Incorporate controllers dynamically into your Angular application

Currently, I am incorporating AngularJS into a Backbone.js application. The scenario is as follows: I have one controller (let's call it controller1) which is added to the Angular app from a Backbone view (referred to as view1). Subsequently, I introduced another controller (named controller2) in a different Backbone view (referred to as view2). I added controller2 to the Angular app from view2, but surprisingly the constructor of controller2 does not get called.

view1

bootstarpAngular: function(){

        var app = angular.module('APP', []);
        app.controller('Controller1', ['$scope', loadController1]);

        angular.element(document).ready(function() {
                this.angular = angular.bootstrap(document, ['APP']);
        });
    }

controller1

function loadController1($scope){
   console.log("Controller1");
}

view2

addController2: function(){

            var app = angular.module('APP');
            app.controller('Controller2', ['$scope', loadController2]);
        }

controller2

function loadController2($scope){
   console.log("Controller2");
}

At present, only the console log for controller1 is displayed, not for controller2.

I desire both controllers to be invoked. Could there be an error in my approach, or is there perhaps a better way to achieve this requirement?

Answer №1

If you want to add controllers using the controller function, make sure to do it before initializing Angular's application.

However, if you really need to lazy load a controller, you can achieve this by adding the following code before bootstrapping:

app.config(function($controllerProvider) {
  // globalCtrl must be a global function
  globalCtrl = $controllerProvider.register;
});

Then, in your new module, use the following code:

globalCtrl('Controller2', Controller2Fn);

While there are alternative ways to handle this situation, I would need more information about your specific scenario to provide a more tailored solution.
