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:
