Change date Format in jQuery DatePicker to English dd/mm/yy?

MickySmig

I’m trying to format the date of a jQuery DatePicker to the English format ‘dd-mm-yy’, but I’m unable to get it to work. I’ve looked at all of the answers on this site and they all are using the same code as I am. Any idea why mine is not working? I have tried the two following ways:

$(function () {
    $(".datefield").datepicker({dateFormat:'dd/mm/yy'});
});

$(function () {
    $(".datefield").datepicker({ dateFormat: 'dd-mm-yy' });
});

Neither of these have worked. I was wondering if I had to include some other jQuery file to get the date to format to English.

Any help, as always, is greatly appreciated.
