Solution 1:

ADyson has recognized it correctly. The program logic needs to be changed. In the selectAllow you were checking the array with startStr, so basically it will be checking with start date of selection only, not the whole selection. So, if you tried to select 14 oct to 18 oct, you needed to check / compare the disallowed dates with in this range. So, it is needed to loop through the disallowedDays array to check each date within the tried selection, like the following loop:

for(var i=0;i<disallowedDays.length;i++)   {
    var dd = newDate(disallowedDays[i]);
    if(dd.getTime() >= startDate.getTime() && dd.getTime() <= endDate.getTime()){
        returntrue;
    }
  }
