答案 0 :(得分：1)
首先，您可以使用 event delegation [section 直接和委派事件]绑定单个事件处理程序，而不是每个按钮一个。
$(document).on("click", ".quiz__response", function(){
.is--unclickable
要仅针对与特定问题相关的答案添加$(".quiz__response").addClass("is--unclickable");，请进行更改
$(this).siblings().addBack().addClass("is--unclickable");
到
$(this).parent().children().addClass("is--unclickable");
或
fa-times
要显示fa-check或$(".fa-check").show();，请更改
$(".fa-times").show();
$(this).find("i").show();
至
$(this).siblings().addClass("is--false");（都在if和else语句中）
如果选中了正确的答案，请在 if语句中添加 $(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();
}
});
以红色显示剩余答案。
