AngularJS 1.8: implementing ng-class implementation guide dynamically with nested scopes
I'm reviewing some code and This might be a silly question, but I'm having a hard time understanding I'm optimizing some code but I'm experiencing a question with `ng-class` not updating as expected when I'm working with nested scopes in AngularJS 1.8..... I have a parent controller that sets a class based on a condition, and this condition is supposed to update when a child controller modifies a variable. Here’s a simplified example of my code: ```javascript angular.module('myApp', []) .controller('ParentController', function($scope) { $scope.isActive = false; }) .controller('ChildController', function($scope) { $scope.toggleActive = function() { $scope.isActive = !$scope.isActive; }; }); ``` And in my HTML: ```html <div ng-controller="ParentController"> <div ng-class="{'active': isActive}"> Parent: <button ng-click="activate = !activate">Toggle Parent</button> </div> <div ng-controller="ChildController"> <div ng-class="{'active': isActive}"> Child: <button ng-click="toggleActive()">Toggle Child</button> </div> </div> </div> ``` The scenario I'm working with is that when I click the button in the child scope to toggle `isActive`, the class is not being applied as expected. The class is only applied to the parent div and not to the child div, even though `isActive` is being updated in the child controller. I’ve checked that `isActive` is indeed changing its value, but the `ng-class` does not react to this change in the child scope. I’ve tried using `$scope.$parent.isActive` in the child controller, but then the class doesn't toggle properly as it only references the parent’s scope. I also checked for any errors in the console but there’s nothing indicating a question. How can I get `ng-class` to correctly reflect the changes to `isActive` from the child controller? Any help would be appreciated! This is part of a larger service I'm building. What's the best practice here? I'd really appreciate any guidance on this. This is my first time working with Javascript stable. Any ideas how to fix this? I'm coming from a different tech stack and learning Javascript. Any advice would be much appreciated. I'm working in a macOS environment. I appreciate any insights! This is my first time working with Javascript 3.9.
