Script does not work?!

[man]

Hi folks, this script check´s up if my Server is on, but if the Server is on or off, every time i was linked to the Go.htm.
Why? Is there s.th. wrong in this Script?

<script language="JavaScript">
Bild = new Image(); Bild.src = "http://hackstube.homeip.net/mmc.gif";
var loop = 4, hoch = 24;
function Servertest()
{
if(Bild.height == hoch)
window.location.href="http://www.hackstube.de/Go.htm";
else if (loop>0)
{loop--; window.setTimeout("Servertest()",1000);}
else
window.location.href="http://www.hackstube.de/Stop.htm";
}
Servertest();
</script>

At this time my Server is realy off! So you can test the script...

You might like something like this better:

<script type="text/javascript">

var img = new Image();
img.src = 'http://www.yourdomain.com/images/someimg.png';
img.onload = function () {document.getElementById("online").style.backgroundColor="#00ff00";}
img.onerror = function () {document.getElementById("online").style.backgroundColor="#ff0000";}

</script>

Server Status: <span id="online" style="width: 10px; height: 10px; background-color: transparent; font-size: 1px;"></span>

[man]

thx for your Version, looks good and after a test it realy works fine when Server is off, but it takes about 20 seconds to display the red color. That´s to long...

Do you have an other idea?

If it would be possible with the redirection Links like the example in the first post.

[man]

I also tried this script but it takes about 20 second to check server status, too!

<script TYPE="text/javascript">
var on_line = "No";
</script>
<script type="text/JavaScript" src="http://my_domain.com/on-line.js"></script>
<script TYPE="text/javascript">
if (on_line != "Yes")
document.write("Server is offline<br>");
else
document.write("Server is online<br>");
</script>

If what pyro suggested is taking 20 secs then thats how long your image takes to preload?..use a smaller image...

[man]

If the Server is off, what image will be loaded?

The problem is the off message. It takes 20 seconds to say "Tere is no Server"! To long i think.

[man]

OK Folks it was my fault!!

I made the mistake to put the complet Code into the body ...

As i put the script part into the head it wondered how fast it was.... so it works perfect!

Thx for your support!

You bet. Glad it's working for you... :)

[man]

How must the script look like if i want to offer a Link for this part...

img.onload = function () {document.getElementById("online").style.backgroundColor="#00ff00";}

...so that the user can go to the Server!?

For example http://hackstube.homeip.net

Try it like this:

<script type="text/javascript">

var img = new Image();
img.src = "http://www.yourdomain.com/images/someimg.png";
img.onload = function () {
document.getElementById("online").style.backgroundColor="#00ff00";
document.getElementById("onlinelink").innerHTML = "<a href=\"http://www.yourdomain.com\">http://www.yourdomain.com</a>";
}
img.onerror = function () {
document.getElementById("online").style.backgroundColor="#ff0000";
}

</script>

<p>Server Status: <span id="online" style="width: 10px; height: 10px; background-color: transparent; font-size: 1px;"></span><span id="onlinelink"></span></p>
