How to use $routeProvider and custom module in config function?
angular.module('urls', []).
factory('$urls', function (
$location
) {
var $urls = {};
$urls.login = function () {
var url = '/login';
return url;
}
return $urls;
});
angular.module('app', ['urls']).
config(function ($routeProvider, $urls) {
$routeProvider.
when($urls.login(), { controller: PageCtrl, templateUrl: 'tem.html' }).
otherwise({ redirectTo: $urls.login() });
});
As I commented you can create a provider instead of a factory and put the URLs in that as the central place:
angular.module('urls', []).
provider('urls', function (){
this.$get = function(){
var obj = {}
obj.login = function(){ return '/login';}
//more urls here, you don't really need function though
return obj;
}
});
angular.module('app', ['urls']).
config(function ($routeProvider, urlsProvider) {
$routeProvider.
when(urlsProvider.login(), { controller: PageCtrl, templateUrl: 'tem.html' }).
otherwise({ redirectTo: urlsProvider.login() });
});
However, you can not inject the $location service to the urls provider. But if you really want to use $location, you can create another service that uses both the urls service and $location service to achieve the same effect like this:
angular.module('urls', []).
service('myUrlService', function (urls, $location){
this.goToLogin = function(){$location.path(urls.login());}//just an example
});
Then you can inject myUrlService to your controllers and do things like this:
myUrlService.goToLogin();

I have bunch of JSON models in my project and I need to show different models depends on user's actions.
Here is Angular router code:
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'views/home.html',
controller: 'HomeCtrl'
}).when('/doc/:section, {
templateUrl: 'views/doc.html',
controller: 'DocCtrl'
})
.otherwise({
redirectTo: '/'
});
}]);
And here is DocCtrl.js file:
app.controller('DocCtrl', ['$scope', '$http', 'JSONModelsService',
function ($scope, $http, JSONModelsService) {
var formData = {};
$scope.group = {};
$scope.sections = [];
JSONModelsService.get([section])
.then(function (response) {
console.log(response);
$scope.group = response.data.groups[0];
$scope.sections = $scope.group.sections;
});
}]);
I basically need to make section dynamic so I can show different models in my views. However, I'm confused how I can do it. I just have a folder called JSONModels with multiple json files.
If I understand your question correctly, you are aiming at replacing the [section] part of your code with an actual section identifier?
When a user visits your /doc/:section route, e.g. /doc/my-doc you can access the :section part by injecting the $routeParams service into your controller.
app.controller('DocCtrl', ['$scope', '$http', '$routeParams', 'JSONModelsService',
function ($scope, $http, $routeParams, JSONModelsService) {
...
Using the $routeParams service, you have access to your route parameters. So you can simple access the :section parameter, by reading it off $routeParams.section.
A full example (of what I think you're trying to achieve):
app.controller('DocCtrl', ['$scope', '$http', '$routeParams', 'JSONModelsService',
function ($scope, $http, $routeParams, JSONModelsService) {
var formData = {};
$scope.group = {};
$scope.sections = [];
JSONModelsService.get([$routeParams.section])
.then(function (response) {
console.log(response);
$scope.group = response.data.groups[0];
$scope.sections = $scope.group.sections;
});
}]);

I am able to lazy load angularjs with the help of requirejs. But, how can I load modules that needs to be associated to the controller?
My example configuration in app.js looks like the following, loading all the providers and keeping a reference.
var app = angular.module('myApp', ['ui.router'])
var cacheProviders = {};
app.getProvider = function () {
return cacheProviders.$provide;
}
app.getCompileProvider = function () {
return cacheProviders.$compileProvider;
}
app.getControllerProvider = function () {
return cacheProviders.$controllerProvider;
}
app.getFilterProvider = function () {
return cacheProviders.$filterProvider;
}
app.config(['$stateProvider', '$urlRouterProvider', '$controllerProvider', '$compileProvider', '$filterProvider', '$provide',
function ($stateProvider, $urlRouterProvider, $controllerProvider, $compileProvider, $filterProvider, $provide) {
(function () {
cacheProviders.$controllerProvider = $controllerProvider;
cacheProviders.$compileProvider = $compileProvider;
cacheProviders.$filterProvider = $filterProvider;
cacheProviders.$provide = $provide;
})();
var lazyCtrlLoad = function (controllerName) {
return ["$q", function ($q) {
var deferred = $q.defer();
require([controllerName], function () {
deferred.resolve();
});
return deferred.promise;
}];
}
$stateProvider.state('main.view2b', {
url: '/view2b',
templateUrl: 'forms/empl/searchEmplForm.html',
controllerAs: 'srchC',
controller: 'searchEmplCtrl',
resolve: {
loadOtherCtrl: lazyCtrlLoad('searchEmplCtrl')
}
})
In my other module, I am trying to register controllers, load services..
define([
'angular', 'angularResource'
], function (angular) {
angular.module('myApp')
.getControllerProvider()
.register(ctrl, ...)
But, while loading service below, I need access to $resource which is part of ngResource module in angularResource.
angular.module('myApp')
.getProvider().service('deptService', ['$resource', function ($resource) {
return $resource('/dept/:dept', {dept: '#_dept'});
}])
How can I load ngResource while initalizing the javascript controllers/services lazily?
Take a look to AngularAMD here. It allows you to load controllers in the ui-router without using lazyload. This AngularAMD is used to integrate requireJs and Angular.
$stateProvider
.state('home', {
url: '',
views: {
'#': angularAmd.route({
templateUrl: 'ngApplication/application/shared/layouts/basic/basicTplView.html',
controllerUrl: 'ngApplication/application/shared/layouts/basic/basicTplCtrl.js',
controller: 'basicTplCtrl'
}),
'header#home': angularAmd.route({
templateUrl: 'ngApplication/application/shared/layouts/header/headerView.html',
controllerUrl: 'ngApplication/application/shared/layouts/header/headerCtrl.js',
controller: 'headerCtrl'
})
},
});
Also, you are using requirejs, you can load all the dependencies for an specific controller using the define syntax of requireJs. Let's say you want to create a loginCtroller in a separately file, and this controller depends on another angular service:
define(['app', 'transformRequestAsFormPostService'], function (app) {
app.controller('loginCtrl', ['$scope', '$rootScope', '$sce', '$http', '$state', 'transformRequestAsFormPostService', function ($scope, $rootScope, $sce, $http, $state, transformRequestAsFormPost) {
$scope.login = function () {
/*do something here using the service*/
};
}]);
});
Here, the dependency called transformRequestAsFormPostService is another file, I defined it in the main.js (requireJs confifguration file) and it's defined using the same approach than the loginCtrol. Now I am using it in my project and its working so far so good.

I have a basic angular setup. I want to add another factory service so that the mainCtrl can use it.
Here is my controller.js
angular.module('Manalator.controllers', [])
.controller('MainCtrl', ['$scope', function ($scope, manaFactory) {
manaFactory.testString();
}]);
Here is my services.js
angular.module('Manalator.services', [])
.factory('cordovaReady', [function () {
return function (fn) {
var queue = [],
impl = function () {
queue.push([].slice.call(arguments));
};
document.addEventListener('deviceready', function () {
queue.forEach(function (args) {
fn.apply(this, args);
});
impl = fn;
}, false);
return function () {
return impl.apply(this, arguments);
};
};
}])
.factory('manaFactory', [function(){
this.testString = function(){
return 'This works';
};
}]);
Here is my routes.js
angular.module('Manalator', ['ngRoute', 'Manalator.services', 'Manalator.controllers'])
.config(function ($routeProvider) {
$routeProvider
.when('/', {
controller: 'MainCtrl',
templateUrl: 'partials/pages/main.html'
})
.when('/devotion', {
controller: 'MainCtrl',
templateUrl: 'partials/pages/devotion.html'
})
.when('/results', {
controller: 'MainCtrl',
templateUrl: 'partials/pages/results.html'
})
.otherwise({redirectTo: '/'});
});
I get the following error:
TypeError: Cannot read property 'testy' of undefined

It is a cordova phonegap setup with basic routes. I am new to angular. I have looked over the internet and im having trouble setting up a basic service to hold all my data so i can access it from all my routes. Any help would be appreciated.
You will need to identify your services as a dependency of the controller.
The first step is to make sure you define the services before the controller.
then change the controller code so that it names the services as a dependency.
angular.module('Manalator.controllers', ['Manalator.services'])
.controller('MainCtrl', ['$scope', function ($scope, manaFactory) {
manaFactory.testString();
}]);
Hope this helps!
Hi I have following module, route and controller defined in one file called main.js
var mainApp = angular.module("mainApp", ["ngRoute", "ngResource", "ui"]).
config(function ($routeProvider) {
$routeProvider.
when('/addEmp', { controller: EmpCtrl, templateUrl: 'addEmp.html' }).
when('/addLoc', { controller: LocCtrl, templateUrl: 'newLocation.html' }).
otherwise({ redirectTo: '/' });
});
mainApp.factory("addEmp", ['$resource', function ($resource) {
return $resource('/api/addEmp/:id', { id: '#id' }, { update: { method: 'PUT' } });
}]);
mainApp.factory("addLoc", ['$resource', function ($resource) {
return $resource('/api/newLoc/:id', { id: '#id' }, { update: { method: 'PUT' } });
}]);
//Controllers
var EmpCtrl = function ($scope, $location, addEmp) {
//code here
};
var LocCtrl = function ($scope, $location, newLocation) {
//code here
};
What I am trying to do is organize this one file code into different files. I created script/controller folder where I want to have individual files for controller like
EmpCtrl.js and LocCtrl.js.
When I created the controller files and copied the controller code in it i get error of EmptCtrl and LocCtrl not defined.
Can you please tell me how I can set it up in different folders with appropriate path settings?
Thanks
try this
angular.module("mainApp", ["ngRoute", "ngResource", "ui"]).
config(function ($routeProvider) {
$routeProvider.
when('/addEmp', { controller: 'empCtrl', templateUrl: 'addEmp.html' }).
when('/addLoc', { controller: 'locCtrl', templateUrl: 'newLocation.html' }).
otherwise({ redirectTo: '/' });
});
//in empCtrl.js file
angular.module('mainApp').controller('empCtrl', ['$scope', '$location', 'addEmp',
function ($scope, $location, addEmp) {
//code here
}]);
// same for locCtrl
In your html make sure to include your mainApp.js file before you empCtrl and locCtrl scripts
the key is that you use string names to refer to your controller in your rout configs
{ controller: 'empCtrl' ... }
instead of
{ controller: EmpCtrl ... }
I would recommend that you use require.js to modularize your Angular project, you won't have to worry about order of script includes and it will result in a cleaner project
I want to show url as "www.test.com/!#" for that i am using $locationProvider.hashPrefix("!") ; but it shows url as "www.test.com/#!" . i want "!" before hash not after hash.
Thanks
var app = angular.module('app', []);
app.config(function ($routeProvider, $locationProvider) {
$locationProvider.html5Mode(false);
$locationProvider.hashPrefix("!");
$routeProvider.when('/', {
templateUrl: "app.html",
controller: "AppCtrl"
}
)
.when('/Program', {
templateUrl: "detail1.html",
controller: "Redirect"
})
.when('/Program/123456/channel/78458585',
{
templateUrl: "details.html",
controller: "Detail"
});
});
app.controller("AppCtrl", function ($scope) {
});
app.controller("Detail", function ($scope, $location) {
});
app.controller("Redirect", function ($scope, $location) {
$location.path("/Program/123456/channel/78458585")
});
If you want a ! in the URL before the fragment identifier begins, then you need to put it in the URL to start with and not try to do it with Angular.
http://www.example.com/#foo and http://www.example.com/#!foo are different parts of the same page.
But http://www.example.com/#foo and http://www.example.com/!#foo are different pages altogether.
