Question

Can someone provide a method to access the namespace of an Angular controller when utilizing the "Controller As" format?

Imagine you have an AngularJS ngController directive set up like this:

<div ng-controller="SomeCtrl as herpderp">…</div>

Is there a way to extract the namespace ("herpderp") from within the SomeCtrl controller itself? This could be useful for scenarios where you need to reference that specific controller instance in other parts of your application, or keep track of the controller under a more descriptive name instead of relying on $scope.$id.

Clarification / update: I am aware that within my controller code, I can access $scope.herpderp—in the example given. However, the issue arises when I have multiple instances of the same controller on a page, each with a different alias. In such cases, the $scope property (e.g., herpderp) will vary depending on how the controller is instantiated. Therefore, in the situation mentioned above, I would like to find out what "B" represents in ng-controller="A as B" (SomeCtrl as herpderp).

Are you trying to determine how a controller was created from your controller? For example, whether it was created as MyCtrl as A or MyCtrl as B. If that's the case, you can achieve this by using the following code snippet.

for (key in $scope) {
    if ($scope[key] === this) {
        // If the controller was created as "MyCtrl as X", then this will log "X"
        console.log(key);
    }
}

When utilizing the controller as syntax, your controller remains connected to the scope. This means you can access something on your controller by using $scope.herpderp.foo. Inside the controller itself, you can simply use this.foo to access the same variable. In HTML, you would reference it as herpderp.foo.

I hope this clarifies what you were inquiring about.
