Assume i have a login page, after entering username and password fileds while click on submit button it needs to validate and if both username and password is correct it needs to go home page. Home page content needs to display. Here i am posting code. In Browser url is changing but content is not changing.

Hello I am from Home page
test.js
var applog = angular.module('myApp',['ngRoute']);
applog.config([ '$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.when('/home', {
templateUrl : 'home.html',
controller : 'HomeController'
}).otherwise({
redirectTo : 'index.html'
});
//$locationProvider.html5Mode(true); //Remove the '#' from URL.
}
]);
applog.controller("LoginController", function($scope, $location) {
$scope.login = function() {
var username = $scope.user.name;
var password = $scope.user.password;
if (username == "admin" && password == "admin") {
$location.path("/home" );
} else {
alert('invalid username and password');
}
};
});
applog.controller("HomeController", function($scope, $location) {
});

If you want to navigate to different pages in your application, but you also want the application to be a SPA (Single Page Application), with no page reloading, you can use the ngRoute module. The ngRoute module routes your application to different pages without reloading the entire application.
Routing in AngularJS is used when the user wants to navigate to different pages in an application but still wants it to be a single page application. AngularJS routes enable the user to create different URLs for different content in an application.
In HTML5 mode, the $location service getters and setters interact with the browser URL address through the HTML5 history API. This allows for use of regular URL path and search segments, instead of their hashbang equivalents.
To change path URL with AngularJS, $location. path() is passed the new URL as a parameter, and the page is automatically reloaded. This means that if you ever make a change to the URL in an Angular application, then the partial and controller will be reloaded automatically.
As @dfsq said you need an ng-view for placing there your new view. Of course if you add your ng-view in the index you will see the content of the index and of home. The solution here is creating two partial views, one for the log in authentication and the other for home. The index file should contain only the ng-view and those elements you want to keep constant in your whole app (menu, footer...)
Here is the code for what I'm saying: index.html
<html ng-app='myApp'>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"/>
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"></script>
<script
src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular-route.js"></script>
<script src='test.js' type="text/javascript"></script>
</head>
<body >
<div ng-view></div>
<script src='test.js' type="text/javascript"></script>
</body>
</html>
Your new route configuration
applog.config([ '$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.when('/home', {
templateUrl : 'home.html',
controller : 'HomeController'
})
$routeProvider.when('/', {
templateUrl : 'auth.html',
controller : 'LoginController'
}).otherwise({
redirectTo : 'index.html'
});
//$locationProvider.html5Mode(true); //Remove the '#' from URL.
}
]);
and put your login code inside the auth.html file
<div id='content' ng-controller='LoginController'>
<div class="container">
<form class="form-signin" role="form" ng-submit="login()">
<h3 class="form-signin-heading">Login Form</h3>
<span><b>Username :</b> <input type="username"
class="form-control" ng-model="user.name" required> </span> </br>
</br> <span><b>Password :</b> <input type="password"
class="form-control" ng-model="user.password" required> </span>
<br><br>
<button class="btn btn-lg btn-primary btn-block" type="submit">
<b>Sign in</b>
</button>
</form>
</div>
<!-- /container -->
</div>
Have in mind that if you place the test.js script in index it will be in the whole app.
Hope it helps
