两天后截止时间

Question

在 Datepicker 中，我试图将可选日期限制为星期日，并且仅在星期四 15:00 之前选择。我做错了什么？，仅限星期日有效，截止时间 15:00 有效，但前一天不是两天前。

$( "#deliverysunday" ).datepicker({
        dateFormat: "yy-mm-dd",
        showWeek: true,
        firstDay: 1,
        beforeShowDay: function(date){ return [date.getDay() == 0,""]},
        minDate: new Date().getHours() >= 15 ? 2 : 0
    });

Answer 1

如果我对您的问题的理解正确，您希望确保选择的最早日期是不晚于星期四 15:00 的第一个星期日。

minDate选项将控制哪个日期是最早的可选日期；确定截止时间的逻辑应该在您的 beforeShowDay 选项中：

$( "#deliverysunday" ).datepicker({
  dateFormat: "yy-mm-dd",
  showWeek: true,
  firstDay: 1,
  beforeShowDay: function(date) {
    return [isDateSelectable(date)];
  },
  minDate: 2
});


/**
 * Given a date, returns a boolean to indicate
 * whether the date should be selectable in a picker.
 * Tests the date according to the rules:
 *
 * - Is the date a Sunday?
 * - Is it currently before the cutoff time?
 */
function isDateSelectable(date) {
  // Cutoff interval = Sun@00:00 - Thu@15:00 = 57 hours
  var intervalInMillis = 57 * 60 * 60 * 1000;
  var now = new Date();
  var isPriorToInterval = now.getTime() < date.getTime() - intervalInMillis;

  // Is date a Sunday?
  var isSunday = date.getDay() === 0;

  return isSunday && isPriorToInterval;
}
