AngularJS: Struggling to display modal window with minified AngularJS code

I have successfully created a model dialog using the following JavaScript code, but when I minify the script, I encounter an error preventing the model dialog from opening. The error message states:

        Error: [$injector:unpr] Unknown provider: aProvider <- a
        http://errors.angularjs.org/1.2.11/$injector/unpr?p0=aProvider%20%3C-%20a

Below is the code that successfully opens the model dialog:

HTML:

    <!DOCTYPE html>
    <html ng-app="dialogexample">
    <head>
    <title>Dialog Test</title>
    <link href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"/>
    </head>
    <body>
    <div ng-view=""></div>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.js"></script>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular-route.min.js"></script>
        <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular-resource.min.js"></script>
        <script src="ui-bootstrap-tpls-0.10.0.js"></script>
    <script type="text/javascript" src="appscript.js"></script>
    </body>
    </html>

appscript.js:

    var dialogexample = angular.module('dialogexample', ['ngRoute', 'ui.bootstrap']);
    dialogexample.config(function($routeProvider) {

        $routeProvider
        .when('/dialogpage', {
            templateUrl: "dialogpage.html",
            controller: 'dialogController'
        })
        .otherwise({ redirectTo: '/dialogpage' });
    });

    dialogexample.controller('dialogController', function ($scope, $location, $modal, $rootScope) {

        $scope.openDialog = function() {
            showDialog();
        };

        function showDialog() {

            $modal.open({
              template: '<div>'+
                    '<div class="modal-header">' +
                '<h3>Dialog</h3>'+
            '</div>'+
            '<div class="modal-body">'+
                '<p>'+
                    'Dialog Opened'+
                '</p>'+
            '</div>'+
            '<div class=\"modal-footer\">'+
                '<button class="btn btn-primary" ng-click="ok()">OK</button>'+
                '<button class="btn btn-warning" ng-click="cancel()" ng-hide="hidecancel">Cancel</button>'+
            '</div>'+
        '</div>',
              controller: function ($scope, $modalInstance) {

                  $scope.ok = function () {
                    $modalInstance.close();
                  };

                  $scope.cancel = function () {
                    $modalInstance.dismiss('cancel');
                  };
                }
            });
          };
    });

dialogpage.html

    <div class="partialviewpage">
        <button ng-click="openDialog()">Show Dialog</button>
    </div>

After minifying appscript.js using the steps provided in this tutorial, the resulting minified appscript.min.js file caused the model dialog to fail to open. I would appreciate any guidance on how to solve this issue and successfully display the model dialog with the minified JavaScript.

Thank you for your help.

It's important to properly inject the parameters passed into the controller for $modal.

For example:

    ctrl.$inject = ['$scope', '$modalInstance'];
    ctrl = function ($scope, $modalInstance) {

              $scope.ok = function () {
                $modalInstance.close();
              };

              $scope.cancel = function () {
                $modalInstance.dismiss('cancel');
              };
            };

    $modal.open({
          template: ...,
          controller: ctrl
        });

Note: there may be syntax errors in the code above.

The issue stems from how your services are being injected into the code. Please refer to this resource for more information: https://docs.angularjs.org/tutorial/step_05

Consider this example in your controller:

dialogexample.controller('dialogController', function ($scope, $location, $modal, $rootScope) {...}

Your controller should be structured like this:

dialogexample.controller('dialogController', ['$scope', '$location', '$modal','$rootScope', function ($scope, $location, $modal, $rootScope) { ... }]);

In the controller section of your $modal:

controller: function ($scope, $modalInstance) { ...},

It should be written as follows:

controller: ('modalController', ['$scope', '$modlaInstance', function ($scope, $modalInstance) { ... }]) //add comma after  <)> if other options comes after

Ensure that you update your configuration in a similar manner: It should look like this:

dialogexample.config(['$routeProvider', function($routeProvider) { .. }]);
