stop after played with javascript

Hello I try to integrate the detection end of reading one page of joomla thanks to all video component reloaded.

my problem is, I can not detect the end of the reading with the javascript. Not being familiar with javascript I used to ask how it looks possible I saw him run on your site.

Here is the code that I insert the player into the page:

the header code is :

<script language="JavaScript">
<!--
// F. Permadi May 2000

var currentState = "NONE";
var previousState = "NONE";

var player = null;
function playerReady(thePlayer) {
player = document.getElementById(thePlayer.id);
addListeners();
}

function addListeners() {
if (player) {
player.addModelListener("STATE", "stateListener");
} else {
setTimeout("addListeners()",100);
}
}

function stateListener(obj) { //IDLE, BUFFERING, PLAYING, PAUSED, COMPLETED
currentState = obj.newstate;
previousState = obj.oldstate;

var tmp = document.getElementById("stat");
if (tmp) {
tmp.innerHTML = "current state: " + currentState +
"<br>previous state: " + previousState;
}

if ((currentState == "COMPLETED")&&(previousState == "PLAYING")) {
document.location.href="http://www.jeroenwijering.com/?item=JW_FLV_Media_Player";
}
}

function getFlashMovieObject(movieName)
{
if (window.document[movieName])
{
return window.document[movieName];
}
if (navigator.appName.indexOf("Microsoft Internet")==-1)
{
if (document.embeds && document.embeds[movieName])
return document.embeds[movieName];
}
else // if (navigator.appName.indexOf("Microsoft Internet")!=-1)
{
return document.getElementById(movieName);
}
}

function StopFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.StopPlay();
}

function PlayFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.Play();
//embed.nativeProperty.anotherNativeMethod();
}

function RewindFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.Rewind();
}

function NextFrameFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
// 4 is the index of the property for _currentFrame
var currentFrame=flashMovie.TGetProperty("/", 4);
var nextFrame=parseInt(currentFrame);
if (nextFrame>=10)
nextFrame=0;
flashMovie.GotoFrame(nextFrame);
}

function ZoominFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.Zoom(90);
}

function ZoomoutFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.Zoom(110);
}

function SendDataToFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
flashMovie.SetVariable("/:message", document.controller.Data.value);
}

function ReceiveDataFromFlashMovie()
{
var flashMovie=getFlashMovieObject("myFlashMovie");
var message=flashMovie.GetVariable("/:message");
document.controller.Data.value=message;
}
