  • 我已经更新了索引。html和脚本。js

如果我点击了错误的答案…

  • 它没有给类按钮只是点击
  • 它给出了is-false类来纠正答案和quiz__info

如果我点击右键回答…

  • 它不会给出错误答案的is false类

    $(this).siblings().addBack().addClass("is--unclickable");
    $(this).siblings().show("quiz__info");  // Show extra info

首先，您可以使用事件委派[直接和委派事件部分]来绑定单个事件处理程序，而不是为每个按钮绑定一个事件处理程序。

$（.quiz__response）. on（单击，函数（）{
$（文档）. on（单击，.quiz__response，函数（）{

仅添加。is--不可点击在与特定问题相关的答案上，更改$（“.quick\uu response”）。addClass（“is--不可链接”）
到
$（此）。兄弟姐妹（）。addBack（）。addClass（“is--不可链接”）
或
$（此）。父项（）。儿童（）。addClass（“is--不可链接”）

要显示fa时间或fa检查，请更改
$（“.fa检查”）。show（）
$（“.fa次”）。show（）
到$（此）。查找（“我”）。show（）（在if和else语句中）

并在if语句中添加$（this）. siblings（）. addClass（is--false）；，如果选中正确的答案，则将其余答案涂成红色。

完整js更改

  $(document).on("click", ".quiz__response", function() {
    $(this).siblings("button").addBack().addClass("is--unclickable");
    $(this).siblings(".quiz__info").show(); // Show extra info
    console.log("Clicked");

    if ($(this).hasClass("answer--true")) {
      $(this).addClass("is--true");
      $(this).siblings("button").addBack().find("i").show();
      $(this).siblings("button").addClass("is--false");

      // Update score
      score++
      $(".quiz__correct").html(score);
      $(".quiz__correct--mobile").html(score);
    } else {
      $(this).addClass("is--false");
      $(this).find("i").show();
    }
  });
