How to call dynamically created flash external interface in IE from javascript?

Question

What I have: - A swf exports a function via ExternalInterface - Javascript creates new embed object and adds it to the document - Calling flash functions works fine in other browsers - Calling flash functions will fail in IE 8 Example of exporting functions in swf: ``` flash.external.ExternalInterface.addCallback("isActive", ... ``` Example of creating the embed object: ``` var b = document.createElement('embed'); b.type = 'application\u002fx-shockwave-flash'; b.setAttribute('allowFullScreen', 'true'); b.setAttribute('allowNetworking', 'all'); b.setAttribute('allowScriptAccess', 'always'); b.width = 500; b.height = 400; b.src = 'assets\u002fUltra4.UltraApplication\u002fUltra4.UltraApplication+UltraSprite.swf'; ``` Example of calling flash external interface in javascript: ``` try { e = b.isActive(); } catch (__exc){ } ``` In IE it will catch with message "Object doesn't support this property or method" How to fix it? - Related: http://bojolais.livejournal.com/251383.html - Related: Ex…

I'm not sure if I understand your question correctly. But I think you are missing a couple of things:

1) Your embed tag needs a name attribute. Let's name it "NewFlashMovie" for the subsequent code:

```
b.name = "NewFlashMovie";
```

2) You need to call the "isActive" function differently using an external function. First add this function

```
 function thisMovie(movieName) {
     if (navigator.appName.indexOf("Microsoft") != -1) {
         return window[movieName];
     } else {
         return document[movieName];
     }
 }
```

Then you can call the function like this

`thisMovie("NewFlashMovie").isActive();`

From my experience, this "thisMovie" is essential to bridge the IE-Flash calls. This is also documented in the ExternalInterface documentation

3) I also recommend using swfobject instead of creating your own "embed" object.

Hope these helps.
