How can I call Flash function using JavaScript?

[forsiam]

I've seen the example in
http://www.thescripts. com/forum/thread694359.ht ml

but I still have problem about javascript. (I use SWFObject)

My Action Script

import flash.external.ExternalInterface;


var success:Boolean = ExternalInterface.addCallback("thisMethod",this, test);

function test(){
	displayTxt.text = "OK";
}

My Javascript & HTML

<script type="text/javascript" src="swfobject.js"></script>
<SCRIPT LANGUAGE="JavaScript">
<!--
function pause()
{
	var flash = document.getElementById("mymovie");
	flash.thisMethod();
}

//-->
</SCRIPT>

<div id="flashcontent">This text is replaced by the Flash movie.</div>

<script type="text/javascript">
   var so = new SWFObject("test.swf", "mymovie", "200", "80", "8");
   so.addParam("flashvars", "filename=music.mp3");
   so.addParam("allowScriptAccess", "always");
   so.write("flashcontent");
</script>

<INPUT TYPE="button" value="Pause" onclick="pause()">

have anything wrong? thank you
