The Ultimate Guide for Formatting JSON Data from Firebase

I'm facing an issue with parsing JSON data returned by Firebase. Here is the JSON snippet:

{
  "-JxJZRHk8_azx0aG0WDk": {
    "email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="cda6a68daaa0aca4a1e3aea2a0">[email protected]</a>",
    "firstname": "dasd",
    "lastname": "sadd",
    "password": "dasdasd"
  }
}

I am trying to access the email field from this JSON. Below is a snippet of my controller code:

var ref = new Firebase('url');
console.log($scope.user.email);
ref.orderByChild('email')
   .startAt($scope.user.email)
   //.orderBy('length')
   //.startAt(10)
   .on('value', function(snapshot) { 
        console.log(JSON.stringify(snapshot.val(), null, 2));
}

If anyone can provide assistance, I would greatly appreciate it.

To implement this, follow these steps:

function MyCtrl($scope) {
  $scope.user1 = {
    "-JxJZRHk8_azx0aG0WDk": {
      "email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="e98282a98e84888085c78a8684">[email protected]</a>",
      "firstname": "dasd",
      "lastname": "sadd",
      "password": "dasdasd"
    }
  };
  $scope.email1 = $scope.user1[Object.keys($scope.user1)[0]].email;
   $scope.user2 = {
    "-dfdhfhdfh": {
      "email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1e7d7a687a6875755e79737f7772307d7173">[email protected]</a>",
      "firstname": "dasd",
      "lastname": "sadd",
      "password": "dasdasd"
    }
  };
  $scope.email2 = $scope.user2[Object.keys($scope.user2)[0]].email;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app ng-controller="MyCtrl">
  email Id 1:{{email1}}
  <br>
  email Id 2:{{email2}}
</div>
