Even though it's related to IE and the COM+ bridge, that still doesn't mean that flash couldn't implement js functions that mapped to those COM+ function callbacks. That way we could interact with the callbacks in the same way as other JS functions, which would be a lot more flexible. They do it with their magical __flash_to_XML() functions and such, I don't know why they couldn't do it with all callbacks. Just my 2 cents.

It's due to ActionScript/JavaScript communication over the COM+ bridge; IE will not return a proper typeof and will simply say "unknown". It isn't a bug, it's a 'feature' implemented by Microsoft. Quote from comment by Tom Trenka (of dojotoolkit) near the bottom of this blog post: Internet Explorer displays “unknown” when the object in question is on the other side of a COM+ bridge. You may not know this or realize this, but MS’s XMLHTTP object is part of a different COM+ object that implements IUnknown; when you call methods on it, you’re doing so over a COM bridge and not calling native JavaScript. Basically that’s MS’s answer if you try to test or access something that’s not a true part of the JScript engine. Very obscure, indeed. - philip On Tue, Jun 16, 2009 at 7:32 AM, Getify Solutions, Inc. <[email protected]> wrote: Yes, as I said, the "functions" that the flash plugin exposes on a swf object in your DOM are not true JS functions, they are special callbacks handled by the activeX control. There are other things you can normally do with JS functions, that you can't do with them, like use ".call()" or ".apply()" on them. It's frustrating. In fact, I've filed a bug with Adobe a long time ago on a very similar topic, they still haven't addressed it: http://bugs.adobe.com/jira/browse/FP-254 So it's not surprising to me that the typeof() is reporting wrong on those "functions". FWIW, CheckPlayer implements logic that continually tries in a setTimeout loop to call a certain "function" on the swf, with a try/catch, and as soon as it doesn't catch an error, it knows that the function is ready to go. You could try something similar to that. --Kyle -------------------------------------------------- From: "marekful" <[email protected]> Sent: Tuesday, June 16, 2009 9:12 AM To: "SWFObject" <[email protected]> Subject: Re: 'unknown' type of members in object in IE > > Actually it's more than just strange... > > embedSWF works fine, the flash is displayed in all browsers. > Then, in a button's onlick handler: > > var obj = document.getElementById("myFlashObj"); > /* > typeof obj.SetVariable // 'unknown' in IE7, 'function' in FF > obj.SetVariable // null in IE7, 'function SetVariable { [native > code] }' in FF > */ > obj.SetVariable('myvar','myvalue'); // WORKS in IE7 and FF > > > Any thoughts? > > Regards, > //m > > On Jun 16, 2:58 pm, marekful <[email protected]> wrote: >> Hi Kyle, >> >> Yes, I've tested the situation with the traditional way and the same >> happend. >> No, no forms. >> >> The SOLUTION is that there's no need for solution.
