javascript实现的棋牌类

最近在学习javascript,感触良多，基本上很多以前学习过的思想都要进行打补丁了。

javascript才是真正达到了一切都是对象，一切都是数据的编程思想。不过目前各种浏览器标准不统一，所以还需要假以时日。相信以后会越来越强大。。

直接贴代码备忘

enumeration.js文件代码

/**
* Created by watsy on 13-12-4.
*/

function inherit(p) {
if (p == null) {
throw new TypeError();
}
if (Object.create) {
return Object.create(p);
}
var t = typeof p;
if (t !== "object" && t !== "function") {
throw new TypeError();
}
function F() {}
F.prototype = p;
return new F();
}

function enumeration(namesToValues) {
var enumeration = function() { throw "Can't Instantiate Enumerations";  };

var proto = enumeration.prototype = {
constructor:    enumeration,
toString:   function()  {   return  this.name;  },
valueOf:    function()  {   return  this.value; },
toJSON:     function()  {   return  this.name;  }
};

enumeration.values = [];

//
for (name in namesToValues) {
var e = inherit(proto);
e.name = name;
e.value = namesToValues[name];
enumeration[name] = e;
enumeration.values.push(e);
}

enumeration.foreach = function (f, c) {
for (var i = 0; i < this.values.length; i++) {
f.call(c, this.values[i]);
}
};

return enumeration;
}

Card.js 代码

/**
* Created by watsy on 13-12-4.
*/

//include("enumeration.js");

function Card(suit, rank) {
this.suit = suit;
this.rank = rank;
}

Card.Suit = enumeration({Clubs:1, Diamonds:2, Hearts: 3, Spades: 4});
Card.Rank = enumeration({Two : 2, Three: 3, Four: 4, Five: 5, Six: 6,
Seven: 7, Eight: 8, Nine: 9, Ten: 10, Jack: 11, Queen: 12, King: 13, Ace: 14});

Card.prototype.toString = function() {
return this.rank.toString() + " of " + this.suit.toString();
};

Card.prototype.compareTo = function (that) {
if (this.rank < that.rank) return -1;
if (this.rank > that.rank) return 1;
return 0;
};

Card.orderByRank = function (a, b) {    return a.compareTo(b);  };

Card.orderBySuit = function (a, b) {
if (a.suit < b.suit)    return -1;
if (a.suit > b.suit)    return 1;
if (a.rank < b.rank)    return -1;
if (a.rank > b.rank)    return 1;
return 0;
};

function Deck() {
var cards = this.cards = [];
Card.Suit.foreach(
function (s) {
Card.Rank.foreach(
function (r) {
cards.push(new Card(s, r));
}
);
}
);
}

Deck.prototype.shuffle = function () {
var deck = this.cards, len = deck.length;

for (var i = len - 1; i > 0; i--) {
var r = Math.floor(Math.random() * (i + 1)), temp;
temp = deck[i], deck[i] = deck[r], deck[r] = temp;
}
return this;
};

Deck.prototype.deal = function (n) {
if (this.cards.length < n)  throw "Out ot cards";
return this.cards.splice(this.cards.length - n, n);
};

调用代码

var deck = (new Deck()).shuffle();
var hand = deck.deal(13).sort(Card.orderBySuit);
console.log(hand.toString());
