How to retrieve data from Firebase using Javascript?

Question

I\'m trying to access \"id\" and store it in a variable. So far the code I have is:

var ref = firebase.database().ref(\"users\");

ref.on(\"value\", fun         


        

Answer 1

You need to get key of parent-node(L2L6vBsd45DFGfh) to access id child

When you use push() method in firebase it will automatic generate unique key for your record. use set() or update() method to create your own custom keys.

var ref = firebase.database().ref("users");
ref.on("value", function(snapshot) {
    var childData = snapshot.val();
    var key = Object.keys(childData)[0];    //this will return 1st key.         
    console.log(childData[key].id);
});

You will use for-loop or forEach to get all keys.
