Firebase checking to see if data exists

I have a list of random codes with their respective values in my database as follows: 

   123
   |----- value : 1
   877
   |----- value : 2
   245
   |----- value : 1

I want the user to input a value and have Firebase check to see if the code he entered matches any in the database. If it does, it should alert the value of the matched code.

I came up with the following code:

var inputCode = "877"; // user input value
checkCode(inputCode);

function checkCode(inputCode) {
  var ref = new Firebase("https://xxx.firebaseio.com");
  ref.child(inputCode).on('child_added', function(snapshot) {
    alert(snapshot.value);
  });
}

I'm not sure why this isn't working, any suggestions?

Works for me, although the correct syntax is snapshot.val().

var inputCode = "877"; // user input value
checkCode(inputCode);

function checkCode(inputCode) {
  ref.child(inputCode).on('child_added', function(snapshot) {
    console.log(snapshot.val());
  });
}
