這篇文章主要介紹了js面向?qū)ο笾绾螌?shí)現(xiàn)拼圖游戲,小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧

一、html代碼

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>拼圖小游戲</title>
<style>
body,td { margin:0; padding:0; }
#begin { display:block; margin:20px auto; }
table { margin:80px auto; background:#fff; border:10px solid pink; }
td { width:100px; height:100px; border:1px solid #ccc; cursor:pointer; background:url(img.jpg) no-repeat; }
</style>
<script src="js.js"></script>
<script>
window.onload = function(){
	var thisGame = new PinTuGame('begin');
}
</script>

</head>

<body>
<button id="begin">開始</button>
</body>
</html>

二、js代碼

function PinTuGame(id){
	var that = this;
	this.oBtn = document.getElementById(id);
	this.oTable = document.createElement('table');
	this.oTbody = document.createElement('tbody');
	this.aTd = null;
	this.aTdMsg = [];	//用于存儲每個(gè)圖片的信息
	this.num = 0;	//用于判斷拼圖是否完成
	this.oTable.cellSpacing = '0';
	
	this.createElem();	//初始化游戲界面
	this.oBtn.onclick = function(){
	for(var i = 0; i<that.aTd.length; i++){
	that.aTd[i].style.opacity = 1;	
	}
	this.innerHTML = '重新開始';
	that.aTd[that.aTd.length-1].style.opacity = 0;
	
	var iAlpha = 100;
	var sp = -10;
	var timer = setInterval(function(){
	iAlpha += sp;
	that.oTbody.style.opacity = iAlpha / 100;
	
	if(iAlpha <=0) { sp = -sp; that.randomElem();}

	if( rows[arr[i][0]].cells[ arr[i][1] ].style.opacity == '0' ){
