通过动态分配名称在对象中创建不同数量的参数？

Question

我如何编写一个构建此数组的过程，以便我可以选择尽可能多的参数名称，例如KBP？我想了？

public var expenses:ArrayCollection = new ArrayCollection([
    {Impact:"A", KBP1:1, KBP2:0, KBP3:0, KBP4:0 },
    {Impact:"B", KBP1:0, KBP2:0, KBP3:0, KBP4:0 },
    {Impact:"C", KBP1:0, KBP2:2, KBP3:3, KBP4:0 },
    {Impact:"D", KBP1:0, KBP2:0, KBP3:0, KBP4:8 },
    {Impact:"E", KBP1:0, KBP2:0, KBP3:0, KBP4:0 }
]);

Answer 1

如下所示：

var arrayLength:int = 100;
var kbpsLength:int = 50;
var expensesArray:Array = [];
for (var i:int = 0; i < arrayLength; i ++)
{
    var item:Object = {Impact:"A"};
    for (var j:int = 0; j < kbpsLength; j ++)
    {
        item["KBP" + (j + 1)] = 0;
    }
    expensesArray.push(item);
}
var expenses:ArrayCollection = new ArrayCollection(expensesArray);

Answer 2

这是我对你的问题的理解。如果这不是您想要的，请随时澄清。

var expenses:ArrayCollection = new ArrayCollection();

(loop conditions?)
{
    var item:Object = {};
    item.Impact = "A";
    item.KBP1 = 0;
    item.KBP2 = 0;
    item.KBP3 = 0;
    item.KBP4 = 0;
    item.KBP5 = 0;
    ...

    expenses.addItem(item)
}
