Extracting numeric values from concats

[JediMind]

Yo.

Is there a way to extract a numeric value from my variable using concatination.


var i:Number = 1;
var test1value:Number = 3;

trace(this["test"+i+"value"]);

I tried all kinds of tricks but I just can get the string name of the variable instead of the value it holds.
Anyone?

hi,

I don't understand the "extract" part.
Would it be just

var i:Number = 1;
var test1value:Number = 3;

trace("test"+i+"value");

If not, provide more details please.

"extract" is just my fancy name for getting the value the variable holds.

However,


trace("test"+i+"value");
and trace(this["test"+i+"value"]);

gives the same result, the name of the variable and not the number. Can you think of a way to get the value of the variable out?

[nunomira]

var i:Number = 1;
var test1value:Number = 3;

trace(this["test"+i+"value"]); // 3
trace("test"+i+"value"); // test1value

They don't give the same result.

The first evaluates the string and gives the value the variable hold: 3 (number)
The second concatenates the string and gives it: test1value (string)

is the variable test1value in your situation actually a property of "this"?

this["test"+1+"value"] == this.test1value

try creating the variable in your class variable definitions, or in a dynamic class (or a frame script) specify it as this.test1value=3 instead of scoping it locally with var test1value=3.

Doh!
this["test"+1+"value"] worked.

and I have that in my snippet and still it doesnt work when I do it.
So it gotta be something else.
I guess you get codeblind after a while, I'll keep searching bugs.

thx.

I think there is no revers script to get the variable name.

var x=100;

If you provide x, you will get 100.
But if you provide 100 and ask for x, you will not.

But there should be something.

Hope for the best...

Is that you are talking about?
