Question

How would I write a procedure that would build this array such that I could choose as many parameter names such as KBP? I wanted?

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

Something like the following:

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);
