Javascript :: JavaScript Socket Vs Flash Socket?
Apr 30, 2010
Steve Jobs just posted this article on why Apple rejects Flash... [URL] I agree that javascript and css can be used to replicate some of Flash's animation, though Flash does all sorts of scaling and tweening that is incredibly powerful, and I'm not sure that there's anything comparable in javascript, if there is, I certainly haven't seen it.
However, my question is about the socket. Flash has an incredibly powerful openSocket class that allows you to connect to a server and have the server and the client talk back and forth to one another. As far as I know there is no equivalent class in Javascript. Am I mistaken? Is there some secret mystery Ajax class that replicates the openSocket? If not, then that feature alone makes Flash an invaluable tool.

I'm creating a client-server game. My client is a flex based game, and my server is erlang server. At the beginning, when I test directly my flex client in flash player, I can establish a connection easily to my erlang server through socket connection. And both can exchange data with no problem. The problem rise when I deploy my flex app at Apache http server, and running it using a browser by calling [URL] my flex socket sends message requesting for a crossdomain policy to my erlang server. So I create an xml message that represent a crossdomain policy, and send it back to my flex app as a response for that request.
Yet still I can't establish any permanent socket connection between my flex client and my erlang server. I know this because I add listener on my flex socket that will modify its internal state to CONNECTED, if a connection between client-server has established.

I need to execute some javascript string code from flash swf file using actionscript 3.
I read that it could be done by passing the javascript code to the parent html document , using externalinterface.call function. Then I assume it will be faster if I can declare functions in the javascript code in the HTML document in the first use of externalinterface.call funtion ; if flash code calls the javascript code repeatedly. So let me ask you how to do that. For details , any javascript to be loaded is unknown in design time and I can not prepare a javascript file to be loaded.

Is it possible to pass file names from a running Flash application, which only purpose is to enable multiple-file-selection, to a JavaScript application which handles upload of all files to the server?I have examined various Flash upload solutions (like SWFUpload, Uploadify, etc.) and none of them meets my needs. I want an easy to implement solution (like Uploadify) which also lets me specify various parts of the HTTP request.
The reason I need this is because my upload form uses session cookies (for user authentication) and an CSRF token both passed to the server when uploading files.Is it technically possible to pass filenames (+ paths) to a JavaScript application which then handles the upload?

Here's the challenge: I have a Flash movie which will be embedded in a page using an unknown DOM ID that I want to be able to identify/store for callback in a JS function. My ideal user flow would be: User clicks button in Flash. Flash pauses any animations / video / sounds / etc. Flash calls an injected JS function to display a page-covering overlay experience. When user closes overlay experience, a callback method on the Flash object is called. Flash resumes playback.
The problem is, when AS3 uses the ExternalInterface.call("functionName", args...) method, there doesn't seem to be a DOM event triggered, and thus it is impossible to tell which object called a JS function, so having a "registerMe()" function doesn't seem to work. Basically, the injected JS function has no way to determine which DOM object to call, because the ID of the Flash object is unknown.

which is in an .as file which I assume somehow becomes the swf file. How would I go about this and 're-compile' the .as file?

let suppose i have a object named "data" which has a callBack function named "closeItem" which does something. So i have flash file which has a close button. on click of that i am calling this function which closes this item. So issue is? If i pass this "closeItemFunction" as global function this works fine. but if a pass this function as a "data.closeItem" this doesn;t work throwing some falsh error. so i just wanna ask that "does flash only call gobal scoped javascript function" ??

With all the recent hype about JavaScript and HTML5 replacing Flash, I wanted to know - How would it be possible to protect client-side js code? Of course, it is possible to obfuscate it, but that would only make it a little harder. Also, for games which submit high scores to the server, wouldn't it be incredibly easy to modify those scores before they are sent to the server? I know even Flash files can be decompiled, but they can be obfuscated and flash decompilation is not as easy as modifying data in JS - could be done easily using a plugin such as Firebug. I'd like to know everyone's views on this.

I have a flash file that contains a package "game" which has a class "Scores" and a method setValue(). I want to write some lines of Javascript that allow me to call that method. Someone directed me to this tutorial, but I am still a bit confused.
Javascript: alert("start"); var so; so = document.embeds[0];
so.addParam("allowScriptAccess","always"); import flash.external.ExternalInterface;
ExternalInterface.call("setValue[2600]");
displays an alert to tell me that it has indeed began to execute saves the embedded flash file into a variable and sets access imports that class calls the method.I am not sure about how this class thing works? This is just the bits and pieces I was able to come up with from that site, but I don't really understand how it all works (but certainly hope to eventually).This is the site: http:[url]...how-do-i-access-flash-function-using-javascript.When I execute the code with the importation nothing happens, but the alert does come up when I don't have that statement?

I'm wondering if its possible to do what I'm thinking, and if it is possible, does anyone know of a flash object that does what I need? I know a Flash object can provide a javascript API to interact with it, what I dont know is can Flash send an email directly without the need to talk to the webserver to do so? If thats possible would it not be possible to write a flash object that did nothing but provide an API to send emails? Has such a thing been created that is out there for others to use?
I'm looking to create a email form on a web page but the site is static (no server scripting). In my situation server scripting is not possible as there is no server, the site is 100% client side on a CD/DVD/USB Stick.

I have moved on now to where this is clearly a Flash security thing.I have a flash client that attempts to connect to an open socket on the same host as the one on which it lives.I am able to connect successfully from inside the Flash IDE, and when I run the swf movie locally on my machine, after granting it security clearance in the white list it connects as well. However, when I call the movie via the browser (URL...) it fails to connect.The socket reports that a connection attempt is made but immediately disconnects.I have a crossdomain policy file that looks like this: in the root directory of the host.[code]In the flash movie I have a line that looks like this: System. security. loadPolicyFile (URL...);And I'm thinking maybe that's where the problem is, but the documentation on how to use this method is not entirely clear. I'm in Flash CS3

I'm trying to work out some kinks in a multitouch application I've built. It uses flosc to communicate with a xml socket server that sends the multitouch events. This all works fine and dandy for most of the time.
But if I'm mean and flood it with multitouch events Flash can't keep up with parsing the input, and the socket just keeps getting data that piles up until it either catches up or the whole thing crashes.
I have no problem discarding input once there's too much*, but I'm having trouble devising a clever way to do it.
* The app does 6-10 simultaneous inputs with no problem, things start to get hairy once I have to deal with 20+ which basically means someone is lying on the table ;)

I am trying to connect to a socket server from flex. I read, on adobe's documentation, the client automatically sends a "request-policy-file" xml element to the socket before allowing it to be opened, and should receive a policy file.
The client sends the xml element as expected, My server receives it (on the port I want to use, port 6104) and replies on the same port with:

In my Flash app, I'm connecting to my server like this:
Security.loadPolicyFile("xmlsocket://example.com:12860");
socket = new Socket("example.com", 12869);
socket.writeByte(...);
socket.flush();
At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this:
[Code]...
I get no security warnings, which I used to get before the policy server was in place. Still, the connection to port 12869 doesn't work. It's made (I can see with Wireshark and on the server), but no data is sent by Flash. It might be worth knowing that the SWF itself is served from example.com as well.

I am trying to debug a socket connection issue between flash in a web browser and flash in a client type program. The connection is closing properly in the web, so I would like to understand how the web side of things work. Right now I can load up a remote flash file in a web browser and that triggers a connection ESTABLISHED stat when viewing with netstats -fn. When I close the dialog which runs some javascript to remove the flash from the dom, the connection stats goes to TIME_WAIT. Does the act of removing the flash from the html DOM sever the flash connection which triggers a TIME_WAIT state? How does that process work?

I was just doing some testing using PHP sockets and Flash. I used several things, one thing is this tutorial:I have the server running, and when I run the swf via Flash it connects fine. But when I run it from the browser it can't connect.. Because that Tutorial is in AS2, I also wrote a quick client to connect with AS3, but I'm having the exact same problem.. it only connects if I run it through flash.Here's an example of the basic code:
Code:
var s:Socket = new Socket('my IP', 5445);
s.addEventListener(ProgressEvent.SOCKET_DATA, getData);

I am looking for a flash mp3 player that will work within the Opera-based browser on the Wii. The player needs to be javascript enabled (support methods like play, stop etc.) The mp3 tracklist will be built dynamically using ajax on the same page as the player so it must trigger an event when a track finishes playing (or at least provide functionality of some kind to indicate that it's time to start the next track). Does anyone know of such a player?

So, this is a copy of another post I made, but I get a sneaking suspicion I put the post in the wrong forum:[URL]..The summary:
The Socket class in flash player sometimes, for some users (across all sorts of OS and Browsers) will not ask for the policy file from port 843 first, but instead will go straight to the port of the outgoing request, which in this case is our game server, who doesn't really understand the request.
In every case so far the user *is* using the latest version of flash too, so it's not an issue without outdated policy methods, which would have been my first guess.For most people it works just fine, but I posted a log in the thread for one of the non-working players. It's pretty mysterious, and I haven't found a fix yet... though I'm going to experiment with some work arounds.

I'm trying to implement a binary protocol between a flash application and a Custom Java Server using TCP/IP sockets, the protocol's messages are of variable length, so my idea is to add a field indicating the number of bytes I have to read before parsing a complete message, something like this:[code]if while processing a message (supossing it is complete) other data arrives through the socket, are messages of type ProgressEvent.SOCKET_DATA queued so the number of times my handler is called is equal (at least in this case) to the number of messages arrived or should I read until all data the socket has available? or simpler: are in general messages for a handler queued in flash?
