jQuery 控制具有相同类的单个 DIV（兄弟姐妹？）

Question

我正在为我的网站构建一个常见问题解答模块，我希望能够控制页面上的单个元素，即使它们都具有相同的类。 我相信这属于我还不熟悉的兄弟姐妹。

基本上，我希望用户能够单击问题 div，然后当他们单击它时，问题 div 设置为显示的同一 div 中的答案 div（如果这有意义！）。 任何帮助将不胜感激。

<div class="set">
  <div class="question">What is the airspeed velocity of an unladen swallow?</div>
  <div class="answer">Although a definitive answer would of course require further measurements, published species-wide averages of wing length and body mass, initial Strouhal estimates based on those averages and cross-species comparisons, the Lund wind tunnel study of birds flying at a range of speeds, and revised Strouhal numbers based on that study all lead me to estimate that the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles an hour. </div>
</div>

Answer 1

如果我正确理解你的问题，你应该
首先将所有答案设置为隐藏在 CSS 中：
.answer {display:none;}

然后您可以使用 jquery 显示单击问题的正确答案：

$(document).ready ( function () {
    $('.question').click(function() {
        $(this).next('.answer').show();
    });
});

编辑：您还可以使用 .toggle() 而不是 .show() 来显示/隐藏。

Answer 2

您可能应该查看这个问题，其中完成了类似的操作。

基本上，您首先需要为元素设置 ID，以便可以识别集合类中的单个元素。

然后，您可以添加一个单击事件处理程序，该处理程序将设置所选项目并显示适当的答案。
