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">
<!-- load angular via CDN -->
<script src="https://code.angularjs.org/1.6.1/angular.min.js"></script>
<script src="https://code.angularjs.org/1.6.1/angular-route.min.js"></script>
<script src="app.js"></script>
</head>
<body>
<header>
<nav class="navbar navbar-default">
<div class="container">
<div class="navbar-header">
<a class="navbar-brand" >AngularJS</a>
</div>
<ul class="nav navbar-nav navbar-right">
<li><i class="fa fa-home"></i> Home</li>
<li><i></i>Second</li>
</ul>
</div>
</nav>
</header>
<div class="container">
<div ng-view></div>
</div>
</body>
main html contents:
<h1>This is main</h1>
second html contents:
<h1>This is second</h1>
app.js
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", "$log", "$location", function($scope, $log, $location) {
}]);
myApp.controller('secondController', ["$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.

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.
Index.html
<!DOCTYPE html>

app.controller('aboutController', function($scope){
$scope.message = "This is the about page and it looks awesome!";
});
app.controller('contactController', function($scope){
$scope.message = "This is the contact page!";
});
})();
One of the pages
<div class="jumbotron text-center">
<h1>Home Page</h1>
<p>{{ message }}</p>
</div>
i'm having this online course on AngularJS, which provides the code in folders, according to the lesson. This one is about routing and single page applications; similar demos and structures work on plunker (like this one ) but not in my machine...I don't understand why, can someone help me out?
EDIT: actually, if I download this demo the thing wont work...

Your references for angular and bootstrap are not correct
Angularjs
<script src="https://code.angularjs.org/1.3.0-rc.1/angular.min.js"></script>
<script src="https://code.angularjs.org/1.3.0-rc.1/angular-route.min.js"></script>
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;
}]);
<html lang="en-us" ng-app="myApp">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge">

<script src="app.js"></script>

<body>
<header>
<nav class="navbar navbar-default">
<div class="container">
<div class="navbar-header">
<a class="navbar-brand" href="/">AngularJS</a>
</div>
<ul class="nav navbar-nav navbar-right">

<li><i></i> Second</li>
</ul>
</div>
</nav>
</header>
<div class="container">
<div ng-view></div>
</div>
</body>
</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
$> live-server
EDIT: and eventually, include every time your scripts at bottom of body:
<body>
.....
.....
.....
<script src="//code.angularjs.org/1.3.0-rc.1/angular.min.js"></script>
<script src="//code.angularjs.org/1.3.0-rc.1/angular-route.min.js"></script>
<script src="app.js"></script>
</body>
I learn angularjs after a tutorial and I saw that you can remove # from the link. I did that but then my partials(from templateUrl) did't come in the page anymore.
Can someone please tell me where I'm wrong?
angular.module('myApp', ['ngRoute'])
.controller('mainController', ['$scope', '$location', '$log', function($scope, $location, $log) {
$log.info($location.path());
}])
.controller('secondController', ['$scope', '$location', '$log', function($scope, $location, $log) {
$log.info($location.path());
}])
.config(function($routeProvider, $locationProvider) {
// $routeProvider lets us specify routes
$routeProvider
.when('/', {
templateUrl: 'pages/main.html',
controller: 'mainController'
})
.when('/second', {
templateUrl: 'pages/second.html',
controller: 'secondController'
});
$locationProvider.html5Mode(true);
});

main.html:
<h1>This is Main.</h1>
second.html
<h1>This is second.</h1>
So in my browser I don't get main.html and second.html when I click on Home and Second. Why?
The UI Router github docs mentions:
When you have html5Mode enabled, the # character will no longer be used in your urls. The # symbol is useful because it requires no server side configuration. Without #, the url looks much nicer, but it also requires server side rewrites.
When you are trying to access your app in html5Mode (routes without any hash) then first of all you would need to remove the "#" from each one of your links (in this case the links are: Home, Second).
So...
"#" would just be "/"
"#/second" would be "/second"
After this, you would also need to enable server side URL Rewrites. Please checkout this link and configure your server as per the server that you are using.
Try to establish a .otherwise() at the end of $routerProvider that specifies a default route.
The templates main.html and second.html are defined correctly? The location is correct?
As a part of learning process, I am roaming around angular js routing concepts. For this, I created one inner folder inside app with two sample test html pages ..
When i run the app it should load first page from that folder but it does not not happening .. I am not sure where i have done wrong in this code...
I am getting error like this 'angular.js:4640Uncaught Error: [$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 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'
})
}]);
