ActionScript 3.0 :: Cannot Load Swf Using ExternalInterface.addCallback
Jun 29, 2011
I try to create a switcher-swf. Its purpose is to detect parameters like screensize and then decide whether to load lowres.swf or highres.swf. Both lowres.swf and highres.swf work when tested independently.
The problem is the switching doesn't work. It's not the loading- or switching procedure itself. Rather I tracked the problem down to this single line which is present in the classcode of both lowres.swf and highres.swf:
PHP Code:
ExternalInterface.addCallback("update", update);
All it does is make a function called "update" available for external javascript-calls. If this line is removed, everything else works (including "ExternalInterface.call()"-statements!). However, I absolutely need this update-function to be available.
It seems that loading fails when the swf to be loaded contains an ExternalInterface.addCallback-Statement.

I have been trying to get this working for a while now and am at the end of any ideas or samples.In 2.0 it was setVariables and was not problem.But now I'm trying to get ExternalInterface.addCallback to work and just can't seem to get it to work.Just want to send a variable from javascript to actionscript class.Ok, here is the javascript:
Code:
function thisMovie(movieName) {
if (navigator.appName.indexOf("Microsoft") != -1) {
return window[movieName];[code]....
I have been trying to get this to work but with no luck.It's in a .Net aspx page. Even stripped the page of everything but this with no luck. And no master page either or ajax.

This is so frustrating...I'm going to do my best to be concise here, so forgive me if I leave too much out.I'm also going to try to simplify so I don't get bogged in details. I have a set of html pages that guide you through a tutorial. The different pages are REALLY just one big page that has divs hide and unhide as you go through the flow via previous and next buttons.
There are 4 pages which play a video clip. Each video clip .swf contains an FLVPlayback component that plays an .flv, and uses an .swf skin file. All these things play fine. If you're watching a video and you click "NEXT" the sound is still playing because of course you're still on the same page. So we looked into it and found out about the whole ExternalInterface.addCallback thing.

It's not working. What am I doing wrong?

I've got this piece of code in flash:

This code works perfectly with Chrome, Firefox and Opera but won't do it in IE. And... I also would need to have it working on IE6 = PS: the alert works fine in all the browsers (except IE6,7,8 because of the .src attribute =_=)! So I think the problem isn't the object retriving.

I have never posted to this forum before but I am about to pull my hair outI've created a page that used External Interface before with no problems and I can't figure out what makes this one different. It works fine on both Firefox and Safari on a Mac. On a pc, however, the Flash has no problem calling JavaScript functions but the JavaScript can't call the ActionScript function. It doesn't matter if I try Firefox, IE7 or IE6. The error IE gives is that the object doesn't support the property or method.ere is the AS:
Code:
this.createEmptyMovieClip("samplework_mc", 999);
function loadWork(workname:String):Void {

I'm trying to call a method inside a flash movie from js, every time the mouse leaves the "div". It works on Internet Explorer, but not in firefox. Here is the html script:
<script type="text/javascript">
window.onload = function(e){
init();
}function init(){
document.getElementById('div').onmouseout = function(e) {
[Code] .....
Here is example of the problem, there is an alert for the js and the flash should be able to remove the swf (see a gray background? it works! see a image, flash didn't receive the call): [URL]. This should work with internet explorer / safari / chrome (pc/mac) only firefox seams to reject this.

Let's say we have a number of ExternalInterface.addCallback functions, like so:
ExternalInterface.addCallback( 'foo', handler );
ExternalInterface.addCallback( 'bar', handler );
ExternalInterface.addCallback( 'foobar', handler );
In the function handler I'd like to find the method name called through the external interface, such as foo, bar or foobar; is there a way? Eg:
private function handler(...args):void
{
arguments.callee.arguments[ 0 ];
}

I'm trying to call a function in an action script using the ExternalInterface.addCallback API, but I can't seem to get it to work. Here's what I have:
ActionScript:
//MyClass.as
package {
import flash.display.Sprite;[code]....
The Error I'm getting is: Uncaught TypeError: Object #<HTMLObjectElement> has no method 'getStringJS'
I also tried adding in a timeout in case the swf file wasn't loading, but I didn't have any success with that method either.

I'm working on a Flash game that needs to call some Javascript on the page and get data back from it. Calling Javascript from Flash works. Calling the Flash functions from Javascript (often) doesn't. I'm using the Gaia framework.The swf is loaded in with SWFObjectThere's a button in the Flash file. On click, it uses ExternalInterface.call() to call a Javascript function. This works.The Javascript function calls a Flash function that was exposed with ExternalInterface.addCallback().Sometimes, the Javascript produces the following error: TypeError: myFlash.testCallback is not a function.
When the error happens, it affects all functions registered with addCallback(). Gaia and some of its included libraries use addCallback(), and calling those functions from Javascript also produces the TypeError.Waiting a long time before pressing the button in Flash doesn't solve the error.Having Flash re-try addCallback() periodically doesn't solve the errorWhen the error occurs, ExternalInterface.available = true and ExternalInterface.objectID contains the correct name for the Flash embed object.When the error occurs, document.getElementById('myflashcontent') correctly returns the Flash embed object.Edited to add:This issue shows up in Firefox 3.6, but not Chrome or IE8. I haven't tried older browsers.
I'm running the Debug version of the Flash player.My calls toExternalInterface.addCallback() are wrapped in a try...catch block. When the JS error occurs, the catch block is not triggered. It's a silent failure.The error occurs when testing on a webhost, with the swf loaded from the same server as the page it's on.
I set allowScriptAccess = always.Setting flash.system.Security.allowDomain("mydomain") doesn't fix the error.From my Page class:
public class MyPage extends AbstractPage
{
// declarations of stage instances and class variables

Mainly because I have it ALWAYS working locally, when I test in a browser, but the moment I deploy to a server it stops working.
I've added trace commands and confirmed that ExternalInterface is in fact available before adding the callback, and an alert command in the javascript method correctly identifies the flash object. I also checked and allowscriptaccess is set to 'always'.
Could it have something to do with the flash being served on a remote server?

In my Flex app, I need a Javascript control to call one of my Actionscript methods. Simple enough, according to the Flex/Actionscript documentation, I wrote this in my Actionscript code:
if (ExternalInterface.available)
ExternalInterface.addCallback("setName", setNameInActiveWindow);
In the Javascript control I wrote:
document.getElementById('FlexAppId').setName(name);
Works great. Exactly as expected, so I went to production. But it doesn't work in production :(. Same exact code... I can't figure it out. The above Javascript code is run, but the callback is not executed in the Actionscript code.

I thought this question would answer my question, but I have applied the following fixes:
.as
Security.allowDomain("*");
Security.allowInsecureDomain("*");
html
param name="allowScriptAccess" value="always" />

And I am still seeing the ExternalInterface.addCallback method fail locally. It works on a web server, or in the dev folder. But not in an arbitrary local folder.

I am trying to write C++ code to interface to arbitrary instances of flash player 10 contained in arbitrary web pages from IE. All I need to be able to do is:
1) determine if the player is playing,
2) start playback, and
3) stop playback.
I am searching for a way to so this programmatically, without resorting to simulating user input to the control.
I have played around with the IShockwaveFlash COM interface which works OK on some sites but not others (e.g. not on YouTube). I am wondering if it is possible to use IShockwaveFlash::CallFunction() with the appropriate XML string to invoke predefined functions in ActionScript that have not been explicitly exported using ExternalInterface.addCallback().
Or perhaps there is enough functionaly using accessibility and the IAccessible interface?

I have been trying everything I can find to have code start on the window.onload event that uses callbacks exposed via the ExternalInterface. I've had many of the attempts working in IE, but Firefox is causing me grief.I tried simply calling the code via an "onload=" statement in the body tag for starters, but that didn't work because (I'm assuming) the Flash piece wasn't loaded when onload was called. So I tried putting a line in the Flash that calls a javascript function once it's loaded up. I tried this both by putting the ExternalInterface.call statement in a "this.onLoad=function(){" block as well as just putting the call at the end of the statements on frame 1 of my presentation (with a stop() on the frame) - either way it isn't happening in Firefox.I also tried using a setInterval in Javascript to test to see if one of the methods exposed via the ExternalInterface is an object (or not undefined). Once again, it's working in IE, but not in Firefox.[code]
The only other thing I can think of at the moment is using the swfObject for writing the flash tags to the page, but I'm already writing them from an external file (and removing the IE "Click to activate this control" issue in the process). All these methods work fine after the initial load (although I also had issues with Firefox when I simply try to call the onload instructions after a setTimeout command as well).

I've spent about a day on this... Publishing a swf for AS3/FP9, following the example in the ActionScript 3 documentation to get two-way communication between a SWF and javascript. Works great in IE.
I've sifted through what seems like a million posts on the subject, with people getting the same result... the function I/they are attempting to call doesn't exist.
In the documentation example, there's a function to find/return either the SWF as an object or embed tag depending on which browser you're viewing the page in.

I just had this conversation with a colleague and I am now turning to the SO community to provide evidence based on fact, not opinion, as to which tool would be ideal to grow into in the current programming environment. Director or Flash?I am deciding if I should stick with Flash or bother learning Director 11.5. He want to know if he should stick with Director or learn Flash. No, we don't work together. Hehe..
EDIT:
I've gotten ExternalInterface to work with VB.NET, hence the need for Director in the context of its ability to do File System IO and "non-flv" video are eliminated. No if only VB could do the kinds of animation that Flash could do, I could turn towards being a "real" programmer...

I have a flash menu that needs to play a different scene depending on which page it is embedded into. So I need the it to grab the URL of the html page it is on and do some simple test on it to figure out what scene it should be on. *For the record, I tried to do it without scenes but the frame jumping started doing some cracked out things
Code: (on a single empty frame in Scene 1) import flash.external.ExternalInterface; var urlPath; urlPath = ExternalInterface.call("window.location.href.toStr ing()"); getURL("javascript:alert('"+urlPath+"');"); if (urlPath == "http://www.awesome.com/Portfolio/portfolio.html"){ gotoAndPlay("Scene 3", "portfoliopage"); } else if (urlPath ==
[code]....
Somehow, my urlPath isn't getting the correct value, and therefore the if-else latter isn't functioning appropriately. I am posting the website on my test server, so the http addresses are correct, and the if-else latter functions perfectly when I just change the conditions to 'true'/'false', so neither is the problem. The problem is that the alert shows me that the value of urlPath is undefined, and so then all conditions in the latter evaluate to false.
