jQuery UI日期选择器：在接下来的3个工作日内关闭

Question

我正在使用以下代码来阻止我的jQuery UI日期选择器中的所有星期日。我今天也想阻止今天和今后3个工作日。有谁知道如何做到这一点？

$("#pick-delivery-date").datepicker({
    dateFormat: 'yy-mm-dd',
    altField: "#selected-delivery-date",
    altFormat: "DD, d MM, yy",
    beforeShowDay: function(date){
        var day = date.getDay();
        return [(day != 0), ''];
    }
}); 

Answer 1

如何使用minDate选项，比如......

{minDate：+3}

Answer 2

var unavailableDates = ["9-5-2011","14-5-2011","15-5-2011"];

$("#pick-delivery-date").datepicker({
    dateFormat: 'yy-mm-dd',
    altField: "#selected-delivery-date",
    altFormat: "DD, d MM, yy",
    beforeShowDay: function(date){
        dmy = date.getDate() + "-" + (date.getMonth()+1) + "-" + date.getFullYear();
      if ($.inArray(dmy, unavailableDates) < 0) {
        return [true,"","Book Now"];
      } else {
        return [false,"","Booked Out"];
      }
    }
});
