = now.getSeconds();
var myDate = new Date(birthday);
var myYear = myDate.getFullYear();
var myMonth = myDate.getMonth() + 1;
var myDay = myDate.getDate();
var myHour = myDate.getHours();
var myMinute = myDate.getMinutes();
var mySecond = myDate.getSeconds();
var gapSecond = second - mySecond;
if(gapSecond < 0)
{
minute -= 1;
gapSecond = 60 - mySecond + second;
}
var gapMinute = minute - myMinute;
if(gapMinute < 0)
{
hour -= 1;
gapMinute = 60 - myMinute + minute;
}
var gapHour = hour - myHour;
if(gapHour < 0)
{
day -= 1;
gapHour = 24 - myHour + hour;
}
var gapDay = day - myDay;
if(gapDay < 0)
{
month -= 1;
gapDay = getDaysOfMonth(birthday) - myDay + day;
}
var gapMonth = month - myMonth;
if(gapMonth < 0)
{
year -= 1;
gapMonth = 12 - myMonth + month;
}
var gapYear = year - myYear;
if(gapYear < 0)
{
gapYear = 0;
}
var dateStr = gapYear+"岁 " +
(gapMonth<10? ("0"+gapMonth): gapMonth)+"月 " +
(gapDay<10? ("0"+gapDay): gapDay)+"天 " +
(gapHour<10? ("0"+gapHour): gapHour)+"时 " +
(gapMinute<10? ("0"+gapMinute): gapMinute)+"分 " +
(gapSecond<10? ("0"+gapSecond): gapSecond)+"秒";
return dateStr;
}还有两个计算所须的方法：
//获取当月的天数
function getDaysOfMonth(dateStr)
{
var date = new Date(dateStr);
var year = date.getFullYear();
var mouth = date.getMonth() + 1;
var day = 0;
if(mouth == 2)
{
day= isLeapYear(year) ? 29 : 28;
} else if(mouth == 1 || mouth == 3 || mouth == 5 ||
mouth == 7 || mouth == 8 || mouth == 10 || mouth == 12)
{
day= 31;
} else
{
day= 30;
}
return day;
}
//判断是否为闰年
function isLeapYear(year)
{
return (year%4==0 && year%100!=0)||(year%400==0);
}提示：你可以先修改部分代码再运行。
