AngularJS access controller $scope from outside

Solution 1:

Without seeing the markup, I guess the scope of MenuSideController is a child scope to the scope you are selecting.

While it is possible to traverse down the tree like this (assuming the scope we want is the first child):

var appElement = document.querySelector('[ng-app=theApp]');
var appScope = angular.element(appElement).scope();
var controllerScope = appScope.$$childHead;
console.log(controllerScope.user);

It is simpler to just select the element where the specific controller is attached.

Assuming you are using the ng-controller directive:

<body ng-controller="MenuSideController"></body>

Do instead:

var controllerElement = document.querySelector('body');
var controllerScope = angular.element(controllerElement).scope();
console.log(controllerScope.user);

angular.element(document).ready(function() {

  var appElement = document.querySelector('[ng-app=theApp]');
  var appScope = angular.element(appElement).scope();

  console.log('Traversing from appScope to controllerScope:', appScope.$$childHead.user);


  var controllerElement = document.querySelector('body');
  var controllerScope = angular.element(controllerElement).scope();

  console.log('Directly from controllerScope:', controllerScope.user);


  controllerScope.$apply(function() {
    controllerScope.user.zoomlvl = '10';
  });
});
