Das Problem ist, dass, wenn ich diese HTML-Datei ausführen und klicken Sie auf „editSubSubject“ -Taste nichts passiert. Die JavaScript-Funktion wird nicht aufgerufen. Wenn ich die Parameter dieser Funktion entferne und sie wie folgt aufrufe: onClick = "updateSubSubject()" funktioniert es einwandfrei und öffnet den Dialog,
Was ist falsch in meinem Code?
Wie kann Ich mache das, wenn ich ein Objekt oder eine Zeichenfolge senden möchte, die ein Teil eines Objekts wie folgt ist: myObj.myString Ich mache sowas wie dieses, aber es funktioniert nicht .. Ich muss nicht hinzufügen, weil es String myObj sein wird .myString ', Wie kann ich das machen? – user6319790
@ user6319790 Nein, das ist nicht der Fall, sonst wäre es der Text "myObj.myString" 'und nicht der Wert" myObj.myString ". Sie können einfach 'updateSubSubject (myObj.myString)'. –
Ok das ist das Problem, dass updateSubSubject (myObj.myString) nicht funktioniert .... die Übersetzung von diesem bei der Verwendung von F12 ist updateSubSubject (myObj.myString) und nicht der Wert von myObj.myString ... Was kann ich tun? – user6319790
