Javascript :: Passing File Paths From Flash To JavaScript For Upload?
Sep 29, 2010
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?

Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):
Uploadify - not many releases, latest 12/2010, no documentation (!)
SWFUpload - latest release 03/2010, documentation
fancyupload - looks buggy.
phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?

I am trying to create a multiple file upload flash application to be called from an External Interface, but it isn't working.
AS3:
var fileRef:FileReferenceList;
ExternalInterface.addCallback('selectFiles', showDialog);
function showDialog()
[Code].....
When I run the script and comment out the fileRef parts and uncomment the alert call, it shows the alert, also when I comment out the ExternalInterface call, leaving only the fileRef parts, it shows the file upload dialog.
When I run it as intended, I get the following error:
Error calling method on NPObject

On a webpage, is it possible to split large files into chunks before the file is uploaded to the server? For example, split a 10MB file into 1MB chunks, and upload one chunk at a time while showing a progress bar?
It sounds like JavaScript doesn't have any file manipulation abilities, but what about Flash and Java applets?
This would need to work in IE6+, Firefox and Chrome. Update: forgot to mention that (a) we are using Grails and (b) this needs to run over https.

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.

I'd like to call a javascript function from an embedded .swf file. Specifically, I'd like to call a function in one of my externally linked javascript files from within: function loadTrack(){
[Code]...
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?

Does anyone know the file upload hack for Flex, which will allow files to be uploaded to authenticated web services via multipart form post? In this bug report from the Adobe site, a user reports: Flash isn't cross-browser compatible if this feature only works via Javascript hacks. So far, I've been unable to craft such a hack. I'm unsure what to do next. Here's what I've tried so far (all have been unsuccessful or impossible).
Set cookies on url
Pass cookies to Flex URLRequest
Create hidden html form in javascript to post file

Basically I'll be working with large XML files (approx. 20 - 50 MB). These files needs to be uploaded on a server.I know it isn't possible to touch the files with javascript, nor to implement HTTP compression on the client-side.
My question is that if any solution exists (flash / action script) that compresses a file and has a javascript API? The scenario is this:
Trying to upload 50 MB XML file Before upload a grab it with Javascript and send it to the compressor.Upload the compressed file instead of the original one.

I'm looking for multiple file upload component with alternative ways.I need HTML5, Flash and normal upload support, depended by device.I don't like FancyUpload, because it uses mootools and mootools is very big library.Also I can't use jQuery, because I'm writing on Ext js and it's not good idea to use two big library like jQuery and Ext js.

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 have an upload form for an image. The user clicks browse and selects a file. How can I get the image dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this? This is the code I'm using to tie into zozo's getImgSize() function, but it gives me 0*0 as size.

My goal is to pass a variable from JavaScript to ActionScript in my swf file. I am using Flash CS3 and AS3. Currently all I want is my test to work where I mouseover a text link and a function is called with a passed variable in my swf file.
Here is my code:
// test.html - Cropped out the excess code
<html><head>
<script type="text/javascript">
function myMovie(movieName) {
[Code] .....
ExternalInterface.addCallback("sendToActionScript",fromJS); only once, or inside of my function onEnterFrame(event:Event) loop? I tried both, but since I can't get it to work I don't know which one is the proper one.

I'm looking for a flash widget that allows users to record their audio and then send it to the server.
There are a few similar questions:
Record Audio and Upload as Wav or MP3 to server
They advocate using Red5 or flash media server.
Shouldn't it be possible to record locally on the user's client using the codecs that the user already has and then upload the resulting file to the server, rather than say, process the and record the stream on the server itself.

Is there a way that I can pass the value of app: or appstorage: to a javascript file which has been included via URLRequest? I have a web application with an HTML5 video player, and I've been asked to get it to work as an AIR app. So far so good, except that there is a bug in jPlayer that requires you to use absolute file paths for media if you're using flash fallback. I need to get the file path of the app: or appstorage: directory on a users machine, and pass that to javascript so that the player can find my videos.

I have a simple standalone application written in Visual Basic that I'm porting to a browser based application using PHP/javascript. The original VB application has some simple embedded flash games with token and point counters. The token and point values are being passed as variables between the application and the game.
I'm trying to achieve the same effect in my PHP port without modifying the actionscript code( using the variables in actionscript that already exist). Below is Visual Basic code that's loading a value from a database and posting that value to flash using FlashVars:

Passing a JavaScript array to Flash?I want to pass an Array from JavaScript to a Flash movie. My goal is to create an Array of URLs to pass to Flash and once the Array is in Flash, I can access those URLs in the movie.I know how to send a variable to Flash using the "Embed" and "Object" tags using "FlashVars".
<PARAM name=FlashVars VALUE="song=song_URL">
but I want to somehow send and array, or maybe can I call a function that creates the Array I want to send?My reason is to have an HTML developer come back and change the Array values and that will change the Flash Array, so they don't have to edit the Flash movie.

A brief overview:
1. I am working on a project in ASP and I am making queries to a SQL db that returns data back in the form of xml. I am not in control of the db or how it returns data.
2. I process the XML within the ASP page and then I also process the data from within flash. I am therefore making two database calls for one page view.
3. I am trying to figure out if I can in anyway, pass an XML list from the page to flash so that I am making only one database call. The site is heavily hit and I am practically doubling the server load. Basically, the only way I think that may be possible is through javascript but not sure where to begin.

We can pass arguments to flash from javascript like this
fc.callFunction("_root","js_playSong",["Path=songs/song1.mp3 &Album=Jazz"])
where fc is a JSFCommunicator.
But how to pass argument like this
fc.callFunction("_root","js_playSong",["Path=songs/song1.mp3&ArtistPath=http://sample.php?artist_id=24&name=kamal"])
In the above argument the red colored ampersand should not be considered as separator between two variables.

Is there an existing javascript library for relaying key press events in the browser (or certain divs) into flash? I am hoping there might be a library kind of like this one for mousewheel events?Something like this handles javascript keyboard shortcuts great. I suppose I could just listen for those events and pass the ones I want into flash?These are great examples, however, if flash has focus, then javascript keystrokes are lost. How can you ensure that all key events go through javascript?

I'm able to record sound with a Flash application embedded in my website, this audio is saved to a ByteArray, which I need to pass to Javascript in order to post to my server along with other required data.
I know I can use AS3 ExternalInterface class to communicate with Flash from Javascript, but what would be the appropriate format or variable type in javascript to hold the ByteArray, and how can I ensure that I won't lose much audio data when doing so?

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.

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.
