Im gerade schreiben eine kleine Ajax-Framework für Wiederverwendbarkeit in kleinen Projekten und ich habe ein Problem getroffen. Grundsätzlich bekomme ich ein ' NS_ERROR_ILLEGAL_VALUE ' Fehler beim Senden der Anfrage und ich habe keine Ahnung, was passiert.
Die HTML-Seite (gekürzt, zeigt aber den Fehler)
