NgRoute not working - javascript

For some reason im not sure about my ngRoute here is not working properly. Please help me thankyou. Here is my cloud9 file where you can see live preiview and edit code. And here is my script.js:
var app = angular.module('ChattApp', ["firebase", "ngRoute"])
app.config(["$routeProvider", function($routeProvider){
$routeProvider
.when('/', {
templateUrl: 'HtmlFiles/login.html',
controller : 'LoginController.js'
})
.otherwise({
redirectTo: '/'
})
//Talk In Chat/Group Chat. I have to go to school now..
}]
)
app.factory("Auth", ["$firebaseAuth",
function($firebaseAuth) {
var ref = new Firebase("https://uniquecoders.firebaseio.com/");
return $firebaseAuth(ref);
}
]);

Remove app definition in all controller files.. as app is already defined in another script.. the cause is that the variable is being redefined for each loaded controller file..
please check http://www.w3schools.com/js/js_scope.asp for variable scope lifetimes

Controller inside the object for the ".when" method takes controller name which is registered via angular not a 'js' file containing the controller's code.
When you register the controller you use the method Controller(name, constructor). Then name you place as the first argument is the "name" of the controller that you are registering with angular.
controller : 'LoginController.js'
Should be:
controller : 'LoginController'

Search for "Route" on this page and then look at the controller object properties.

Angular $route change url based on route

I'm writing a simple product information management app using angular js. To keep my app as modular as possible i've split it into multiple modules with one module "pim" as startpoint. For each module I want to have a different route, so that it is easy to plug in a new module or remove it without having to maintain a huge route in the pim module config.
Currently I have two routes (the first route):
(function(){
angular
.module("pim")
.config(router)
function router($routeProvider){
$routeProvider
.when("/",{
templateUrl: "view/info.html",
controller: "pimController"
})
.when("/info",{
templateUrl: "view/info.html",
controller: "pimController"
})
.when("/alcohol",{
templateUrl: "view/alcohol.list.html",
controller: "alcoholController"
});
}
})();
The second route
(function(){
angular
.module("alcohol")
.config(router)
function router($routeProvider){
$routeProvider
.when("/alcohol/list",{
templateUrl: "view/alcohol.list.html",
controller: "alcoholController"
})
.when("/alcohol/info",{
templateUrl: "view/alcohol.info.html",
controller: "alcoholController"
});
}
})();
As you can see /alcohol has a templateUrl and a controller, the same as /alcohol/list, but i want to know if there is a simple (standard) way to change to another URL for example /alcohol/list, so that I do not have to repeat the templateUrl and controller and keep this information in the alcohol module, where it belongs.
For example
.when("/alcohol",{
routeTo: "/alcohol/list"
})
Thank you for your help
SOLVED
The option to redirect exists, did not look in the $routeProvider documentation well enough:
.when("/alcohol",{
redirectTo:"/alcohol/list"
});
The code above works
You can use $routeProvider's redirectTo route map.
.when("/alcohol", {
redirectTo: "/alcohol/list"
});

Angular ui-view (UI-Router) not rendering template - plunker included

Question Background:
I am using AngulaJS's UI Router for the first time to create two views within my app.
The Issue:
Plunker link: https://plnkr.co/edit/2XAKa6mDCUyzyOPz2CNK
I feel I'm missing something simple here but I cannot get any route to render the specified html templates set in the app.js.
Eventually I want the Update.html template to render when the submit fucntion of the home.html (search()) is clicked but first off I need to be able to actually render a single view which I currently cannot.
I would expect on-load for the route to render up the home.html page but it wont:
Any help sorting this will be much appreciated.
app.js:
angular
.module('app', [
'ui.router'
])
.config(['$urlRouterProvider', '$stateProvider', function($urlRouterProvider, $stateProvider) {
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('home', {
url: '/',
templateUrl: 'home.html',
controller: 'HomeController'
})
.state('update', {
url: '/update',
templateUrl: 'Update.html',
controller: 'UpdateController'
})
}])
Looking at your plunker briefly, it looks like your controller files are creating new angular apps with the same name. They were overriding each other so the .config() block didn't exist in the final app. I have updated the controller files in this plunker and it seems to be rendering the first ui view fine:
https://plnkr.co/edit/cdpWWOaBJWL3dONtIXzv?p=preview
Notice in the controller files, the angular.module('app') no longer has the second argument ['ui-bootstrap'] which was causing a new angular app to be created for each controller file. Check it out here in the angular docs.
Beware that using angular.module('myModule', []) will create the module myModule and overwrite any existing module named myModule. Use angular.module('myModule') to retrieve an existing module.
Hope this helps!

AngularJS ngRoute - Rendering template along with Angular Controller the $routeProvider is pointing

I'm rendering template using ngRoute - $routeProvider and I'm trying to render respective controller along with the template. $routeProvider is pointing to that controller and so it gives me an error controller is undefined because I think the App is trying to call the controller before it receives the template.
The templateCtr definition is in the separate JS file.
app.js
...
$routeProvider
.when('/template', {
templateUrl: '/template.html',
controller: 'templateCtr'
})
;
template.html
...
<script src="templateCtr.js"></script>
templateCtr.js
var myApp = angular.module('myApp'); //Getting module reference
myApp.controller('templateCtr', ['$scope', function($scope){
...
}]);
I also came across resolve property using which can load data to be used in controller before view is generated but for that too controller has to present in the memory.
Someone please point me to the correct direction. Thanks!

Angular UI-router, controller is undefined

I am kind of new to the AngularJS framework and I am trying to migrate my test project using the standard router to use the UI-router, but I get the following error:
Error: [ng:areq] Argument 'mainCtrl' is not a function, got undefined
What I have done so far is:
Controller:
// mainCtrl.js
angular.module("sm-web")
.controller('mainCtrl',['$scope',
function($scope) {
...
}]);
Router:
angular.module('sm-web', ['ui.router'])
.config(['$stateProvider', '$urlRouterProvider', function( $stateProvider, $urlRouterProvider ) {
$urlRouterProvider.otherwise('root');
$stateProvider
.state('root', {
url: '',
templateUrl: path + 'ng/sm/view/main.html',
controller: 'mainCtrl'
});
}]);
Index:
<body ng-controller="mainCtrl">
<main-menu></main-menu>
<div class="container">
<div ui-view></div>
</div>
</body>
This works when I use the standard router, but not with the UI-router. Does anyone have any idea of what I am doing wrong?
It seems you have an issue w/the order you declare things. For you to declare the module "sm-web" you need to do this:
angular.module('sm-web', ['ui.router']);
Note that the presence of that 2nd array argument is what tells Angular that you're declaring the module (eg. creating a new module). When you leave that 2nd argument out, you're retrieving the module you previously declared.
So with that in mind, look at how it all is coming together in your code:
To declare the controller, you retrieve the module "sm-web" (by leaving off the 2nd array arg).
When configuring the router states, you declare a new module "sm-web". But note that immediately after you declare this new module, you try to register a state with the controller named "mainCtrl" -- but that doesn't exist yet.
You need to create the module somewhere before doing all of the above. After creating the module, then register the controller on the module. Finally, with the controller defined, then you can register the state that uses the controller.
There's too many ways to solve this ordering problem, so I'm not going to suggest anything further. It depends on what files the code lives in and the order you load those files in index.html.
In order to avoid your problem change your code by the following code:
// mainCtrl.js
angular.module("sm-web")
.controller('mainCtrl',['$scope',
function($scope) {
...
}]);

$routeParams in a controller for index.html

I have an application that only uses an index with a controller main.js. I want the content to be defined by the URL, so I want to use $routeParams in the controller. My problem is that it turns up empty.
This is in my app.js
.config(function ($routeProvider) {
$routeProvider
.when('/:guid', {
templateUrl: '/index.html',
controller: 'MyCollectionUnitCtrl'
})
.otherwise({
redirectTo: '/'
});
});
The controller:
.controller('MyCollectionUnitCtrl',
function ($scope, $location, $routeParams) {
console.log($routeParams.guid); // Undefined
}
I've doubled checked that the module-names are the same.
The problem is that none of the code from the controller runs. I tested this by adding a console.log at the top. Index is not even a template, as I use no partials. I can't find anything about routing when only using one view, so here's where I'm stuck.
It doesn't work when I just define the controller with ng-controller neither.
Ideas? Something I'm missing? Is this a stupid question that's easily explained by documentation? I appreciate all comment, answers and feedback you can give me.
Thank you!
EDIT:
I've also tried to define ng-controller in the index.html, and then only have controller in the routingConfig, but that did not work either.
EDIT2: Plunker
Its hard to find out actual problem with your code snippet, but i think you are missing ngRoute module.
Add angular-route.js script in your html and add ngRoute dependency in your module.
