AngularJS 1.8: implementing nested directives and scope inheritance affecting event propagation

angularjs directives scope JavaScript

I'm working on a personal project and I'm working with a question with event propagation in AngularJS 1.8 when using nested custom directives... I have a parent directive that contains a child directive, and I'm trying to handle a click event in the parent directive while also needing the child to respond to the same event. However, it seems like the scope inheritance is causing some unexpected behavior. Hereโ€™s a simplified version of my code: ```javascript app.directive('parentDirective', function() { return { restrict: 'E', scope: {}, template: '<div ng-click="handleClick()"><child-directive></child-directive></div>', controller: function($scope) { $scope.handleClick = function() { console.log("Parent clicked!"); }; } }; }); app.directive('childDirective', function() { return { restrict: 'E', scope: {}, template: '<div>Child</div>', link: function(scope) { // Attempting to handle the click event here scope.$on('childClicked', function() { console.log("Child clicked!"); }); } }; }); ``` In my child directive, I need to also catch the click event from the parent. I tried using `$emit` and `$broadcast`, but it seems like the event is not propagating as expected. When I click on the child directive, the parentโ€™s `handleClick()` function is called, but the child's event handler does not trigger. I expected that clicking on the child directive would call both the parent's and child's click handlers, but only the parent's handler runs. I also tried updating the child directive's scope to inherit from the parent using `scope: true`, but that didn't resolve the scenario. Is there a way to correctly set up the event propagation so both the parent and child can respond to the click? Any insights or examples would be greatly appreciated! What am I doing wrong? I'm working in a Ubuntu 22.04 environment.
