如何从角度范围调用外部控制器

Question

I am creating a project using angularJS . Here I have many controllers in different HTML files script section. In my home page file, I have to call these controllers and scope values without referring the scripts in the head section of the HTML page. Is there any possible way to call the external controller from script section without using any third party plugin. Also while analyzing about that I got some suggestion to use resolve option in config. Can you please anyone suggest me to use resolve option to achieve my goal.

Please refer my below code

In my html page,

var mainApp = angular.module("mainApp", ['ngRoute']);
mainApp .config(function ($routeProvider, $locationProvider) {
$routeProvider
    // home page
      .when('/', {
          templateUrl: 'Samples/accordion.html',
          controller: "AddStudentController",
      })
 });

my html section: 
<h1> I am controller 1</h1>
<script>
 <h1>AddStudent</h1>
 mainApp.controller('AddStudentController', function($scope) {
 $scope.message = "This page will be used to display add student form";
  });
</script>

Thanks for any suggestion

Answer 1

If your app loads before the script tags then your angular mainApp will not be recognized and you will get error.

    var mainApp = angular.module("mainApp", ['ngRoute']);
    mainApp .config(function ($routeProvider, $locationProvider) {
    $routeProvider
        // home page
          .when('/', {
              templateUrl: 'Samples/accordion.html',
              controller: "AddStudentController",
          })
     }).controller('AddStudentController',function($scope){
           //first controller
     }).controller('GeStudentController',function($scope){
           //first controller
     });

    my html section: 
    <div ng-controller="AddStudentController">
    <h1> I am controller 1</h1>

     <h1>AddStudent</h1>
    </div>
 <div ng-controller="GetStudentController">
    <h1> I am controller 1</h1>

     <h1>GetStudent</h1>
    </div>
