He estado intentando durante horas hacer que mis cartas de juego giren cuando el jugador hace clic en ellas. Cuando se activa eventListener, debe ejecutar la función flip que alterna entre el anverso y el reverso de una tarjeta. ¿Qué estoy haciendo mal?
const playingCards = document.querySelectorAll('.playing-cards'); function flipCard(){; this.classList.toggle("flip") } playingCards.forEach((card) => card.addEventListener("click", flipCard)); .playing-cards{ display: inline-block; padding: 20px; position: relative; cursor: pointer; } .playing-cards .flip{ transform: rotateY(180deg); } .front-card{ background-color: aqua; width: 300px; height: 300px; transform: rotateX(0deg); } .back-card{ background-color: greenyellow; width: 300px; height: 300px; transform: rotateY(180deg); } .front-card, .back-card{ width: 100%; height: 100%; position: absolute; backface-visibility: hidden; } <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" href="index.css"> <title>Document</title> </head> <div class="memory-game"> <div class="playing-cards"> <div class="front-card">A</div> <div class="back-card"></div> </div> <div class="playing-cards"> <div class="front-card">B</div> <div class="back-card"></div> </div> <div class="playing-cards"> <div class="front-card">a</div> <div class="back-card"></div> </div> <div class="playing-cards"> <div class="front-card">b</div> <div class="back-card"></div> </div> </div> <body> <script src=index.js></script> </body> </html>Respuesta derivada de aquí
const playingCards = document.querySelectorAll('.playing-cards'); function flipCard() { this.classList.toggle("flip") } playingCards.forEach((card) => card.addEventListener("click", flipCard)); /* The flip card container - set the width and height to whatever you want. We have added the border property to demonstrate that the flip itself goes out of the box on hover (remove perspective if you don't want the 3D effect */ .memory-game { background-color: transparent; border: 1px solid #f1f1f1; perspective: 1000px; /* Remove this if you don't want the 3D effect */ } /* This container is needed to position the front and back side */ .playing-cards { display: inline-block; position: relative; width: 30px; height: 30px; text-align: center; transition: transform 0.8s; transform-style: preserve-3d; cursor: pointer;/*clickable-cursor*/ } /* Do an horizontal flip when you move the mouse over the flip box container */ .playing-cards.flip { transform: rotateY(180deg); } /* Position the front and back side */ .front-card, .back-card { position: absolute; width: 100%; height: 100%; -webkit-backface-visibility: hidden; /* Safari */ backface-visibility: hidden; } /* Style the front side (fallback if image is missing) */ .front-card { background-color: aqua; color: black; } /* Style the back side */ .back-card { background-color: greenyellow; color: white; transform: rotateY(180deg); } <div class="memory-game"> <div class="playing-cards"> <div class="front-card">A</div> <div class="back-card"></div> </div> <div class="playing-cards"> <div class="front-card">B</div> <div class="back-card"></div> </div> <div class="playing-cards"> <div class="front-card">a</div> <div class="back-card"></div> </div> <div class="playing-cards"> <div class="front-card">b</div> <div class="back-card"></div> </div> </div>Editar: efecto de cursor agregado
