【问题标题】：Toggle flip cards切换翻转卡片
【发布时间】：2022-01-03 05:18:47
【问题描述】：

我有一个简单的投资组合网站，其中包含三张翻转卡。到目前为止，翻转功能就在那里，我基本上已经完成了网站。问题是，我希望其他卡在单击一张卡时切换。换句话说，我希望一次只能翻转一张牌。我怎样才能做到这一点？

标签： javascript html css flip card

【解决方案1】：

一种方法是：当一张卡片被点击时，“取消翻转”所有其他卡片，然后切换被点击卡片的翻转状态。

function flipCard() {

    // "unflip" all cards other than the one clicked
    cards.forEach((card) => {
      if(card != this) {
        card.classList.remove('is-flipped');
      }
    });
    
    this.classList.toggle('is-flipped');
};

演示sn-p：

const cards = document.querySelectorAll(".card__inner");

function flipCard() {

    // "unflip" all cards other than the one clicked
    cards.forEach((card) => {
      if(card != this) {
        card.classList.remove('is-flipped');
      }
    });
    
    this.classList.toggle('is-flipped');
};

cards.forEach((card) =>card.addEventListener("click", flipCard));

:root {
    --dark: #312b2b;
    --light: #F5EFEB;
}

* {
    margin: 0;
    padding: 0;
}

body {
    background-color: var(--light);
    font-family: 'Poppins', sans-serif;
    width: 100%;
    min-height: 100vh;

    flex-direction: row;
}

.card {
    width: calc(100% / 3);
    height: 100vh;

    height: 100%;
    transition: transform 1s;
    transform-style: preserve-3d;
    cursor: pointer;
    position: relative;
}

.card__inner.is-flipped {
    transform: rotateY(180deg);
}

.card__face {
    position: absolute;
    width: 100%;
    height: 100%;
    -webkit-backface-visibility: hidden;
    backface-visibility: hidden;
    overflow: hidden;
}

.card__face--front {

非常感谢！
@HaydenDyer 很高兴这有帮助！

【解决方案2】：

这很简单，如果卡片被翻转了，请解开它并翻转你想要的卡片

你的脚本应该是这样的

const cards = document.querySelectorAll(".card__inner");

function flipCard() {
    for(let i = 0; i < cards.length; i++) { 
        if(cards[i].classList.contains('is-flipped')) cards[i].classList.remove('is-flipped') 
    }
    this.classList.toggle('is-flipped');
};

cards.forEach((card) =>card.addEventListener("click", flipCard));
