Flex :: Looping Through Object Property Names In Actionscript?
Apr 22, 2010
I have a dynamic class that I have created
public dynamic class SiteZoneFileUploadVO
{
public var destination:String = "sitezone";[code]...........
when I try to iterate over this object's property names it only iterates the dynamically added properties.
parameters.dynVar= "value";
for(var name:String in parameters)
{
Even though the object has all the properties equal to a value (ive checked this in the debugger) the only property name that will be traced is dynVar.How can I iterate over all the property names and not just the dynamically added ones?

I need to create variable object property names for use with the data grid component.
This works: data = new Object(); data.some_name = "the data";
But this does not: data = new Object(); colName = "some_name"; data[colName] = "the data";

Given an XML object: <column label="Name" datafield="userName" width="70" />, how do I extract the NAME of the properties rather than the values, e.g. ["label", "datafield", "width"]?
ActionScript Code:
for (var pname:* in column.@*)
{
trace(pname);
}
Returns "0", "1", "2", and "for each" returns "Name", "userName", "70".
What I really want is "label", "datafield", and "width", hopefully without the overhead of actually parsing the xmlString.

Let's say I have a class which looks like this :
public class MyClass
{
public var attribute1;
public var attribute2;
}
and I'd like to get attribute1 and attribute2 as strings. I tried this :
var test:MyClass = new MyClass();
for (var key:String in test)
{
trace(test[key]);
}
but it does not work, it never goes in the loop. How can I do what I want to do ?

How do you use variables to access Object attributes? Suppose I have an Object declared as follows,
var obj:Object = new Object;
obj.Name = "MyName";
obj.Age = "10";

When I want to loop through instance names like: "tile1", "tile2" etc. I use a code like this:
PHP Code:
for(var i=0;i<=10;i++){
this["tile"+i]._x=300;}
But when I put these MC's inside an MC (which I've named: "ground") for some reason this code:
PHP Code:
for(var i=0;i<=10;i++){
_root.ground.this["tile"+i]._x=300;}
doesn't work. Is there a way to loop through all the objects inside a movieclip without giving each one an instance name?

My problem is to find out the object which owned my property... for example:
My Class :
public class MyClass{

Now, I add my Group to another UIComponent. Next step in Class XYZ I wan't to get my MyClass Object ... but I can only see the var myGroup
public class XYZ {
...
public function getObject(group:Group):MyClass {
return group.????;
}
...
}

<mx:Canvas id="maincanvas" backgroundColor="7000" width="100%" height="100%">
<mx:TextArea backgroundAlpha="0"/>
</mx:Canvas>
However if I try creating a new textarea object via:
var textarea:TextArea = new TextArea ();
textarea.backgroundAlpha = 0;
maincanvas.addChild(textarea);
flex throws the error :
1119: Access of possibly undefined property backgroundAlpha through a reference with static type mx.controls:TextArea.

I have a dynamic Actionscript class as follows: public dynamic class Foo {....} In my code I (may) add some properties to it: myFoo["myNewDynamicProp"] = "bar"; Elsewhere in my code, given an instance of class Foo, how can I determine if that dynamic property has been added already without throwing an expensive exception?

I'm trying to convert an MXML component to an ActionScript Class. The component consists of a Form with a TextInput, TextArea, and two buttons - Save and Cancel, and a Validator for the TextInput, and other logic to handle events that occur. This component is currently extended by several other components. Now, in the MXML component binding the TextInput text property to a property in an Object was very easy:
<mx:TextInput text="{_itemToEdit.name}" />
But in ActionScript, I'm creating the TextInput and setting the text property before the Object is set, and the TextInput is not being updated:
public var itemToEdit:Object = {};
private var nameInput:TextInput = new TextInput();
public function MyClass() {
nameInput.text = itemToEdit.name;
}
How can I make sure that the TextInput text property is bound to the specified property in the Object?

I'm trying to assemble a header object for an api request. One of the headers is 'Content-Type'. The hyphen is causing a compile error. Flex is giving me:
1050 - Cannot assign to a non-reference value.
I find it spiteful that they enjoy the use of a hyphen in the error message while I hang my head and come here for answers.

I am using shared object to share data between two users. First user connect to shared object and set some value in shared object. Please consider that second user has not connected with the shared object yet.Now when second user connects to the server and try to get that property set by first user, he could get shared object but could not get properties of Shared object set by first user. I observed few times that Second user can get these properties within "Sync" event between two users. But I would like to get these values for Second user in any stage (i.e. in load event etc.). Whenever Second user tries to get the property of Shared object, the object will reset the actual property value and then return reset value.
1) Is there any way to get all the properties of shared object before sync event called, as I want to get it immediately when second user connect to the application and perform next task based on the values stored in shared object.
2) Is it possible for second user to check whether any property has been set by first user? So that second user can use the property instead of reset it.

I want to get my flv file looping within the swf. I've used the FLVPlayback Component. I've given the flv file the instance name of "vid". Actionscript is as follows:
import fl.video.*;
vid.addEventListener(VideoEvent.COMPLETE, rewind);
function rewind(eventObject:VideoEvent):void {
vid.autoRewind = true;
vid.play();
}
The error message I get at runtime is: 1119: Access of possibly undefined property COMPLETEthrough a reference with static type class.

I'm new to flex and actionscript. I'm trying to create a small flex app that has multiple states, but if I have nested containers, it looks like some of the objects are not getting initialized when I expected them to be, even when I have the creationPolicy set to "all."I've reduced the issue to a small example, with a commented block showing when it does work.sing the existing code, I get this error: "TypeError: Error #1009: Cannot access a property or method of a null object reference at main/init()" and the event handlers are not installed.If I instead use the commented block, which has the Panel and VBox elements removed, it does work.I know I could add a click attribute to the mxml elements, but this is just a simplified example, and I'm more interested knowing why the objects are not initialized when the app loads.

I have an object which is assigned a number of properties:
var project_array:Array = [];
var slideObject:Object = {
project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
