你可以使用以下函数来计算： 函数1： function calculateHours(startTime, endTime, breakTime) { let totalHours = 0; let startTimeHour = startTime.getHours(); let endTimeHour = endTime.getHours(); let breakTimeHour = breakTime.getHours(); totalHours = endTimeHour - startTimeHour - breakTimeHour; return totalHours; } 函数2： function calculateHours(startTime, endTime, breakTime) { let totalHours = 0; let startTimeMinutes = startTime.getMinutes(); let endTimeMinutes = endTime.getMinutes(); let breakTimeMinutes = breakTime.getMinutes(); totalHours = (endTimeMinutes - startTimeMinutes - breakTimeMinutes) / 60; return totalHours; }
