I have 2 textboxes , txtDOB and txtAge

I am using jquery datepicker to get the date in txtDOB (date of birth textbox)

What i want is when i select date of birth from datepicker in my date of birth textbox i.e txtDOB

I want the age to be calculated automatically On age textbox i.e txtAge

I searched on internet but i am not finding the perfect one. I am stuck so far i have not done any coding to calculate age based on DOB.

Any help or any suggestion will be much appreciated

Thanks

hi Ashwani,
you need to access date from textbox and show year in another textbox.
let say txtDOB and where you show Age is txtAge ,use following javacsript on txtDOB textChange event.
function calculateAge() {
var d1 = $('.txtDOB').datepicker('getDate');
var d2 = new Date();
var oneDay = 364*24*60*60*1000;
var diff = 0;
if (d1 && d2) {

diff = Math.round(Math.abs((d2.getTime() - d1.getTime())/(oneDay)));
}
$('.calculated').val(diff);
$('.txtAge').val(d1)
}
