any issues in this controller function? - javascript

when i use routers without controllers then my routers are working fine but when i add controllers in it. then my routers stop working... can anyone please tell me about my issues in routers functions?
LOGIN CONTROLLER:
angular.module('starter', ['ionic'])
.controller('LoginCtrl', function($scope, LoginService, $ionicPopup, $state) {
$scope.login = function() {
console.log("LOGIN user: " + $scope.username + " - PW: " + $scope.password);
LoginService.loginUser($scope.username, $scope.password).success(function(data) {
console.log("Login Successful");
$state.go('home');
}).error(function(data) {
var alertPopup = $ionicPopup.alert({
title: 'Login failed!',
template: 'Please check your credentials!'
})
})
}
});
ROUTERS CODE
angular.module('starter', ['ionic'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/home',
templateUrl: 'page2.html',
controller: 'HomeCtrl'
})
.state('login', {
url: '/login',
templateUrl: 'index.html',
controller: 'LoginCtrl'
})
$urlRouterProvider.otherwise('/login');
});

Your controller is wrongly declared. Remove injector from your module while creating controller. Something like
angular.module('starter')
.controller('LoginCtrl', function($scope, LoginService, $ionicPopup, $state) {
//...
});
Because of these reasons, it is best to have your module created in separate file. So you would have
module.js
angular.module('starter', ['ionic'])
config.js
angular.module('starter').config(function(){});
controller.js
angular.module('starter').controller('', function(){});

angular.module('starter', ['ionic'])
and
angular.module('starter')
are two entirely different concept . While [] converts the the method to a setter method. Meaning It will create a new instance of starter module. But if you do not use the third bracket it becomes a getter method meaning it will return already declared module.
Thats why you need to use
angular.module('starter').controller('', function(){});
for details look here

angular.module('starter', ['ionic']) ,
this code create an instance of angular app named starter. you should create an instance of an app only once. but you created twice here.
only use
angular.module('starter')
to use the app while declaring controller or config . but you should be careful that first create instance then use it.
that means
angular.module('starter', ['ionic'])
should use in the portion which will execute first .

Loading modules in Angularjs

I have a problem trying to load some modules.
controller1.js:
angular.module('LPC')
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
And app.js:
var app = angular.module('mis_peliculas', []);
app.config(function($routeProvider){
$routeProvider
.when("/pagina_principal",{
templateUrl: "views/pagina_principal.html",
controller: "lista_peliculas_controller"
})
.when("/lista_peliculas",{
templateUrl: "views/lista_peliculas.html",
controller: "lista_peliculas_controller"
})
.when("/lista_series",{
templateUrl: "views/lista_series.html",
controller: "lista_series_controller"
})
.otherwise({
redirectTo: "/pagina_principal"
})
});
The console says that there is a problem with the injector.
Can you find the error?
You must add angular-route.js . Reference
The ngRoute module provides routing and deeplinking services and
directives for AngularJS apps.
How do you fix it?
var app = angular.module('mis_peliculas', ['ngRoute','LPC']);
And
angular.module('LPC', [])
Update your code to use right module name:
angular.module('mis_peliculas')
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
and if you want to use separate modules, you need to initiliaze it first and inject it into your main module
angular.module('LPC',[])
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
var app = angular.module('mis_peliculas', ['LPC']);
I assume your routing is already set correctly.
without the complete log of the error i can't be more precise, but i think that the injection error could be related to your module not being instantiated.
try to change
angular.module('LPC') //here you get a reference to a module, that could cause your error
to
angular.module('LPC', []) //here you instantiate a module
You need to pass in the 'LPC' Module to your app 'mis_peliculas' module for it use the 'lista_peliculas_controller' Controller which is in 'LPC' Module.
Try this code
angular.module('LPC',[])
.controller('lista_peliculas_controller', ['$scope', function($scope) {
$scope.hola="hola peliculas";
}]);
This should be your controller1.js and should be defined before you define your app. Now the app.js should look like
var app = angular.module('mis_peliculas', ['LPC']);
app.config(function($routeProvider){
$routeProvider
.when("/pagina_principal",{
templateUrl: "views/pagina_principal.html",
controller: "lista_peliculas_controller"
})
.when("/lista_peliculas",{
templateUrl: "views/lista_peliculas.html",
controller: "lista_peliculas_controller"
})
.when("/lista_series",{
templateUrl: "views/lista_series.html",
controller: "lista_series_controller"
})
.otherwise({
redirectTo: "/pagina_principal"
})
});
This should remove all the errors and you should be able to use the controller from other module.
Hope it helps

Link module from external file in AngularJS

I'm working on new project and I want to use two modules placed in separated files. Unfortunetaly, when I try to declare second in my root one I receive an error
Uncaught Error: [$injector:modulerr]
So, here is my root file, app.js:
var beerMe = angular.module("beerMe", ["admin", "ngRoute"])
.config(["$routeProvider", function($routeProvider) {
$routeProvider
.when("/home", {
templateUrl: "../views/home/home.html",
controller: "MyCtrl"
})
.otherwise({
redirectTo: "/home"
})
}])
.controller("MyCtrl", ["$scope", function($scope) {
}]);
And second one, which I want to bind, admin.js:
var admin = angular.module("admin", ["firebase", "ngRoute"]);
admin.config(["$routeProvider", function($routeProvider) {
$routeProvider
.when("/", {
templateUrl: "views/add.html",
controller: "AdminCtrl"
}).when ("/edit", {
templateUrl: "views/edit.html",
controller: "AdminCtrl"
}).otherwise({
redirectTo: "/"
})
}]);
admin.controller("AdminCtrl", ["$scope", "$firebaseArray", function($scope, $firebaseArray) {
// my code goes here
}]);
In admin.js I connnect to firebase and I want to have access to all data from my module "beerMe".
I'd be very grateful if you could help me to figure out why there's a problem with binding these two.
Change var admin = angular.module("admin", ["firebase", "ngRoute"]);
to var admin = angular.module("admin");
and change root module like this
var beerMe = angular.module("beerMe", ["admin", "ngRoute", "firebase"])
It looks like your dependencies are the wrong way round. Having admin as a dependency of beerMe will not make the beerMe module available in your admin module.
If you want your admin module to be able to access data from inside the beerMe module then beerMe should be a dependency of admin.
var admin = angular.module('admin', ['firebase', 'ngRoute', 'beerMe']);

AngularJS and RequireJS add controller to view

I have a problem with adding a Angular controller to my HTML view. The angular way of doing this is: ng-controller="<controller>". But because I am using RequireJs I have to do this in a different way. I have to add a sub page to every controller and view:
define(['app', 'login/LoginController'], function (app, LoginController) {
app.config(function ($routeProvider, $locationProvider) {
$routeProvider.when('/', {
templateUrl: "modules/" + 'login/login.html',
controller: LoginController
});
});
app.controller('LoginController', LoginController);
});
This way I can define my where my controller is and where my view is.
Problem
Now I have a header.html in which I want to include a menu.html. this can be done via: ng-include="'modules/menu/menu.html'". This works fine. But how can I add a controller to this menu.html?
I have tried: ng-controller="MenuController" but then I get the error: 'Error: [ng:areq] Argument 'MenuController' is not a function, got undefined'. So I do not know how I should add a controller to my menu.html with RequireJS.
MenuController
my MenuController looks as follows:
define(['$'], function ($) {
'use strict';
var MenuController = function ($location, menu, $scope) {
$scope.info="testing123";
};
return MenuController;
});
Anyone knows how I should do this?
You can for example use multiple views in the same controllerwith $stateProvider:
app.config(function ($stateProvider, $locationProvider) {
$stateProvider
.state('login', {
url: '/',
views: {
'menu': {
templateUrl: 'modules/menu/menu.html',
controller: MenuController
},
'login': {
templateUrl: 'modules/login/login.html'
controller: LoginController
}
}
});
});
Then in your template to call them you just need to do something like:
<div ui-view="menu"></div>
<div ui-view="login"></div>
You can see more info on github ui-router.

Using ocLazyLoad to lazy load a controller with $stateProvider

I'm having issues using oclazyload with $stateProvider.
I have specified that the controller .js should be loaded in the router config, and it does,' but it's not available to use as an ng-controller attribute in the file loaded in templateURL.
ui-route config:
core
.run(
[ '$rootScope', '$state', '$stateParams',
function ($rootScope, $state, $stateParams) {
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
}
]
)
.config(
[ '$stateProvider', '$urlRouterProvider',
function ($stateProvider, $urlRouterProvider) {
console.info('Routing ...');
$urlRouterProvider
.otherwise('/app/dashboard');
$stateProvider
.state('app', {
abstract: true,
url: '/app',
templateUrl: 'templates/app.html',
})
.state('app.orders', {
abstract: true,
url: '/orders',
templateUrl: 'templates/orders/orders.html',
})
.state('app.orders.index', {
url: '/index',
templateUrl: 'templates/orders/index.html',
resolve: {
deps: ['$ocLazyLoad',
function( $ocLazyLoad ){
console.info('Path ot order controller in route config',Momento.paths.js + 'controllers/orders/index.js');
return $ocLazyLoad.load([
Momento.paths.js + 'controllers/orders/index.js'
])
}
]
}
})
}
]
)
;
And my templateURL file starts:
<div class="" id="" ng-controller="OrdersIndexController">...</div>
But when it loads, console throws the error:
<info>orders/index controller loaded controllers/orders/index.js:3
<info>Now I've finished loading the controller/order/index.js config/ui-router.js:69
<info>orders template loaded VM30437:1 (<-- this is the app.orders abstract template with ui-view directive ready for app.orders.index view)
<error>Error: [ng:areq] Argument 'OrdersIndexController' is not a function, got undefined
... <trace>
So the file is loaded correctly by lazyload, confirmed by console output above and network tab in developer tools, but it's not available in the templateURL to use as controller? Does it need to be aliased either in router config using controller:'' key or in template? Does it need to be specifically attached to the (only) module in this app?
What am I missing?
PS: confirming that the name of the controller is in fact OrdersIndexController:
core
.controller('OrdersIndexController', [
'Model', '$scope', '$window',
function( Model, $scope, $window){
console.info("OrdersIndexController fired");
}
]);
You have to register your controller with
angular.module("myApp").controller
Working
angular.module("myApp").controller('HomePageController', ['$scope', function ($scope) {
console.log("HomePageController loaded");
}]);
Not working
var myApp = angular.module("myApp")
myApp.controller('HomePageController', ['$scope', function ($scope) {
console.log("HomePageController loaded");
}]);
Inside the function function($ocLazyLoad){} you must to declare the name of module that contains the controller and the name of file "to lazy load"
function( $ocLazyLoad ){
return $ocLazyLoad.load(
{
name: 'module.name',
files: ['files']
}
);
}
If you use the current documented way for ocLazyLoad 1.0 -> With your router
...
resolve: { // Any property in resolve should return a promise and is executed before the view is loaded
loadMyCtrl: ['$ocLazyLoad', function($ocLazyLoad) {
// you can lazy load files for an existing module
return $ocLazyLoad.load('js/AppCtrl.js');
}]
}
then in js/AppCtrl.js
You have something like this:
angular.module("myApp").controller('DynamicNew1Ctrl', ['$scope', function($scope) {
$scope.name = "Scoped variable";
console.log("Controller Initialized");
}]);
Note that with angular.module("myApp") you are attaching the new controller to an existing module, in this case the mainApp, so any of new dynamic controllers can use the app dependencies.
but you can define a new module an inject your dependencies, as described here, the later is used commonly when you estructure your app with a plugin architecture and you want to isolate the dynamic modules so they only have access to some especific dependencies

AngularJS dynamic routing

I currently have an AngularJS application with routing built in.
It works and everything is ok.
My app.js file looks like this:
angular.module('myapp', ['myapp.filters', 'myapp.services', 'myapp.directives']).
config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/', { templateUrl: '/pages/home.html', controller: HomeController });
$routeProvider.when('/about', { templateUrl: '/pages/about.html', controller: AboutController });
$routeProvider.when('/privacy', { templateUrl: '/pages/privacy.html', controller: AboutController });
$routeProvider.when('/terms', { templateUrl: '/pages/terms.html', controller: AboutController });
$routeProvider.otherwise({ redirectTo: '/' });
}]);
My app has a CMS built in where you can copy and add new html files within the /pages directory.
I would like to still go through the routing provider though even for the new dynamically added files.
In an ideal world the routing pattern would be:
$routeProvider.when('/pagename', { templateUrl: '/pages/pagename.html', controller: CMSController });
So if my new page name was "contact.html" I would like angular to pick up "/contact" and redirect to "/pages/contact.html".
Is this even possible?! and if so how?!
Update
I now have this in my routing config:
$routeProvider.when('/page/:name', { templateUrl: '/pages/home.html', controller: CMSController })
and in my CMSController:
function CMSController($scope, $route, $routeParams) {
$route.current.templateUrl = '/pages/' + $routeParams.name + ".html";
alert($route.current.templateUrl);
}
CMSController.$inject = ['$scope', '$route', '$routeParams'];
This sets the current templateUrl to the right value.
However I would now like to change the ng-view with the new templateUrl value. How is this accomplished?
angular.module('myapp', ['myapp.filters', 'myapp.services', 'myapp.directives']).
config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/page/:name*', {
templateUrl: function(urlattr){
return '/pages/' + urlattr.name + '.html';
},
controller: 'CMSController'
});
}
]);
Adding * let you work with multiple levels of directories dynamically.
Example: /page/cars/selling/list will be catch on this provider
From the docs (1.3.0):
"If templateUrl is a function, it will be called with the following
parameters:
{Array.} - route parameters extracted from the current
$location.path() by applying the current route"
Also
when(path, route) : Method
path can contain named groups starting with a colon and ending with a star: e.g.:name*. All characters are eagerly stored in $routeParams under the given name when the route matches.
Ok solved it.
Added the solution to GitHub - http://gregorypratt.github.com/AngularDynamicRouting
In my app.js routing config:
$routeProvider.when('/pages/:name', {
templateUrl: '/pages/home.html',
controller: CMSController
});
Then in my CMS controller:
function CMSController($scope, $route, $routeParams) {
$route.current.templateUrl = '/pages/' + $routeParams.name + ".html";
$.get($route.current.templateUrl, function (data) {
$scope.$apply(function () {
$('#views').html($compile(data)($scope));
});
});
...
}
CMSController.$inject = ['$scope', '$route', '$routeParams'];
With #views being my <div id="views" ng-view></div>
So now it works with standard routing and dynamic routing.
To test it I copied about.html called it portfolio.html, changed some of it's contents and entered /#/pages/portfolio into my browser and hey presto portfolio.html was displayed....
Updated
Added $apply and $compile to the html so that dynamic content can be injected.
I think the easiest way to do such thing is to resolve the routes later, you could ask the routes via json, for example. Check out that I make a factory out of the $routeProvider during config phase, via $provide, so I can keep using the $routeProvider object in the run phase, and even in controllers.
'use strict';
angular.module('myapp', []).config(function($provide, $routeProvider) {
$provide.factory('$routeProvider', function () {
return $routeProvider;
});
}).run(function($routeProvider, $http) {
$routeProvider.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
}).otherwise({
redirectTo: '/'
});
$http.get('/dynamic-routes.json').success(function(data) {
$routeProvider.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
});
// you might need to call $route.reload() if the route changed
$route.reload();
});
});
In the $routeProvider URI patters, you can specify variable parameters, like so: $routeProvider.when('/page/:pageNumber' ... , and access it in your controller via $routeParams.
There is a good example at the end of the $route page: http://docs.angularjs.org/api/ng.$route
EDIT (for the edited question):
The routing system is unfortunately very limited - there is a lot of discussion on this topic, and some solutions have been proposed, namely via creating multiple named views, etc.. But right now, the ngView directive serves only ONE view per route, on a one-to-one basis. You can go about this in multiple ways - the simpler one would be to use the view's template as a loader, with a <ng-include src="myTemplateUrl"></ng-include> tag in it ($scope.myTemplateUrl would be created in the controller).
I use a more complex (but cleaner, for larger and more complicated problems) solution, basically skipping the $route service altogether, that is detailed here:
http://www.bennadel.com/blog/2420-Mapping-AngularJS-Routes-Onto-URL-Parameters-And-Client-Side-Events.htm
Not sure why this works but dynamic (or wildcard if you prefer) routes are possible in angular 1.2.0-rc.2...
http://code.angularjs.org/1.2.0-rc.2/angular.min.js
http://code.angularjs.org/1.2.0-rc.2/angular-route.min.js
angular.module('yadda', [
'ngRoute'
]).
config(function ($routeProvider, $locationProvider) {
$routeProvider.
when('/:a', {
template: '<div ng-include="templateUrl">Loading...</div>',
controller: 'DynamicController'
}).
controller('DynamicController', function ($scope, $routeParams) {
console.log($routeParams);
$scope.templateUrl = 'partials/' + $routeParams.a;
}).
example.com/foo -> loads "foo" partial
example.com/bar-> loads "bar" partial
No need for any adjustments in the ng-view. The '/:a' case is the only variable I have found that will acheive this.. '/:foo' does not work unless your partials are all foo1, foo2, etc... '/:a' works with any partial name.
All values fire the dynamic controller - so there is no "otherwise" but, I think it is what you're looking for in a dynamic or wildcard routing scenario..
As of AngularJS 1.1.3, you can now do exactly what you want using the new catch-all parameter.
https://github.com/angular/angular.js/commit/7eafbb98c64c0dc079d7d3ec589f1270b7f6fea5
From the commit:
This allows routeProvider to accept parameters that matches
substrings even when they contain slashes if they are prefixed
with an asterisk instead of a colon.
For example, routes like edit/color/:color/largecode/*largecode
will match with something like this
http://appdomain.com/edit/color/brown/largecode/code/with/slashs.
I have tested it out myself (using 1.1.5) and it works great. Just keep in mind that each new URL will reload your controller, so to keep any kind of state, you may need to use a custom service.
Here is another solution that works good.
(function() {
'use strict';
angular.module('cms').config(route);
route.$inject = ['$routeProvider'];
function route($routeProvider) {
$routeProvider
.when('/:section', {
templateUrl: buildPath
})
.when('/:section/:page', {
templateUrl: buildPath
})
.when('/:section/:page/:task', {
templateUrl: buildPath
});
}
function buildPath(path) {
var layout = 'layout';
angular.forEach(path, function(value) {
value = value.charAt(0).toUpperCase() + value.substring(1);
layout += value;
});
layout += '.tpl';
return 'client/app/layouts/' + layout;
}
})();
