A question to Flash experts from a beginner: the flash object within a web page

Question

Here\'s my explanation of the question:

From JavaScript, you need to get a reference to the Flash Player object. There are two basic Flash Player versions that ru

Answer 1

Today I got a funny things. I use the common way to embed a flash in my blog.

<object id="flashObject" width="290" height="100" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
    <param name="movie" value="javascriptcallflash.swf" />
    <param name="quality" value="high" />
    <param name="allowScriptAccess" value="always" />
    <embed name="flashObject" width="100%" height="100%" wmode="transparent" allowScriptAccess="always" width="290" height="100" type="application/x-shockwave-flash" src="javascriptcallflash.swf"/>
</object>

And I also use the common way to get the flash reference:

<script type="text/javascript">
    function getFlashMovie(movieName) {   
        var isIE = navigator.appName.indexOf("Microsoft") != -1;
        return (isIE) ? window[movieName] : document[movieName];  
    }
    function CallFlashFun() {
        var textarea = document.getElementById("jsMsg")
        var flashObj = getFlashMovie("flashObject");
        flashObj.asFunction(textarea.value);
    }
</script>

The problem is that after I publish the post. It doesn't work. So I have try to replace window[movieName] to window.document[movieName]. Then it works. It's very weird.

What's the different between window[movieName], document[movieName], and window.document[movieName]?

Answer 2

swfobject.js still does this most reliably. So much so that it's been adopted by Adobe as the default embedding script.

Answer 3

The answer is embedded in the question itself. IE uses object tags and hence SWF is a window object when embedded with object tags. Rest of the world uses embed tags and hence SWF is a property of the window.document for them.
