javascript date validation check

Question

I will get the date of birth value dynamically from users visiting to the site, but when the user will insert birthday value I have to check whether the user is 18 years old or not.

user will insert a value like 18/09/2012 as dd/mm/yyyy format.

    var arr   = date.split("/"); //date is the value of birth date.
    var day   = arr[0];
    var month = arr[1];
    var year  = arr[2];

How should I do it?

Wouldn't searching SO with `[javascript] age validation` provide some answers? — KooiInc, Sep 03 '12 at 13:16

Take a look at the following question, it will help you calculate the age -
Calculate age in JavaScript

function getAge(dateString) 
{
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) 
    {
        age--;
    }
    return age;
}
