Flex: Access member variable by using a variable in the name

How can I access the member variable of an object by using a variable in the name.

Example:

Entries Object has properties 1, 2, 3, 4, 5. Normally I would access them by

var i : int = Entries.1;
var i : int = Entries.2;

However, if I have a loop

for (var j : int = 1; j < 6; j++){
  trace(Entries[j]);
}

does not work.

 Entries.(j)
 Entries.j

neither.

What's the way to go?

Entries.hasOwnProperty("j")

also does not work to check if the member exists.

Thanks!

Entries.hasOwnProperty("j")

does not work because you're sending it "j" as a string, you need to convert the integer variable j to a string, therefore representing the number you are looking for. Eg:

Entries.hasOwnProperty(j.toString());

So to extract the property from your object, you can do:

for(var j:int = 1; j < 6; j++)
{
    trace(Entries[j.toString()]);
}
