how to get the selected year in datepicker?

问题

I am using datepicker for my input name birth_day. And I want to calculate the age from the current year and selected year.

current_yr - selected_yr

but I have no idea on how can I get the selected year from date picker.

this is my code look like.

<script>
    function dateYear(){
        var d = new Date();
                var year = d.getFullYear();
                return year;
    }
    $(function() {
        $( "#id_birth_date" ).datepicker({ dateFormat: 'yy-mm-dd' });

        //how can I get the selected year?
    });

</script>

<input type="text" name="birth_day" id="bd">
<input type="text" name="age" id="ag">

does anyone can give me an idea about my case?

Do you mean:

$(function() {
     $("#id_birth_date").datepicker({
           onSelect: function(dateText, inst) {
              var startDate = new Date(dateText);
              var selectedYear = startDate.getFullYear(); // selected year
           }
     });
});

It will be possible.. after selecting date from datepicker

You will get property of datepicker1.year which will help you get year

After retrieving date into string use Convert.Toint32(strDate1)-Convert.Toint32(strDate2) ;

..Try it...Otherwise post you code,...

You should be able to utilize the val() function.

The selected answer has a problem: the dateText may not be parsed because it depends on text which can be customised. Below is the enhanced accurate answer. Otherwise you will end up using an undefined date object:

$(function() {
     $("#id_birth_date").datepicker({
           onSelect: function(dateText, inst) {
              var startDate = new Date(inst.selectedYear, inst.selectedMonth, inst.selectedDay);
              var selectedYear = startDate.getFullYear(); // selected year
           }
     });
});
