This article examples describe how to calculate the face value of Texas Hold'em cards by JS. Share it for your reference. The details are as follows:
1. The code is as follows:
Copy the code as follows: 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){ //Flush
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){ //Four items
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){ //Gourd
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){ //Synonyms
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){ //Shizi
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){ //Three items
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){ //Two pairs
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){ // A pair
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){ //High card
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 ) ); // Flush
console.log( score( 36, 49, 23, 10, 48 ) ); // Four items
console.log( score( 36, 49, 23, 22, 48 ) ); // Gourd
console.log( score( 50, 40, 47, 43, 48 ) ); // Same flower
console.log( score( 50, 36, 47, 46, 48 ) ); // Shunzi
console.log( score( 36, 49, 25, 22, 48 ) ); // Two pairs
console.log( score( 36, 49, 20, 27, 47 ) ); // A pair
console.log( score( 36, 11, 20, 27, 47 ) ); // High card
