已更新以包含更多代码

我们的网页设计师中风了，我一直在努力在他缺席的情况下完成一些设计。看来他不太可能帮助我。

我一直在使用打字板，其中一个页面有常见问题解答并使用 JavaScript，因此如果您单击问题，答案就会显示。然后，如果您单击答案文本，它会再次消失。我更新了一些答案文本，它似乎以某种方式破坏了 javascript 链接。我一直在做教程并尝试学习如何修复它。现在它只显示问题和答案，点击显示功能已丢失。

我们的设计师使用了 onclick=toggle

我已在此处包含代码（为了简洁，将答案文本替换为答案 1），看看是否有人可以指出它是如何损坏的/我如何修复它。可悲的是我对此的经验为零。非常感谢你:)

不是支持你想要的，但这可能对你有用：

<html><head>
<script type="Text/JavaScript"> function displayanswer(){ 
document.getElementById('question').innerHTML = ' //Put answer here'}
</script>

</head><body>
  <h1>Press on the question for answer</h1>
<button onclick="displayanswer"><h2 id="question"> //put your question here </h2></button>
</body></html>

我不确定代码的另一部分是否会导致此问题。

我在这里将其分解为jsfiddle：Fiddle

.FAA {
    display:none;
}

我刚刚添加了样式以最初将其隐藏。您可以切换它，如果您可能遇到其他问题，请告诉我

要将其包含在您的页面上，您只需在标签之前添加此行即可

<head>
<!--May have other code here -->
<style>
.FAA { display:none; }
</style>
</head>

这可能是最简单的方法

使用纯 HTML 创建点击显示答案元素。

details {
  margin: 0.3em 0;
}

summary {
  list-style: none;
  font-weight: bold;
}
