我知道这是一篇旧帖子,但我刚刚遇到了同样的问题,由于链接断了,我发布了我的解决方案。

    $('#datepicker').datepicker({ 
    dateFormat: 'yy-mm-dd',
    defaultDate: '2011-05-10',
    changeMonth: true,
    changeYear: true,
    beforeShowDay: function(date){
        var selectedDate = new Date('2011-05-10');
        if (date.getFullYear() == selectedDate.getFullYear()
            && date.getMonthName() == selectedDate.getMonthName() 
            && date.getDate() >= selectedDate.getDate() 
            && date.getDate() <= selectedDate.addDays(6).getDate()
            ) {
            return [true, 'ui-datepicker-days-cell highlight', ""];
         }
        return [true, 'ui-datepicker-days-cell',""]
       }
    });
