Datepicker onSelect not working

问题

I have the function below that doesn't seem to work and could do with a little help please. The function basically adds 30 days to the date selected with the datepicker.

$('#datepicker').datepicker({
   onSelect: function(dateText, inst) { 

       var date = new Date(dateText);
       date.setDate(date.getDate() + 30);
       date.format('mm/dd/yy');

       alert(date)
   }
});

I cant see where I am going wrong. When a date is selected it is adding a empty anchor to the address bar URL, if is helps.

Thanks.

The problem is that date.format('mm/dd/yyy') is blowing up.
