Flash :: Javascript :: ExternalInterface Works With Embed Tag But Not With Object Tag
Sep 19, 2011
The "modern" updated way to embed a flash object, according to Adobe:
[Code]...
Then it works on Firefox and Chrome (the AS function is called and works properly) - (it doesn't work in IE though). How come it doesn't work with an object tag? How "safe" it is to use the embed tag instead of the object tag? Is it not obsolete? Note, that it is definitely not a timing issue - If I call the AS function from JS from an onclick function - then the results are the same.

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?

I know there have been other questions on getting JavaScript / Flex ExternalInterface to play nicely, but I've what I think is a weird one. It works perfectly in every browser except Safari (on a Mac). Chrome, IE, Firefox - all ok, but Safari, nope it just wont fire.I've copied my code below, can anyone see why it doesn't work in Safari pls ?(the 'are you sure' dialog window appears in Safari but the method in the Flex app just doesn't get called)
Flex code :
if(ExternalInterface.available){
ExternalInterface.addCallback("flexShutdownHandler",flexShutdownHandler);

I have a flash object on my page and I want to disable clicks on it using Javascript. I tried to use the following code:
document.getElementById('flash-obj').onclick = function(){return false;};
document.getElementById('flash-obj').onmouseup = function(){return false;};
document.getElementById('flash-obj').onmousedown = function(){return false;};
It doesn't work. Is there any other alternative?

I would want to catch click with javascript on a embed flash object on my page. I used wmode="opaque" (tried transparent too) and put a low z-index. I tried catching click on a div, on the object element and on the embed element. On FF (5), all three of them work. On IE (7 & 8), none of them work. Here's my code (I removed some attribute for flash like type or classid) :

the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
'null' is null or not an object
try { document.getElementById("").SetReturnValue(__flash__toXML(function() { return document.location.hostname; }()) ); } catch (e) { document.getElementById("").SetReturnValue("<undefined/>"); }
but this is from flash script and i dont have control over it. it just say JScript - script block.

I'm trying to call a function declared with ExternalInterface in a Flash swf, using JavaScript.It worked once, but all of a sudden, it stopped working.I have a debug version of the Flash Player, but no errors occur in Flash.Not even a "Security Sandbox Error" or something. The only error I get is the following error in JavaScript Error: Error in Actionscript. Use a try/catch block to find error.I'm using AS3, exporting for Flash Player 10 and testing on Firefox 3/Safari 4, on a Mac.

i'm currently trying to call a javascript function and pass values to it. but i'm not really familiar in using the addcallback since i only tested on calling a function from flash without passing anything to the function.
Basically, i'm going to retrieve the values of a node from xml. and then i will assign those values to a variable in flash. now what i'm going to do next is pass this value to a javascript parameter..is it done using externalinterface?
I just need to throw the value to the javascript function parameter and no return values to the actionscript. The event is that whenever an image is click, the corresponding value for each image is passed to the javascript function.

Im trying to use JS to send data to my Flash AS2.0 music player with ExternalInterface, except there are no good tutorials or guides on ExternalInterface that I can find. I want to be able to change the current song in the player by clicking a JavaScript link, and on page / window load without clicking, play a default song.
I dont need a super complicated answer on loading sounds in flash, etc., I am just having a lot of difficulties getting JS to send anything to Flash, and when I get that to work - would I need to put some if / else into the flash to determine if the link has been clicked or not?

I can't call a javascript function from flash, when the flash object is added within an OOP structure in javascript. In short the code:
In flash:

ExternalInterface.call("flashMessages", "ready");

Flash gets loaded, but the call to the javascript function isn't received.

I have avoided adobe products like the plague from when I was developing myself since it costs a fortune to buy and of their products, but big employers love it and pay for it so here I am. Our "Flash" guy just left the team and I inherited this issue. If you read my other post you know what is going on so I will move on. I want to make a simple call from actionscript to my javascript taht is referenced in my other post. I specifically want to call the CheckboxCollection function from inside of actionscript. I don't need to pass it any args or anything of the such from inside of actionscript.
All I need it to do is run that function once the flash is done loading. The javascript function will take care of everything I need, I just HAVE TO HAVE IT called from actionscript to make everything work in harmony. I am in the middle of teaching myself all things adobe and actionscript(much to my dismay), but I really have no clue where top go from here to make this work. I have reviewed adobe documentation, but until I have a better grasp of the language as a whole I am still lost. I copied most of my actionscript on to here, but I did leave out everything that had to deal with mouseover events, since my issue is not about a mouseover and they all work like a charm.
UPDATE: I had to stop working on this to get some other things done, but I am back to step one. NO matter what I do I am having no luck making this work. I have tried all suggestions on here, and tried everything I KNOW how to do, but I am having no luck. If anyone could take a look at this post and the one that I link to (It is the companion javascript for this) and see if they can come up with anything. I have tried so many different iterations of my code there is no use putting all of my trials up for example of what doesn't work,
/*
JavaScript External Calls
*/
function RegisterExternalCalls():void
{

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

I'm using Javascript to call a method on a Flash movie embedded in an ASPX page using SWFObject. It works fine in Firefox, but Internet Explorer 7 and 8 (so far) claim the object returned by swfobject.getObjectById() "doesn't support this property or method". I've found similar posts on this site and others, but nothing I've tried has fixed this in IE.
ActionScript 3.0 class:
public class Player extends MovieClip {
public function Player() {
Security.allowDomain("http://localhost");
ExternalInterface.addCallback("test", test);
[Code] .....
Internet Explorer complains about the last line in that function, "Object doesn't support this property or method".

i have some actionscript that makes a
ExternalInterface.call('someFunction');
call.is it possible to reference the html object that made the call to someFunction directly using the ExternalInterface.call call?
Assume that the object that makes the call also has some Callbacks (via ExternalInterface.addCallback) that are accessible via javascript.
Currently:
Actionscript source
ExternalInterface.call("someFunction");
ExternalInterface.addCallback("someCallback",someASfunction);

I'm trying to create an overlay containing a flash player that is shown when a user clicks on a link. The div containing the player starts with display:none in CSS. Upon clicking, the div will be shown, and JS will use ExternalInterface to configure and start the player. The JS configures the player when it catches a "flash ready" event, which is fired by Flash on ADDED_TO_STAGE.All this works, except that the ExternalInterface callbacks are never created. The JS and AS3 work fine if the player is shown upon page load, or is hidden with visibility:hidden instead of display:none. I am aware that Flash will not be initialized with display:none, and this works as expected: when the Flash is unhidden, it fires its events and correctly initializes everything else (eg. GUI, other internal stuff). The only thing that doesn't happen as expected is that my ExternalInterface callbacks are not added.
ExternalInterface.available is true. It's not a timing problem, because even after several minutes the callbacks are still not present. The strangest bit is that the flash is able to call JS, fires JS events fine, and the code to fire the events comes after the code to add the callbacks. There are no errors thrown by any of the AS3 code. I'm seeing this problem in both Chrome and Firefox.

I'm working on a site that allows administrators to upload arbitrary SWFs and embed them on the page. Administrators are in theory trusted, but I still want to protect against potentially malicious administrators or misguided administrators from harming the site.
A part of the functionality of the site is that the SWFs can communicate to the containing browser page when it's finished and for the page to react.
Now, I can think of two ways to do this:
Use ExternalInterface.addCallback to create a global callback named something like isComplete that does logic and returns true or false depending on whether the Flash app is in a completed state. Then, just do something like setTimeout to just call that function repeatedly. I don't think this would require me to open up allowscriptaccess to the movie. Embed the movie with allowscriptaccess and have the movie call something like ExternalInterface.call('done') when it's finished. This option seems like it requires me to open up allowscriptaccess, which is a potential threat since I can't control the SWFs that would be embedded with this directive.

I am trying to execute an AS3 function from my javascript using the ExternalInterface. Seems to work fine in IE, but firefox is always returning javascript error method undefined.
I have been Googling this for ages and eliminated the following possibilities:
1) Some people say you need to have an embed tag inside your object tag, so added one - no luck.
2) Many people say that you need to make sure that your flash is loaded before calling the javascript. Well my call is after pressing a link on the page. I am always using the flash application first and only pressing the link at the end.
3) Then I thought that maybe it is a security problem so added the following:
try {
ExternalInterface.addCallback("test", testing);
trace("added callback");
