as3关联值对象中的值的数组

Question

我有一些看起来像

的东西

aInt[0] = {pk:'1', other:'this', otherother:'that'};
aInt[1] = {pk:'1', other:'this2', otherother:'that2'};
aInt[2] = {pk:'2', other:'thisA', otherother:'thatA'};
aInt[3] = {pk:'3', other:'thisB', otherother:'thatB'};

我想把它变成

aNew[0] = [1 [{other:'this', otherother:'that'},
              {other:'this2', otherother:'that2'}];
aNew[1] = [2 [{other:'thisA', otherother:'thatA'}];
aNew[2] = [3 [{other:'thisB', otherother:'thatB'}];

或其他相似之处。也许结果上的语法不正确，但我希望我的意图很明确。随意编辑语法。我想基于我拥有的对象数组中的pk字段的值来关联结果集。在as3

提前致谢。

Answer 1

for each (var obj:Object in aInt) {
    if (aNew[obj.pk] == undefined)
        aNew[obj.pk] = [];
    aNew[obj.pk].push(obj);
}
