请教一个年龄算法问题

Question

用DateDiff
myAge=DateDiff("yyyy","12/31/1976",Date)

Answer 1

对不起,我看错了,我提供的例子是用VBScript的.

Answer 2

用当前年减去出生年，OK？
var date=new Date();
var age=date.getFullYear()-1980;
alert(age);

Answer 3

<SCRIPT LANGUAGE="JavaScript">
<!--
function getAge(birth){//参数为出生年月,如1980/5/9
  var now=new Date();
  var old=new Date(birth);
  //alert(now)
  alert(" 此人年龄为"+(now.getFullYear()-old.getFullYear())+"岁");
  alert("天数为"+Math.round(Math.abs(old.getTime()-now.getTime())/(24*60*60*1000))+"天");
}
//-->
</SCRIPT>

Answer 4

<script language=javascript> 
<!-- 
var year1
var a=new Date("12/23/1983")
year1=a.getFullYear()var age,year2
var now_time=new Date()
year2=now_time.getFullYear()
age=year2-year1
document.write("年龄:"+age)
-->
</script>
