actionscript variable name in another variable

Question

ok, I have been trying to solve this myself for the better part of three days, with no luck. Here is a sample of code:

var text1:TextInput = new TextInput();
text1.text = "67"
for (var i:int = 1; i < 49;i++) {
    var test:int = int(["text" + i].text);
    trace(test);
}

this should output "67" but it only outputs "0". I have tried several combinations of bracket placement, with no luck. If I change the line:

    var test:int = int(["text" + i].text);

to this:

    var test:int = int(["text" + i] + ".text");

when i check the value in the debugger, it shows me that ["text" + i] + ".text" yields "text1.text", but not the string "67". any help would be greatly appreciated.

Thanks

Wes

You did almost right but you need to use this before square brackets where you put your computed string. Once you do, it'll work. — Vesper

And what about using this keyword:

for (var i:int = 1; i < 49;i++) {
    var field:TextInput = this["text" + i];
    var test:int = int( field ? field.text : 0);
    trace(test);
}
