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

That's what worked for me while all the rest gave NaN:

That only works if the dob format is mm/dd/yy

function getAge(dob) { return ~~((new Date()-new Date(dob))/(31556952000)) }
$("#dob").val()
$(dob).change(function(){
  $('.age').val(getAge($(this).val()));
});
