jQuery Datepicker minDate 计算一天中的时间

Question

我在我的网站上使用 Jquery datepicker，以便客户选择所需的交货日期。目前我已将 minDate 设置为 4(周末或节假日除外)。我刚刚意识到我需要考虑一天中的时间，这样如果有人在下午 2 点之后下订单，那么这一天就不会算在 minDate 中(因为发货已经太晚了)。

我找到了一些关于它的帖子，其中一篇似乎特别适用:

How do I restrict dates on datepicker after a certain time

但是，我很难将其应用到我当前的脚本(如下)。如果有人能告诉我如何将其融入其中，那就太酷了。

非常感谢您的时间和帮助! 〜苏珊

Answer 1

我终于解决了这个问题，所以我发布了我自己问题的答案。希望它能帮助某人。下面是完整的代码，minDate 为 4 天，不包括美国国家法定节假日和周末，以及 minDate 调整以排除当天下午 2 点之后的情况。

    <script type="text/javascript">
    $(document).ready(function() {

    //holidays
    var natDays = [
      [1, 1, 'New Year'], //2014
      [1, 20, 'Martin Luther King'], //2014
      [2, 17, 'Washingtons Birthday'], //2014       
      [5, 26, 'Memorial Day'], //2014
      [7, 4, 'Independence Day'], //2014
      [9, 1, 'Labour Day'], //2014
      [10, 14, 'Columbus Day'], //2013
      [11, 11, 'Veterans Day'], //2013
      [11, 28, 'Thanks Giving Day'], //2013 
      [12, 25, 'Christmas'] //2013     
];

    var dateMin = new Date();
    dateMin.setDate(dateMin.getDate() + (dateMin.getHours() >= 14 ? 1 : 0));
    AddBusinessDays(dateMin, 4);

    function AddBusinessDays(curdate, weekDaysToAdd) {
        while (weekDaysToAdd > 0) {
            curdate.setDate(curdate.getDate() + 1);
            //check if current day is business day
            if (noWeekendsOrHolidays(curdate)[0]) {
                weekDaysToAdd--;
            }
        }
    }    

    function noWeekendsOrHolidays(date) {
        var noWeekend = $.datepicker.noWeekends(date);
        if (noWeekend[0]) {
            return nationalDays(date);
        } else {
            return noWeekend;
        }
    }
    function nationalDays(date) {
        for (i = 0; i < natDays.length; i++) {
            if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) {
                return [false, natDays[i][2] + '_day'];
            }
        }
        return [true, ''];
    }
      $('#datepicker').datepicker({ 
            inline: true,
            beforeShowDay: noWeekendsOrHolidays,           
            showOn: "both",            
            firstDay: 0,
            dateformat: "dd/mm/yy",
            changeFirstDay: false,
            showButtonPanel: true,       
            minDate: dateMin            
    });
  });
