JS计算工作日

function stringToDate(dateString){ 
    dateString = dateString.split('-'); 
    return new Date(dateString[0], dateString[1] - 1, dateString[2]); 
}

function countWorkDay(date1, date2){
        date1 = stringToDate(date1);
        date2 = stringToDate(date2);
        delta = (date2 - date1) / (1000 * 60 * 60 * 24) + 1; // 计算出总时间

        weeks = 0;
        for(i = 0; i < delta; i++){
            if(date1.getDay() == 0 || date1.getDay() == 6) weeks ++;  // 若为周六或周天则加1
            date1 = date1.valueOf();
            date1 += 1000 * 60 * 60 * 24;
            date1 = new Date(date1);
        }
        return delta - weeks;
    }
    console.log(countWorkDay('2017-08-01','2017-08-06'));  // 4
