复制代码 代码如下:
<script language=javascript>
function ages(str)
{
var r = str.match(/^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2})$/);
if(r==null)return false;
var d= new Date(r[1], r[3]-1, r[4]);
if (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4])
{
var Y = new Date().getFullYear();
return("年龄 = "+ (Y-r[1]) +" 周岁");
}
return("输入的日期格式错误!");
}
alert(ages("1980-03-22"));
alert(ages("2002-01-31"));
alert(ages("2002-01-41"));
