作者:海拥✘
这篇文章主要介绍了如何利用HTML、CSS 和 JavaScript 制作纸牌记忆游戏,文中的示例代码讲解详细,感兴趣的小伙伴可以跟随小编一起动手尝试一下
这节实验我们将使用 HTML、CSS 和 JavaScript 制作纸牌记忆游戏。
让我们开始吧!
知识点
animation-duration 属性
backface-visibility 属性
visibility 属性
animation-timing-function 属性
HTML 用户界面
HTML 代码用于设计项目的基本结构,其中包含了一个 h1 标题,分数、星级和游戏时间面板,纸牌卡片列表以及获胜时的恭喜面板。

CSS 部分
现在我们使用一些 CSS 属性来设置记忆纸牌游戏的样式。
一些基本样式
html { box-sizing: border-box; } *, *::before, *::after { box-sizing: inherit; } html, body { width: 100%; height: 100%; margin: 0; padding: 0; font-weight:bolder; } body { background: #ffffff; font-size: 16px; } .container { display: flex; justify-content: center; align-items: center; flex-direction: column; } h1 { font-family: 'Gloria Hallelujah', cursive; }
纸牌的样式
.deck { width: 85%; background: #716F71; padding: 1rem; border-radius: 4px; box-shadow: 8px 9px 26px 0 rgba(46, 61, 73, 0.5); display: flex; flex-wrap: wrap; justify-content: space-around; align-items: center; margin: 0 0 3em; } .deck .card { height: 3.7rem; width: 3.7rem; margin: 0.2rem 0.2rem; background: #141214;; font-size: 0; color: #ffffff; border-radius: 5px; cursor: pointer; display: flex; justify-content: center; align-items: center; box-shadow: 5px 2px 20px 0 rgba(46, 61, 73, 0.5); } .deck .card.open { transform: rotateY(0); background: #02b3e4; cursor: default; animation-name: flipInY; -webkit-backface-visibility: visible; backface-visibility: visible; animation-duration: .75s; } .deck .card.show { font-size: 33px; } .deck .card.match { cursor: default; background: #E5F720; font-size: 33px; animation-name: rubberBand; -webkit-backface-visibility: visible; backface-visibility: visible; animation-duration: .75s; } .deck .card.unmatched { animation-name: pulse; -webkit-backface-visibility: visible; backface-visibility: visible; animation-duration: .75s; background: #e2043b; } .deck .card.disabled { pointer-events: none; opacity: 0.9; }
animation-duration
属性定义动画完成一个周期需要多少秒或毫秒。这里的.75s
表示 0.75 秒。backface-visibility
属性定义当元素背面向屏幕时是否可见。这里的visible
值使得背面是可见的。
分数面板的样式
.score-panel { text-align: left; margin-bottom: 10px; } .score-panel .stars { margin: 0; padding: 0; display: inline-block; margin: 0 5px 0 0; } .score-panel .stars li { list-style: none; display: inline-block; } .score-panel .restart { float: right; cursor: pointer; } .fa-star { color: #FFD700; } .timer { display: inline-block; margin: 0 1rem; }
祝贺面板的样式
.overlay { position: fixed; top: 0; bottom: 0; left: 0; right: 0; background: rgba(0, 0, 0, 0.7); transition: opacity 500ms; visibility: hidden; opacity: 0; } .overlay:target { visibility: visible; opacity: 1; } .popup { margin: 70px auto; padding: 20px; background: #ffffff; border-radius: 5px; width: 85%; position: relative; transition: all 5s ease-in-out; } .popup h2 { margin-top: 0; color: #333; font-family: Tahoma, Arial, sans-serif; } .popup .close { position: absolute; top: 20px; right: 30px; transition: all 200ms; font-size: 30px; font-weight: bold; text-decoration: none; color: #333; } .popup .close:hover { color: #E5F720; } .popup .content-1, .content-2 { max-height: 30%; overflow: auto; text-align: center; } .show { visibility: visible; opacity: 100; } #starRating li { display: inline-block; } #play-again { background-color: #141214; padding: 0.7rem 1rem; font-size: 1.1rem; display: block; margin: 0 auto; width: 50%; font-family: 'Gloria Hallelujah', cursive; color: #ffffff; border-radius: 5px; }
visibility
属性指定一个元素是否是可见的。
动画
/* 卡片打开时的动画 */ @keyframes flipInY { from { transform: perspective(400px) rotate3d(0, 1, 0, 90deg); animation-timing-function: ease-in; opacity: 0; } 40% { transform: perspective(400px) rotate3d(0, 1, 0, -20deg); animation-timing-function: ease-in; } 60% { transform: perspective(400px) rotate3d(0, 1, 0, 10deg); opacity: 1; } 80% { transform: perspective(400px) rotate3d(0, 1, 0, -5deg); } to { transform: perspective(400px); } }
animation-timing-function
指定动画将如何完成一个周期,这里的ease-in
是让动画以低速开始。
/* 卡片匹配时的动画 */ @keyframes rubberBand { from { transform: scale3d(1, 1, 1); } 30% { transform: scale3d(1.25, 0.75, 1); } 40% { transform: scale3d(0.75, 1.25, 1); } 50% { transform: scale3d(1.15, 0.85, 1); } 65% { transform: scale3d(.95, 1.05, 1); } 75% { transform: scale3d(1.05, .95, 1); } to { transform: scale3d(1, 1, 1); } }
/* 卡片不匹配时的动画 */ @keyframes pulse { from { transform: scale3d(1, 1, 1); } 50% { transform: scale3d(1.2, 1.2, 1.2); } to { transform: scale3d(1, 1, 1); } }
媒体查询
/* 适用于 320px 以下的样式*/ @media (max-width: 320px) { .deck { width: 85%; } .deck .card { height: 4.7rem; width: 4.7rem; } } /* 适用于 768px 以上的样式*/ @media (min-width: 768px) { .container { font-size: 22px; } .deck { width: 660px; height: 680px; } .deck .card { height: 125px; width: 125px; } .popup { width: 60%; } }
JavaScript 部分
接下来让我们添加 Javascript
首先声明一些我们需要用到的变量:
// 卡片数组包含所有卡片 let card = document.getElementsByClassName("card"); let cards = [...card]; // 游戏中所有卡片 const deck = document.getElementById("card-deck"); // 声明 moves 变量 let moves = 0; let counter = document.querySelector(".moves"); // 声明星形图标的变量 const stars = document.querySelectorAll(".fa-star"); // 声明 matchedCard 的变量 let matchedCard = document.getElementsByClassName("match"); // 星级列表 let starsList = document.querySelectorAll(".stars li"); // 模板中的关闭图标 let closeicon = document.querySelector(".close"); // 声明 modal let modal = document.getElementById("popup1") // 打开卡片的数组 var openedCards = [];
洗牌功能
function shuffle(array) { var currentIndex = array.length, temporaryValue, randomIndex; while (currentIndex !== 0) { randomIndex = Math.floor(Math.random() * currentIndex); currentIndex -= 1; temporaryValue = array[currentIndex]; array[currentIndex] = array[randomIndex]; array[randomIndex] = temporaryValue; } return array; };
开始新游戏的功能
// 页面刷新/加载时洗牌 document.body.onload = startGame(); // 开始新游戏的功能 function startGame(){ // 清空 openCards 数组 openedCards = []; // 洗牌 cards = shuffle(cards); // 从每张卡片中删除所有现有的类 for (var i = 0; i < cards.length; i++){ deck.innerHTML = ""; [].forEach.call(cards, function(item) { deck.appendChild(item); }); cards[i].classList.remove("show", "open", "match", "disabled"); } // 重置 moves moves = 0; counter.innerHTML = moves; // 重置 rating for (var i= 0; i < stars.length; i++){ stars[i].style.color = "#FFD700"; stars[i].style.visibility = "visible"; } // 重置 timer second = 0; minute = 0; hour = 0; var timer = document.querySelector(".timer"); timer.innerHTML = "0 分 0 秒"; clearInterval(interval); }
显示卡片的功能
var displayCard = function (){ this.classList.toggle("open"); this.classList.toggle("show"); this.classList.toggle("disabled"); };
将打开的卡片添加到 OpenedCards 列表并检查卡片是否匹配
function cardOpen() { openedCards.push(this); var len = openedCards.length; if(len === 2){ moveCounter(); if(openedCards[0].type === openedCards[1].type){ matched(); } else { unmatched(); } } };
当卡片匹配时的功能
function matched(){ openedCards[0].classList.add("match", "disabled"); openedCards[1].classList.add("match", "disabled"); openedCards[0].classList.remove("show", "open", "no-event"); openedCards[1].classList.remove("show", "open", "no-event"); openedCards = []; }
当卡片不匹配时的功能
function unmatched(){ openedCards[0].classList.add("unmatched"); openedCards[1].classList.add("unmatched"); disable(); setTimeout(function(){ openedCards[0].classList.remove("show", "open", "no-event","unmatched"); openedCards[1].classList.remove("show", "open", "no-event","unmatched"); enable(); openedCards = []; },1100); }
暂时禁用卡片的功能
function disable(){ Array.prototype.filter.call(cards, function(card){ card.classList.add('disabled'); }); }
启用卡片并禁用匹配的卡片的功能
function enable(){ Array.prototype.filter.call(cards, function(card){ card.classList.remove('disabled'); for(var i = 0; i < matchedCard.length; i++){ matchedCard[i].classList.add("disabled"); } }); }
计算玩家的动作的功能
function moveCounter(){ moves++; counter.innerHTML = moves; // 第一次点击时启动计时器 if(moves == 1){ second = 0; minute = 0; hour = 0; startTimer(); } // 根据移动次数设置星级 if (moves > 8 && moves < 12){ for( i= 0; i < 3; i++){ if(i > 1){ stars[i].style.visibility = "collapse"; } } } else if (moves > 13){ for( i= 0; i < 3; i++){ if(i > 0){ stars[i].style.visibility = "collapse"; } } } }
显示游戏的时间
//初始化变量 var second = 0, minute = 0; hour = 0; var timer = document.querySelector(".timer"); var interval; //计时功能 function startTimer(){ interval = setInterval(function(){ timer.innerHTML = minute+" 分"+second+" 秒"; second++; if(second == 60){ minute++; second=0; } if(minute == 60){ hour++; minute = 0; } },1000); }
当所有卡片都匹配正确时展示恭喜界面,显示移动次数时间和等级
function congratulations(){ if (matchedCard.length == 16){ clearInterval(interval); finalTime = timer.innerHTML; // 显示祝贺界面 modal.classList.add("show"); // 声明星级变量 var starRating = document.querySelector(".stars").innerHTML; // 显示移动、评级、时间 document.getElementById("finalMove").innerHTML = moves; document.getElementById("starRating").innerHTML = starRating; document.getElementById("totalTime").innerHTML = finalTime; //界面上的关闭图标 closeModal(); }; } // 界面上的关闭图标 function closeModal(){ closeicon.addEventListener("click", function(e){ modal.classList.remove("show"); startGame(); }); }
再次游戏功能
function playAgain(){ modal.classList.remove("show"); startGame(); } // 循环以将事件侦听器添加到每张卡片 for (var i = 0; i < cards.length; i++){ card = cards[i]; card.addEventListener("click", displayCard); card.addEventListener("click", cardOpen); card.addEventListener("click",congratulations); };
到这里我们的记忆纸牌游戏就做好了
