Why will this code only trace strings?

Question

The following code randomizes the array "doors". It works fine if the array is strings. However,

if I remove the quotation marks, it traces "[object Symbol1_1]" instead.

var doors:Array = [red_button, blue_button,yellow_button];

var randomDoors:Array = new Array(doors.length);

var randomPos:Number = 0;

for (var i:int = 0; i < randomDoors.length; i++)

{

randomPos = int(Math.random() * doors.length);

randomDoors = doors.splice(randomPos, 1)[0];

}

trace (randomDoors);

Tracing (randomDoors.name) returns the statement "undefined". How can I trace "doors" without converting the elements to strings?

the array class doesn't have a name property. when you use trace(randomDoors.name), you're asking flash to find the name property of that array.

so, either use:

for (var i:int = 0; i < randomDoors.length; i++)

{

trace(doors.name);

}

or create your own function or class to do what you want so you don't have to repeatedly create a for-loop to trace what you want.

assuming those doors elements have names, loop through that array and trace each elements name.
