javascript - How to get the main object of a firebase database? -

Here's a very simple question but I can not find an answer anywhere, so hopefully I I can get the answer again by using the keys used in my database:

} {// X is the main object I need}

However, to do this, I need the actual object of the database, the database Not Ndrb. Because when I repeat on the reference, I get a lot of nonsense, so how do I get all the keys by adding personal ones? Hopefully my question comes out.

This can be done like this:

  var value; MyDataRef.on ('value', function (snapshot) {value = snapshot.val ();})
