AngularJS - Name of my ng-controller can't be found - javascript

I'm new at AngularJS, started 2 days ago, but I can't resolve this problem.
The JS Console Error here
It seems that my directive ng-controller can't find my controller.
Here is my code :
<section class="index" ng-app="indexApp" ng-controller="cRegister">
<form>
<input type="text" ng-model="username" />
<input type="password" ng-model="password" />
<input type="submit" ng-click="" />
</form>
<script>
var app = angular.module('indexApp', [])
app.controller('cRegister', ['$scope', function() {
console.log('controller: true');
}]);
</script>
</section>
(This is a part of the main page, that I displayed with ng-view) :
<html ng-app="web">
<head>
<title>AngularJS, tries</title>
<meta charset="utf-8">
</head>
<body>
<div ng-view></div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.2/angular.min.js"></script>
<script src="https://code.angularjs.org/1.6.2/angular-route.min.js"></script>
<script>
var app = angular.module('web', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'partials/index.php'
})
.otherwise({
redirectTo: '/'
})
});
</script>
</body>
</html>
Hope someone could help me, thank you ! :D

you cannot have two ng-app directive in one html.
remove the inner one and add that controller to the first ng-app

AngularJS controller only working on first view

I am having some problems running my first AngularJS app. When I run my app all objects on my index are displayed properly. When I click on my hyperlink to move to view-2 all objects are displayed on HTML like plain text {{object.property}} What am I doing wrong?
This is my index.html:
<DOCTYPE html>
<html ng-app="tutorialApp">
<head>
<meta charset="UTF-8">
<title> Tutorial App</title>
<script src="lib/angular.min.js"></script>
<script src="lib/angular-route.min.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers/MyController.js"></script>
</head>
<body>
<div ng-view></div>
</body>
</html>
</DOCTYPE>
this is my app.js:
var app = angular.module('tutorialApp', ["ngRoute", "MyControllerModule"])
app.config(function ($routeProvider){
$routeProvider
.when("/", {
controller: "MyController",
templateUrl: "views/one.html"
})
.when("/two", {
controller: "ControllerTwo",
templateUrl: "views/two.html"
})
.otherwise({
redirectTo: "/"
});
});
this is my MyController.js:
angular.module("MyControllerModule", [])
.controller("MyController", ["$scope", function($scope){
$scope.myFirstObject = {};
$scope.myFirstObject.title = "Main Page";
$scope.myFirstObject.subTitle = "Sub Title";
$scope.myFirstObject.bindOutput = 13;
$scope.myFirstObject.firstname = "Wheelchair";
$scope.myFirstObject.lastname = "Terminator";
$scope.timesTwo = function(){
$scope.myFirstObject.bindOutput *= 2;
}
}])
.directive("myFirstDirective", function(){
return {
restrict: "E",
template: "<div>Hello how are you?</div>"
}
})
.controller("ControllerTwo", ["$scope", function($scope) {
$scope.testObject = {};
$scope.testObject.doSomething = "TEST TEST TEST TEST TEST!";
}
]);
This is my /views/one.html:
<h1>{{myFirstObject.title}}</h1>
<h2>{{myFirstObject.subTitle}}</h2>
<p>Number: {{2 + 2}}</p>
<p>String: {{myFirstObject.firstname + " " + myFirstObject.lastname}}</p>
<p><b>Multiply a number by two: {{myFirstObject.bindOutput | currency}}</b></p>
<button ng-click="timesTwo()">CLICK TO MULTIPLY</button><br>
<br>
<label>First Name:</label>
<input ng-model="myFirstObject.firstname">
<br>
<label>Last Name:</label>
<input ng-model="myFirstObject.lastname">
<br>
CLICK HERE FOR SECOND VIEW
<br>
<br>
<br>
<my-first-directive></my-first-directive>
this is my /views/two.html
<h1>Second View</h1>
<h2>this is the second view...</h2>
<br>
<br>
<p>Call object string: {{testObject.doSomething}}</p>
Change the href to route. Not html page.
CLICK HERE FOR SECOND VIEW
This should be
CLICK HERE FOR SECOND VIEW
As you did in the question, that calls the new html page to load into the browser. Not template of angular app. So, all the unknown stuff like {{object.property}} happens.
Use,
CLICK HERE FOR SECOND VIEW
Observe, href="#two"
<h1>{{myFirstObject.title}}</h1>
<h2>{{myFirstObject.subTitle}}</h2>
<p>Number: {{2 + 2}}</p>
<p>String: {{myFirstObject.firstname + " " + myFirstObject.lastname}}</p>
<p><b>Multiply a number by two: {{myFirstObject.bindOutput | currency}}</b></p>
<button ng-click="timesTwo()">CLICK TO MULTIPLY</button><br>
<br>
<label>First Name:</label>
<input ng-model="myFirstObject.firstname">
<br>
<label>Last Name:</label>
<input ng-model="myFirstObject.lastname">
<br>
CLICK HERE FOR SECOND VIEW
<br>
<br>
<br>
<my-first-directive></my-first-directive>

EDIT:
You seems to have issue with # url's
Solution:
HTML5 Mode
Configuration:
$routeProvider
.when('/two', {
templateUrl: 'views/two.html',
});
$locationProvider
.html5Mode(true);
You should set the base in HTML-file
<html>
<head>
<base href="/">
</head>
</html>
In this mode you can use links without the # in HTML files

example:
http://test.com/base/two

How create routes in AngularJS + JavaScript?

I'm creating a website and I'm using JavaScript + AngularJS, presently I create the routes for the application, but it always returns 404 not found on the server, I've tried several examples of the internet but none of them worked, here's an example of my code, remembering that The html pages are inside the WebContent:
<html ng-app="angularRoutingApp">
<head>
<title>Home</title>
<meta charset="utf-8">
</head>
<body>
<div>
index <br> home
</div>
<div ng-view></div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.3/angular-route.js"></script>
<script>
var angularRoutingApp = angular.module('angularRoutingApp', ['ngRoute']);
angularRoutingApp.config(function($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider
.when("/index", {
template: "/index.html"
})
.otherwise({
redirectTo: '/home.html'
});
});
</script>
</body>
</html>
you forgot the ng-view directive.
also,
the href need to be with a hash prefix - or using the Link directive.
the redirectTo key need to provide a view [name/address] & not a
template
if you want to use template files & not inline code use the templateUrl key
you can see an example of your code here: http://codepen.io/AceDesigns/pen/ZLXLKa
<html ng-app="angularRoutingApp">
<head>
<title>Home</title>
<meta charset="utf-8">
</head>
<body>
<div>
index<br>
home
</div>
<div class="">
<ng-view></ng-view>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.3/angular-route.js"></script>
<script>
var angularRoutingApp = angular.module('angularRoutingApp', ['ngRoute']);
angularRoutingApp.config(function($routeProvider){
$routeProvider
.when("/index", {template:"<div>INDEX VIEW</div>"})
.when("/home", {template:"<div>HOME VIEW</div>"})
.when("/tempFile", {templateUrl: "views/temp_file.html"})
.otherwise({redirectTo: '/home'});
});
</script>
</body>
</html>

AngularJS, controller is not a function, got undefined

Making a very simple application in angular, and everytime I try to do this I run into this problem and never know how to solve it.
App.js is this:
angular.module('Euclid',
['ui.bootstrap',
'ngRoute'])
.controller('mainController', function($scope){
})
.config(['$routeProvider', function($routeProvider){
$routeProvider.
when('/', {
templateUrl: 'views/home.html',
controller: 'HomeController',
controllerAs: 'homeCtrl'
});
}]);
Just some basic routing, nothing in the controller.
Now, that 'HomeController' is set up like this:
var HomeController = function($scope){
var self = this;
// code here
};
angular.module('Euclid').controller('HomeController', HomeController);
And my index.html is set up like so:
<html lang="en" ng-app="Euclid">
<body ng-controller="mainController" ng-cloak>
<script src="node_modules/angular/angular.js"></script>
<script src="app.js"></script>
<div class="container">
<div ng-view></div>
</div>
</body>
</html>
The error in all it's glory is "Argument 'HomeController' is not a function, got undefined". I can not for the life of me figure out where it is getting undefined.
I created a plunker to make things more clear . https://plnkr.co/edit/dL1DPa50mdZtmaJCwcIO?p=preview
As far as I can Understand ,there is no error other than missing some script files.
<html lang="en" ng-app="Euclid">
<body ng-controller="mainController" ng-cloak>
<script src="node_modules/angular/angular.js"></script>
<script src="../angular-route.js"></script> //missing
<script src="/ui-bootstrap-tpls-2.1.2.js"></script> //missing
<script src="app.js"></script>
<div class="container">
<div ng-view></div>
</div>
</body>
</html>
As Phil said ,it is clear that the reason for the
error is the missing of angular-router and angular-bootstrap.

Angular js input models not accessible inside controller

I am using this code to view and add peoples in an array.
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<body>
<h1>People</h1>
<div ng-controller="Ctrl">
<div ng-view></div>
</div>
<script src="angular.min.js"></script>
<script src="angular-route.min.js"></script>
<script src="controller.js"></script>
</body>
</html>
add.html
<h1>Add</h1>
<input type="text" ng-model="new_name" placeholder="Name">
<br />
<input type="text" ng-model="new_age" placeholder="Age">
<br />
<button ng-click="add()">Add</button>
<hr />
Back
controller.js
var app = angular.module('myApp', ['ngRoute']);
app.config(function ($routeProvider){
$routeProvider
.when('/',{
templateUrl: 'list.html'
})
.when('/add',{
templateUrl: 'add.html',
});
});
app.controller('Ctrl', function($scope) {
$scope.people = [{'name':'Alex', 'age':25}, {'name':'Dan', 'age': 25}];
$scope.add = function(){
$scope.people.push({'name':$scope.new_name, 'age':$scope.new_age});
$location.path("/");
};
});
The problem is, I am not getting data from ng-model="new_name" into the controller method $scope.add = function(). After pressing add button only blank strings gets pushed into array. However the model and controller working perfectly without routing and ng-view directive. I think its scope related problem. Can any body help me in this.
Thanks.
Because you should specify the controller for each view. So try doing this:
app.config(function ($routeProvider){
$routeProvider
.when('/',{
templateUrl: 'list.html',
controller: 'Ctrl'
})
.when('/add',{
templateUrl: 'add.html',
controller: 'Ctrl'
});
});
A better solution would be to have a separate controller for each view. Also, have a look at the $routeProvider documentation.
Just delete <div ng-controller="Ctrl"> from index.html and add a controller attribute for your route.
controller.js
var app = angular.module('myApp', ['ngRoute']);
app.config(function ($routeProvider){
$routeProvider
.when('/',{
templateUrl: 'list.html'
})
.when('/add',{
templateUrl: 'add.html',
controller: 'Ctrl'
});
});
app.controller('Ctrl', function($location,$scope) {
$scope.people = [{'name':'Alex', 'age':25}, {'name':'Dan', 'age': 25}];
$scope.add = function(){
$scope.people.push({'name':$scope.new_name, 'age':$scope.new_age});
$location.path("/");
};
});
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<body>
<h1>People</h1>
<div ng-view></div>
<script src="angular.min.js"></script>
<script src="angular-route.min.js"></script>
<script src="controller.js"></script>
</body>
</html>
first you have to wrap your inputs with <form> tag with name='' attribute.
Next step is to give name='' attributes for each <input> tag. Look:
<form name='myLoginForm'>
<input name='nick' ng-model='loginFormModel.nick'>
<input name='password' ng-model='loginFormModel.password'>
</form>
In controller:
app.controller('Ctrl', function($location,$scope) {
$scope.loginFormModel = {}; //now you have whole values from view in this variable, for example nick is available in $scope.loginFormModel.nick
});

ng-click event doesn't seem to fire in simple Angular app

I'm learning Angular through a YouTube tutorial series. In the tutorial, you create username and password inputs, and then you use a controller and ngRoute to bring up a dashboard.html page when successful credentials are used. The problem is that when clicking the button, nothing happens, whether the proper credentials are entered or not. Everything is working on the tutorial, and I have triple checked the code thoroughly, and mine looks just like the code in the tutorial. I'm sure I must be missing something though.
What I think:
There is an issue with the click event firing, so maybe there is an issue with how I am calling the function?
The tutorial uses an older angular version (1.3.14), and maybe things have changed? I'm using 1.4.9, but I looked up the api data for the ng-click directive, and all seems well. I also tried using the older version to no avail.
I'm doing something wrong with ngRoute, potentially $scope misuse?
I am inserting all of the code below. Thanks for taking a look!

dashboard.html
Welcome User.
Your form needs to be inside the div with ng-controller
<div ng-controller="loginCtrl">
<form action="/" id="myLogin">
Username: <input type="text" id="username" ng-model="username"><br>
Password: <input type="password" id="password" ng-model="password"><br>
<button type="button" ng-click="submit()">Login</button>
</form>
</div>
Otherwise it won't have access to the submit() function.
