@jambriz哇，真是一個兩歲的問題 – shinjuo 2014-05-20 17:33:56

document.getElementById需要一個字符串。你給它一個未聲明價值：

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

應該

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

注意引號。其次，這一行：minuteOne + minuteTwo + minuteThree + minuteFour + minuteFive是串聯字符串，而不是添加。您需要在所有值上調用parseInt，以便它們添加，而不是連接字符串。

第三，這條線

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

應該

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

看起來像你有一個錯字引用您的變量。應用了所有修復程序後，JavaScript看起來像這樣：

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; 
}

而且它似乎工作。

一個討厭的評論說，沒有解決問題 – shinjuo 2011-06-13 18:00:50

@shinjuo編輯包含發現的其他錯誤。 – vcsjones 2011-06-13 18:01:31

我做了最後一分鐘的修改，添加'var extraHours = Math.floor（totalMinutes/60）; '使小時文本框不包含分鐘的小數部分。 – vcsjones 2011-06-13 18:10:47

document.getElementById(totalMinute).value = minuteLeft;

應該

document.getElementById(totalMinute).value = minutesLeft;

經常檢查您的變量名。

getElementById(minOne)

你在路過MINONE等作爲變量時，你實際上是試圖用它們作爲文字字符串。把它們放在引號代替，即..

的getElementById（「MINONE」）
