Actionscript 2 :: Function's Local Variable Through A Concatenated Variable String?

Mar 7, 2012

how you would target a function's local variable through a concatenated variable string.For example:

var txt = "Hello World";
function testing(msg) {
var test1 = msg;[code].........

I'd expect the trace to be "Hello World" but rather is given "undefined". So if variables created outside functions are created on the main timeline, where are local function variables created and how would you access them?

ActionScript 3.0 :: Declaring A Variable In A Function: Either The Function Or The EventListener - Doesn't Work

Nov 27, 2009

I have a set of Cue Points in an FLV I'm playing. It's an interactive quiz, so the idea is that flash will change a variable, theAnswer, to a different letter depending on which question it is. The answer to question 1 is B, question 2 is D, etc. Either the cue point event listener isn't working, or else it is working and Flash isn't declaring the variables. 1120: Access of undefined property theAnswer. I literally can't find a single problem with my code. I have an almost identical Event Listener further down which works.

ActionScript 3.0 :: Declaring A Variable Inside A Function To Use Outside The Function?

May 5, 2011

I want to create a vector, then call a function that populates that vector with arrays. Fine. The only catch is the function itself will declare new array variables to put into the vector, but are these new array variables private to the function only?e.g. something like this

ActionScript Code:
public var vec:Vector.<Array> = new Vector.<Array>();
private function populateVec():void {

[code]....

Is this "kosher"? a was declared in the private function but added to something outside the function..?

ActionScript 2.0 :: Use A Variable In The Name Of A Function?

Aug 14, 2004

I'd like to have a number of different functions named something like: "function1", "function2", "function3", all the way up to function100.

I'd like to be able to call them by adding the the number as a variable. For example:

type = 2;
function+type();

Which would call function2. I'm trying to avoid a huge if/else statement by only calling the functions I need.

Can a function be called if part of the function name is a variable? Is there another way to join "function" with the variable and then call it?

ActionScript 2.0 :: Take A Variable Out Of A Function?

Mar 22, 2007

I have a array that gets passed straight into this function

Code:
function handleResult(re : ResultEvent)
{
QuestionSet = re.result;
trace(QuestionSet[0]['Question']);
}

Now I wan't to take the 'QuestionSet' array out of this function and expose it on the first frame (or on the _root. domain) so I can call it from OUTSIDE the function. So for example:

Code:
function handleResult(re : ResultEvent)
{
QuestionSet = re.result;

[Code]....

I can't just return the array because first i need to PUT IN the array in order to return it from the function which defeats the purpose!

to access it directly:

using some kind of bracket notation?
