时间跨度任意指定 ` function generateTimes(step) { let size = Math.floor(24 * 60 / step); let timeArrays = new Array(size).fill('').map((item, index) => { let startVal = index * step; let endVal = (index + 1) * step; let startHour = Math.floor((startVal / 60)); let startMinute = (startVal % 60); let endHour = Math.floor((endVal / 60)); let endMinute = (endVal % 60); let startTime = ((startHour < 10) ? ('0' + startHour) : startHour) + ':' + (startMinute === 0 ? '00' : startMinute); let endTime = ((endHour < 10) ? ('0' + endHour) : endHour) + ':' + (endMinute === 0 ? '00' : endMinute);
return startTime + ' - ' + endTime;
});
return timeArrays;
}`
实现 console.log(generateTimes(30,"777")); 结果 (48) ["00:00 - 00:30", "00:30 - 01:00", "01:00 - 01:30", "01:30 - 02:00", "02:00 - 02:30", "02:30 - 03:00", "03:00 - 03:30", "03:30 - 04:00", "04:00 - 04:30", "04:30 - 05:00", "05:00 - 05:30", "05:30 - 06:00", "06:00 - 06:30", "06:30 - 07:00", "07:00 - 07:30", "07:30 - 08:00", "08:00 - 08:30", "08:30 - 09:00", "09:00 - 09:30", "09:30 - 10:00", "10:00 - 10:30", "10:30 - 11:00", "11:00 - 11:30", "11:30 - 12:00", "12:00 - 12:30", "12:30 - 13:00", "13:00 - 13:30", "13:30 - 14:00", "14:00 - 14:30", "14:30 - 15:00", "15:00 - 15:30", "15:30 - 16:00", "16:00 - 16:30", "16:30 - 17:00", "17:00 - 17:30", "17:30 - 18:00", "18:00 - 18:30", "18:30 - 19:00", "19:00 - 19:30", "19:30 - 20:00", "20:00 - 20:30", "20:30 - 21:00", "21:00 - 21:30", "21:30 - 22:00", "22:00 - 22:30", "22:30 - 23:00", "23:00 - 23:30", "23:30 - 24:00"] "777"
