angularjs - Get contents of child_added while watching firebaseArray -

i have simple private chat, different type of messages, when send server json structure pass message type too.

$scope.messages = firechat.firebasearray; $scope.addmessage = function(e) {      //add firebase     $scope.messages.$add({         uid: $scope.authdata.uid,         text: $scope.msg,         timestamp: firebase.servervalue.timestamp,         type: 'msg'     });      $scope.msg = ""; //reset message  }; 

as can see there property 'type'.

now i'd watch new messages. in documentation there watch api function, returns id of record/message. i'd contents of message , check type there , according run other js functions.

$scope.messages.$watch(function (data) {     console.log("angularfire watch");     console.log(data);     console.log(data.event);     console.log(data.key);     console.log(data.prevchild); }); 

above return child_added -jp6kzwlydtdetz8agpr , -jp6kzwlydtdetz8ospr. see, no body under key
there possibility key contents? example

switch (key.type) {   case 'paid':     animate_paid(); } 

edit:

$scope.messages.$watch(function (data) {     console.log("angularfire watch");     console.log(data);     console.log(data.event);     console.log(data.key);     console.log($scope.messages.$getrecord(data.key)); }); 

the above code works finally

you can use $getrecord it:

console.log($scope.messages.$getrecord(data.key)); 

you can through api arrays here: https://www.firebase.com/docs/web/libraries/angular/guide/synchronized-arrays.html
