您可以使用 enabledDates 选项启用单个日期而不是daysOfWeekDisabled.

您可以创建一个辅助函数，该函数使用momentjs返回具有给定月份的第一个和第三个星期三的数组.可以在此处找到一个示例.

You can create an helper function that returns an array with the first and the third Wednesday of a given month using momentjs. An example can be found here.

您可以为 dp.update 添加一个列表器来更新您的列表用户更改月份时的启用日期(使用 enabledDates 函数).

You can add a listner for dp.update to update your enabled dates (using enabledDates function) when the user changes month.

这里有一个完整的工作示例:

Here a complete working example:

function getFirstAndThirdWed(year, month){
    // Convert date to moment (month 0-11)
    var myMonth = moment({year: year, month: month});
    // Get first Wednesday of the first week of the month
    var firstWednesday = myMonth.weekday(2);
    // Check if first Wednesday is in the given month
    if( firstWednesday.month() != month ){
        firstWednesday.add(1, 'weeks');
    }
    // Get 3rd Wednesday of the month
    var third = firstWednesday.clone().add(2, 'weeks');
    return [firstWednesday, third];
}

$('.bootstrap-date-picker').datetimepicker({
  locale: 'fr',
  useCurrent: false,
  enabledDates: getFirstAndThirdWed(moment().year(), moment().month()),
  format: "ll",
  minDate: moment().startOf('day'),
}).on("dp.update", function (e) {
  if( e.viewDate ){
    var enabledDates = getFirstAndThirdWed(e.viewDate.year(), e.viewDate.month());
    $('.bootstrap-date-picker').data("DateTimePicker").enabledDates(enabledDates);
  }
});

在minDate选项中添加了 startOf('day') 以防止出现问题当前日期是每月的第一个星期三，而您尝试选择它.

Added startOf('day') in minDate option to prevent problem when the current date is the first Wednesday of the month and you try to select it.
