I am attempting to parse some JSON from a URL via Flash/AS3. Here's my code so far:
> import com.adobe.serialization.json.JSON;
> import com.adobe.serialization.json.JSONDecoder;
>
> var loader:URLLoader = new URLLoader();
[code]...
The trace(loader.data.toString() + "
") outputs a bunch of HTML.
What I want to do is make a get request to this URL: [url]... which should return some JSON and then parse out certain information from it.
How would I go about doing this in Actionscript 3? I'm more concerned with figuring out how to get the data to feed to a JSON parser rather than parsing the JSON, since there seem to be plenty of questions about parsing JSON. The reason I want to do this in AS3 is that I have a 3D flash visualization set up and I want to get this data, parse out the relevant bits, and then display the parsed bits in the visualization.
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 have dates in JSON which are generated from ASP.NET pages using the JSON.NET library. [code]...
How do I parse these with ActionScript from Flex 3 Professional? I'd like to have this in a native data format.
I am running flash cs5.5 and attempting to use the JSON calls that are in flash player 11. I patched my install so that I could select flash 11 as the target. When I run in a browser, everything is fine. When I publish to a macos projector, the JSON pieces do not work.
Is there any way to make it work?
Here is my code:
private static function on_complete(e : Event):void
{
trace ("Http on_complete!");
[Code]....
This works as expected in the browser, however in the projector it never gets beyond the ob=JSON.parse call. I can tell where it gets by uncommenting the amount=xxx lines
I cant tell what it is doing because as far as I know the debugger in cs5.5 is flash 10, so it doesnt work for debugging. I am wondering if whatever it uses to cram into a projector file is running flash player 10 as well?
I am trying to return results from my SQL database, using PHP to convert it into JSON, which is then read by Flex. Here is the parse error I receive -

I need to parse a large trace file (up to 200-300 MB) in a Flex application. I started using JSON instead of XML hoping to avoid these problems, but it did not help much. When the file is bigger than 50MB, JSON decoder can't handle it (I am using the as3corelib).
Try to split the file: I would really like to avoid this; I don't want to change the current format of the trace files and, in addition, it would be very uncomfortable to handle.Use a database: I was thinking of writing the trace into a SQLite database and then reading from there, but that would force me to modify the program that creates the trace file.
I am using JSON to parse HTML data with customized html tags in Flex. Flex's support for HTML is pretty minimal, so I am wondering if it's possible to do a simple font color change rollover effect on these links. Currently I have found that Flex only supports a few HTML tags, but also supports CSS through Flex's whack CSS methods. Can I manipulate HTML that is written in my JSON files through an external CSS file? Or better still using a simple tag with the JSON file?

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 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.

I have a 3rd party programme which generates the xml file below, and it re-writes the xml file every time a new message is received by that 3rd party programme. What I'm trying to do is find a way to read in the relevant flashvars (if that's the right term) into a flash file (basically I want to read in messages 1 - 6), ignore the rest of the xml, display the messages and then re-load the xml about every 30 seconds (in case it's changed). I guess this is pretty much like a news reader of sorts, but I don't have any control over the structure of the xml file, so if someone could point me in the right sort of direction, then I'm happy to have a go at learning. I did try messing with a basic news reader flash file that I downloaded, but it didn't seem to like the xml - I guess because each message in the xml has its own number?[code]...
View 2 RepliesWhat is the best way to pass JSON to and from a Flash movie?Currently to communicate between javascript and Flash :I'm using 'flashvars' to pass data to the flash movie when it initially loads I'm using 'ExternalInterface' at runtime to transfer single values, such as booleans at runtime I want to move to the next level and do this with JSON now.
Initially I just want the ability to send JSON to the flash movie on instantiation, but later i will need to send data back and forth.I just want to do it right first time and avoid any compatibility or 'gotcha' issues if there are any. i dont even know if i can pass a whole object to Flash, or if i need to serialize it as a raw JSON string.
I've flash app and i've static data (like ~18.0KB) for it which aren't changed often so I was wondering how to better get them. The static data may be in XML or JSON. One of my ideas was to put the static data in .js file within a function which would return them in JSON list and the other one was to return them in XML (as I like to work with XML more in Flash) somehow. But I'm not sure if it possible to put XML stuff in JS file to return them when function is called.. Or is XML pages also cached in browser and I will get the same performance result which I would get with cached JS files?
View 1 RepliesTo read JSON using as3, are there any built in methods? It would be better if we get some code samples.
View 1 RepliesI know most people hate 100% flash-based websites, but I was recently forced to use flash for a college assignment. After creating a fully-featured ria in less than 2 weeks with every feature I could imagine, i've regrettably fallen in love with this beast (which I previously refused to touch with a stick) due to the power of AS3 and the ability to sprinkle it everywhere :-
I now want to port a commercial desktop application of mine (which has been largely unsuccesful) to the web and feel flash/flex is an excellent candidate. While creating a html/css/js version would be ideal (working browser shortcuts, for a start), i'm certain it'll take a year to create in cross-browser html/css/js what would take just ~3 months in flash. Obviously as the (paid) desktop product was unsuccessful, i'd want to minimize the risk/investment in the (free) web application.
I plan on using JSON for web services, so it shouldn't be a huge pita to port in the future.Is this a good strategy for launching a web app you're not yet 100% committed to? Or will the fact i'm using flash doom me from the start? Has anybody else done this? If so, how did your userbase respond to the 100% usage of flash, and did you get around to porting it to standard web technologies?
I have read a lot about parsing JSON with Actionscript. Originally it was said to use this library. [URL] but it seems Flash Player 11 has native support for it now. My problem is that I cannot find examples or help that takes you from beginning to end of the process. Everything I have read seems to start in the middle. I have no real experience with JSON so this is a problem. I don't even know how to point ActionScript to the JSON file it needs to read.
I have a project with a tight deadline that requires me to read twitter through JSON. I need to get the three most recent tweets, along with the user who posted it, their twitter name and the time those tweets were posted.
The back end to this is already set up I believe by the development team here, therefor my JSON files or XML just needs to be pointed to and then I need to display the values in the interface text boxes I have already designed and created.
