HTML仅有一个id为game的div,并且没有编写css样式,只需要在img文件夹中放置一个图片文件就行,此处我放置的是LOL皇子的图片,图片名为'lol.png'
<div id="game"> </div>
以下为实现后的效果图
多的不说,直接上js代码
var gameConfig = { width: 500, height: 500, rows: 3, //行数 cols: 3, //列数 isOver: false, //游戏是否结束 imgurl: "img/lol.png", //图片路径,注意:相对的是页面路径 dom: document.getElementById("game") //游戏的dom对象};//每一个小块的宽高gameConfig.pieceWidth = gameConfig.width / gameConfig.cols;gameConfig.pieceHeight = gameConfig.height / gameConfig.rows;//小块的数量gameConfig.pieceNumber = gameConfig.rows * gameConfig.cols; var blocks = []; //包含小方块信息的数组 function isEqual(n1, n2) { return parseInt(n1) === parseInt(n2);} function Block(left, top, isVisible) { this.left = left; //当前的横坐标 this.top = top; //当前的纵坐标 this.correctLeft = this.left; //正确的横坐标 this.correctTop = this.top; //正确的纵坐标 this.isVisible = isVisible; //是否可见 this.dom = document.createElement("div"); this.dom.style.width = gameConfig.pieceWidth + "px"; this.dom.style.height = gameConfig.pieceHeight + "px"; this.dom.style.background = `url("${gameConfig.imgurl}") -${this.correctLeft}px -${this.correctTop}px`; this.dom.style.position = "absolute"; this.dom.style.border = "1px solid #fff"; this.dom.style.boxSizing = "border-box"; this.dom.style.cursor = "pointer"; // this.dom.style.transition = ".5s"; //css属性变化的时候,在0.5秒中内完成 if (!isVisible) { this.dom.style.display = "none"; } gameConfig.dom.appendChild(this.dom); this.show = function () { //根据当前的left、top,重新设置div的位置 this.dom.style.left = this.left + "px"; this.dom.style.top = this.top + "px"; } //判断当前方块是否在正确的位置上 this.isCorrect = function () { return isEqual(this.left, this.correctLeft) && isEqual(this.top, this.correctTop); } this.show();} function init() { //1. 初始化游戏的容器 initGameDom(); //2. 初始化小方块 //2.1 准备好一个数组,数组的每一项是一个对象,记录了每一个小方块的信息 initBlocksArray(); //2.2 数组洗牌 shuffle(); //3. 注册点击事件 regEvent(); function regEvent() { //找到看不见的方块 var inVisibleBlock = blocks.find(function (b) { return !b.isVisible; }); blocks.forEach(function (b) { b.dom.onclick = function () { if (gameConfig.isOver) { return; } //判断是可以交换 if (b.top === inVisibleBlock.top && isEqual(Math.abs(b.left - inVisibleBlock.left), gameConfig.pieceWidth) || b.left === inVisibleBlock.left && isEqual(Math.abs(b.top - inVisibleBlock.top), gameConfig.pieceHeight)) { //交换当前方块和看不见的方块的坐标位置 exchange(b, inVisibleBlock); //游戏结束判定 isWin(); } //交换当前方块和看不见的方块的坐标位置 // exchange(b, inVisibleBlock); // //游戏结束判定 // isWin(); } }) } function isWin() { var wrongs = blocks.filter(function (item) { return !item.isCorrect(); }); if (wrongs.length === 0) { gameConfig.isOver = true; //游戏结束,去掉所有边框 blocks.forEach(function (b) { b.dom.style.border = "none"; b.dom.style.display = "block"; }); } } function getRandom(min, max) { return Math.floor(Math.random() * (max + 1 - min) + min); } function exchange(b1, b2) { var temp = b1.left; b1.left = b2.left; b2.left = temp; temp = b1.top; b1.top = b2.top; b2.top = temp; b1.show(); b2.show(); } function shuffle() { for (var i = 0; i < blocks.length - 1; i++) { //随机产生一个下标 var index = getRandom(0, blocks.length - 2); //将数组的当前项与随机项交换left和top值 exchange(blocks[i], blocks[index]); } } function initBlocksArray() { for (var i = 0; i < gameConfig.rows; i++) { for (var j = 0; j < gameConfig.cols; j++) { //i 行号,j 列号 var isVisible = true; if (i === gameConfig.rows - 1 && j === gameConfig.cols - 1) { isVisible = false; } var b = new Block(j * gameConfig.pieceWidth, i * gameConfig.pieceHeight, isVisible); blocks.push(b); } } } function initGameDom() { gameConfig.dom.style.width = gameConfig.width + "px"; gameConfig.dom.style.height = gameConfig.height + "px"; gameConfig.dom.style.border = "2px solid #ccc"; gameConfig.dom.style.position = "relative"; }} init();
