Tips for debugging Angular applications with Firebug

I've encountered an issue while developing an AngularJS app that fetches data from the Firebase cloud. The data is successfully displayed on the page, however, during debugging of my controller, I noticed that the variable appears to be empty. Why is this happening?

Below is the snippet of my controller:

appMainModule.controller('GetCtrl', ['$scope', '$firebaseArray', function ($scope, $firebaseArray) {
  var firebaseObj = new Firebase("URL")
  debugger;
  //var sync = $firebaseArray(firebaseObj);
  //$scope.articles = sync.$asArray();
  $scope.articles = $firebaseArray(firebaseObj);

  var firebaseObj1 = new Firebase("URL");

  $scope.articles1 = $firebaseArray(firebaseObj1.orderByChild("Month").equalTo("Apr-2016"));
  var query=$scope.articles1
  var num = query.length;
}]);

And here is my HTML code:

<div class="content" style="height: 380px; overflow: auto;">
  <table class="table">
    <thead>
      <tr>
        <th>Incident Name</th>
        <th>Category</th>
        <th>Month</th>
        <th>Total</th>
      </tr>
    </thead>
    <tbody ng-repeat="article in articles1 ">
      <tr>
        <td><p>{{article.IncidentName}}</p></td>
        <td><p>{{article.CategoryParent}}</p></td>
        <td><p>{{article.Month}}</p></td>
        <td><p>{{article.Total}}</p></td>
      </tr>
    </tbody>
</div>      

While the HTML page shows the correct articles1 data, the controller displays it as empty after fetching.

Answer №1

After much consideration, I managed to overcome the issue I was facing. It turns out that the delay in my data retrieval was due to the asynchronous nature of the firebase call. Below is the method to handle data when firebase returns a promise:

$scope.articles1.$loaded(function(data){
// perform operations on the data here
})
