Firebase update callback to detect error and sucssess

Question

How do I make this call back work? I have read the documents but I just cant figure it out for some reason?

   var ref = new Firebase(\"https://xxx.firebasei

Frank's solution is perfect for your question. Another option is to use the update promise. It's particularly useful if you're doing a bunch of operations together which is often the case in Firebase.

here's an example using a promise

blast.update({ update: "I'm writing data" }).then(function(){
  alert("Data saved successfully.");
}).catch(function(error) {
  alert("Data could not be saved." + error);
});
