ActionScript 3.0 :: How To View Variable Outside A Function
May 29, 2010
How can I make variable be visible inside of a function in AS3. In php the technique is to use global declaration to input the variable from the global scope into the function's local scope, so you can use and modified it and this is going to change the content of that variable.
I want to dos the same thing in flash. I have a variable outside a function, I want to see it inside the function, modify it and the use it outside the function after words

I have a headerbar.mxml that is displayed when user swipes_down in my app. The headerbar.mxml contains a button component I want to run an erase() in the main application window. The main application is a drawing app that contains an erase(). I just don't know how to call a function from another mxml view file. I thought it would be something like
click="{mainwindow.drawPanel.erase()}";
EDIT:
protected function onColorChange(event:List):void{

I have been working on a Flex Mobile application using Flash Builder 4.6. I have 2 mxml 'views' in my project. In one mxml file, i have a function that grabs xml data. In my other mxml file, I have a refresh button that when depressed is suppsosed to call the function in the first mxml file in order to once again grab the xml data. I dont know how to call that function from outside the mxml file it is housed in. [UPDATE #2]* I thought I should share some more details about my issue.
It is a reddit client mobile app. It fetches the feeds, etc. In my main view called RedditReaderHomeView.mxml, I am using a splitViewNavigator spark component to house two other views like so:

I am learning Flex and trying to make a simple RPG to practice. I am using view states to change between screens. right now I have a HomeView.mxml which displays my character information, InventoryView.mxml which shows my inventory items, and EquipmentView.mxml which shows the equipped items. They each have their respective view states.
in my main mxml file, i create a global variable for the character and an ArrayCollection of items in the game. it creates 2 labels in mxml for Inventory and Equipment and when i click on the label it calls a click handler which sets currentState="EquipmentView" or "InventoryView" This works and the state changes and the respective views are shown properly. My problem is in my EquipmentView state. When i enter the state the first time, it has a creationComplete function which displays images for my equipment and sets a click handler. when i click the item, it "unequips" it and removes it from the equipment list and removes the image. this also works fine, but when I go to my inventory view and "equip" an item and return to the EquipmentView, the image does not show. I have a label which counts the length of my equipmentList variable and that is accurate when i switch views, but i cant get the image to display again. Is there a way to call my displayEquippedItems() function (which is originally called on creationComplete) when the view is changed?

Coming from Robotlegs/PureMVC, I am pretty familiar with the concept of the view mediator, i.e. a component that pretty much listens to events/requests coming from the "dummy" view and makes a further request, sends an application-wide signal/event, executes a command, etc, based on the request from the view. Can the host component idea introduced in Flex 4 be considered a the same as a mediator? The only thing that slightly bothers me is that host components are still considered views, because they extend SkinnableComponent or any of the classes that further inherit from it. In my view, the mediator should be completely left out of view logic.
Nevertheless, I do not want to write a skin, a host component, and a view mediator for that host component, because that would be quite an overhead, and would lead to more complexity rather than abstraction.Should I use host components as mediators, and put application-level logic there, for instance application level event dispatching?

I'm about to have to write a web page/app that will serve the agenda for circa 100 people on a page. One line per person, one column per day with 3 clickable zones in each cell. In HTML, the page is way complex for the browser to load quick and there is no possibility to click on a border between 2 cells to for example split an event that spreads among several cells. So I search an not too overkilling technology to render this kind of view. I begun with a PHP generated HTML page but the number of elements in the page make the mouse move jerky.
Moving to JAVA would give me better performances regarding the reuse of the generator of the view but it will still be an HTML page. So, here is my question: do you think that going forward with JAVA and its graphical capability is the simple solution or is Flash a better option for this part of a Web App? I'm afraid of the code I'll have to write in JAVA to handle the GUI presentation as well as the events generated by the 1000's cells plus borders of the page. In Flash, the graphical part seems simpler even if the actions handling is still huge.

I'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.

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?

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.

I have one .mxml file (the Application) with a ViewStack (with 4 views) and a ControlBard, obviously I can change the views with it, but what I want to do is: in view #1 I have an image which I want to convert to a "hyperlink", so when I click it I go to View #2, is this doable? Also I would like to pass somehow some data (like a String) to that View #2 (lets say the it's a user avatar I click so I want to go to the second view which will show me his profile, that's why I need his name/id).

My problem is that when I try to pass an object from the navigator.pushView(view, dataobject), I can't figure out how to access the dataobject from actionscript. I can access {dataobject.property} from MXML easily, but I want to set a variable in the new view to the passed dataobjects property.

in flash, I encounted a source file that is cropped and I cannot move it, is there some sort of cropped view in flash I dont know about? I cannot find anyinformation about it, it has rulers displayed as far as I remember.
Basically you cannot move in the file to edit anything viewpoint wise, everything outside of the movie area is invisible and not there? As if cropped.

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..?

I have created an actionscript function which stops an animation on a specific frame which works fine. I have then loaded in a php file with a variable which will contain the number for the frame i want the animation to stop on. This has loaded in fine and i have loaded it in a function. what i cant seem to do is to get the variable into the function which tells the animation to stop playing.
here is my code:
//load variablesvarReceiver = new LoadVars(); // create an object to store the variablesvarReceiver.load("http://playground.nsdesign6.net/percentage/external.php");//load variables

Can't seem to get the value of myXML outside the function, despite being declared outside. The data loads and traces correctly inside the function.
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("flightPlannerBoard.xml"));
var myXML:XML;
// Check XML data fully loaded
myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
myXML = new XML(e.target.data);
//trace(myXML);
} trace(myXML);

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?
