这是 AlwaysHelpings 答案的副本，但采用了不同的方法来禁用一个月的最后三天。

var dateToday = new Date(); 

$("#datepicker").datepicker({
  beforeShowDay: noLastThreeDays,
  minDate: dateToday
});

function noLastThreeDays(date){
   //REM: Last day of month
  var tLastDayOfMonth = new Date(date.getFullYear(), date.getMonth() + 1, 0);
  
  //REM: Date of the passed date
  var tDate = date.getDate();

  //REM: Lock the last three days of the month
  if(
    tDate === tLastDayOfMonth.getDate() ||
    tDate === tLastDayOfMonth.getDate()-1 ||
    tDate === tLastDayOfMonth.getDate()-2
  ){
    return [false, "closed", "Sorry We are closed"]
  }
  else{
   return [true, "", ""]
 }
}
