文档。getElementById
接受一个字符串。您正在给它一个未声明的值：

var minuteOne = document.getElementById(minOne).value;
应该是

var minuteOne = document.getElementById("minOne").value;

document.getElementById('totalMinute').value = minutesLeft;
注意引号。第二，这行：
minuteOne+minuteTwo+minuteTree+minuteFour+minuteFove
是浓缩字符串，不做加法。您需要对所有值调用
parseInt
，以便它们进行加法，而不是concat字符串

第三，这条线

document.getElementById('totalMinute').value = minuteLeft;
应该是

var minuteOne = document.getElementById("minOne").value;

document.getElementById('totalMinute').value = minutesLeft;
看起来您的变量输入有误。应用所有修复后，JavaScript如下所示：

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;
}
它似乎可以工作。

document.getElementById（totalMinute）.value=minuteLeft

应该是

var minuteOne = document.getElementById("minOne").value;

document.getElementById('totalMinute').value = minutesLeft;

document.getElementById（totalMinutes）.value=minutesLeft


始终检查变量名。
document.getElementById（totalMinute）.value=minuteLeft


getElementById(minOne)


应该是


var minuteOne = document.getElementById("minOne").value;



document.getElementById('totalMinute').value = minutesLeft;



document.getElementById（totalMinutes）.value=minutesLeft

始终检查变量名


getElementById(minOne)


当您实际尝试将minOne等作为文本字符串使用时，您正在将其作为变量传入。将它们改为引号，即

getElementById（“minOne”）

当您实际尝试将minOne等作为文本字符串使用时，您正在将其作为变量传入。将它们改为引号，即

getElementById（“minOne”）


@shinjuo进行了编辑，以包含发现的其他bug。我在最后一分钟进行了更改，添加了
var extraHours=Math.floor（totalMinutes/60）使“小时”文本框不包含分钟的小数部分。@shinjuo进行了编辑，以包含发现的其他错误。我在最后一分钟进行了更改，添加了
