parse json data property in angular controller

Question

After reading this posts: parse json data in angular controller

Here is my problem

I have a controller like this

(function() {
  var SomeController = function($scope, someService, $log, $routeParams, ShareData) {
    var colors = function(data) {
      $scope.Colors = data;
      $scope.result = angular.fromJson(data);
      alert($scope.result);

    };

    var errorDetails = function(serviceResp) {
      $scope.Error = "No connection to server";
    };
    someService.colors().then(colors, errorDetails);

  };

  app.controller("SomeController", ["$scope", "someService", "$log", "$routeParams", "ShareData", SomeController]);

}());

This alert returns [object Object],[object Object] When I try to parse one property of this object it returns undefined.

Here is the code.

(function() {
  var SomeController = function($scope, someService, $log, $routeParams, ShareData) {
    var colors = function(data) {
      $scope.Colors = data;
      //here it returns undefined
      $scope.result = angular.fromJson(data);
      alert($scope.result[0].path);

    };

    var errorDetails = function(serviceResp) {
      $scope.Error = "No connection to server";
    };
    someService.colors().then(colors, errorDetails);

  };

  app.controller("SomeController", ["$scope", "someService", "$log", "$routeParams", "ShareData", SomeController]);

}());

The service is OK and it returns two complex objects which have a property named path.

Alert returns [object Object],[object Object] - it means that data is array of objects. So you don't have to parse anything to get data, it's already parsed.

For example, you can access path of the first object in array or construct array of paths:

var colors = function(data) {
  $scope.Colors = data;

  // path from the first object in array
  $scope.result0 = data[0].path;

  // array of paths
  $scope.result = data.map(function(obj) {
     return obj.path;
  });
};

You're not not being very descriptive with your question.

Here's a tip...

Set a breakpoint where the [object Object] is appearing and checkout what your getting.
