【问题描述】：

我有数组中的卡片，并且我有排序按钮，但我不知道如何进行排序，例如钻石、梅花、黑桃、心形卡片想要与这张卡片分开..

    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,
            ];

谁知道，请详细说明一下。谢谢

【参考方案1】：

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那里增加权重），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;
    );

【参考方案2】：

您可以像@Nbooo 所说的那样添加额外的参数，并像这样使用Sort 和SortField：

var sortField : SortField = new SortField();
sortField.name = "weight";
sortField.numeric = true;

var sort: Sort = new Sort();
sort.fields = [sortField];

this.aList.sort = sort;
this.aList.refresh();
