js计算德州扑克牌面值的方法

本文实例讲述了js计算德州扑克牌面值的方法。分享给大家供大家参考。具体如下:
1. 代码如下:

var Poker = function(n){

    this.num = (n % 13) + 2;

    this.ch = this.num > 9 ? ("abcdef"[this.num-10]) : this.num;

    this.show = "0,1,2,3,4,5,6,7,8,9,10,J,Q,K,A".split(",")[this.num];

    this.color = "♠♥♣♦"[n / 13 | 0];

    this.toString = function(){

        return this.color + this.show;

    };

};

var z = function(arg){ //同花顺

    var a = arg,

        t = a[0];

    for (var i = 1; i < a.length; i++) {

        if( a[i].color === t.color && a[i].num === t.num + 1 ){

            t = a[i];

        }else if( i === a.length-1 && t.num === 5 && a[i].num === 14 && a[i].color === t.color){

            t = a[0];

        }else{

            return; 

        }

    };

    return "z" + t.ch;

};

var y = function(arg){ //四条

    var a = arg.map(function(p){

            return p.ch;

        }).join(""), 

        mat = a.match(/(\w*)(\w)\2\2\2(\w*)/);

    if( mat ){

        return "y"+mat[2]+mat[1]+mat[3];

    }

};

var x = function(arg){ //葫芦

    var a = arg.map(function(p){

            return p.ch;

        }).join(""), 

        mat;

    if( mat = a.match(/(\w)\1(\w)\2\2/) ){

        return "x" + mat[2] + mat[1];

    }else if( mat = a.match(/(\w)\1\1(\w)\2/) ){

        return "x" + mat[1] + mat[2];

    }

};

var w = function(arg){ //同花

    var a = arg,

        t = a[0];

    for (var i = 1; i < a.length; i++) {

        if( a[i].color === t.color ){

            t = a[i];

        }else{

            return; 

        }

    };

    return "w" + arg.map(function(p){

        return p.ch;

    }).join("");

};

var v = function(arg){ //顺子

    var a = arg,

        t = a[0];

    for (var i = 1; i < a.length; i++) {

        if( a[i].num === t.num + 1 ){

            t = a[i];

        }else if( i === a.length-1 && t.num === 5 && a[i].num === 14){

            t = a[0];

        }else{

            return; 

        }

    };

    return "v" + t.ch;

};

var u = function(arg){ //三条

    var a = arg.map(function(p){

            return p.ch;

        }).join(""), 

        mat;

    if( mat = a.match(/(\w*)(\w)\2\2(\w*)/) ){

        return "u" + mat[2] + mat[1] + mat[3];

    }

};

var t = function(arg){ //两对

    var a = arg.map(function(p){

            return p.ch;

        }).join(""), 

        mat;

    if( mat = a.match(/(\w*)(\w)\2(\w)\3(\w*)/) ){

        return "t" + mat[3] + mat[2] + mat[1] + mat[4];

    }else if( mat = a.match(/(\w)\1(\w)(\w)\3/) ){

        return "t" + mat[3] + mat[1] + mat[2];

    }

};

var s = function(arg){ //一对

    var a = arg.map(function(p){

            return p.ch;

        }).join(""), 

        mat;

    if( mat = a.match(/(\w*)(\w)\2(\w*)/) ){

        return "s" + mat[2] + mat[1] + mat[3];

    }

};

var r = function(arg){ //高牌

    return arg.map(function(p){

        return p.ch;

    }).join("");

};

var score = function(){

    var a = [].map.call(arguments, function(p){

        return new Poker(p);

    }).sort(function(p1,p2){

        return p1.num - p2.num;

    });

    console.log( a.join(",") );

    return z(a) || y(a) || x(a) || w(a) || v(a) || u(a) || t(a) || s(a) || r(a);

};

console.log( score( 50, 49, 47, 46, 48 ) ); // 同花顺

console.log( score( 36, 49, 23, 10, 48 ) ); // 四条

console.log( score( 36, 49, 23, 22, 48 ) ); // 葫芦

console.log( score( 50, 40, 47, 43, 48 ) ); // 同花

console.log( score( 50, 36, 47, 46, 48 ) ); // 顺子

console.log( score( 36, 49, 25, 22, 48 ) ); // 两对

console.log( score( 36, 49, 20, 27, 47 ) ); // 一对

console.log( score( 36, 11, 20, 27, 47 ) ); // 高牌

2. 运行效果如下图所示:
