通过身份证号得到出生日期和性别的js代码

复制代码 代码如下:

<script language="javascript">
function showBirthday(val)
{
var birthdayValue;
if(15==val.length)
{ //15位SFZ号码
birthdayValue = val.charAt(6)+val.charAt(7);
if(parseInt(birthdayValue)<10)
{
birthdayValue = '20'+birthdayValue;
}
else
{
birthdayValue = '19'+birthdayValue;
}
birthdayValue=birthdayValue+'-'+val.charAt(8)+val.charAt(9)+'-'+val.charAt(10)+val.charAt(11);
if(parseInt(val.charAt(14)/2)*2!=val.charAt(14))
document.all.sex.value='男';
else
document.all.sex.value='女';
document.all.birthday.value=birthdayValue;
}
if(18==val.length)
{ //18位SFZ号码
birthdayValue=val.charAt(6)+val.charAt(7)+val.charAt(8)+val.charAt(9)+'-'+val.charAt(10)+val.charAt(11)+'-'+val.charAt(12)+val.charAt(13);
if(parseInt(val.charAt(16)/2)*2!=val.charAt(16))
document.all.sex.value='男';
else
document.all.sex.value='女';
if(val.charAt(17)!=IDCard(val))
{
document.all.idCard.style.backgroundColor='#ffc8c8';
}
else
{
document.all.idCard.style.backgroundColor='white';
}
document.all.birthday.value=birthdayValue;
}
}
