AngularJS + Typescript controller cant be found - javascript

I am trying to add typescript to AngularJS and I'm getting the following error
Error: [$controller:ctrlreg] The controller with the name 'MyController' is not` registered
Has anyone clue on what I am doing wrong?
I have created the following class
/// <reference path='references/_all.ts' />
var app = angular.module('shop', []);
class MyController {
constructor($scope: any) {
$scope.message = { title: "Hello World!!" };
};
}
app.controller('MyController', MyController);
and html:
<html>
<head>
...
</head>
<body ng-app="shop">
<div ng-controller="MyController">
{{message.title}}
</div>
</body>
</html>
I am using grunt to compile it:
/// <reference path='references/_all.ts' />
var app = angular.module('shop', []);
var MyController = (function () {
function MyController($scope) {
$scope.message = { title: "Hello World!!" };
};
return MyController;
})();
app.controller('MyController', MyController);

Do you have link file with app?
<script src="./app.js"></script>
Here is my solution:
var app = angular.module('shop', []);
var MyController = (function () {
function MyController($scope) {
$scope.message = { title: "Hello World!!" };
}
return MyController;
})();
app.controller('MyController', MyController);
<head>
<meta charset="utf-8" />
<title>AngularJS + Typescript controller cant be found</title>
<script src="https://code.angularjs.org/1.5.4/angular.js"></script>
<script src="./app.js"></script>
</head>
<body ng-app="shop">
<div ng-controller="MyController">
{{message.title}}
</div>
</body>
</html>

How to use Angular with Require in javascript classes

I have been playing around with angular and would like to add it to application using require. I have a class called Test that is wrapped around a require for Angular. The problem is that if I do not initialize the angular.module directly under the require statement for angular, I get an error saying Uncaught Error: [$injector:modulerr]
<!DOCTYPE html>
<html>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.3/require.min.js"></script>
<script>
require.config({
paths: {
"angular": "https://ajax.googleapis.com/ajax/libs/angularjs/1.6.2/angular.min"
}
});
</script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
Name: <input ng-model="name">
<h1>You entered: {{name}}</h1>
</div>
<script>
require(['angular'], function () {
var Test = class Test {
constructor() {
this.setAngular();
};
setAngular() {
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.name = "John Doe";
});
}
}
});
var test = new Test();
</script>
</body>
</html>
However, if I move the require statement down to inside the setAngular function like so:
setAngular() {
require(['angular'], function () {
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.name = "John Doe";
});
});
}
Then everything works fine. Am I missing something here?

Hey, this is part from application when I use ngRoute and dynamically add home.html, but I think I have wrong app.js or home.controller.js beacuse when I add external file home.js (when is ng-controller=""RedCtrl. I get error [$controller:ctrlreg] RedCtrl is not register. Have you ideas why? I am new in Angular and I think the main reason is lack of my knowledge.
You are overwriting app module in home.js thus getting the error
Use
var app = angular.module('app'); //Get previously defined module
instead of
var app = angular.module('app', []); //It declares new module
You also need to change the sequence of JavaScript files
<script src="app.js"></script>
<script src="home.js"></script>

Problems with uploading a file and parsing with AngularJS

Trying to build a simple application that allows a user to upload a file, and upon clicking the 'add' button, It parses the file and displays the result within the browser.
I am using IntelliJ to generate the AngularJS application stub, and modifying it accordingly.
My attempt is below:
view1.html
<!DOCTYPE html>
<html lang="en" ng-app>
<head>
<meta charset="utf-8">
<title>My HTML File</title>
<link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css">
<link rel="stylesheet" href="../app.css">
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/ng-file-upload/ng-file-upload-shim.js"></script> <!-- for no html5 browsers support -->
<script src="bower_components/ng-file-upload/ng-file-upload.js"></script>
<!--<script src="view1.js"></script>-->
</head>
<body>
<div ng-controller="View1Ctrl">
<input type="file" id="file" name="file"/>
<br/>
<button ng-click="add()">Add</button>
<p>{{data}}</p>
</div>
</body>
</html>
view1.js
'use strict';
angular.module('myApp.view1', ['ngRoute'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/view1', {
templateUrl: 'view1/view1.html',
controller: 'View1Ctrl'
});
}])
.controller('View1Ctrl', ['$scope', function ($scope) {
$scope.data = 'none';
$scope.add = function() {
var f = document.getElementById('file').files[0],
r = new FileReader();
r.onloadend = function(e) {
$scope.data = e.target.result;
}
r.readAsArrayBuffer(f);
}
}]);
view1_test.js
'use strict';
describe('myApp.view1 module', function() {
beforeEach(module('myApp.view1'));
describe('view1 controller', function(){
it('should ....', inject(function($controller, $rootScope) {
//spec body
// var view1Ctrl = $controller('View1Ctrl');
var $scope = $rootScope.$new(),
ctrl = $controller('View1Ctrl', {
$scope: $scope
// $User: {}
});
expect(ctrl).toBeDefined();
}));
});
});
app.js
'use strict';
// Declare app level module which depends on views, and components
angular.module('myApp', [
'ngRoute',
'myApp.view1',
'myApp.view2',
'myApp.version'
]).
config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/view1'});
}]);
I am not sure where I could potentially be going wrong? I viewed quite a few questions to this and tried multiple different approaches but I cannot get this to work despite all of my tests passing.
The issue was around my view1.js file. I found the Papa Parse library extremely useful.
Here is my solution used from the open source Papa Parse community:
Papa.parse(fileInput[0], {
complete: function(results) {
console.log("Complete!", results.data);
$.each(results.data, function(i, el) {
var row = $("<tr/>");
row.append($("<td/>").text(i));
$.each(el, function(j, cell) {
if (cell !== "")
row.append($("<td/>").text(cell));
});
$("#results tbody").append(row);
});
}
});

AngularJS: Browser ignores my Controller Definition (Dependency Injection)

I am using angular-translate in my project but I am unable to define a controller that has a dependency injection of $translate. The code isn't executed in the browser. I checked JSHint already...
index.html
<html ng-app='ngApp'>
<body>
<div ng-controller="orderFormCtr">
<ul>
<li>{{'TITLE' | translate}}</li>
<li translate="TITLE"></li>
</ul>
</div>
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-translate/angular-translate.js"></script>
<script src="app.js"></script>
</body>
</html>
app.js
angular.module('ngApp', ['pascalprecht.translate']);
// this code works
angular.module('ngApp').config(['$translateProvider', function ($translateProvider) {
$translateProvider.translations('en', {
TITLE: 'Hello'
});
$translateProvider.translations('de', {
TITLE: 'Hallo'
});
}]);
// the browser ignores this code
angular.module('ngApp').controller('orderFormCtr', ['$scope', '$translate', function ($scope, $translate) {
alert("Controller Code executed");
}]);
var app = angular.module('ngApp', ['pascalprecht.translate']);
// this code works
app.config(['$translateProvider', function ($translateProvider) {
$translateProvider.translations('en', {
TITLE: 'Hello'
});
$translateProvider.translations('de', {
TITLE: 'Hallo'
});
$translateProvider.preferredLanguage('en');
//or translateProvider.determinePreferredLanguage()
}]);
// the browser ignores this code
app.controller('orderFormCtr', ['$scope', '$translate', function ($scope, $translate) {
alert("Controller Code executed");
}]);

Angularjs app not working after adding new controller

Initially my controller.js looked like this
function MyCtrl1() {}
MyCtrl1.$inject = [];
function MyCtrl2() {
}
MyCtrl2.$inject = [];
And the html code like this
<!doctype html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="utf-8">
<title>My AngularJS App</title>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
<script src="http://angular-ui.github.com/bootstrap/ui-bootstrap-tpls-0.2.0.js"></script>
<link rel="stylesheet" href="css/app.css"/>
</head>
<body>
<ul class="menu">
<li>view1</li>
<li>view2</li>
</ul>
<div ng-view></div>
<div>Angular seed app: v <span app-version></span></div>
<div>Author is : <span app-author></span></div>
<script src="js/app.js"></script>
<script src="js/services.js"></script>
<script src="js/controllers.js"></script>
<script src="js/filters.js"></script>
<script src="js/directives.js"></script>
</body>
</html>
Here is the service.js code
angular.module('myApp.services', []).
value('version', '0.1')
.value('author','Jay');
And the directive.js code
angular.module('myApp.directives', []).
directive('appVersion', ['version', function(version) {
return function(scope, elm, attrs) {
elm.text(version);
};
}])
.directive('appAuthor', ['author', function(author) {
return function(scope, elm, attrs){
elm.text(author);
};
}]);
The above code worked completely worked fine and displayed version and author configured in service.js
The moment i modify my controller.js to include a new controller as below it stops working and nor the version nor the author is displayed.
The modified controller code is as below
function MyCtrl1() {}
MyCtrl1.$inject = [];
function MyCtrl2() {
}
MyCtrl2.$inject = [];
angular.module('myApp', ['ui.bootstrap']);
var TabsDemoCtrl = function ($scope) {
$scope.panes = [
{ title:"Dynamic Title 1", content:"Dynamic content 1" },
{ title:"Dynamic Title 2", content:"Dynamic content 2" }
];
};
TabsDemoCtrl.$inject = ['$scope'];
Any pointers why this thing is not working.
Looks like your problem is the redeclaration of myApp here:
angular.module('myApp', ['ui.bootstrap']);
I was able to reproduce your problem when I had
angular.module('myApp', ['myApp.services', 'myApp.directives']);
angular.module('myApp', ['ui.bootstrap']);
Switching it to
angular.module('myApp', ['myApp.services', 'myApp.directives', 'ui.bootstrap']);
made everything work again.
