Question

Please see code below. I will have a bunch of elements, that I want to run whatever “formula” refers to, for that element. In the code, where it says, “this works”, it works as expected. However I need to fire off these formulas, without naming “firstElement” explicitly. Even though the nested for loop is a little clunky, I think it should work, but it causes the error listed below. How can I fire off the formulas, without naming the elements explicitly? Thanks!

    var test:Object = { 
        element:
        [
            { "firstElement":
                {   
                    formula:myFunction
                }
            }
        ]
    }// end test object


    public function RunThisFunctionFirst() {

        test.element[0].firstElement.formula();//this works 

        for (var index in test.element){
            for (var object in test.element[index]){
                trace ("object " + object);// traces "firstElement", as expected
                object.formula()// this causes error: Error #1006: value is not a function.
            }
        }
    }

    function myFunction (){
        trace ("my function called");

    }

Regarding the outer loop, element is an array, not an object, so you want to use for(;;) not for in.

Regarding the inner loop, object is the string "firstElement" not an object.

for (var i:int=0; i < test.element.length; i++)
{
    for (var key:* in test.element[i])
    {
        trace("key " + key);
        var object:* = test.element[i][key];
        trace("object " + object);
        if(typeof object === "object" && object.hasOwnProperty("formula"))
            object.formula();
    }
}
