Oldperl hat geschrieben:sorry, aber das verstehe ich nicht ganz wieso du da einen onlaod brauchst.
Du kannst doch das anzuzeigende Bild gleich beim Laden anhand deiner idcat gleich richtig laden und nicht erst ein Standardbild. evtl. könnte man dann im entsprechenden Bildmodul noch abfragen, ob das Bild vorhanden ist und ansonsten ein Standardbild anzeigen.
Der onload ist IMO nicht notwendig. Nur zum Preload der Bilder brauch man dann einen, der gehört dann aber in den body-Tag und man bräuchte ein Modul was diesen Preload mit allen Bilder im Verzeichnis läd auser dem das eh angezeigt wird.

Das verstehe ich grundsätzlich. Ich lege also ein Modul an, welches das Originalbild anzeigt und DORT ist die onLoad-Funktion drin, die dann die IDCAT als Namen für die Bilddatei benutzt, richtig?!
Aber wie geht das? Stelle mich ziemlich blöd an, wenn es um "neue" Dinge geht. Bin schon froh, dass ich vorhandene Sachen leicht modifizieren kann.
Wie würde das Modul aussehen, in dem ich passend zur HAUPTkategorie (!) ein Bild austausche?
Kann ich das aus dem Hauptnavi-Modul irgendwie rausnehmen:
