Site opent niet in IE, waarschijnlijk door javascript

[Mikethabest]

Hi!

Op mijn website maak ik gebruik van tabs; via javascript dynamisch content openen.
Hiervoor heb ik gebruik gemaakt van http://www.dynamicdrive.com/dynamicindex17/ajaxtabscontent/index.htm

Nu is alles goed en wel in Firefox en Chrome, maar in IE opent hij de site totaal niet.
Stel ik heb www.google.nl open en surf naar mijn site, dan gebeurt er niets, google blijft staan. Google is echter niet meer te gebruiken en af en toe is er een mouseover van andere elementen op mijn site, maar de site is dus totaal niet zichtbaar.

Hieronder staan alle relevante codes.

Ik heb op mijn pagina in head een verwijzing naar tabs.js, zie hieronder tabs.js.

//** Ajax Tabs Content script v2.0- © Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
//** Updated Oct 21st, 07 to version 2.0. Contains numerous improvements
//** Updated Feb 18th, 08 to version 2.1: Adds a public "tabinstance.cycleit(dir)" method to cycle forward or backward between tabs dynamically. Only .js file changed from v2.0.
//** Updated April 8th, 08 to version 2.2:
// -Adds support for expanding a tab using a URL parameter (ie: http://mysite.com/tabcontent.htm?tabinterfaceid=0)
// -Modified Ajax routine so testing the script out locally in IE7 now works

Aan het einde van de pagina zelf:
[JS]<script type="text/javascript">
// site menu = menu: no duplicate var names
var sitemenu=new ddajaxtabs("menu", "homecontainer")
sitemenu.setpersist(true)
sitemenu.setselectedClassTarget("link") //"link" or "linkparent"
sitemenu.init()
</script>[/JS]

Als menu:
Voor home:
<a href="#" class="selected" rel="#default" id="home"><img border="0" src="images/home.png" onMouseOver="this.src='images/home_m.png'" onMouseOut="this.src='images/home.png'"></a>
Voor andere items:
<a href="page.php?p=page" rel="homecontainer" id="page1"><img border="0" src="images/page1.png" onMouseOver="this.src='images/page1_2.png'" onMouseOut="this.src='images/page1.png'"></a>

Op de site is dus een div homecontainer waarin de content geladen wordt.

Wie weet hoe dit op te lossen voor IE?

Als ik de demo's bij dynamicdrive.com met IE7 bezichtig, doen ze het allemaal. Het script op zich lijkt dus goed (niet getest in IE8).

Als ik de code van hierboven vergelijk met de demo-codes, lijkt het ook in orde te zijn.

Voorlopige conclusie: het zal aan iets anders in je code liggen, die elders op je pagina staat. Als je javascript in IE uitschakelt, is er dan wel iets te zien?

• Zo nee, dan ligt het waarschijnlijk helemaal niet aan het script, maar zou het bv. een css-uitglijer van Internet Explorer kunnen zijn.

En is de pagina al valid html en valid css bevonden?
