Firebase returning [object Object]

Question

I have the following problem. The code recognizes that there is something and shows all the entries, but not the content, but only displays [object object]. I really want to read everything that is in the category "abgeschlosseneAuftraege" and also all subcategories. But for now I try to read at least 1 entry. I would be very grateful for help.

firebase.database().ref("/abgeschlosseneAuftraege").on('value', function(snapshot){
  let elm = document.getElementById("data");
  elm.innerHTML = '';

  snapshot.forEach(function(childSnapshot){
    var childKey = childSnapshot.key;
    var childData = childSnapshot.val();
    elm.innerHTML += childData['Accepted'];
  })
})
    getData();

childSnapshot.val() must be returning an object. not a string. — rlemon

[object Object] is what you get when you use an object where a string is required. So childData['Accepted'] must be an object. What does console.log(childData['Accepted']) show? — Barmar

@rlemon childSnapthot.val() has to be an object so you can use childData['Accepted']. — Barmar

@Barmar elm.innerHTML += console.log(childData['Accepted']); elm.innerHTML + = console.log (childData ['Accepted']); shows all entries, but instead of object object it shows undefined undefinedundefined ... — David Schober

childData['Accepted']; is an object, not a string. If you want to see a representation of it, use JSON.stringify().

    elm.innerHTML += JSON.stringify(childData['Accepted']);
