除了讓用戶的答案不區分大小寫，關於如何在用戶有正確答案時放置綠色勾號標記的任何想法？目前，如果用戶是正確的，它是空白的。所以我需要一些顯示正確答案的綠色勾號和錯誤答案的紅色十字。如何讓用戶回答不區分大小寫的問題？

我的Javascript，你可以將任何字符串

"string".toLowerCase()

或者在一個變量的情況下，爲小寫：

variable.toLowerCase()

這種方法使得它更容易做比較，因爲這些字母將成爲全部小寫。我希望這就是你所問的。綠色勾號標記，因爲您也想知道如何解決從文檔對象模型中添加/刪除內容的問題。一種方法是顯示圖像，然後根據答案將圖像來源更改爲檢查或「x」標記。例如：

if(true) { //if the answer is correct 
    document.getElementById('image').src = 'check.png'; 
} else { 
    document.getElementById('image').src = 'wrong.png'; 
}

如何將此代碼合併到我的代碼中？ – Jason 2014-12-03 23:02:20

要合併Gwiddle的答案，無論你希望它是你需要有一個形象的每個答案旁邊，它。然而，你應該開始給它沒有源，並給它「markbox0」或類似的ID

<img src="" id="markbox0" alt="mark">

現在，您將能夠更改代碼的圖像拉斯特的源如圖Gwiddle使用

document.getElementById('markbox').src = 'check.png';

此外，作爲一般的編碼提示，如果你的項目的長列表進行一組類似的代碼，它往往是更容易使用一個循環，而不是寫出來的每一個。如果你想在你的頁面添加更多的問題，這將特別有用。一個簡單的'for'循環將節省大量的空間和寫作。在這裏，你使用一個變量來計算每次循環代碼的運行時間，讓你能夠瀏覽一長串的東西。例如，你的回答校驗碼可以用以下方式實現：

for (var i = 0; i <= Answers.length; i = i + 1){ 
    if (Answers[i] == UserAnswers[i]) 
     {count0 = count0 + 1; 
     document.getElementById('markbox' + String(i)).src = 'check.png';} 
    else 
     {count0 = count0; 
     document.getElementById('markbox' + String(i)).src = 'cross.png';} 
}

這個循環與運行中有你的答案列表中的項目「我」爲號，次數的代碼。我的值從0開始，每次循環運行時增加1。第一次，它會將Answers [0]與UserAnswers [0]進行比較，並確定圖像的來源，其中id爲'markbox0'，然後再次用1，依此類推。

希望能幫到你。
