Date of birth validation for under 14

[borgkling2003]

Hi..

I am creating a form and I need a script to validate the date of birth entered to check whether they are under 14.

Does anyone know how to do it?

ask for their birthdate, then compare it like this:

var msIn14Years = 1000 * 60 * 60 * 365 * 14;

var dAge = new Date('06/24/1980');
var dToday = new Date();

if (dToday - dAge >= msIn14Years ) {
    alert('you are at least 14');
} else {
    alert('you are NOT at least 14');
}

i haven't tested this code.

You really need to do this comparison server-side... Doing it client-side will get any [under 14] script kiddie the ability to bypass it fairly easily.

Mind you, I guess they could just lie about their age anyway, so might not be such a big deal.

Hope this helps,
