DIV on DIV打開按鈕單擊

Question

我為此游戲制作了3種不同的困難。 我現在擁有的代碼僅允許我單擊“中”和“難”。 這只會更改DIV中的元素。 我似乎無法使“簡單”按鈕正常工作，甚至使其他按鈕無法正常工作。 現在，它不會用另一個DIV替換整個DIV，而只是在當前一個DIV中顯示另一個DIV的內容。 我認為這可能是由於“ .innerHTML”部分引起的，我不確定將其切換為何種功能才能正常工作。

<script>
  function show(param_div_id) {
    document.getElementById('divbox3').innerHTML = document.getElementById(param_div_id).innerHTML;
  }

</script>

<!-- Border for the game --> 
   <form id = "divbox3" name = "quiz" > 
      <div class="game-button" style="width:50%"> 
         <button onclick="show('divbox3')">Easy</button>
         <button onclick="show('divbox3med')">Medium</button>
         <button onclick="show('divbox3hard')">Hard</button>
      </div>
      <br>
      <br>

謝謝

Answer 1

我看了看jsFiddle並進行了更正。

在這里看看： https : //jsfiddle.net/e7862c3d/

function show(param_div_id) {  
   var quizList = document.getElementsByClassName('quiz');

   for(var i=0; i < quizList.length; i++) {
       quizList[i].style.display = 'none';
   }
   document.getElementById(param_div_id).style.display = 'block';

}

您在表單內重復按鈕，我認為最好在實例中顯示/隱藏表單。

Answer 2

啟動程序時，它以簡單的測驗開始。 當您按下“中等”，它從交換的代碼divbox3 （容易）的形式從代碼divbox3medium （介質）的形式。 這會將您看到的形式從簡單的水平測驗更改為中等水平的測驗。 當您按下“簡單”按鈕時，它divbox3中的代碼（現在包含中級測驗的代碼，而不再包含簡單測驗的代碼）與divbox3的代碼（假設您是簡單代碼） divbox3 ，但事實並非如此。

就像這樣。

X = Easy
Y = Medium
Z = Hard

按下中鍵

X = Y = Medium
Y = Medium
Z = Hard

按下簡易按鈕

X = X = Medium
Y = Medium
Z = Hard

要解決此問題，可以通過制作divbox3 ， divbox3easy ， divbox3medium和divbox3hard來做到這divbox3hard 。 然后，您divbox3使用所需的任何級別測驗的內容來更改divbox3的內容，但不會覆蓋簡單測驗的代碼。

若要更簡便地解決此問題，您需要向可見表單（而不是display: none表單）添加一個visible類，然后更改show函數以執行以下操作：

function show(param_div_id) {
    // Loop through all elements with the visible class and both remove the class and set the display to none
    // Add the visible class to param_div_id and set it's display to block
}
