Firebase - Detaching Callbacks


This chapter will show you how to detach callbacks in Firebase.


Detach Callback for Event Type

Let us say we want to detach a callback for a function with value event type.


Example

var playersRef = firebase.database().ref("players/");

ref.on("value", function(data) {
   console.log(data.val());
}, function (error) {
   console.log("Error: " + error.code);
});
				

We need to use off() method. This will remove all callbacks with value event type.


playersRef.off("value");
				

Detach All Callbacks


When we want to detach all callbacks, we can use −

playersRef.off();
