Flex :: Take A Javascript Library And Run It In Flash?
Nov 23, 2010
Lets say I pick up a pure Javascript library... one that doesn't rely on the DOM in any way.Now, lets say I want to take that library and us it in Flex. Is there any good way to do this? I can't simply include the Javascript, as it is not close enough to ActionScript to compile... but is there a good converter that will do it for me? Take the Javascript prototype style classes and convert it to ActionScript classes?
Lastly, I don't want to use the Browser for this.I know that I can always use ExternalInterface to access the browser, but I am not always running my Flex app in the browser... sometimes it is Air, and sometimes it is in a PDF.

I'm involved in writing a Flex/ActionScript library and in the future I will be involved in writing the same library in JavaScript. Rather than writing a library in each language and having to maintain them separately I was wondering if it was possible to:
1) Write the code in one language and share the code into the other e.g. Write the code in JavaScript and use the same .js files in ActionScript
2) Write the code in one language and perform a conversion into the other
I know it's possible to communicate between Flash/ActionScript and JavaScript but I'd like to avoid the overheads in using the technology bridge so this isn't really an option.
How do other people deal with writing and maintaining libraries that do exactly the same thing but in different languages? Specifically how do people do this between JavaScript and ActionScript?

This isn't another one of those "How can I record audio in the browser?" questions... I know that the HTML5 Stream API is around the corner and Flash can already access the user's microphone and camera. I'm simply wondering, as a Javascript developer with little knowledge of Flash, if anyone has developed a JS library that hooks into Flash's device capabilities for recording but sends the results back to javascript (presumably using ExternalInterface).
In other words... libraries like SoundManager2 utilize a Flash fallback for audio playback, but they don't seem to allow for recording. Has anyone written a JS library that uses an invisible Flash movie to allow audio recording?

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 writing a library in ActionScript 3 which needs to call functions in JavaScript. Since it's a library, there is no AIR, and thus HTMLLoader can't load an HTML containing the JavaScript.
how to call JavaScript which is not in an HTML window?

We have the WebApplication portal. We are generating the stats survey, which needs to displayed on graph. We have started using HighCharts. As a requirement analysis, I would like to know, what are the other alternative for Charting and Graphing. Can you advise/discuss, which is more efficient,effective way of charting? What are the pros and cons for each platform? Any more other alternatives ?

Currently I'm searching for a free solution to simple edit some photos at the users browser. Resizing and Cropping would be mandatory. I'm not searching for an online service (for example SUMO or PIXLR which are great), because I want to include the software into a WYSIWYG Editor. JavaScript would be really nice, but it would have to work in IE 8. Pixastic is a great example, but works only in modern browsers (not IE 8 :-/) Maybe setting up some kind of image processing service with ImageMagick and communicating with it through AJAX could also be an solution? Has anyone gained some experience with such a solution?

I'm writing an Adobe AIR app using plain HTML which needs to upload photos to Facebook. I don't think Facebook's JavaScript/Connect library includes photo uploading functionality, but their ActionScript library does. However, I'm having trouble loading the ActionScript library into the HTML page.
Adobe's documentation describes the process of loading ActionScript libraries into HTML AIR apps, which I tried using the compiled Flash library available here (specifically, Facebook_library_with_AIRConnect_v3.4_flash.swc). So my page looks something like:
<html>
<head>
<title>Hello World</title>
[code]....
Is the compiled library file I used the wrong one (do I need a .swf instead of a .swc)?If so, do I need to create my own compiled library somehow from the ActionScript source?Is the namespace I'm using incorrect? (in addition to com.facebook.Facebook() I tried .Facebook(), .fb.Facebook(), .facebook.Facebook(), etc)Should I just give up and try to learn Flex instead?

I did some work that used Flex datagrids previously. It was smooth for the users and developers alike.
In my current project, I have to implement the same grids but not using Flex / Flash.
I have taken a look at extJS and YUI but they don't seem to measure up.
Are there other packages I should be looking at ?

for some reason, whenever I dynamically load a swf on a $(document).ready() by writing to a div, I am unable to make javascript calls to the browser. Specifically, all calls to the browser return "null". This does not occur when embedding the swf normally on the page load, but I would like to prevent loading of the swf until a specified point in time.
What the heck is going on here? Is there something special about dynamically embedding a swf that prevents the swf from talking to the browser? The methods ARE called (I've proven such by showing alerts), but all return values to any function, regardless of type returned, shows as null when it gets to flash.

We're currently building a Flex application using the PureMVC framework with a shell.swf which loads/unloads modules dynamically. We're experiencing issues with memory and we're looking to replace the shell.swf with a JavaScript-based loader.Two questions:What would be a good framework to dynamically load the Flex components and allow the modules to communicate between each other?Would dynamically loading/unloading the modules via JavaScript take care of the typical memory problems associated with Flex/Flash applications?

I am embedding a flash file in my flex file and then trying to add it to the stage. IU try addChild to a canvas element and to a container element, but it keeps giving me the error, the symbol "myBtn" is cannot be converted to a IUIcomponent.
I understand that I need to place everything inside some sort of component, but what is the proper way to do this in flex?

I have found a way! It's very complicated though... Hopefully someone has an idea on how to clean this up...
The workflow:
------------------
I'm using Flash to draw movieClips which are exported as one assets.swc file and then used in Flex for coding.
The scenario:
------------------
I've been working / thinking about this for the past 3 days.. it's driving me a little crazy. I've simplified my code down to 3 boxes that are drawn onto the screen. Each containing one background movieClip. The three boxes are three individual box clips in the Flash IDE library (different designs). But all three boxes share the same functionality.
The problem:
------------------
When using a custom baseclass (AbstractBox.as) to define all the functionality for the boxes, Flex looses all the code hinting for the movieClips inside the box movieClip (bg in our example) Also it seems like Interfacing doesn't work since as3 can't define MovieClip instances or any other variables in interfaces.
[code]...
Now my question: Why is this so complicated!? Isn't there a cleaner / simpler way to write this?

I would like to do something like this URl...but have the individual lines animate and show progress along a route. It needs to be a 'real' map so that I can feed in LAT/Longs for for the polylines. This is also a similar effect URL... but I don't need the map panning.I am aware of the google maps api for Flash but there doesn't seem to be any animation other than panning.

I've been trying to setup a working method for unit testing flex libraries using Flex Builder. i have tried setting up a standard flex lib project and using Ant to compile and run the units tests. But this means that when something does go wrong and I want to use the flex builder debugger I cannot do so.
So my next plan is to setup the library as a normal as3/flax/air app as I can use the concept of a main class to run the unit tests. I can then compile the actual library code using Ant.
I could also setup a separate companion project who's sole task is to run units tests on the lib. But this is a little awkward as each library now requires two projects to manage. How do other people develop flex libraries and use unit tests to test/develop/debug the code?

I have the job of recreating a flex app in HTML and CSS. The existing app makes considerable use of TextFlow to layout content. For several reasons I need to be quite accurate (within a few pixels) with positioning.
[Code]...
Ideally I'm looking for a library I can use to translate these many attributes into "proper" html and css. The current technology stack is PHP at the back end and javascript at the front end, but there would be little problem in using any other language to do the translation.
Failing that I guess I'll try and write my own, using the api reference as a guide.

Is there a way (in javascript) to detect if an embedded .swf was created with Flash Professional or Flex.We have a page with several tabs, each of which can contain an .swf.All tabs are defined within the same HTML file and the javascript framework calls a .rewind() and .play() on the swf when the containing tab becomes active.This works great on regular flash animation, making sure they start playing from the beginning when the tab is opened. On an swf created with Flex however, the rewind and play wreak havoc on the Flex framework and the application doesn't load.
The best way we've come up with to detect Flex is to count the number of frames the .swf has. With flex that's always 2. But this doesn't sound like the best way.We've also tried to add a callback method with ExternalInterface on the Flex application preinitialize event.Unfortunately this event is called quite late in the application startup and the javasctipt code checks the callback before the Flex code has added it.

I have a colleague who will be using Adobe Flex and adobe flash builder to design the application. The final application will be in that software. I am creating the database features and testing them using online browsers.What I want to know is that some alerts I am getting a 'prevent this message from multiple dialogues' message on the alert but this is because of the browsers. But if the application is on flex and flash builder (I don't know which one is where the app is stored coz I have never used it) then will that message appear on some alerts in that software or is it only on browsers?[code]

I'm building a video player using Flash CS4 (hereby referred to as "Flash") to create the graphic symbols and compiling and debugging with Flash Builder 4 ("FB4"). Here are the steps I take in my current workflow: --Create the graphic symbols in Flash. I've created a few different symbols for the player, but I'll focus on just the play/pause button ("ppbutton") here. --In the Library panel, I go to the ppbutton symbol's Linkage properties and link to a class named assets.PlayPauseButtonAsset that extends MovieClip. I do not actually have an assets package nor do I have a class file for PlayPauseButtonAsset as Flash will create them for me when I publish.
--In Flash's Publish settings, I set the project to export a SWC that will be used in FB4, called VideoPlayerAssets.swc. --After the SWC is created, I create my FB4 project called "VideoPlayer" and add the SWC to my path. FB4 creates the class VideoPlayer in the default package automatically. --In VideoPlayer.as, I import assets.*, which imports all of the symbol classes I created in Flash and are available via VideoPlayerAssets.swc. I can now instantiate the ppbutton and add to the stage, like this:

I have a flex app and I am adding a callback method like this:
private function init():void
{
ExternalInterface.addCallback( "playVideo", playVideo );
}
[code].....
However if I uncomment and run the alert first. I get no error and it works perfectly.My first thought was that the alert was buying time until the script could execute, so i tried to run the script inside a setTimeout() but did not work.
