javascript - 翻转所有卡片，但想一张一张地翻转

Question

我试图一张一张地翻转这些卡片，但它们一起翻转。

我相信我的 javaScript 中遗漏了一些东西。

在原始代码中，我在前面使用图像，在后面使用无序列表，我尝试在此处恢复它，只写“Front”和“Back”。

$(".flip").click(function() {
  $(".card").toggleClass("flipped");
});

.card-container {
  display: flex;
}
.card {
  width: 300px;
  height: 6rem;
  margin: 30px;
  transform-style: preserve-3d;
  transition: transform 1s;
}

.card figure {
  margin: 0;
  display: block;
  position: absolute;
  width: 100%;
  height: 100%;
  backface-visibility: hidden;
}

.card figure figcaption {
  padding: 0 1rem;
  backface-visibility: hidden;
  border: 1px solid gray;
}

.card button.flip {
  position: absolute;
  right: 1rem;
  margin: 0;
}

.card button.flip {
  top: 1rem;
}

.card .back {
  transform: rotateY( 180deg);
}

.card.flipped {
  transform: rotateY( 180deg);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card-container">
  <div class="card">
    <figure class="front">
      <figcaption>
        <h2>FRONT 1</h2>
        <button class="flip">+</button>
      </figcaption>
    </figure>
    <figure class="back">
      <figcaption>
        <h2>BACK 1</h2>
        <button class="flip">-</button>
      </figcaption>
    </figure>
  </div>

  <div class="card">
    <figure class="front">
      <figcaption>
        <h2>FRONT 2</h2>
        <button class="flip">+</button>
      </figcaption>
    </figure>
    <figure class="back">
      <figcaption>
        <h2>BACK 2</h2>
        <button class="flip">-</button>
      </figcaption>
    </figure>
  </div>
</div>

你们知道我做错了什么吗？

您可以使用 .closest() 方法仅翻转按钮所在的元素，而不是翻转类 .card 的所有元素 (它向上遍历 DOM 树，直到找到具有指定类的元素)。

$(this).closest(".card").toggleClass("flipped");

$(".flip").click(function() {
  $(this).closest(".card").toggleClass("flipped");
});

.card-container {
  display: flex;
}
.card {
  width: 300px;
  height: 6rem;
  margin: 30px;
  transform-style: preserve-3d;
  transition: transform 1s;
}

.card figure {
  margin: 0;
  display: block;
  position: absolute;
  width: 100%;
  height: 100%;
  backface-visibility: hidden;
}

.card figure figcaption {
  padding: 0 1rem;
  backface-visibility: hidden;
  border: 1px solid gray;
}

.card button.flip {
  position: absolute;
  right: 1rem;
  margin: 0;
}

.card button.flip {
  top: 1rem;
}

.card .back {
  transform: rotateY( 180deg);
}

.card.flipped {
  transform: rotateY( 180deg);
}
