JavaScript实现德州扑克牌型识别与面值计算

JavaScript实现德州扑克牌型识别与面值计算

本文详细介绍了一种使用JavaScript计算德州扑克牌面值并识别牌型的实现方案。该示例代码可供开发者参考，用于前端扑克游戏或相关逻辑处理。

核心代码实现与逻辑解析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
