2019獨角獸企業重金招聘Python工程師標準>>>

?要設置9~18點上下班，中午一小時午休，刨掉周六日，網上找了找沒找到合適的方法，自己寫了一個

<script type="text/javascript">function countSc(str1,str2){if(!str1 || !str2){return 0;}//開始構造兩個日期對象var datetime1 = new Date(), datetime2 = new Date();datetime1.setFullYear(str1.substr(0,4),str1.substr(5,2)-1,str1.substr(8,2));datetime2.setFullYear(str2.substr(0,4),str2.substr(5,2)-1,str2.substr(8,2));datetime1.setMilliseconds(0);datetime2.setMilliseconds(0);datetime1.setHours(str1.substr(11,2),0,0);datetime2.setHours(str2.substr(11,2),0,0);if(datetime1.getDay() == 0 || datetime1.getDay() == 6){datetime1.setDate(datetime1.getDate() - 1);datetime1.setHours(23,0,0);}if(datetime1.getDay() == 0 || datetime1.getDay() == 6){datetime1.setDate(datetime1.getDate() - 1);datetime1.setHours(23,0,0);}if(datetime2.getDay() == 0 || datetime2.getDay() == 6){datetime2.setDate(datetime2.getDate() + 1);datetime2.setHours(0,0,0);}if(datetime2.getDay() == 0 || datetime2.getDay() == 6){datetime2.setDate(datetime2.getDate() + 1);datetime2.setHours(0,0,0);}var travelHours = 0;var datetime3 = datetime1;for(var i = 0;i < 60; i++){var sd = datetime1.getDate(),ed = datetime2.getDate();if(sd == ed - 1){break;}datetime1.setDate(datetime1.getDate() + 1);if(datetime1.getDay() > 0 && datetime1.getDay() < 6){travelHours += 8;}}if (parseInt(datetime3.getHours()) <= 9) {travelHours += 8;}else {if (parseInt(datetime3.getHours())<= 12) {travelHours += 12 - parseInt(datetime3.getHours()) + 5;}else {if (parseInt(datetime3.getHours()) <= 18) {travelHours += 18 - parseInt(datetime3.getHours());}}}if (parseInt(datetime2.getHours()) >= 18) {travelHours += 8;}else {if (parseInt(datetime2.getHours()) >= 13){travelHours += 3 + parseInt(datetime2.getHours()) - 13;}else {if (parseInt(datetime2.getHours()) >= 9) {travelHours += parseInt(datetime2.getHours()) - 9;}}}return travelHours;} </script>
