How can I find the scope of a loaded controller? I want to trigger an event after the scope is initialized in order to predefine the model for the view.

$rootScope.$on("$controllerLoaded")How can I find the scope of a loaded controller? I want to trigger an event after the scope is initialized in order to predefine the model for the view.
Is there a way to listen for
$rootScope.$on("$controllerLoaded")It appears that you are looking for a way to alert another section of an app once a specific controller has been loaded. Is my understanding correct?
If so, there are a couple of approaches you can take. One option is to explore the usage of $emit, which essentially sends a signal to parent listeners.
For more information on using $emit and $broadcast, check out this informative article.
$rootScope.$on('emitName', function(){
//perform desired actions here
});
Alternatively, you could set a flag at the conclusion of your controller (although considered more of a workaround):
$rootScope.controllerLoaded = true
Then, in the location where you need to be notified of its completion, simply check the $rootScope.controllerLoaded flag.
To incorporate this functionality within your controller, simply assign the desired value to the $scope variable.
function GreetingCtrl($scope) {
// a basic string
$scope.greeting = 'Hello!';
// a more elaborate example
$scope.myModel = {id:2, name:'Sarah'};
}
You can then utilize this in your view:
<label>{{myModel.name}}</label>
This will display a label containing 'Sarah' (which will automatically update as you modify your model).
As your application progresses, you may need to fetch data from a server database using either $http or $resource. Refer to the provided links for guidance on initializing your model with data from these modules.
For additional information, consult the Controller documentation.
