Using JavaScript to interact with Flash

Hello,

My ultimate goal is to load my Flash banner last after all of my images and HTML have finished loading, while still allowing SWFObject flash detection to work.  Here's a description of the SWFObject I'm using:

http://code.google.com/p/swfobject/wiki/documentation

I am using the static publishing method.

I've researched the various ways to force the Flash movie to load last, but I haven't been able to get any of them to work.  One suggestion that had promise was to use two SWF movies.  The first SWF is embedded into my document, and it has two keyframes, with a "stop();" in the first, and the second keyframe loads the main movie I want.  Using Java Script, I tell Flash to play the movie "onLoad", thereby going to the keyframe which loads my movie after everything else has loaded.  It worked very well when I used the conventional way to embed flash into HTML, using both <object> and <embed> tags.  But since SWFObject doesn't embed Flash this way, I believe it's interfering with this, and therefore it only seems to work in IE.  I attached the code below, and you can see an example here:

http://www.livingwaterscommunitychurch.org/example.html

Another clever idea I read was to comment out the part of the HTML I wanted to be loaded last (in this case the Flash div), and then write a function that erases the comments "onLoad", thereby loading my Flash last.  Here's a quote about how to implement this idea:

"Try to put the object tag (<object type="application/x-shockwave-flash" etc.....</object>) containing the .swf file inside a div.

Name the div "myFlash" for arguments sake.
Comment out the object tag as follows:
<div id="myFlash"><!--<object type="application/x-shockwave-flash" ...</object>--></div>

Next: add to the body tag <body onLoad="javascript:reWriteFlash();" ...
then paste this Javascript function::

<script language="javascript" type="text/javascript">
function reWriteFlash(){

var myHTML = document.getElementById("myFlash").innerHTML;

myHTML = myHTML.replace("<!--","");

myHTML = myHTML.replace("-->","");

document.getElementById("myFlash").innerHTML = myHTML;

}
</script>

What this does is on the event "onLoad" (once all HTML is loaded), comments out the object tag and, hence, starts rendering the object and loads the flash file."

When I tried to do this, I failed utterly, so either I don't know how to properly write the code, or something is wrong with the idea itself (it's probably the former).  

Any help with this would be greatly appreciated.  If anyone can show me how to properly implement either of these solutions, or if there's another simpler idea that would allow my Flash to load last without interfering with the SWFObject (assuming it's possible), I'm open to any ideas.

Thanks in advance,
~Coral

I got the "comment out" solution working...I probably just had some errors in my code originally.  I'll post it for anyone who can find it useful.

Hi, basically you have to use javascript and html to embed flash object in your page.
Follow the best practices and you're good to go.
First have a look at this link:

Proper Flash embedding: FlashObject Best Practices:

And this will be more important:

Even the links show how to add variables to your flash object using javascript.
Hope it helped.

Thanks, techExtreme.  That's what the SWFObject is all about, embedding Flash in the page.

I said at the beginning how I'm using the SWFObject, so I guess I'm not really sure what you mean.

Sigh, my "solution" doesn't work afterall. :(  I'm going to have repost this question.

techExtreme, SWFObject both embeds and detects flash all in one simple solution, which is what I want.  I'd rather not use the very bulky detection kit made by Macromedia if I can help it.

techExtreme, I just realized that SWFObject is basically an updated version of FlashObject (developed by the same person).

Finally found an answer...amazingly simple.  It's just a matter of using "display:none" and calling "display:block" onLoad.  Still allows the SWFObject to work perfectly, while loading my Flash content after everything else is finished loading.  It works across browsers.  Yay! :)
