Drupal 6 datepicker，阻止周末和某些假期

Question

我的一位朋友有一个Drupal 6网站，用户可以在此选择未来的交付日期。最近，有几位顾客选择了周末和假期作为交货日期，我的朋友希望阻止他们这样做。

这是我们目前用来阻止周末的代码。有人可以帮助修改它以阻止圣诞节和除夕吗？

非常感谢！

drupal_add_js("
Drupal.behaviors.date_popup = function (context) {
  for (var id in Drupal.settings.datePopup) {
    $('#'+ id).bind('focus', Drupal.settings.datePopup[id], function(e) {
      if (!$(this).hasClass('date-popup-init')) {
        var datePopup = e.data;

                        // CUSTOM
        datePopup.settings.beforeShowDay = function(date) { 
			var day = date.getDay(); 
			return [(day != 0 && day != 6), '']; 
			
		}
       
        // Explicitely filter the methods we accept.
        switch (datePopup.func) {
          case 'datepicker':
            $(this)
              .datepicker(datePopup.settings)
              .addClass('date-popup-init')
            $(this).click(function(){
              $(this).focus();
            });
            break;

          case 'timeEntry':
            $(this)
              .timeEntry(datePopup.settings)
              .addClass('date-popup-init')
            $(this).click(function(){
              $(this).focus();
            });
            break;
        }
      }
    });
  }
};
    ",'inline');

更新：

我最终做了以下工作，这符合我们的需求：

drupal_add_js("
Drupal.behaviors.date_popup = function (context) {
  for (var id in Drupal.settings.datePopup) {
    $('#'+ id).bind('focus', Drupal.settings.datePopup[id], function(e) {
      if (!$(this).hasClass('date-popup-init')) {
        var datePopup = e.data;

         // CUSTOM
		
		datePopup.settings.beforeShowDay = function(date) {
        var day = date.getDay(), Sunday = 0, Monday = 1, Tuesday = 2, Wednesday = 3, Thursday = 4, Friday = 5, Saturday = 6;
        var closedDates = [[12, 31, 2015], [12, 25, 2015]];
        var closedDays = [[Saturday], [Sunday]];
        for (var i = 0; i < closedDays.length; i++) {
            if (day == closedDays[i][0]) {
                return [false];
            }

        }

        for (i = 0; i < closedDates.length; i++) {
            if (date.getMonth() == closedDates[i][0] - 1 &&
            date.getDate() == closedDates[i][1] &&
            date.getFullYear() == closedDates[i][2]) {
                return [false];
            }
        }

        return [true];
    }
       
        // Explicitely filter the methods we accept.
        switch (datePopup.func) {
          case 'datepicker':
            $(this)
              .datepicker(datePopup.settings)
              .addClass('date-popup-init')
            $(this).click(function(){
              $(this).focus();
            });
            break;

          case 'timeEntry':
            $(this)
              .timeEntry(datePopup.settings)
              .addClass('date-popup-init')
            $(this).click(function(){
              $(this).focus();
            });
            break;
        }
      }
    });
  }
};
    ",'inline');
