document.getElementById接受一个字符串。 你给它一个未声明的值：
var minuteOne = document.getElementById(minOne).value;
应该
var minuteOne = document.getElementById("minOne").value;
注意引号。 其次，这一行： minuteOne + minuteTwo + minuteThree + minuteFour + minuteFive是连接字符串，而不是做加法。 您需要对所有值调用parseInt以便它们进行添加，而不是连接字符串。
三、这条线
document.getElementById('totalMinute').value = minuteLeft;
应该
document.getElementById('totalMinute').value = minutesLeft;
看起来你有一个错字引用你的变量。 应用所有修复后，JavaScript 看起来像这样：
function getTimes(){
var minuteOne = parseInt(document.getElementById('minOne').value);
var minuteTwo = parseInt(document.getElementById('minTwo').value);
var minuteThree = parseInt(document.getElementById('minThree').value);
var minuteFour = parseInt(document.getElementById('minFour').value);
var minuteFive = parseInt(document.getElementById('minFive').value);
var hourOne = parseInt(document.getElementById('hourOne').value);
var hourTwo = parseInt(document.getElementById('hourTwo').value);
var hourThree = parseInt(document.getElementById('hourThree').value);
var hourFour = parseInt(document.getElementById('hourFour').value);
var hourFive = parseInt(document.getElementById('hourFive').value);
var totalMinutes = minuteOne + minuteTwo + minuteThree + minuteFour + minuteFive;
var extraHours = Math.floor(totalMinutes / 60);
var minutesLeft = totalMinutes % 60;
var totalHours = hourOne + hourTwo + hourThree + hourFour + hourFive + extraHours;
document.getElementById('totalMinute').value = minutesLeft;
document.getElementById('totalHour').value = totalHours;
}
它似乎有效。

document.getElementById(totalMinute).value = minuteLeft;
应该
document.getElementById(totalMinute).value = minutesLeft;
始终检查您的变量名称。

getElementById(minOne)
当您实际尝试将它们用作文字字符串时，您将 minOne 等作为变量传递。 将它们放在引号中，即..
getElementById("minOne")
