AngularJS Controller $scope not displaying variable - angularjs

I am new to AngularJs.
In app.js I have the following
angular.module('module1', ['module2'])
.config(function($routeProvider) {
$routeProvider
.when('/',
{
controller: 'Controller1',
templateUrl: '/app/module/module1/partials/module1.html'
});
});
My module1 controller
angular.module('module1').controller('Controller1', function($scope) {
$scope.module1Name = "Module1";
});
In module2 folder I have Index.js
angular.module('module2', []).config(function($routeProvider) {
$routeProvider
.when('/test',
{
controller: 'Controller1',
templateUrl: '/app/module/module2/view/test.html'
});
});;
Module2 controller
angular.module('module2').controller('Controller1', function ($scope) {
$scope.module2Name = "Module2";
});
Here is my index.html
<html data-ng-app="module1">
<head>
<meta name="viewport" content="width=device-width" />
<title>Angular</title>
<script src="~/Scripts/angular.min.js"></script>
<script src="~/App/app.js"></script>
<script src="~/App/module/module2/index.js"></script>
<script src="~/App/module/module2/controller/Controller1.js"></script>
<script src="~/App/module/module1/controller/Controller1.js"></script>
</head>
<body>
<div data-ng-view=""></div>
</body>
</html>
and module1.html
<div>
f4b view {{module1Name}}
<br/>
<a data-ng-href="#/test">Test page</a>
</div>
and test.html
<div>
Test view {{module2Name}} <br/>
<a data-ng-href="#/">f4b page</a>
</div>
when I start the application the module1 name is displayed but when I click the link all I see is "Test view" without module2
{{module2Name}} is not displayed...
Can someone tell me what am I doing wrong?
Thank you

Angular's $injector can't disambiguate between controllers that use the same name. One workaround is to manually namespace them:
angular.module('module1').controller('mod1.Controller1',
...
angular.module('module2').controller('mod2.Controller1',

AngularJS ng-view not showing routed pages

The ng-view is not showing pages and routing doesn't seem to work but it is loading the angular-route.min.js in the browsers console/network.
The file structure is folders -> css, fonts, js, pages. there are 2 files in the root which are app.js and index.html and inside the pages folder are 2 more files which are the main.html and second.html which are supposed to be added to the ng-view parts but wont load.
When clicking on a link for the main.html content it comes back with http://127.0.0.1/main and completely ignores the /pages folder
**updated code, got the first page to load its content but the second one doesn't and there are no errors in the console so assumably I have the wrong href path?

myApp.controller('mainController', ['$scope', function($scope) {

myApp.controller('secondController', ['$scope', '$log', function($scope, $log) {
}]);
Use templateUrl instead of templateURL.
In your html use #/main.
Don't use tow ng-views
JS code
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function($routeProvider) {
$routeProvider
.when('/main', {
templateUrl: 'main.html',
controller: 'mainController'
})
.when('/second', {
templateUrl: 'second.html',
controller: 'secondController'
})
});
myApp.controller('mainController', ['$scope', function($scope) {
$scope.name = "world"
}]);
myApp.controller('secondController', ['$scope', '$log', function($scope, $log) {
}]);

Here is working plunker
EDIT
Please note I have used angular version 1.4.0. If you want to use angular 1.6.1 they have changed default hash-prefix used for $location hash-bang URLs it is now ('!') instead of ('')
So you need to add this in your config phase.
myApp.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix('');
}]);
now it will work with angular 1.6.1 as well
.when('/main', {
templateURL: 'pages/main.html',
controller: 'mainController'
})
or
use this url to access main page :
http://127.0.0.1/
It should work, as you have not set routing for main in config.

Angular view not loading

Im not sure where to place the partials folder holding the html views! I have placed it at the app root folder, in views and in public. Also tried removing the first trailing slash of the templateUrl but nothing. I also have tried(as view loading container):
<div ng-view></div>
<ng-view></ng-view>
<div data-ng-view></div>
<div ng-view=""></div>
<div ng-view="demoApp"></div>
This is just a learning example holding a module with 2 controllers and 2 views.
Here is the SPA(this page renders as rout '/' of a dancer(perl) project):
<!DOCTYPE html>
<html ng-app="demoApp">
<head>
<title><% title %></title>
<link rel="stylesheet" href="/customised_bootstrap/css/bootstrap.css">
<script src="/bower_components/underscore/underscore.js"></script>
<script src="/bower_components/backbone/backbone.js"></script>
<script src="/bower_components/angular/angular.js"></script>
<script src="/bower_components/angular-resource/angular-resource.js"></script>
<script src="/bower_components/angular-route/angular-route.js"></script>
<script src="/bower_components/ng-tasty/ng-tasty-tpls.js"></script>
<script>
//define a module
var demoApp = angular.module('demoApp', ['ngRoute']);
//define routes for our module(each route will have its set of views and controllers)
demoApp.config =(function ($routeProvider) {
$routeProvider
.when('/',
{
controller: 'simpleController1',
templateUrl: '/partials/testAlexView1.html'
})
.when('/testAlexView1',
{
controller: 'simpleController2',
templateUrl: '/partials/testAlexView1.html'
})
.when('/testAlexView2',
{
controller: 'simpleController2',
templateUrl: '/partials/testAlexView2.html'
})
.otherwise({redirectTo: '/partials/testAlexView1.html'});
});
//define a controller within our module 'demoApp'
demoApp.controller('simpleController1', function ($scope) {
$scope.customers = [
{name:'Boris', age:'18'},
{name:'Claudia', age:'28'},
{name:'Carlos', age:'39'},
{name:'Ben', age:'25'}
];
//var stuff ={};
});
demoApp.controller('simpleController2', function ($scope) {
$scope.customers = [
{name:'Alex', age:'18'},
{name:'Albert', age:'28'},
{name:'Anthony', age:'39'},
{name:'Loren', age:'25'}
];
});
</script>
</head>
<body>
<div>
<p>Main page of SPA test</p>
<div ng-view></div>
</div>
</body>
</html>
Here are the two identical views:
testAlexView1.html(testAlexView2.html is the same):
<div>
<input type="text" data-ng-model="name" /> {{ name }}
<br />
<ul>
<li data-ng-repeat="customer in customers | filter:name | orderBy:'age'">
{{customer.name}} - {{customer.age}}
</li>
</ul>
</div>
In the browser inspector, within the div where the view should load, all that appears is(both at root or root#/view.html):
<!-- ngView: -->
Batarang dosn't detect scopes nor modules neither. Thanks for any help!
There appears to be a typo in your config here:
demoApp.config =(function ($routeProvider) {
Instead try:
demoApp.config(function ($routeProvider) {

AngularJS routes and template loading

I'm trying to create a single page app with angularjs to which I'm very new. I've pieced together this code based on a number of tutorials, but it doesn't work and I'm not quite sure why. I'm not getting any errors that I can see. The intention is to have the home.html file load on the initial load. Then based on the routes, load in different templates.
script.js
angular.module("myApp", ['ngRoute']).config(['$routeProvider', function($routeProvider){
$routeProvider.when("/view", {
templateUrl: "/view.html",
controller: "ViewCtrl"
})
.otherwise({
templateUrl: "/home.html",
controller: "HomeCtrl"
});
}]);
angular.module("myApp").controller("ViewCtrl", ['$scope', function($scope){
$scope.message = "In the view";
}]);
angular.module("myApp").controller("HomeCtrl", ['$scope', function($scope){
$scope.message = "At home";
}]);
angular.element(document).ready(function(){
angular.bootstrap(document, ['myApp']);
})
index.html
<!DOCTYPE html>
<html>
<head>
<script data-require="angular.js#1.4.0-beta.4" data-semver="1.4.0-beta.4" src="https://code.angularjs.org/1.4.0-beta.4/angular.js"></script>

<div ng-controller="ViewCtrl">
{{message}}
</div>

Couple of mistakes in your code. Please look the below changes
1) Add ng-view directive for loading partial content
<div id="content" ng-app="myApp"></div>
should be
<div id="content" ng-app="myApp" ng-view></div>
2) Template url not starts with slash (/)
templateUrl: "/view.html",
templateUrl: "/home.html",
Should be
templateUrl: "view.html",
templateUrl: "home.html",
3) No need to bootstrap the app manually, ng-app automatically do this.
4) No need to mention the controller in router level if you mentioned in template (vice versa)

Data-Binding not working in view page - Angular.js

I have shown a simplified version of my problem below:
The directive 'name' is not understood when it is in the view 'loginView.html', however it works fine when It's in the main page 'index.html'
loginView.html
<p>Welcome : {{name}}</p>
<input type="text" data-ng-model="name"><br>
<button type="submit" data-ng-click="loginUser()">Login</button>
index.html
<!doctype html>
<html data-ng-app="vla">
<head>
<title>Video Learning application</title>
<link rel="stylesheet" type="text/css" href="css/style.css"/>
</head>
<body>
<div class = "navBar">
<div class = "leftButton"></div>
<div class = "title">VLA</div>
<div class = "rightButton"></div>
</div>
<div data-ng-view=""></div>
<script src="scripts/angular.js"></script>
<script src="scripts/angular-route.js"></script>
<script src="controllers/controllers.js"></script>
<script src="app.js"></script>
</body>
</html>
app.js
var app = angular.module('vla', ['ngRoute']);
app.config(function ($routeProvider){
$routeProvider
.when('/view1',
{
controller: 'controllers/controllers.js',
templateUrl: 'partials/loginView.html'
})
.otherwise({ redirectTo: '/view1' });
});
controller.js
app.controller('loginController', function ($scope)
{
$scope.loginUser = function () {
alert("test");
}
});
The {{name}} just prints itself out when in the view 'loginView', but works fine and prints he contents of the input field when placed into index.html.
I'm very new at this and would appreciate any help.
Thanks in advance
You should write controller name but not path in controller option of routeProvider:
$routeProvider
.when('/view1',
{
controller: 'loginController',
templateUrl: 'partials/loginView.html'
})
.otherwise({ redirectTo: '/view1' });
And attach file with controller (controllers/controllers.js) with tag <script>.
Just realised the problem was the ordering of the script declarations in the index.php page
The app reference should come before the controller:
<script src="app.js"></script>
<script src="controllers/controllers.js"></script>

AngularJS: Load view from Controller?

I'd like to understand how to load a view from a controller ?
Example, hypothetical:
myFile.html
<p>{{foo}}</p>
.controller("myCtrl", function(){
$scope.html = loadFileHere("My foo", "myFile.html");
console.log($scope.html);
});
I'd expect the output:
<p>My foo</p>
Is this possible to do ?
Thanks!
I am guessing you are talking about loading partials? You wouldn't really load a view with a controller, although MAYBE you could...I would use your routes to load a view. Your controller would return your scoped data to your partial view and then you would load it into an ng-view div or whatever. So for example...
in your app.js (or whatever you call it) assuming your myFile.html is in the same directory:
angular.
module('app', []).
config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/myFile', { templateUrl: 'myFile.html', controller: MyCtrl }).
otherwise({ redirectTo: '/' });
}]);
Then maybe in a controllers.js file:
function MyCtrl($scope) {
$scope.foo = "My foo";
}
And then in your myFile.html partial :
<p>{{foo}}</p>
And then your index.html file may look something like:
<!doctype html>
<html ng-app="app">
<head>
<script src="js/angular.min.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
</head>
<body>
<div ng-controller="MyCtrl">
<div class="container">
<div ng-view></div>
</div> <!-- /container -->
</div>
</body>
</html>
