I am learning how to implement routing in AngularJS. Everything else is working fine but the views are not getting updated when I click on the navigation.
How can I achieve the desired functionality in the application? I want the navigation to take us to the desired pages without refreshing the page and that's quite obvious.
Here is the code.

please tell me why it isn't loading partials.
I'm trying to do routing and inserting a partial templates into the layout HTML page when you click on a specific hyperlink such as Home, about or contact.
I checked in every line of code and I didn't find the source of problem for not loading partials. Routes are doing fine, it just isn't loading.
Here's my code:
index.html

I had changed the default hash-prefix from '!' to empty string '' in app.js cause I'm using angularjs 1.6
$locationProvider.hashPrefix('');
Remove ng-app from your body element. You already have it on the outer html element.
I use ui-router instead of ngRoute, but they are very similar. A couple of things.
You need to set Html5Mode, which means you need to inject $locationProvider into your config and then issue:
$locationProvider.html5Mode(true)
You should set the base href in the <head> section of your index.html with:
<base href="/" >
You might also want to try ng-href instead of href on your links.
My project structure is looks like this:
I tried to make a single page application using this image. When index.html page will launch it will by default load registration.html in ng-view. But when index.html loads it does not load the registration.html as ng-view as expected.
And my files for index.html,main.css and mainAppRouter.js are below:
//mainAppRouter.js
(function () {
var myModule = angular.module('studentInfo', ['ngRoute']);
myModule.config(function ($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.
For more details: Couldn't load template using templateUrl in Angularjs
I don't know why angular routing didn't work with me. I revised the code 10 times and I couldn't find the solution.
My index page is like -
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<title></title>
<meta charset="utf-8" />
<link href="Content/bootstrap.css" rel="stylesheet" />

<ng-view>
</ng-view>
<h3 style="font-size:small" class="text-center text-info">developed by Mr-Mohammed Elwany</h3>
</div>
</body>
</html>
and Javascript page like
/// <reference path="C:\Users\elwany\documents\visual studio 2015\Projects\spaapplication\spaapplication\scripts/angular.js" />
var myApp = angular.module("myApp", ['ngRoute']);
myApp.config(['$routeProvider',
function ($routeProvider) {
$routeProvider.
when('/add', {
templateUrl: 'Views/add.html',
controller:'addController'
}).
when('/edit', {
templateUrl: 'Views/edit.html',
controller: 'editController'
}).
when('/delete', {
templeteUrl: 'Views/delete.html',
controller: 'deleteController'
}).
when('/home', {
templateUrl: 'Views/home.html',
controller: 'homeController'
}).
otherwise({ redirectTo: '/home' });
}]);
myApp.controller("addController",function ($scope) {
$scope.message = "in Add view Controller";
});
myApp.controller("editController",function ($scope) {
$scope.message = "in edit view Controller";
});
myApp.controller("deleteController",function ($scope) {
$scope.message = "in delete view Controller";
});
myApp.controller("homeController",function ($scope) {
$scope.message = "in home view Controller";
});
I have 4 html pages in "Views" folder their name is "add","edit","delete","home" and they have the same content.
<div class="row jumbotron">
<h2>{{message}}</h2>
</div>
Please I want to know why it didn't work.
Actually your code is correct but Angular applications work properly on client server architecture.
Kindly Run your application using a local server. There is no need for any Tomcat server. You can easily download a Google Chrome Plugin "Web server for Chrome". here- https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb?hl=en

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.
I am working through the mean-machine tutorial and have come to a road block when using ng-view to inject pages into the main layout. I have configured the routes in app.routes.js, defined the controllers in app.js, as well as created the html files for each page. Both app.js and app.routes.js have been loaded into the index.html file. mainController is working fine, just not the ancillary controllers. Please see the code below. Any idea on what I am doing wrong?

Are you sure your templateURL properties have the right value? Try with public/views/pages/home.html or any full URL that shows up when you browse to your application in your browser.
See the documentation on the $routeProvider : https://docs.angularjs.org/api/ngRoute/provider/$routeProvider.
