ui-router not replacing ui-view in index.html - javascript

I have set up a basic AngularJS app in VS and cannot get the ui-router functionality working. I have looked at videos, blogs, SO answers and as far as I can tell I am doing everything right, although, I am brand new to web development.
First, here is the solution structure:
and the code...
index.html:
<!DOCTYPE html>
<html>
<head>
<title>Example</title>
<meta charset="utf-8" />
</head>
<body ng-app="app">
<div ui-view></div>
<script src="bower_components/angular/angular.js"></script>
<script src="app/app.js"></script>
<script src="bower_components/angular-ui-router/release/angular-ui-router.js"></script>
</body>
</html>
app.js:
(function () {
'use strict';
angular.module('app', ['ui.router']);
})();
app.states.js:
(function () {
'use strict';
angular.module('app')
.config(function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('home', {
url: '/',
templateUrl: 'templates/test.html',
controller: 'testCtrl',
controllerAs: 'vm'
})
});
})();
test.html:
<div>
<p>TEST PAGE</p>
</div>
testCtrl.js:
(function () {
'use strict';
angular.module('app')
.controller('testCtrl', testCtrl);
testCtrl.$inject = ['$state'];
function testCtrl($state) {
var vm = this;
var userAuthenticated = false;
init();
function init() {
$state.go('home');
};
};
})();
Can anyone see anywhere I have made a mistake?

There is a working example
I would say, that I miss these lines in your index.html
...
<script src="app/app.states.js"></script>
<script src="templates/testCtrl.js"></script>
That will loade the crucial state definition, and related controller. Check it in action here

Hey, this is part from application when I use ngRoute and dynamically add home.html, but I think I have wrong app.js or home.controller.js beacuse when I add external file home.js (when is ng-controller=""RedCtrl. I get error [$controller:ctrlreg] RedCtrl is not register. Have you ideas why? I am new in Angular and I think the main reason is lack of my knowledge.
You are overwriting app module in home.js thus getting the error
Use
var app = angular.module('app'); //Get previously defined module
instead of
var app = angular.module('app', []); //It declares new module
You also need to change the sequence of JavaScript files
<script src="app.js"></script>
<script src="home.js"></script>

Hashbang defaulting in angular application

Do the newest versions of angular/angular-route 1.6.1 use hashbang by default? Take this piece of code for example, I have to use #! when linking to partials because #/ or #/partial2 does not work. I thought that you'd have to set a hash prefix but it looks like it's defaulting to that behavior:
<!DOCTYPE html>
<html ng-app='myApp'>
<head>
<title></title>
<script src="bower_components/angular/angular.min.js"></script>
<script src="bower_components/angular-route/angular-route.js"</script>
<script>
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function ($routeProvider) {
$routeProvider
.when('/',{
templateUrl: 'partials/view1.html',
})
.when('/partial2',{
templateUrl: 'partials/view2.html'
})
.otherwise({
redirectTo: '/'
});
});
myApp.controller('view1Controller', function ($scope) {
$scope.sports = ['golf', 'basketball', 'hockey', 'tennis', 'football'];
});
myApp.controller('view2Controller', function ($scope) {
$scope.message = 'We are using another controller';
});
</script>
</head>
<body>
<div ng-app='myApp'>
Partial 1 | Partial 2
<div ng-view="">
</div>
</div>
</body>
</html>
Starting angular 1.6.0, #!/ becomes defaults in routes. I basically worked down versions until #/ worked, which was 1.5.11.

cannot pass parameters via angular service between 2 html file

I have 2 html file and I want to pass parameters via angular service between them.
these are the files I have:
index.html
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/style.css">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body>
<script type="text/javascript" src="services.js"></script>
<div ng-app="myApp" ng-controller="myCtrl2">
</div>
enter here
<script>
var app=angular.module("myApp");
app.controller("myCtrl2", ['$scope','$location', 'myService',
function($scope, $location, myService) {
myService.set("world");
}]);
</script>
</body>
</html>
enter2.html
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/style.css">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
</head>
<body>
<script type="text/javascript" src="services.js"></script>
<div ng-app="myApp" ng-controller="myCtrl3">
hello {{x}}
</div><script type="text/javascript">
var app=angular.module("myApp");
app.controller("myCtrl3", ['$scope','$location', 'myService',
function($scope, $location, myService) {
$scope.x=myService.get();
}]);
</script>
</body>
</html>
services.js
var app=angular.module("myApp", []);
app.factory('myService', function() {
var savedData = {}
function set(data) {
savedData = data;
}
function get() {
return savedData;
}
return {
set: set,
get: get
}
});
why can't I get "hello world" in enter2.html, but instead get "hello" (x is not found by service)...?
When you go from index.html to enter2.html the whole page loads from scratch. For the data that you are expecting to stay in the browser, you might need to use advanced angular concepts such as loading just a part of the page using ng-view.
If that's something you have already overruled, saving the data in the service somewhere (may be the browser session) before unloading (window.onunload event) the page and then loading it back from there when the service loads (window.onload event) could also work.
Here is a working example based on your code.
I kept your index.html and added ui-view to have a single page application. The app uses 'ui.router'.
In the myCtrl2 I saved the data in the service, and call it back from myCtrl3:
.controller('myCtrl2', ['$scope', 'myService', function($scope, myService) {
console.log('myCtrl2');
myService.set('world');
}])
.controller('myCtrl3', ['myService', function(myService) {
console.log('myCtrl3');
var vm = this;
vm.x = myService.get();
}])
To keep things simple, I have one Javascript file:
angular.module('myApp', ['ui.router'])
.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('home', {
url: '/home',
templateUrl: 'index.html',
controller: 'myCtrl2',
controllerAs: 'vm'
})
.state('enter2', {
url: '/enter2',
templateUrl: 'enter2.html',
controller: 'myCtrl3',
controllerAs: 'vm'
});
})
.factory('myService', function() {
var savedData = {}
function set(data) {
savedData = data;
}
function get() {
return savedData;
}
return {
set: set,
get: get
}
})
.controller('myCtrl2', ['$scope', 'myService', function($scope, myService) {
console.log('myCtrl2');
myService.set('world');
}])
.controller('myCtrl3', ['myService', function(myService) {
console.log('myCtrl3');
var vm = this;
vm.x = myService.get();
}])
I also uses the var vm=this and ControllerAs as often recommended to avoid $scope issues.
index.html looks like below... pleaes note the ui-sref instead of href:
<div ui-view="">
<a ui-sref="enter2">Enter here</a>
</div>
enter2.html is now just the div part and your content:
<div>
Hello {{ vm.x }}
</div>
Let us know if that helps.

AngularJS Routing Function is not working

My Angular Routing Function is not working - There is a page load, but without the 'home.html' file. This is my code:
Index.html
<html ng-app="App" class="no-js" lang="en" >
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular-route.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-cloak>
<div ng-controller="main">
<div ng-view></div>
</div>
</body>
</html>
app.js
(function () {
'use strict';
angular
.module('App', ['ngRoute'])
.controller('$routeProvider', router)
.controller('main', main);
function router($routeProvider) {
$routeProvider.
when('/', {
templateUrl: '_pages/home.html',
controller: 'main'
});
};
function main ($scope) {
console.log("done");
}
Angular $providers working just in config state.
Eg:
angular
.module('App', ['ngRoute'])
.config(['$routeProvider', router]);
function router($routeProvider) {
$routeProvider.
when('/', {
templateUrl: '_pages/home.html',
controller: 'main'
});
};
The route configuration is done in config and not controller. Change your code as below:
(function () {
'use strict';
angular
.module('App', ['ngRoute'])
.config(router)
.controller('main', main);
function router($routeProvider) {
$routeProvider.
when('/', {
templateUrl: '_pages/home.html',
controller: 'main'
});
};
function main ($scope) {
console.log("done");
}
});

Angular states point to correct controller but not html

I am just setting up a simple Angular app as I've done countless times. I added a home state and a separate state for a note taking app, yet neither states are displaying/injecting the html partials into the ui-view. I think it might be an issue with my ui-router setup, but I cannot find the issue. I console log from my controllers and they trigger correctly, so the states are clearly pointing to the right controllers.
Index
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>title</title>
<script src="bower_components/angular/angular.js"></script>
<script src="node_modules/angular-ui-router/release/angular-ui-router.js"></script>
<script src="app.js"></script>
<script src="factory.js"></script>
<script src="config.js"></script>
</head>
<body ng-app="myApp">
<ui-view></ui-view>
</body>
</html>
config
app.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/home',
templateURL: './home.html',
controller: 'homeCtrl'
})
.state('list', {
url: '/list',
templateURL: '/list.html',
controller: 'listCtrl'
})
$urlRouterProvider.otherwise('/home');
});
app.js
'use strict';
var app = angular.module('myApp', ['ui.router']);
app.controller('listCtrl', function($scope, myFactory) {
console.log("list working!");
$scope.items = myFactory.items
$scope.addItem = function() {
$scope.items.unshift($scope.newItem);
$scope.newItem = "";
}
})
app.controller('homeCtrl', function($scope) {
console.log("home working!");
$scope.test = 'test'
})
My home state should load a partial containing:
<div>
<h1>Welcome!</h1>
</div>
Plunker
http://plnkr.co/edit/ngHYDtx0VBe2YPlBeJ3t?p=preview
It has to be
templateUrl: './home.html',
Also, it is not desirable to use relative paths for templates, './home.html' and 'home.html' will be cached internally as two different templates.
