var rawHand = [1,0,0,0,0,0,0,0,0,0,0,0,0, //clubs
0,0,0,0,0,0,0,0,0,0,0,0,0, //diamonds
0,1,1,0,1,0,0,0,0,0,0,0,0, //hearts
0,0,0,1,0,0,0,0,1,0,0,0,0];//spades
var suits = []; //array to hold representations of each suit
for (var i=0; i<4; i++) {
var index = i*13;
// commenting this line as I removed the rest of its use to simplifyy example
//var hasAce = (rawHand[i+13]);
//get a "suited" slice of the rawHand, convert it to a string representation
//of a binary number, then parse the result as an integer and assign it to
//an element of the "suits" array
suits[i] = parseInt(rawHand.slice(index,index+13).join(""),2);
}
// OR the suits
var result = suits[0] | suits[1] | suits[2] | suits[3];
// Store the result in a string for later iteration to determine
// whether straight exists and return the top value of that straight
// if it exists; we will need to determine if there is an ace in the hand
// for purposes of reporting a "low ace" straight (i.e., a "wheel"),
// but that is left out in this example
var resultString = result.toString(2);
//Show the result for the purposes of this example
alert("Result: " + resultString);
var=[]//数组以保存每件衣服的表示
对于（var i=0；i好的，直线必须包括5或10，因此如果没有一个或另一个，你可以先抛出手：
if (rawHand[3] || rawHand[16] || rawHand[29] || rawHand[42] ||
rawHand[8] || rawHand[21] || rawHand[34] || rawHand[47]) {
// do some more checks
} else {
// not a straight
}
不，这是最简单的。我前一段时间研究了扑克手的评估，我认为最快的方法是使用类似于您的方法。请参阅中的第一个结果。它使用按位运算来计算手
编辑：第一个结果，我指的是“Pokersource Poker Eval Evaluator”。您可以使用一个整数值作为卡值的位域，ace得到两个高低点。然后您将按位结束与十个可能的直线进行比较
或者使用for循环并检查五个连续的数字-实际上它们都是一样的。代码所做的几乎所有工作都是类型转换。如果刚开始时手动存储为位格式（需要>32位类型），则可以执行以下操作：
var mask = 2^13 - 1; // this will zero out all but the low 13 bits
var suits = (rawHand | rawHand>>13 | rawHand>>26 | rawHand>>39) & mask;
使用单线回路的等效值为：
var suits = [];
for(var i=0; i < 13; i++) {
suits[i] = rawHand[i] || rawHand[i+13] || rawHand[i+26] || rawHand[i+39];
}
var=[]；
对于（变量i=0；i<13；i++）{
西服，西服，西服，西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服西服；
}
这要短得多，也更容易理解
与使用逐位OR运算符相比，从逐位表示转换到逐位表示需要更多的代码和CPU时间。这个问题让我很感兴趣。我最终做得太过火了。我写了一个网页来计算任何一只手。这可能不是最有效率的，但确实有效。我只使用JavaScript（无jQuery）完成了这项工作.这是一个
