arrays - 如何在 ActionScript 3.0 中对钻石、梅花、黑桃、红心等卡片进行排序

Question

我有数组中的卡片，并且有排序按钮，但我不知道如何进行排序，例如钻石，梅花，黑桃，红心卡片想要与此卡片分开..

    var aList:Array =
            [
                {card:Globe.self.realstage.joker_mc, x:605.55, y:195.45},
                {card:Globe.self.realstage.king_mc,  x:323.80, y:298.45},
                {card:Globe.self.realstage.queen_mc, x:45.85, y:213.95},
                {card:Globe.self.realstage.a_mc,     x:605.55, y:195.45},
                {card:Globe.self.realstage.ten_mc,   x:323.80, y:298.45},
                {card:Globe.self.realstage.five_mc,  x:45.85, y:213.95},
                {card:Globe.self.realstage.two_mc,   x:605.55, y:195.45},
                {card:Globe.self.realstage.nine_mc,  x:323.80, y:298.45},
                {card:Globe.self.realstage.four_mc,  x:45.85, y:213.95},
            ];

有谁知道可以详细说明一下吗？谢谢

我建议添加一些额外的参数，比如“重量”:

 var aList:Array =
       [
           {card:Globe.self.realstage.joker_mc, x:605.55, y:195.45, weight: 11},
           {card:Globe.self.realstage.king_mc,  x:323.80, y:298.45, weight: 13},
           {card:Globe.self.realstage.queen_mc, x:45.85, y:213.95, weight: 12},
           {card:Globe.self.realstage.a_mc,     x:605.55, y:195.45, weight: 14},
           {card:Globe.self.realstage.ten_mc,   x:323.80, y:298.45, weight: 10},
           {card:Globe.self.realstage.five_mc,  x:45.85, y:213.95, weight: 5},
           {card:Globe.self.realstage.two_mc,   x:605.55, y:195.45, weight: 2},
           {card:Globe.self.realstage.nine_mc,  x:323.80, y:298.45, weight: 9},
           {card:Globe.self.realstage.four_mc,  x:45.85, y:213.95, weight: 4},
       ];

然后根据这个权重对数组进行排序:

// in descending order
aList.sort(function (c1:Object, c2:Object):int
        {
            if (c1.weight > c2.weight) return -1;
            if (c1.weight < c2.weight) return 1;
            return 0;
        });

// in ascending order:
aList.sort(function (c1:Object, c2:Object):int
        {
            if (c1.weight > c2.weight) return 1;
            if (c1.weight < c2.weight) return -1;
            return 0;
        });

如果您无法更改对象(或者由于某种原因您不想在其中添加权重)，您可以创建一个外部辅助函数:

// somewhere 
function getWeight(data: Object):int {
    switch(data.card) {
        case Globe.self.realstage.two_mc:
            return 2;
        case Globe.self.realstage.four_mc:
            return 4;

        ...

        default: return 0;
    }
}

aList.sort(function (c1:Object, c2:Object):int
    {
        if (getWeight(c1) > getWeight(c2)) return 1;
        if (getWeight(c1) < getWeight(c2)) return -1;
        return 0;
    });
