How to change date format (MM/DD/YY) to (YYYY-MM-DD) in date picker

I have following datepicker script:

<script>
 $(function(){
        $("#to").datepicker();
        $("#from").datepicker().bind("change",function(){
            var minValue = $(this).val();
            minValue = $.datepicker.parseDate("mm/dd/yy", minValue);
            minValue.setDate(minValue.getDate()+1);
            $("#to").datepicker( "option", "minDate", minValue );
        })
    });
</script> 

Now dateformat is MM/DD/YY .how to change the date format to YYYY-MM-DD?

Answer

Use the dateFormat option

 $(function(){
        $("#to").datepicker({ dateFormat: 'yy-mm-dd' });
        $("#from").datepicker({ dateFormat: 'yy-mm-dd' }).bind("change",function(){
            var minValue = $(this).val();
            minValue = $.datepicker.parseDate("yy-mm-dd", minValue);
            minValue.setDate(minValue.getDate()+1);
            $("#to").datepicker( "option", "minDate", minValue );
        })
    });
