使用js实现黑白翻转棋

黑白翻转棋：黑白棋，又叫翻转棋（Reversi）、奥赛罗棋（Othello）、苹果棋或反棋（Anti reversi）。

　　　　　　黑白棋在西方和日本很流行。游戏通过相互翻转对方的棋子，最后以棋盘上谁的棋子多来判断胜负。  

关于使用JavaScript实现黑白翻转棋的代码有很多，不过整体算法大致相同

游戏规则 
如何玩 :

点击棋盘落子。 


如何赢 :

使自己颜色棋子最多。 


游戏目的 ：

游戏通过相互翻转对方的棋子，最后以棋盘上谁的棋子多来判断胜负。 


下棋方法 :

开始时在棋盘正中有两白两黑四个棋子交叉放置，黑棋总是先下子。 

下子的方法 :

把自己颜色的棋子放在棋盘的空格上，而当自己放下的棋子在横、竖、斜八个方向内有一个自己的棋子，则被夹在中间的全部翻转会成为自己的棋子。并且，只有在可以翻转棋子的地方才可以下子。 

胜负判定条件 :

如果玩家在棋盘上没有地方可以下子，则该玩家对手可以连下。双方都没有棋子可以下时棋局结束，以棋子数目来计算胜负，棋子多的一方获胜。 

在棋盘还没有下满时，如果一方的棋子已经被对方吃光，则棋局也结束。将对手棋子吃光的一方获胜

下面就是代码，这个代码有点长，还没有详细的去研究一下具体实现，有时间看看
