向大家推薦一款原生JavaScript版連連看游戲，源碼下載，首頁如下圖所示：

首先看一下html的布局方式在index.html文件中：

 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 
<title>連連看</title> 
<link rel="stylesheet" type="text/css" href="css/index.css"/> 
</head> 
<body> 
<center> 
<div id="whole"> 
<div id="gamePanel" tabindex="0"> 
<div id="pieces"> 
</div> 
</div> 
<div id="gameLogo"> 
</div> 
<div id="scorePanel"> 
<span>分 數(shù)</span> 
</div> 
<div id="score"> 
<span>0</span> 
</div> 
<div id="timePanel"> 
<span>時 間</span> 
</div> 
<div id="time"> 
<span>0</span> 
</div> 
<div id="button"> 
<input id="start" type="button" onclick="Start();" value="開始"></input> 
<input id="reset" type="button" onclick="Reset();"value="重置"></input> 
</div> 
</div> 
</center> 
<script type="text/javascript" src="js/map.js"></script> 
<script type="text/javascript" src="js/piece.js"></script> 
<script type="text/javascript" src="js/game.js"></script> 
</body> 
</html> 

css文件夾下的index.css文件如下：

復(fù)制代碼代碼如下:

下面讓我們來看一下最核心的js部分實現(xiàn)代碼，js部分分為三個源文件即game.js、map.js、piece.js每一個源文件對應(yīng)一個類，其中本游戲通過game類來操縱map和圖片piece對象：
game.js代碼如下：

} 

以上是源文件的代碼,具體的實現(xiàn)代碼請關(guān)注CSDN中zhangjinpeng66下載。下面講一下連連看游戲最核心的部分，js實現(xiàn)搜索路徑。
js實現(xiàn)搜索路徑算法首先最簡單的是判斷兩個圖片能否直線到達函數(shù)代碼如下：

復(fù)制代碼代碼如下:

 
// 直線 
isStraightReach : function(piece) { 
//alert("isStraightReach"); 
if (this.isNear(piece)) { 
return true; 
} 
var a = false; 
var b = false; 
// 沿y軸方向搜索 
if (this.x == piece.x) { 
//alert("!!!!!!!!!!!"); 
for (var i = this.min(this.y, piece.y) + 1; i < this.max(this.y, piece.y); i ++) { 
//alert("this.x == piece.x: " + piece.x + "," + i); 
if (this.game.pieceMap.get(piece.x + "," + i).isPass()) { 
a = true; 
this.game.trackList.push(this.game.pieceMap.get(piece.x + "," + i)); 
continue; 
} else { 
a = false; 
this.game.trackList = []; 
return a; 
} 
} 
} 
// 沿x軸方向搜索 
if (this.y == piece.y) { 
//alert("!!!!!!!!!!!"); 
for (var i = this.min(this.x, piece.x) + 1; i < this.max(this.x, piece.x); i ++) { 
//alert("this.y == piece.y: " + i + "," + piece.y); 
if (this.game.pieceMap.get(i + "," + piece.y).isPass()) { 
b = true; 
this.game.trackList.push(this.game.pieceMap.get(i + "," + piece.y)); 
continue; 
} else { 
b = false 
this.game.trackList = []; 
return b; 
} 
} 
} 
return a || b; 
}, 

該函數(shù)實現(xiàn)了連連看判斷兩圖片是否符合連接條件的最簡單的一步,然后是拐一次彎搜索。

復(fù)制代碼代碼如下:

 
// 拐一次彎搜索 
isReach1 : function(piece) { 
//alert("isReach1"); 
var corner_1 = this.game.pieceMap.get(this.x + "," + piece.y); 
var corner_2 = this.game.pieceMap.get(piece.x + "," + this.y); 
var _this = this; 
if ((_this.isStraightReach(corner_1)) 
&& (corner_1.isStraightReach(piece)) 
&& corner_1.isPass()) { 
//alert("corner_1: " + this.x + "," + piece.y); 
this.game.trackList.push(corner_1); 
return true; 
} 
if ((_this.isStraightReach(corner_2)) 
&& (corner_2.isStraightReach(piece)) 
&& corner_2.isPass()) { 
//alert("corner_2: " + piece.x + "," + this.y); 
this.game.trackList.push(corner_2); 
return true; 
} 
return false; 
}, 

在拐一次彎搜索的函數(shù)中調(diào)用了直接搜索的函數(shù)，同樣最復(fù)雜的拐兩次彎搜索也會調(diào)用拐一次彎搜索的函數(shù)。

復(fù)制代碼代碼如下:

 
// 拐兩次彎搜索 
isReach2 : function(piece) { 
// 沿x軸正向搜索 
for (var i = this.x + 1; i < 17; i ++) { 
if (!this.game.pieceMap.get(i + "," + this.y).isPass()) { 
this.game.trackList = []; 
break; 
} else if (this.game.pieceMap.get(i + "," + this.y).isReach(piece) 
&& this.game.pieceMap.get(i + "," + this.y).isPass()) { 
this.game.trackList.push(this.game.pieceMap.get(i + "," + this.y)); 
return true; 
} 
} 
// 沿x軸搜索 
for (var i = this.x - 1; i >= 0; i --) { 
if (!this.game.pieceMap.get(i + "," + this.y).isPass()) { 
this.game.trackList = []; 
break; 
} else if (this.game.pieceMap.get(i + "," + this.y).isReach(piece) 
&& this.game.pieceMap.get(i + "," + this.y).isPass()) { 
this.game.trackList.push(this.game.pieceMap.get(i + "," + this.y)); 
return true; 
} 
} 
// 沿y軸搜索 
for (var i = this.y - 1; i >= 0; i --) { 
if (!this.game.pieceMap.get(this.x + "," + i).isPass()) { 
this.game.trackList = []; 
break; 
} else if (this.game.pieceMap.get(this.x + "," + i).isReach(piece) 
&& this.game.pieceMap.get(this.x + "," + i).isPass()) { 
this.game.trackList.push(this.game.pieceMap.get(this.x + "," + i)); 
return true; 
} 
} 
// 沿y軸正向搜索 
for (var i = this.y + 1; i < 12; i ++) { 
if (!this.game.pieceMap.get(this.x + "," + i).isPass()) { 
this.game.trackList = []; 
break; 
} else if (this.game.pieceMap.get(this.x + "," + i).isReach(piece) 
&& this.game.pieceMap.get(this.x + "," + i).isPass()) { 
this.game.trackList.push(this.game.pieceMap.get(this.x + "," + i)); 
return true; 
} 
} 
return false;
