Question

I am trying to copy a 2D array in a temporary array to a permanent one. The problem is that the array it’s trying to copy to is dynamic.

I was looking for a way to get string (the new arrays name) to act as the arrays actual name, not the value of any part of the array. I have looked around and this is roughly what I came to:

(this["dynamicArrayName"]) = tempArray;

or

(this[variableWithName]) = tempArray;

(not even sure thats the best way to copy a 2D array).

However, this doesn’t work :(. It comes up with so many errors (not syntax).
If there is some way to turn string into an Arrays/Variables name, it would be fantastic to know about.

Just drop the parens in your first example.

function someFunc():void {
    var temp:Array = [1,2,3];
    this['someArr'] = temp;
}

trace(this['someArr']);
// will output "undefined"

someFunc();
trace(this['someArr']);
// will output "1,2,3"
