I`m little stuck here, pretty simple solving problem I believe.
I`m trying to use this JSON library for my project.[code]...
I have a pure ActionScript 3 problem, but the simplified test case I've prepared is in Flex 4 for better visibility (the source code is below): Since Flash Player 11 / AIR 3 support JSON natively, I've decided to move a multiplayer game, which used XML for communicating with server, to JSON. But I have a frustrating problem, that given two Objects like

I am working on a information visualization project that involves visualizing json data from online forums. The problem that I'm having is that I'm not able to access all of the values of elements the json. Here is my Schema:
[{"course": "compsci 101",
"forums": {
"forum": {
"forum_title": "Week 11 - Cable and the Specialization of Television",
"forum_word_count": "1000",
[Code] .....
I tested and the json is valid but when I run it with this code it only is able to pull the last value (Week 2 Discussion 1 - Cable and Broadcast Television).
for (key in tuples) {
trace("forum title: "+ tuples[key].forums.forum.forum_title);
}
So, my question is, why isn't it tracing all of the values for the forum title? and what do I need to change to access those values?
I'm trying to access a nested json array
var jsonResponse:Object = JSON.decode(response);
var foo:Object = JSON.decode(jsonResponse.nested);
var bar:Array = foo as Array;
When i inspect foo - its an object with about 50 children objects.I can read the properties of the children objects. However, when i cast foo as an Array it comes back null.I'd prefer to not iterate over each object and push it into an array.
I have the following JAX-RS service.[code]...
The JAX-RS service receives the request and respond successfully with some dummy response, but I have no access to the request.data field.
How do I access the data of the request message (which is {"type":"get_configuration","data":"some data"} in this particular example)? I think that I'm supposed to add some parameters to the handleMessage method like
public SomeResponse handleMessage(Object message) {...
but this does not work at all. The request got 415 response.
Created an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData);
public function getGridData():String
{[code].....
However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:
var send_lv:LoadVars = new LoadVars();
send_lv.data = JSON.stringify({some json object});
var response_lv:LoadVars = new LoadVars();
response_lv.onData = function(rawdata) {
[code]....
In somepage.php, I can grab that JSON data using $_POST['data'].However, on this project, the developer of the web service requires the JSON content to be the BODY of the request (i.e., not a name/value pair). Is this possible with LoadVars?
I'm new to JSON. This is the .json I want to decode but I always get this error:
[Code]...
I had no problem working with xml in cumbersome AS2, but apparently it's menat to be easier in AS£, however I'm having a problem getting the data from this piece.
Basically I need to be able to access the id & src.
Here's an example of my XML:
</State>
<State name="AR" eVts="6" pCls="8:30 PM EST">
<PrecRepPct>11</PrecRepPct>
[Code]....
I'm wondering if its because there are two "Cand"s, or "Cand.length(); isn't the right thing to use or whatever, I've totally hit the wall.
I am sending a request to a server, and in return I get a long block of JSON.
{
"response":"success",
"assignments":{
"17733":{
"asnid":"17733",
[code]....
Is there a way to do this? I checked if the property was enumerated and it returned true, but I cant find a way to access this data.
I have to work with webservices in Actionscript. I found the following code that allows me to use JSON URLs that implement only the GET method. However, it doesn't work for POST methods (doesn't even enter the "onComplete" method). How can i "POST" JSON data using Actionscript 3.0?
package
{
import flash.display.Sprite;
import flash.net.URLRequest;
[code]....
So, my issue is this: I want to access XML like this:
Code:
someXML..nodeName
This returns elements with the name "nodeName" I need to do this dynamically like
[Code]....
I am unable to access 2nd element and 3rd element (I can access 1st element)
XML :
<data>
<text1> text1 </text1>
<text2> text2 </text2>
<text3> text3 </text3>
</data>

I need to access the elements of an array that is declared in the main swf(_level0). But I need to change it from another swf.How can I do it??So far I have this:
MAIN SWF:
var vector1:Array = [biblio_vid1, biblio_vid2, biblio_vid3, btn_1_4, biblio_vid4];
OTHER SWF:
var vector2:Array = _level0.vector1.slice();
trace(vector2); // undefined,undefined,undefined,undefined,undefined
Is there a way to access the DOM-Elements of a mxml file in a way that you can in JS (e.g. using Prototype or jQuery)?
I need to know if a top-level element has a child (sub-sub-...-childs) with a certain id.
In JS (using prototype) it would be something like:
$('tabs').select('[id="something"]');
Does anyone know if its possible to access children elements in a SWC? I have created some MC's and inside of some of these MC's I have some dynamic textFields. I export the content to a SWC and load it into my Flex project. No problem loading it or accessing the parent elements, they display fine. But I want to access the textfields nestes in the MC's and modify the text. When I debug the app, I can see the textfields as child elements. It's typed as a TextField and the Instance Name is the same as input in the Flash IDE but I cannot access it. When Flex compiles it throws an error saying it doesn't recognize the method. I've tried to insert actionscript on the timeline, linked external classes and nothing can be accessed.

I have an object, myObj, that has no key/value pairs, only elements. When i trace it out i get the elements listed inbetween curly braces {item1, item2, item3, item4} I can access the first element by calling myObj.first( ) and I guess there are other methods I could try to call on the object - such as myObj.last( ) - but I can't seem to access the other elements in the object. I would like to be able to do something like:

If I Have an XML variable that equals this:
var X:XML=XML("<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" xmlns:ns1="Tools.*" minWidth="684" minHeight="484" creationComplete="Init();" xmlns:ns3="Components.*" initialize="I()"/>");
And I try to list the attributes via:
var AList:XMList=X.attributes();
The three namespaces, "xmlns:mx","xmlns:ns1", and "xmlns:ns3" aren't listed among the attributes! How can I access this information programmatically?
Access stage objects (like Movie Clip or text fields) from sub classes.The problem came when I define a subclass and try to access stage objects. How can I do that?Imagine I have a movie clip named redBox_mc on the stage.I want to change it`s alpha after I get my xml loaded.(or any other action in subclass)
Main class:
package src{
// ..
public class code01 extends MovieClip {
public var rt:xmlReader = new xmlReader("art.xml"); // my subclass

how can you access elements in a 3D array using for loops?
View 4 RepliesI'm looking at the XML class. I would like to be able to access elements by name and the order they came in.
For example, if an xml document is structured like this:
<a>
<b>info</b>
<d>something</d>
<b>more info</b>
</a>
[Code]...
xml_object.childNodes.length will return the number of childnodes there are. But I don't see a way to get at the number of childnodes of a particular type. This will not tell me, for example, how many childnodes of type "b" that "a" has. I can't see Flash XML support being this sparse. Is there a built-in way of accessing the nth child of a node of a particular element name or am I stuck with accessing it only by number.
I have an external class in a .as file, my problem is that I can't access text box elements on the stage. Code like stage.txtfield.text or this.parent.txtfield.text does not work. The txtfield is the instace name of a Dynamic Text field.
View 4 RepliesI'm writing a FlashLite ActionScript2 piece of code. I have a series of textfields that are dynamically created and displayed on screen. I then wish to drag each of these textfields around. To achieve this I used some code from another flash site for dragging and dropping. I have two problems:
1) The txtMovies are dynamically allocated so each as a number appended to it, i.e. txtMovie0, txtMovie1 and so on. I can't figure out how to assign these in a non hardcoded fashion within a loop i.e.
object_array[0] = ("txtMovie"+i);
When I do this, it doesn't work. I think it's because it's not an object but a string. I tried using Object as a prefix to the part in brackets, tried [ ] etc... but couldn't get it to work.
2) In the function fnTxtMovieOnRelease I'd like to access the parameters (i.e. .text) of the selected text movie but, I don't know how to access it. I have no idea how to detect which of the movies are selected and thus access their individual text strings. I've tried to pass a parameter to the fnTxtMovieOnPress function but this then stops that code from working and I really don't know why.
[code]Also pass the Stage reference still it not showing any error and text box is also blank,text is embed ed and the code is.[code]If I put import flash. display. List; it shows an error 1172: Definition flash.display:List could not be found.
View 5 RepliesI was wondering if someone could explain or point me in the direction of how to implement an API that uses JSON in ActionScript 3.0. What I specifically want to know is how would I grab specific information. The following is how I do it in XML but I don't know how I would do something similar in JSON as in getting the equivalent of an XML tag. For example with the twitter API I'd like to grab the text [URL]

I would like to be able to access all the components of say a Flash image gallery on someone else's site. I want to be able to find the images, image coordinates, action script code, audio files, video, etc. I do not want to manipulate these elements, I just want to view them and their related information.
View 2 RepliesI have a custom class I am working on, one of the methods is:[code]Inside that function a dynamic TextField is created called txtLoaded, it is declared with [code]mcProg is added to the stage, I see the txtLoaded txt field drawn as well and I can trace properties of mcProg from elsewhere in the class but I cannot access mcProg.txtLoaded from anywhere else in the class.I imagine this must be a scoping issue, with txtLoaded only existing inside the createProgress method, but is there any way for me to be able to access txtLoaded from elsewhere in the class?
