JQuery Age calculation on date

Question

Am I missing something in the following jQuery code?

var dob = $(\'#date\').val();
if(dob != \'\'){
    var today = new Date();
    var dayDiff = Math.ceil(t         


        

Answer 1

 jQuery("#dob").on('change',function(){
       var dob1 = jQuery(this).val();
       var dob = $.datepicker.formatDate('yy-mm-dd', new Date(dob1));
       var str = dob.split('-');    
       var firstdate=new Date(str[0],str[1],str[2]);
       var today = new Date();        
       var dayDiff = Math.ceil(today.getTime() - firstdate.getTime()) / (1000 * 60 * 60 * 24 * 365);
       var age = parseInt(dayDiff);
       jQuery("#age").html(age+' years old');
   });
