I'm getting the following error:
Error: $injector:unpr Unknown Provider
Unknown provider: _planetsProvider <- _planets <- SearchController
.API get request is working fine and my SearchController.js is also triggered, but I'm still getting the error above. I have tried almost all suggestions from StackOverflow and official document. How can I fix it?
Here's my code: (Plunker link)
app.js
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config( function($routeProvider) {
$routeProvider
.when('/', { templateUrl: '/views/home.html',
controller: 'HomeController' })
.when('/login', { templateUrl: '/views/login.html',
controller: 'LoginController' })
.when('/search', { templateUrl: '/views/search.html',
controller: 'SearchController',
resolve:{
_planets: function(myService)
{
console.log("asdas");
return myService.getRequestForPlanets();
}
}
})
});
SearchController.js
angular.module('myApp').controller('SearchController', function($scope, myService, _planets, $rootScope) {
$scope.message = 'This is Show orders screen';
$scope.planets=_planets;
console.log(_planets);
});
myService.js
angular.module('myApp').service('myService', function($http, $rootScope, $location, $q)
{
$rootScope.loading = false;
this.getRequestForPlanets=function()
{
$rootScope.loading = true;
var deferred = $q.defer();
$http.get('https://swapi.co/api/planets')
.then(function(response){
$rootScope.loading = false;
console.log(response.data.results);
deferred.resolve(response.data.results);
})
.catch(function(response){
deferred.reject(response);
});
return deferred.promise;
}
});

Based on the plnkr link you provided: https://plnkr.co/edit/WRh3z5HTGby6nT1G8ovi?p=preview
Your controller is being instantiated twice, once in your routes, in app.js here:
.when('/search', { templateUrl: '/views/search.html',
controller: 'SearchController',
...
and again in your view in search.html here:
<div ng-controller="SearchController">
<p>{{message}}</p>
...
Since the SearchController has already been injected into the app by your routes, the second time it's instantiated in the view, it throws the Unknown Provider error.
If you remove ng-controller="SearchController" from search.html it should fix the issue that you're having.
Hope that helps!

Your code almost works well. you can just add ng-style:
app.controller('homeController', function($scope) {
console.log("home called");
$scope.myStyle = {
width: '0px'
};
$scope.openNav = function() {
$scope.myStyle.width = '250px';
}
$scope.closeNav = function() {
$scope.myStyle.width = '0px';

hi I'm doing a aplication with angular, well in this app I need show map and makers, but first step I need the map, now I'am having problem in this part ok, I'm very new in angular I make maps with jquery and javascript now I tried to make the same steps and nop work yet. well I thing that this part is the important. controller of map.
mapController.js
(function(){
angular.module('mapCtrl', [])
.controller('MapController', function($scope) {
function initialize() {
var options = {
googleApiKey: '',
locationColumn: 'geometry',
map_center: [-16.494898, -68.133553],
locationScope: 'La Paz'
};
var self = this;
options = options || {};
this.googleApiKey = options.googleApiKey || "";
this.locationColumn = options.locationColumn || "geometry";
this.locationScope = options.locationScope || "";
this.defaultZoom = options.defaultZoom || 13;
this.map_centroid = new google.maps.LatLng(options.map_center[0], options.map_center[1]);
this.myOptions = {
zoom: this.defaultZoom,
center: this.map_centroid,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
//$scope.map = new google.maps.Map($("#map")[0], this.myOptions);
$scope.map = new google.maps.Map(document.getElementById('map'), this.myOptions);
//this.map = new google.maps.Map($("#map")[0], this.myOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
});
})();
I tried with getElementById() and dont work. Now the view.
In the express framework the route is /public/app/views/index.html, the
route.app.js is:
(function(){
angular.module('app.routes', ['ngRoute'])
.config(function($routeProvider, $locationProvider) {
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
$routeProvider
.when('/', {
templateUrl: 'app/views/pages/home.html',
controller: 'MapController',
controllerAs: 'main'
})
.when('/login', {
templateUrl: 'app/views/pages/login.html'
})
.when('/about', {
templateUrl: 'app/views/pages/about.html'
})
.when('/users', {
templateUrl: 'app/views/pages/users.html'
});
// get rid of the hash in the URL
});
})();
the app.js
(function(){
angular.module('myApp', [
'ngAnimate',
'app.routes',
'mainCtrl',
'userCtrl',
'mapCtrl',
'userService',
'authService'
]);

I'm new to AngularJS and I'm trying to declare a second controller to a new view in my page. I have a logincontroller and when I succeed the login I get to the Home.html.
When opening Home.html I get the following error below..It looks like it can't recognize my ModelController/ModalService..What am I missing here?
Error: [$injector:unpr] http://errors.angularjs.org/1.5.0-beta.1/$injector/unpr?p0=ModalServiceProvider%20%3C-%20ModalService%20%3C-%20ModalController

You need to include app.js after including services and controllers. And controllers after services.
it should be like this:
<script src="Scripts/Services/ModalService.js"></script> <!--ModalService is being defined here -->
<script src="Scripts/Services/AuthenticationService.js"></script>
<script src="Scripts/Controller/LoginController.js"></script>
<script src="Scripts/Controller/ModalController.js"></script> <!-- ModalService is being injected here -->
<script src="Scripts/MyApp.js"></script> <!-- All of the things are set in place here -->
In fact, the best practice is to include all of them in the bottom of your <body>.
I found the answer..The problem was that I was missing a comma :(
ModalService.js should look like this:
angular.module('Modal', []);
angular.module('Modal')
.factory('ModalService', <------ COMMA MISSING :(
['$http',
function ($http) {
var service = {};
return service;
}
]);
I have a simple controller (logincontroller) which gets initiated twice when loading login.html, however I do not know why that happens.
MyApp.js:
angular.module('PVM', [
'Authentication',
'Modal',
'ngRoute'
])
.config([
'$routeProvider', function($routeProvider) {
$routeProvider
.when('/Login', {
controller: 'LoginController',
templateUrl: 'Login.html'
})
.when('/Home', {
controller: 'ModalController',
templateUrl: 'Home.html'
})
.otherwise({
redirectTo: '/Login'
});
}
]);
LoginController.js:
angular.module("Authentication")
.controller("LoginController",
[
"$scope", "$rootScope", "$location", "AuthenticationService",
function($scope, $rootScope, $location, AuthenticationService) {
AuthenticationService.ClearCredentials();
$scope.login = function() {
var foo = "bar"; //Breakpoint hits here twice when loading login.html
};
}
]);

</body>
</html>
Login.html:
<div class="container centeredDiv" ng-controller="LoginController">
<p>Login page</p>
</div>
Because your controller gets executed at 2 places.
From login.html - ng-controller
<div class="container centeredDiv" ng-controller="LoginController">
<p>Login page</p>
</div>
From controller associated with route - /Login
.when('/Login', {
controller: 'LoginController',
templateUrl: 'Login.html'
})
How to fix? You should remove the ng-controller attribute from login.html
You do not need the ng-controller in your template login.html because it is in your route. Simply remove it and that should do the trick.
