I want to calculate the age automatically after a date is selected, but it's not working in jquery-3.3.1, I hope you guys can help me
<script type="text/javascript">
$('#tgl_lahir').datepicker({
onSelect: function(value, ui) {
var today = new Date(),
age = today.getFullYear() - ui.selectedYear;
$('#umur').val(age);
},
maxDate: '+0d',
changeMonth: true,
changeYear: true,
defaultDate: '-18yr',
});
</script>
For me it works.
$('#tgl_lahir').datepicker({
onSelect: function(value, ui) {
var today = new Date(),
age = today.getFullYear() - ui.selectedYear;
$('#umur').val(age);
},
maxDate: '+0d',
changeMonth: true,
changeYear: true,
defaultDate: '-18yr',
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
