How to detect which swf was loaded

Question

I wonder if it is possible to detect when swf is loaded:

Follow the code:

<object id="teste"  name="teste" type="application/x-shockwave-flash" data="120x600.swf" width="550" height="400" onload="alert('carregado')">
   <param name="movie" value="120x600.swf"/>
   <param name="quality" value="high"/>
   <param name="allowscriptaccess" value="always"/>
   <a href="http://www.adobe.com/go/getflash">
   <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player"/>
   </a>
</object>

* I tried using the parameter onload but it doesn’t seem to work on the Object tag

* Oh also I can not use the swfObject, project limitations.

An alternative is to use the Externalinterface for communication between Javascript and Actionscript. With it it is possible to pass Javascript commands to Actionscript and vice versa.

First you can listen to your SWF load using the code below in the first application frame:

this.loaderInfo.addEventListener(Event.OPEN, iniciouCarregamento);
this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, carregando);
this.loaderInfo.addEventListener(Event.COMPLETE, carregouSWF);

function iniciouCarregamento(e:Event):void {
    trace("Iniciou carregamento");
}

function carregando(e:ProgressEvent):void {
    trace("Carregando..."+Number((e.bytesLoaded/e.bytesTotal)*100));
}

function carregouSWF(e:Event):void {
    trace("Carregou o SWF!");
    ExternalInterface.call("console.log", "Carregou o SWF!"); //Chama uma função do javascript, no caso, o "console.log", e passa como parâmetro a string "Carregou o SWF!"
}

In javascript you can use a custom function and call it by the same method like this:

Javascript:

function escutarSWF(param) {
     console.log(param);
}

Actionscript:

ExternalInterface.call("escutarSWF", "Olá! Eu sou o ActionScript!");

Because the two languages are inherited from Ecmascript, communication between them is effective and functional, I believe you can use them together.

I don’t know if there is any other alternative, but for pure Javascript, I believe this is the most reliable.
