Hallo,

Ich bekomme im IE8 und auch im Firebug immer "'this.tableNavi.childNodes.2.nodeValue.length' ist Null oder kein Objekt

Ich habe es mit Opera, FF und dem IE probiert - keine Fehlermeldung. Firebug habe und nutze ich nicht, da es bei JS Problemen mir nicht mehr hilft als als die Fehlerkonsole.

Ich habe den Code noch mal umgeschrieben, teste ihn bitte noch mal!

Zum leeren SPAN, das wird für abgerunde Ecken benötigt.

Struktur und Designtrennung

Dein SPAN ist dabei...

Micha
