Question

我正在尝试一些东西，但我无法弄清楚问题。我有日历。如果我选择连月份，只有偶数日期应该是可选择的，如果我选择奇数月份，只有奇数日期应该是可选择的。但我的问题，当我选择奇数月它显示所有日期，当我选择甚至月份它没有显示任何日期。 http://jsfiddle.net/66688hft/1/

大卫是对的，你没有正确地度过这一天。试试这个：

$(function() {
  $( "#datepicker" ).datepicker({
      changeMonth: true,
      changeYear: true,
      showOn: "button",
      buttonImage: "calendar.gif",
      buttonImageOnly: true,
      buttonText: "Select date",
      beforeShowDay: function(date) {
          var day = date.getDate(),
              month = date.getMonth()+1;
          return [day % 2 == month % 2, ''];
      }
  });
}

Jquery BeforeShowDay选择偶数或奇数
