Question

我正在尝试计算flex的年龄。我发现了上一个问题What is the best way to calculate Age using Flex?

我有点倾向于这个

private function calculateAge(dob:Date):String {        
var now:Date = new Date();

var ageDays:int = 0;
var ageYears:int = 0;
var ageRmdr:int = 0;

var diff:Number = now.getTime()-dob.getTime();
ageDays = diff / 86400000;
ageYears = Math.floor(ageDays / 365.24);
ageRmdr = Math.floor( (ageDays - (ageYears*365.24)) / 30.4375 );

if ( ageRmdr == 12 ) {
    ageRmdr = 11;
}

return ageYears + " years " + ageRmdr + " months"; }

但我不明白100％的事情正在发生。

如何将此实现到我的代码中，如果日期是12/23/1990？

另外，如果提供两个日期而不是使用当前日期，我将如何修改此代码以计算年龄？例如。 12/23/1990 - 10/15/1999

谢谢！

Answer 1

我想可以改变如下：

private function calculateAge(dob:Date, startfrom:Date):String {        

var ageDays:int = 0;
var ageYears:int = 0;
var ageRmdr:int = 0;

var diff:Number = startfrom.getTime()-dob.getTime();
ageDays = diff / 86400000;
ageYears = Math.floor(ageDays / 365.24);
ageRmdr = Math.floor( (ageDays - (ageYears*365.24)) / 30.4375 );

if ( ageRmdr == 12 ) {
    ageRmdr = 11;
}

return ageYears + " years " + ageRmdr + " months"; 
}

Answer 2

Date.getTime（）返回自1970年1月1日以来的毫秒数，因此diff是两个日期之间的毫秒数。代码除以86400000，因为这是每天的毫秒数。其余的应该是显而易见的。

要修改功能以允许输入两个日期，您可以更改此功能：


private function calculateAge(dob:Date, endDate:Date):String {        
   var ageDays:int = 0;
   var ageYears:int = 0;
   var ageRmdr:int = 0;
   var diff:Number = endDate.getTime() - dob.getTime();

   ageDays = diff / 86400000;
   ageYears = Math.floor(ageDays / 365.24);
   ageRmdr = Math.floor( (ageDays - (ageYears*365.24)) / 30.4375 );

   if ( ageRmdr == 12 ) {
      ageRmdr = 11;
   }

   return ageYears + " years " + ageRmdr + " months";
}
