I am trying to implement a navigation into a webpage using angularJS. The problem is that the route does not work at all. The browser console does not give any errors and the ng-view just does not show the templatesUrls.
route.js
var routeApp = angular.module('myApp', ['ngRoute']);
routeApp.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'partials/task.html',
controller: 'TraineesController'
})
.when('/technology', {
templateUrl: 'partials/technology.html',
controller: 'TraineesController'
})
.otherwise({redirectTo:"/technology"});
});
Index.html
<html ng-app="myApp">
<head>
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css"/>
<link rel="stylesheet" type="text/css" href="css/taskman.css"/>
<link href="http://fonts.googleapis.com/css?family=Open+Sans:400,600,300,700" rel="stylesheet" type="text/css">
<script type="text/javascript" src="js/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.10/angular-route.js"></script>
<script type="text/javascript" src="app/route.js"></script>
<script type="text/javascript" src="app/app.js"></script>
</head>
<body>
<a href="#/technology" class="btn btn-sm btn-danger nav-button-margin">
<i class="glyphicon glyphicon-user"></i> Account panel
</a>
<div class="col-sm-12">
<div ng-view></div>
</div><!-- Closing col-sm-12-->
</body>
</html>
app.js
var app = angular.module('myApp', []);
app.controller('TraineesController', function($scope, $http, $log) {
getTrainee(); // Load all available tasks
function getTrainee(){
$http.post("ajax/getTrainee.php").success(function(data){
$scope.trainees = data;
});
};
});
task.html
<div class="widget-box" id="recent-box" ng-controller="TraineesController">
Random text tables
</div>
remove the ; from here:
.when('/technology', {
templateUrl: 'partials/technology.html',
controller: 'TraineesController'
}) // <-----here you have a ; remove it and it will work.
.otherwise({redirectTo:"/technology"});
; broke the chaining and caused a syntax error there.
update:
you can remove this controller:
<body ng-controller="TraineesController">
and instead you can place the controller in the respective templates.
checkout this plunkr demo.
I've made two different plunkers, the first one is a plain app just to do an example of routes magic with angular...
First example, basic routes
var app = angular.module('plunker', ['ngRoute']);
app.controller('MainCtrl', function($scope) {
$scope.technology = 'this is the tech page';
$scope.task = 'this is the task';
});
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider
.when('/technology', {
templateUrl: 'technology.html',
controller: 'MainCtrl'
})
.when('/task', {
templateUrl: 'task.html',
controller: 'MainCtrl'
})
.otherwise({
redirectTo: '/technology'
});
}
]);
The second example is an myApp example based on your application, it's basicaly your application but slightly different...
Second example, your app
// I like to keep the app.js file "clean", what means that this file will only
// load the app modules and declare the DI of the app...
var app = angular.module('myApp', [
'ngRoute', // ngRoutes directive from angularjs
'myAppControllers', // controllers module, u can add how controllers wtv u need
'myAppRoutes', // routes module, you can keep the routes configs separated or in the same file
]);
// start the modules, other way to do this is to put this lines in every
// single controllers or route file, what is ugly
angular.module('myAppRoutes',[]);
angular.module('myAppControllers',[]);

I'm working on my first app. When I open it in the webbrowser I get this error: Uncaught ReferenceError: controller is not defined
at app.js:3
at app.js:15
I got this error after I created the app.js file and tried to link my controller.js to it. Also the routeProvider doesn't seem to work yet. And my placeholders stopt working, which did work before.
I simplified my code to keep it readable. I've got more html files and use bootstrap in combination with JQuery and CSS. Does someone know what's going wrong here?
app.js
(function(){
var myApp = angular.module('myApp', ['ngRoute']).controller('controller', controller)
.config(function($routeProvider, $locationProvider){
$locationProvider.html5Mode(true);
$routeProvider
.when('/main', {
templateUrl: '../main.html',
controller: 'controller'
})
.otherwise({redirectTo: '../main'});
});
})();
controller.js
(function() {
angular.module('controller', ['ngRoute'])
.controller('controller', ['$scope', function ($scope) {
}]);
})();

There are few issues with your code,
(i)Since you have defined controller separately in a single file, you can safely remove it from the initial module.
function(){
var myApp = angular.module('myApp',['ngRoute'])
myApp.config(function($routeProvider, $locationProvider){
$locationProvider.html5Mode(true);
$routeProvider
.when('/main', {
templateUrl: './main.html',
controller: 'controller'
})
.otherwise({redirectTo: '/main'});
});
})();
(ii) You do not need to have ngRoute injected twice, You can just use the globally declared module
(function() {
app.controller('controller', ['$scope', function ($scope) {
}]);
})();

I try to show a view with angular paths. the console does not throw any error or warning.
But equally the view is not displayed.
What am I doing wrong?
index.html
<!DOCTYPE html>
<html lang="en" ng-app="app">

routes.js
var _templateBase = './components';
angular.module('app', [
'ngRoute'
])
.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: _templateBase + '/customer/customer.html' ,
controller: 'customerController',
controllerAs: '_ctrl'
})
.otherwise({
redirectTo: '/'
});
}
]);
costomerService.js
angular.module('app', [])
.factory('customerService', function() {
});
costomerController.js
angular.module('app',[])
.controller('customerController', ['$scope', function($scope, customerService) {
//
}]);
It's wrong? Because the view is not displayed? I'm using obsolete mertodos, guide me lleguar many tutorials there.
Thanks so they can help.
This creates your app because you have included the second parameter (an array of dependencies to inject):
angular.module('app', [
'ngRoute'
])
Remove the second parameter on your other angular.module() definitions because that is causing a new app to be created each time.
angular.module('app') <-- no second parameter tells it to use the existing 'app' module
.factory('customerService', function() {
});
angular.module('app') <-- no second parameter tells it to use the existing 'app' module
.controller('customerController', ['$scope', 'customerService', function($scope, customerService) {
//
}]);
I added customerService to your injection array on your controller definition because the array elements have to match up exactly to your function parameters.
Also, if you are using controllerAs syntax as you have done on your route definition then you may not want to inject $scope into your controller.
I am working with AngularJS and using the ngRoute for routing.
I was wondering if this is normal behavior for Angular when it routes to the "otherwise" part and activates all controllers?
var angularApp = angular.module('AngularApp', ['ngRoute']);
angularApp.config(['$routeProvider',
function ($routeProvider) {
$routeProvider
.when('/ExpenseOverview', {
controller: 'ExpenseOverviewController',
templateUrl: 'Angular/Views/ExpenseOverview.vbhtml'
})
.when('/AddExpense',
{
controller: 'AddExpenseController',
templateUrl: 'Angular/Views/AddExpense.vbhtml'
})
.otherwise({ redirectTo: '/ExpenseOverview' });
}]);
I have put an alert at the very top in each controller, even my factory. And on startup, all alerts are shown. Instead of going to "ExpenseOverview" at first, it checks both my controllers and not just the one that is bound to "/ExpenseOverview".
What could be the cause of this?
EDIT: Knowing it's normal for Angular to access all controllers on startup, the main problem isn't fixed yet. This is explained in another thread on StackOverflow. I thought this had something to do with it, because I had no idea that it was normal behavior for Angular to do this.
I could say that this thread is closed, because I have an answer to my question now.
Angular does not access every controller on start up, however, ngRoute does. Any initialization code in a controller that has a corresponding route entry in $routeProvider, will run at initialization.
Here's an example of this at play: http://plnkr.co/edit/WsvbKhcR74yoX80bskdb?p=preview

I'm trying to put together a basic angularjs web page through django (but not really using django for this example). I tried to copy an example exactly, but it's not working. The partial and the controller are not loading. The url is updated, so I know the app is loading. But I don't see it hitting my web server at all for the partial or the data. Help would be appreciated.
Here is the simplest code I could put together.
test.html:
<!doctype html>
<html ng-app="ciqApp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.14/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.14/angular-route.js"></script>
<script type="text/javascript" src="js/app.js"></script>
<script type="text/javascript" src="js/controllers.js"></script>
</head>
<body>
TEST
<div ng-view>
</div>
</body>
</html>
js/app.js
var ciqApp = angular.module('ciqApp', [
'ngRoute',
'ciqControllers'
]);
ciqApp.config(['$routeProvider',
function($routeProvider){
$routeProvider.
when('/questions', {
templateURL: '/static/partials/question-list.html',
controller: 'QuestionListCtrl'
}).
otherwise({
redirectTo: '/questions'
});
}]);
js/controllers.js
var ciqControllers = angular.module('ciqControllers', []);
ciqControllers.controller('QuestionListCtrl', ['$scope', '$http',
function ($scope, $http) {
$http.get('/get_questions').success(function(data) {
$scope.questions = data;
});
}]);
TemplateURL should be TemplateUrl. Also, you can try to remove the first slash from your templateUrl path and see if that makes a difference: So:
templateURL: '/static/partials/question-list.html',
becomes:
templateUrl: 'static/partials/question-list.html',
I'm using bootstrap to display a modal and want it to be shown on click of a anchor tag as a route.
But i'm getting a module error & can't seem to figure out how to resolve it.
HTML
<div ng-view>
<div ng-controller="DetailPageCtrl">
Click here to open modal!
</div>
<script type="text/ng-template" id="modalContainer">
<div ng-controller="ProfileModalCtrl"></div>
</script>
</div>
JS
var app = angular.module('plunker', ['ui.bootstrap']);
app.config(function($routeProvider) {
$routeProvider
.when('/profile', {
templateUrl : 'modalContainer',
controller : 'ProfileModalCtrl'
});
})
app.controller('DetailPageCtrl', function($scope) {
console.log("detail page");
});
app.controller('ProfileModalCtrl', function($scope, $modal) {
$modal.open({templateUrl : 'modal.html'});
});

Demo is plagued with problems. You haven't included angular-route.js. You didn't provide a default path using otherwise and you placed html within ng-view
/* include script tag with `angular-route.js , then inject as dependency*/
var app = angular.module('plunker', ['ui.bootstrap', 'ngRoute']);
app.config(function($routeProvider) {
$routeProvider.when('/', {
templateUrl: 'default'
})
.when('/profile', {
templateUrl: 'modalContainer',
controller: 'ProfileModalCtrl'
}).otherwise({
redirectTo: '/'
})
});
<div ng-view><!-- leave empty --></div>
DEMO
You will also run into problems declaring same ng-controller in markup as in route config...pick one or the other
Your plunker is missing the ngRoute dependency. In newer versions of angular, ngRoute is a separate library that needs to included separately and declared as a module dependency to your app module:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.4/angular.js"></script>
<script src="http://code.angularjs.org/1.2.4/angular-route.js"></script>
var app = angular.module('plunker', ['ngRoute', 'ui.bootstrap']);
Also, your routes are not fully defined.
Also, your templates (<script type="text/ng-template">) are defined inside the <div ng-view> element. ng-view is a directive which will replace the content of host div element when route is resolved, so a better place for your templates is outside of ng-view element.
Fixed PLUNKER
var app = angular.module('plunker', ['ngRoute', 'ui.bootstrap']);
app.config(function($routeProvider) {
$routeProvider
.when('/profile', {
templateUrl : 'modalContainer',
controller : 'ProfileModalCtrl'
})
.when('/detail', {
templateUrl : 'detail.html',
controller : 'DetailPageCtrl'
})
.otherwise({redirectTo: '/detail'});
});
app.controller('DetailPageCtrl', function($scope) {
console.log("detail page");
});
app.controller('ProfileModalCtrl', function($scope, $modal) {
$modal.open({templateUrl : 'modal.html'});
});
