撲克牌排序（JS版） 編碼也快樂！

直接上程式碼，程式碼很簡單，如下：

var aColors = ['spade','heart','diamond','club'],   //牌顏色
      sCardNum = 'A123456789JQK'.split('');         //牌數字
//建立牌
function createCardObj(){
    var aCard = [];
    for(var i=0,c=-1;i<52;i++){
        i%13 == 0 && c++;
        aCard[i] = {
            n: i%13,
            value: sCardNum[i%13],
            color: aColors[c]
        }
    }
    return aCard;
}
//打亂牌的順序
function shuffle( aCard ){
    for(var j=aCard.length-1, nRnd, oTemp;j>=0;j--){
        nRnd = Math.random()*(j+1) >> 0;
        oTemp = aCard[j];
        aCard[j] = aCard[nRnd];
        aCard[nRnd] = oTemp;
    }
    return aCard;
}

//**迭代快排**
function qs(arr, fnCompare){
    var stack = [];
    stack.push([0,arr.length-1]);
    var l,r,axis,o;
    while(stack.length){
        o = stack.pop();
        l = o[0],r = o[1];
        if( l >= r )
            continue;
        axis = once(arr,l,r);
        stack.push([l,axis-1]);
        stack.push([axis+1,r]);
    }

    function once(arr,l,r){
        var axisAtLeft = true, //left right sign, default left;
            temp;
        swap(arr,l, (r+l)/2 >> 0);  //以中值為軸值
        while(l<r){
            if( axisAtLeft ){
                if( fnCompare(arr[l],arr[r]) ){
                    swap(arr,l++,r);
                    axisAtLeft = false;
                }else  r--;
            }
            else{
                if( fnCompare(arr[l],arr[r]) ){
                    swap(arr,l,r--);
                    axisAtLeft = true;
                }else  l++;
            }
        }
        return l;
    }

    function swap(arr,l,r){
        var temp = arr[l];
        arr[l] = arr[r];
        arr[r] = temp;
    }
    return arr;
}

function print( aCard ) {
    var oColorMap = {
        'spade':'#000;',
        'heart':'#f00',
        'diamond':'#900',
        'club': '#777'
    };
    for (var k = 0; k<52; k++){
        var oCurCard = aCard[k];
                var  s = '<span style="color: #fff; background-color:'+ oColorMap[oCurCard.color] +'">'+ oCurCard.color+ '--'  + oCurCard.value +'</span><br/>';
        document.write(s);
    }
};

var card = shuffle( createCardObj() );
print( qs(card, function(o1,o2){
    var mapNum = {'spade': 0,'heart': 1,'diamond': 2,'club': 3};
    return  (mapNum[o1.color]*13 + o1.n)  > (mapNum[o2.color]*13 + o2.n);
}) );

將以上程式碼拷貝到firebug中執行，便可看到結果
