Question

我正在寻找一个计算两个工作日之间天差的函数。像，例如。

周一 - 周五 = 4
周日 - 周六 = 6

谢谢！

Answer 1

只需创建一个包含工作日值的对象。

暂且称它为weekdays。此对象的目的是保留一周中每一天的值。

然后创建一个算法以找出差异。

var weekdays = {
       "Monday" : 1,
       "Tuesday" : 2,
       "Wednesday" : 3,
       "Thursday" : 4,
       "Friday" : 5,
       "Saturday" : 6,
       "Sunday" : 7
}

getBetweenWeekDays = function(day1, day2){
   if(weekdays[day1] <= weekdays[day2])
     return weekdays[day2] - weekdays[day1];
   return 7 - weekdays[day1] + weekdays[day2];
};
console.log('Monday - Friday = ' + getBetweenWeekDays('Monday','Friday')); 
console.log('Sunday - Saturday = ' + getBetweenWeekDays('Sunday','Saturday'));
console.log('Wednesday - Tuesday = ' + getBetweenWeekDays('Wednesday','Tuesday'));
console.log('Tuesday - Wednesday = ' + getBetweenWeekDays('Tuesday','Wednesday'));
