Ich habe eine JS-Klasse erstellt, um SG / Folder-Listenansichtsdaten zu füllen, wenn Elemente geändert werden. ( Gemäß Jaimes Ansatz) Alles funktioniert hervorragend, wenn ich Elemente in der Publikation bearbeite, in der sie erstellt wurden.
Beispiel: Ich öffne eine Komponente oder Seite und die benutzerdefinierte locked by
Spalte wird sofort aktualisiert und zeigt meinen Benutzernamen an.
Wenn ich jedoch zu einer untergeordneten Publikation gehe und diesen Vorgang wiederhole, wird im Fenster gefragt, ob ich das übergeordnete Element lokalisieren oder bearbeiten möchte. Wenn ich das übergeordnete Fenster bearbeite, funktioniert der Code nicht. Ich habe es beim ersten Debuggen noch nicht ganz herausgefunden. Chrome scheint den Fehler zu verschlucken, Firefox gibt mir eine kryptische:
Zeitstempel: 22.06.2012 15:42:54 Uhr
Fehler: nicht erfasste Ausnahme: [Ausnahme ... "Von der Komponente zurückgegebener Fehlercode: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOINTERFACE)" Speicherort: "JS frame :: chrome: // browser / content / tabbrowser .xml :: :: Zeile 545 "Daten: nein]
Hat jemand erste Ideen? Ich werde später versuchen, einen Code zu veröffentlichen ...

Sie alles aufundefined
. Dies kann zu einem Problem führen, wenn Sie ein Attribut definieren und ihm dann mitteilen, dass es undefiniert ist - was keinen Sinn ergibt. Es ist besser, den Anfangswert auf festzulegen,null
wenn Sie keinen Wert möchten. Wie gesagt, das spielt wahrscheinlich keine Rolle, es sei denn, ein anderer Code sucht nach definierten Schlüsseln.undefined
Überprüfungen, die ich gesehen habe, sindtypeof something === 'undefined'
mit ===, == ,! = Oder! == Also, Sie könnten versuchen, setTimeout zu verwenden, um setXml nach getOuterXmlAntworten:
Dies bedeutet, dass dem nsIWebProgress- Objekt kein Fenster zugewiesen wurde . Es gibt also keinen Ort, an dem Daten angezeigt werden können.
Hier erfahren Sie, welche Datei mit diesem Fehler verbunden ist. und auf welcher Leitung es fehlerhaft war.
Der eigentliche Schlüssel ist jedoch der Fehler NS_NOINTERFACE. Dies bedeutet, dass die Schnittstelle nicht registriert wurde.
Sie verwenden
Type.enableInterface()
. Ist das eine benutzerdefinierte Methode, die Sie woanders deklarieren? Ich sehe es nicht Vielleicht möchten Sie das ändern in.registerInterface()
Siehe diesen Link Typklasse und Type.registerInterface ()
