Age Calculation

[ekendricks]

I have searched for a generic javascript age calculation function, with no avail. I need to return the age in years, by substracting two dates, allowing for +/- 1 depending on birth month.

Using: ASP - Javascript

Form Name: Dui
1st Date: DOB -- mm/dd/yyyy
2nd Date: DateWritten-- mm/dd/yyyy
Return to: Age - int

Can anyone please assist, or point me to a generic script that would serve my purpose.

Thanks

Hello.

This may be a really illogical way to approach this, but you could have the DOB as variable dob and then statement it as such:

HTML: Select all

<script type="text/javascript">
<!--
var dob = "mm/dd/1991";

if (dob == "mm/dd/1992")
{
document.write("Happy Birthday");
}
if (dob == "mm/dd/1990")
{
document.write("Happy Birthday");
}
if (dob == "mm/dd/1991")
{
document.write("Happy Birthday");
}
//-->
</script>

This is a really time-wasted way of doing it, but it could work. I don't know Javascript very well by the way

Thanks,

Thanks for the response.....Not exactly what I'm looking for. What I need is something on the order of the script below.

---------------------------------------------------------

<script language="JavaScript">
function age() {

var DOB = (document.Dui.DOB.value);
var DateWritten = (document.Dui.DateWritten.value);

If Month(DateWritten) < Month(DOB) Or (Month(DateWritten) = _
Month(DOB) And Day(DateWritten) < Day(DOB)) Then
document.Dui.Age.value = Year(DateWritten) - Year(DOB) - 1
Else
document.Dui.Age.value = Year(DateWritten) - Year(DOB)
End If
End Function
}
</script>
---------------------------------------------------------------

When I run the above script, I get no results: "Error on page".

Thanks

I dont know much about JavaScript but this page seems to do what you want

I'm sure if you looked through their source code you could piece together what you want and change it to do what you need.

Ive done some more digging and something like

age=yearCurrent-yearOfBirth;
if(monthOfBirth-monthCurrent<0)age--;
else if(monthOfBirth-monthCurrent==0)
if(dayOfBirth-dayCurrent<0)age--;
