simple angularjs app view not loading - angularjs

I'm trying to get into angularJS by writing the most basic app. However I'm unable to get even this small amount of code working - the controller doesn't seem to be displaying any of the views. This is almost a direct copy from a popular angularjs video I saw online. I have a feeling its not something big, and my guess is that I possibly have something wrong with the ng-view.
Any insight on what I'm doing wrong would be helpful.
index.html
<!doctype html>
<html ng-app="fastsql">
<head>
</head>
<body>
<div class="well">
<div ng-view></div>
</div>
<script src="angular.min.js"></script>
<script src="fastsql.js"></script>
</body>
</html>
fastsql.js
// setup fastsql as angular app "module"
var fastsql = angular.module("fastsql", []);
// set routeProvider rules in .config()
fastsql.config(function($routeProvider) {
// set what views are displayed for each change in the URL.
$routeProvider
.when("/", { controller: 'loginCntl', templateURL: 'test.html' })
.otherwise({ redirectTo: '/' });
});
// controllers
fastsql.controller("loginCntl", function($scope) { $scope.message = "hey"; });

templateURL should have been templateUrl.

you need to pass an array into the config function, the name of the services to injected, and then the function in to which they are injected.
fastsql.config(["$routeProvider", function($routeProvider) {
// do your thing
}]);

Unable to load controller within $routeProvider in AngularJS

This is my very first AngularJs app and created it after going through many examples on the web but I am doing something wrong here. It is highly likely because files are stored in dedicated folders. The HomeView.html template gets loaded fine but the controller doesn't. I mean I cannot get greetingMessage printed in the template. All I see is {{ greetingMessage }} instead of "Welcome!". What am I missing?

</div>
HomeController.js
var module = angular.module('myApp', []);
module.controller('HomeController', [
'$scope',
function(
$scope
) {
$scope.greetingMessage = 'Welcome!';
}]);
The main reason is you haven't referred homeController.js on index.html, it should place right after index.js. This will not solve your issue. The other thing I'd like to mention is, you shouldn't be creating myApp module again while registering your controller with your myApp module. By declaring new module will flush out former registered component. So just use module getter like angular.module('myApp') and append further components to it.
<script src="components/home/HomeController.js">
Code
angular.module('myApp')
.controller('HomeController', [ '$scope',
function($scope) {
$scope.greetingMessage = 'Welcome!';
}
]);
You must be attach app file and next attache your controller file in your hoem page or master page.

Load views with AngularJS and Django

I'm trying to swap views when I click a link using AngularJS.
My index.html is something like that:
<head>
<script src="media/static/js/angular-route.js"></script>
<script src="media/static/js/angular.js"></script>
<script src="media/static/js/app.js"></script>
<script src="media/static/js/controller.js"></script>
</head>
<body ng-app="demoApp">
View1
View2
<div ng-view></div>
</body>
My app.js is something like that:
angular.module('demoApp', ['ngRoute']).
config(['$routeProvider', function( $routeProvider) {
// Define routes
$routeProvider
.when('/view1',
{ templateUrl: 'templates/view1.html'})
.when('/view2',
{ templateUrl: 'templates/view2.html'})
.otherwise({redirectTo: 'view1'});
}]);
I'm completely new with Angular and I'm going crazy trying that.
Thanks in advance.
Sometime ago, I wrote a snnipet for this, you can found it here. Please give a feedback if it's useful and is still working.

Using angular ui.router how to start in a standard html angular page and than move forward to one with ui.router template inside a folder?

I have a standard angular page that is not associated with any ui.router functionality(index.html). From that page I click a link that triggers an angular call and than after some operation the flow needs to be redirected to a page inside a folder that is using angular-ui.route template.
I have created a plunker that represents this:
http://plnkr.co/edit/7UQTlMRQBMXGaRdHlPfs?p=preview (current plunker is working but there's a loop on first page trying to call default state created with $urlRouterProvider.otherwise('events');)
index.html

console.log('EventsController');
}]);
})();
I have created a plunker that represents this:
http://plnkr.co/edit/7UQTlMRQBMXGaRdHlPfs?p=preview
I have tried different ways of moving from the first non ui.router page but none worked so far.
What's the best way of doing this?
Firstly , do not inject $state as dependency in the LoginController as the view related to this controller isn't an UI route. Adding the $state dependency causes the loop that you are seeing in your example as UI-Router then considers this view a route. As no state matches this route , it tries to load the default state , whose template has a relative URL , which then looks it up inside wrong directory of Plunkr , which causes 404 error.
Secondly , the URL to redirect should via location.href should have a hash otherwise it will also give 404
The code for the LoginController
app.controller('LoginController', ['$scope', '$window',
function($scope, $window) {
$scope.goToEvents = function() {
//Do Something
$window.location.href = 'manage/home.html#/events';
};
}
]);

AngularJS routeprovider.config not called

I'm trying to build a simple AngularApp Here. I'm trying to add routeProvider and use config for the same. But the page never worked as expected. When I tried using fireBug in firefox, I found that the function present in the config, was never invoked. So, the code inside it remains untouched. (I was able to confirm that with breakpoints).
I believe that I'm missing something trivial here. Please help me figure it out.

sampleApp.controller('HomeCtrl', function($scope) {
console.log('inside Hc');
});
sampleApp.controller('ContactCtrl', function($scope) {
console.log('inside Cc');
});
navbar.js
var navBarModule = angular.module('navbar', []);
navBarModule.directive('navBar', function() {
return {
scope: {},
templateUrl: 'templates/navbar.html'
};
});
EDIT: I had two ng-app in the source. I removed the navBar, and now things start to work fine. Can someone explain to me why this behaviour is seen? Both modules are independent of each other.
You don't inject the ng route module.It should be
var sampleApp = angular.module('kscapp',['ngRoute']);
You are using different versions for Angular.min.js and Angular-route.min.js.
update your angular-route from 1.2.9 to 1.3.8
Also inject 'ngRoute' to kscapp module.
You can only use 'ng-app' once in your application.
Concider moving your ng-app="kscapp" up to the html tag, and update kscapp to:
var sampleApp = angular.module('kscapp',['ngRoute', 'navbar']);
For more on ngApp, read ngApp API.

AngularJS routing keeps redirecting back to itself like it's in a loop

I have
<!DOCTYPE html>
<html lang="en" data-ng-app="myCustomApp">
<body>
<div id="body">
<div ng-view></div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js" type="text/javascript"></script>
<script src="/Js/app.js"></script>
<script src="/Js/controllers/controllers.js"></script>
</body>
</html>
With the following
app.controller('SearchController', function ($scope) {
init();
function init() {
alert("called");
}
});
and the app declared like below:
var app = angular.module('myCustomApp', []);
app.config(function($routeProvider) {
$routeProvider
.when('/search',
{
controller: 'SearchController',
templateUrl: '/js/partials/Search.html'
})
.otherwise({ redirectTo: '/search' });
});
The problem is that the page when browsing to the following it keeps refreshing the page like it's in a loop. Any ideas?
/#/search
var app = angular.module('myCustomApp', ['ngRoute']);
Routing is not native in angular you need to add it in as a module.
https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.15/angular-route.js
This is the CDN for the script for it. I'd really suggest having a look at ui-router works very similarly but uses state or states to manage either the view or sections of the view.
https://github.com/angular-ui/ui-router
The documentation is really good and there are some great examples around.
