JSON untergeordnete Objekte geben undefinierte Werte zurück

Ich habe JSON mit verschiedenen untergeordneten Objekten (Scans) unten gezeigt. Ich versuche Inhalte von Kind-Objekten mit Javascript zu drucken, es gibt mir eine Ausgabe 'undefiniert'.JSON untergeordnete Objekte geben undefinierte Werte zurück

JS Fiddle Link: https://jsfiddle.net/jpavanaryan/sz5gkesh/

alert(jsonobj.scans[0]);

Bitte den gesamten Code aus jsfiddle enthalten, denn wenn die jsfiddle jemals verschwindet, nimmt auch die Rahmen Ihrer Frage. Oder noch besser, posten Sie Ihren Code als Snippet, damit er direkt von Ihrem Post aus ausgeführt werden kann. Vielen Dank! – TheJim01

Sie versuchen, es zu drucken, bevor Sie das Objekt erstellen ?! – Bergi

scans ist eine weitere Aufgabe und Sie versuchen, einen Index zu verweisen. Also, wenn Sie tun scans[0] - es ist tatsächlich auf der Suche nach dem Schlüssel "0" innerhalb von scans, die nicht existiert. Verwenden Sie einen Schlüssel:

jsonobj.scans["VX Vault"].result

Sie kennen die Schlüssel nicht? Dann iterieren mit einem for in loop:

for (var key in jsonobj.scans) { 
    console.log(jsonobj.scans[key]); 
}

Ich habe mehr als 30 Schlüssel in JSON, also suchte ich nach einem generischen Weg für die Iteration. –

@Jadda - Siehe mein Beispiel für die Iteration. – tymeJV

Ich arbeitete. Danke tymeJV :) –

Die Eigenschaft jsonobj.scans ist ein assoziatives Array. Auf jeden Scan muss mit dem Namen jsonobj.scans['scanname'] zugegriffen werden, oder er kann mit dem for ... in Konstrukt nummeriert werden.
