I have an AngularJS application, which offers a set of different tasks. In order not to limit myself in the future, I have one main controller, and sub-controllers for each task. The correct sub-controller is selected based on the task’s URL.

However, how do you inject a dynamic controller into the HTML?

Static controllers are easy, <ANY ng-controller="ControllerName"></ANY>

So how do you do dynamic ones?

In StackOverflow there is a very helpful question and answer to this: From an AngularJS controller, how do I resolve another controller function defined in the module?. However it is quite long and slightly incomplete, so here for myself, and anybody out there, the two simple versions which just work:

  1. Don’t! Don’t mess with ng-controller around, let Angular handle it. In my case, every controller had anyway a different view, which was downloaded, and I just defined the controller statically inside the view (<div class="ViewContainer" ng-controller="SpecificViewController">...</div>)

  2. The first option is really nice and simple, but doesn’t always work. The 2nd option is, what you’re probably rather looking for:

You can load the controller via the Controller Service like this: $controller('ControllerName') (optionally, you can inject variables as a second parameter). However, if you want to have the scope injected into the controller, this will throw some exception like

unknown provider scopeprovider …

For it to work, you need to create the scope yourself, so the correct version is:

$controller('ControllerName', { $scope: $scope.$new() });

This will now successfully create the new controller. (Of course you can add additional local variables, if necessary.) The second problem I had, how to use this code together with ng-controller?

First, you need to add the code into the scope, as a function:

$scope.SubController = function() {
  return $controller('ControllerName', { $scope: $scope.$new() }).constructor;
}

Afterwards, you can bind it in HTML simply like this:

<ANY ng-controller="SubController"></ANY>

and everything should work.

Happy Coding!
