Answer 1

$(function() {
    $( "#datepicker" ).datepicker({
     format: 'dd-mm-yyyy'
    });
  });

Answer 2

Here we go:

Try to reconstruct DateTime string as like this:

var dateObj = $("#datepicker").val();
var newDate = new Date(dateObj );
var formattedString = [newDate.Date(),newDate.Month()+1, newDate.getFullYear()].join("-");
alert(formattedString );

Answer 3

Pass "dd-mm-yy" as dateFormat.

$( "#datepicker" ).datepicker({ dateFormat: "dd-mm-yy" })
