problem with date using java script

[sandhya]

Hi all,

    I"ve a form in which i "ve to validate using age. i"ve a text box called 'DateOfBirth' which inputs date of birth using a pop up calender. Using that i"ve to calculate the age of the user on change.

    For this i'm using a java script function onChange event for the field 'DateOfBirth'. In that function i"ve taken the Date() to take present date. That function displays the date as ddd mmm dd yyyy HH:MM:ss format like Fri Jan 09 2009 14:55:21. Here i should get the date in dd mm yyyy format. How can I get it. And how can I calculate the age. Can anyone help me.

the Date() function returns a date object you can  use the object's methods to get the specific values

example

var today=Date();
//the day
var day=today.getDay();

//the month
var month=today.getMonth();

//the year
var year=today.getFullYear();

Thanks for your help. It works. And How can I calculate age? By manual coding or is there any particular solution(single line) to find the time difference. If so, Can you give me that code. Thank you once again.

function getAge(bDateStr)
{
    var today  = new Date();
    var tDay   = today.getDate();
    var tMonth = today.getMonth();
    var tYear  = today.getFullYear();

    var bDateAry = bDateStr.split('-');
    var bDay     = bDateAry[0];
    var bMonth   = bDateAry[1]-1;
    var bYear    = bDateAry[2];

    var age = (tYear - bYear);

    if (bMonth>tMonth || (bMonth==tMonth && bDay>tDay))
    {
        var age = tYear - bYear - 1;
    }

    return age;
}
