Routing is not working with AngularJS - angularjs

As a part of learning process, I am roaming around angular js routing concepts. For this, I created one inner folder inside app with two sample test html pages ..
When i run the app it should load first page from that folder but it does not not happening .. I am not sure where i have done wrong in this code...
I am getting error like this 'angular.js:4640Uncaught Error: [$injector:modulerr]'
Below is my controller code
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'Pages/main.html',
controller: 'mainController'
})
.when('/second', {
templateUrl: 'Pages/second.html',
controller: 'secondController'
})
});
myApp.controller('mainController', ['$scope','$log', function($scope,$log) {
}]);
myApp.controller('secondController', ['$scope','$log', function($scope,$log) {
}]);
and html code goes here

Would any one please help on this query,
many thanks in advance..

Things seem to be working fine for me. See the working example below:
(Just change the href of Home link to #/)
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'Pages/main.html',
controller: 'mainController'
})
.when('/second', {
templateUrl: 'Pages/second.html',
controller: 'secondController'
})
});
myApp.controller('mainController', ['$scope', '$log',
function($scope, $log) {}
]);
myApp.controller('secondController', ['$scope', '$log',
function($scope, $log) {}
]);

Edit
Don't directly serve your Angular code using file:/// protocol. It will not be able to make request to load resources. Use any simple lightweight servers, for example:
Python Simple server for Linux based platforms (python -m SimpleHTTPServer)
Mongoose for Windows

replace:
<li><i class="fa fa-home"></i>Home</li>
with
<li><i class="fa fa-home"></i>Home</li>
and it should work fine. i checked.
That error means angular could not find the module you're referring to. is your script able to connect to internet and can you make sure the angular cdn is not blocked by your firewall?
you could try to download the angular-route file and reference in your html and see if it works.

AngularJS 1.0 routes not working

I am trying an application with AngularJS 1.0 but I am facing issues with routing. The route is not working at all. I can't see my templates being displayed inside ng-view. My code is as shown below.
package.json
"main": "server.js",
"dependencies": {
"angular": "^1.4.3",
"angular-route": "1.6.10",
"body-parser": "latest",
"ejs": "latest",

}

'use strict';
var app = angular.module('application', ["ngRoute"]);
app.config(function($routeProvider){
$routeProvider

templateUrl: 'client/index.html'
})
.when('/vault', {
templateUrl: 'client/vault.html'
})
.when('/store', {
templateUrl: 'client/store.html'

There are two more pages for store and about with only one tag in them.
I should be able to see the changes in the view part i.e. 'This is About page' but it is not being displayed.
I am referring to this URL
Any help would be appriciated.
Update-1
Added angular-route package but still not working.
Getting following error:
" Error: [$injector:modulerr] http://errors.angularjs.org/1.4.3/$injector/modulerr?p0=application&p1=%5B%24injector%3Amodulerr%5D%20http%3A%2F%2Ferrors.angularjs.org%2F1.4.3%2F%24injector%2Fmodulerr%3Fp0%3DngRoute%26p1"
Update-2
Entire console output, which shows some error but don't understand a bit of it. It has several warnings as well.
https://pastebin.com/j06ku3yG
Update-3
I didn't added the minified js files for angular-route in to my html and that was the reason I was getting issues. Further more the existing angular script in html page also had version mismatch.
I also corrected some issues with routes after this I faced recursion related issues (could see multiple pages within the same page) Had to make changes to routs.
Thank you all for helping :)
I have modified your code a bit to give you a basic working demo of your app. The routing required an angular-route.js script for 1.2+ AngularJS versions. For both scripts their versions must match. I decided to use 1.6.5. I also replaced bootstrap and jquery with ui.bootstrap - angularjs version.
Here is a working demo:
/* Use `ui.bootstrap` module instead of jQuery + Bootstrap */
var app = angular.module('application', ["ngRoute", "ui.bootstrap"]);
app.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'client/index.html'
})
.when('/about', {
templateUrl: 'client/about.html'
})
.when('/store', {
templateUrl: 'client/store.html'
})
});
app.controller('appController', function($scope, $location) {
$scope.isActive = function(path) {
return path === $location.path();
}
});

First, you still needs to link the NgRoute from the angular-route.js.
Secondly, to link templates use href="#!store" instead of href="#store"
Here's a working example using angularjs 1.6.9
'use strict';
var app = angular.module('application', ["ngRoute"]);
app.config(function($routeProvider){
$routeProvider
.when('/', {
templateUrl: 'home.html'
})
.when('/store', {
templateUrl: 'store.html'
})
.when('/about', {
templateUrl: 'about.html'
})
});

EDIT: actually, if I download this demo the thing wont work...

Your references for angular and bootstrap are not correct
Angularjs

Bootstrap
<link rel="stylesheet" href="https://netdna.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" />
You need to correct you urls like this
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'pages/main.html',
controller: 'mainController'
})
.when('/second', {
templateUrl: 'pages/second.html',
controller: 'secondController'
})
.when('/second/:num', {
templateUrl: 'pages/second.html',
controller: 'secondController'
})
});
myApp.controller('mainController', ['$scope', '$log', function($scope, $log) {
$scope.name = 'Main';
}]);
myApp.controller('secondController', ['$scope', '$log', '$routeParams', function($scope, $log, $routeParams) {
$scope.num = $routeParams.num || 1;
}]);

</ul>

</header>
<div class="container">
<div ng-view></div>
</div>

</html>
Also you need to add a page for the view on the following path in project pages/main.html
You need to use your application throught the localhost like this:
Just mount your project on HTTP server.
$> sudo npm -g live-server
$> cd path/to/root/dir/project
$> live-server
EDIT: and eventually, include every time your scripts at bottom of body:
<body>
.....
.....
.....
<script src="//code.angularjs.org/1.3.0-rc.1/angular.min.js"></script>
<script src="//code.angularjs.org/1.3.0-rc.1/angular-route.min.js"></script>

AngularJS Route does not loading view

My project structure is looks like this:
I tried to make a single page application using this image. When index.html page will launch it will by default load registration.html in ng-view. But when index.html loads it does not load the registration.html as ng-view as expected.
And my files for index.html,main.css and mainAppRouter.js are below:
//mainAppRouter.js
(function () {
var myModule = angular.module('studentInfo', ['ngRoute']);
myModule.config(function ($routeProvider) {
$routeProvider
.when('/registration', {
templateUrl : '../views/registration.html',
controller: 'regController'
})
.otherwise({
redirectTo: '/registration'
});
console.log("checking");
});
myModule.controller('regController', function ($scope) {
$scope.message = 'This is Add new order screen';
console.log("checking");
});
});
/*man.css*/
.studentInfo{
margin-top: 100px;
}
.navbar{
padding: 1em;
}
.navbar-brand {
padding:0;
}

<h1>Student Info</h1>
</div>
<div ng-view></div>
</div>
</body>
</html>
All my codes are in this github repo
What should i do to correct my problem?
I think the problem is because you have not specified any controller for your ng-view and also you have to set your base URL correctly.
$routeProvider
.when('/registration', {
templateUrl :'http://localhost/StudentInfo/app/views/registration.html',
controller: 'regController'
})
And remove the controller tag from HTML.Your controller tag was outside the scope of ng-view.
<div class="container">
<div class="col-md-4 col-md-offset-4" >
<h1>Student Info</h1>
</div>
<div ng-view></div>
</div>
And there is a syntax error in your controller as well
myModule.controller('regController', function ($scope){
$scope.message = 'This is Add new order screen';
})
UPDATED ANSWER: Another reason why this does not work is that you are running your example off the file system (using the file:// protocol) and many browsers (Chrome, Opera) restricts XHR calls when using the file:// protocol. AngularJS templates are downloaded via XHR and this, combined with the usage of the file:// protocol results in the error you are getting.

ngRoute not working as expected

I am trying to learn about routes in in angular and I am having some trouble getting the proper text to display. It seems that everything is working without errors when I run my page however, the view is not changing from main.html to second.html when I click on the link.
Here are some snips of my code...
<html ng-app="myApp">

myApp.controller('secondController', ["$scope", "$log", "$location", function($scope, $log, $location) {
}]);
try ui-router instead of ngRoute
I am using it in a lot of projects and its working very good
doc: https://github.com/angular-ui/ui-router
At first line in your index.html, you're opening a <html> tag, but you're closing with a </head> one, plus, I'd recommand placing your ng-app="myApp" in the opening <body> tag, this way :
<head>
<!-- everything you need -->
</head>
<body ng-app="myApp">
<!-- and stuff -->
</body>
If this doesn't change anything after correcting these errors, I really don't know what's the problem, everything looks ok.

Navigation to new html page using Angular.js

I am working in angular.js. Using ng-view navigate in body section. If i need to navigate to a new html page. How we can achieve in angular.js. Is there any angular.js directives in angular.js.
Thanks in Advance,
You should go through following things for routing:
Angular ui-route
Angular ngRoute
Angular-UI-Router is more powerful directive than ngRoute. Following code is what i had tried sometimes before. hope it will also help you.
app.js
var app = angular.module('app', ['ui.router']); //Inject `ui.router` directive inside your `app` module
app.config(['$urlRouterProvider', '$stateProvider', function ($urlRouterProvider, $stateProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('home', {
url: '/',
templateUrl: 'templates/home.html',
})
.state('about', {
url: '/about',
templateUrl: 'templates/about.html'
})
}]);
