Angular controller not working - javascript

I'm newbie to angular
My angular controller is:
var chatApp = angular.module('chatApp.controllers', []);
chatApp.controller('loginController', ['$scope', function($scope) {
$scope.user_name="name";
$scope.user_password="name";
}]);
the app.js is:
'use strict';
angular.module('chatApp', [
'ui.router',
'chatApp.filters',
'chatApp.services',
'chatApp.directives',
'chatApp.controllers'
]).config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('login', {
url: "/login",
templateUrl: "partials/login.html",
controller : "loginController"
})
});
login.html is:
<div>
<div id="wrapper">
<form name="login-form" class="login-form" action="" method="post">
<div class="header">
<h1>Login Form</h1>
</div>
<div class="content">
<input name="username" type="text" class="input username" placeholder="{{user_name}}" />
<div class="user-icon"></div>
<input name="password" type="password" class="input password" placeholder="{{user_password}}" />
<div class="pass-icon"></div>
</div>
</form>
</div>
I've used stateprovider for routing.
But, it's not showing anything in placeholder. What is the reason?

Solved the problem using ng-model instead of {{}}.
<div class="content">
<input name="username" type="text" class="input username" placeholder="username" ng-model="user_name" />
<div class="user-icon"></div>
<input name="password" type="password" class="input password" placeholder="password" ng-model="user_password"/>
<div class="pass-icon"></div>
</div>

This works for me if I say ng-controller = "loginController" in the html-
<div ng-controller = 'loginController'>
<div id="wrapper">
<form name="login-form" class="login-form" action="" method="post">
<div class="header">
<h1>Login Form</h1>
</div>
<div class="content">
<input name="username" type="text" class="input username" placeholder="{{user_name}}" />
<div class="user-icon"></div>
<input name="password" type="password" class="input password" placeholder="{{user_password}}" />
<div class="pass-icon"></div>
</div>
</div>
Here's a JSBin with it working: http://jsbin.com/aDuJIku/265/edit?html,js,output
This solution doesn't include ui-router, but it should work with it.

Try this:
var chatApp = angular.module('chatApp.controllers', []);
chatApp.controller('loginController', ['$scope','$timeout', function($scope,$timeout) {
$timeout(function(){
$scope.user_name="name";
$scope.user_password="name";
},100);
}]);

you just have to change to RouteProvider, In your case you just do:
angular.module('chatApp', [ 'ngRoute' 'ui.router','chatApp.filters','chatApp.services', 'chatApp.directives', 'chatApp.controllers'])
.config(function($routeProvider) {
$routeProvider.when('/login', { templateUrl: "partials/login.html", controller: "loginController" })
});
please make sure that you have angular-route js included.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular-route.js"></script>
Hope this help you! ;)
Here's some examples for you this

Below mentioned code works.
Note: If somebody tries to run this code in preview its not going to work. JS and HTML code needs to be copied in separate file and use the names mentioned.
var myContrlApp = angular.module('ContrlApp', []);
myContrlApp.controller('MainController', function ($scope) {
var person = {
firstName: "Keith",
lastName: "Jackson",
};
$scope.message = "Welcome, Angular !";
$scope.person = person;
});
<html ng-app="ContrlApp">
<head>
<script type="text/javascript" src="Scripts/angular.js"></script>
<script type="text/javascript" src="Scripts/angular-route.js"></script>
<script type="text/javascript" src="Scripts/script.js"></script>
<!--<link rel="stylesheet" href="style.css" />-->
<title>Angular JS Tryout</title>
</head>
<body ng-controller="MainController">
<div>
<h1>{{message}}</h1>
<div>
<div>First name: {{person.firstName}}</div>
<div>Last name: {{person.lastName}}</div>
</div>
</div>
</body>
</html>

AngularJS sample code showing code not data

I'm trying to follow a tutorial for MEAN stack starting with Angular and even the provided sample code won't work. The code shows instead of the data, eg. "{{created_buy}}" instead of "David". I'm new to Angular so I feel like I might be missing something obvious...
main.html:
<!--main.html-->
<html>
<head>
<title>Chirp</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
<script src="javascripts/chirpApp.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<link rel="stylesheet" href="stylesheets/style.css">
</head>
<body ng-app="chirpApp">
<div id='main' class="container" ng-controller="mainController">
<div class="col-md-offset-2 col-md-8">
<div class="clearfix">
<form ng-Submit="post()">
<input required type="text" class="form-control" placeholder="Your name" ng-model="newPost.created_by" />
<textarea required class="form-control" maxlength="200" rows="3" placeholder="Say something" ng-model="newPost.text"></textarea>
<input class="btn submit-btn pull-right" type="submit" value="Chirp!" />
</form>
<div id="post-stream">
<h4>Chirp Feed</h4>
<div class="post" ng-repeat="post in posts | orderBy:'created_at':true" ng-class-odd="'odd'" ng-class-even="'even'">
<p>{{post.text}}</p>
<small>Posted by #{{post.created_by}}</small>
<small class="pull-right">{{post.created_at | date:"h:mma 'on' MMM d, y"}}</small>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
app.js:
//chirpApp.js
var app = angular.module('chirpApp', []);
app.controller('mainController', function($scope){
$scope.posts = [];
$scope.newPost = {created_by: '', text: '', created_at: ''};
$scope.post = function(){
$scope.newPost.created_at = Date.now();
$scope.posts.push($scope.newPost);
$scope.newPost = {created_by: '', text: '', created_at: ''};
};
});
You need to refer the correct js file
<script src="javascripts/chirpApp.js"></script>
but you have mentioned app.js, so it should be
<script src="javascripts/app.js"></script>

loginApp.controller('loginCtrl',['$scope',function($scope){
console.log("controller loaded");
alert("controller loaded");
$scope.login=function(){
console.log("inside loginCtrl : login function");

You have missed to add ng-view directive on your page, so that will load the template & controller configured on $routeProvider inside ng-view directive element.
<div ng-view></div>

Assigning controller to a form template with $routeProvider in AngularJS

I'm building my first angular app, starting with a simple login form. I load the form from a partial, however when I try submitting the form, nothing is logged to the console, i.e. I assume my authenticate() method is not called. I have the following definition for my app.js:
'use strict';
angular.module('spForums',[])
.config(['$routeProvider','$locationProvider',function($routeProvider,$locationProvider) {
$routeProvider.when('/login', {
templateUrl: 'static/partials/login.html',
controller: loginController,
controllerAs: 'login'
});
$locationProvider.html5Mode(true);
}])
And here's the controller, defined in a separate controller.js:
'use strict';
function loginController() {
this.email = '';
this.password = '';
this.authenticate = function () {
console.log(this.email);
console.log(this.password);
};
};
Here's the partial, login.html:
<form class="form-signin" novalidate ng-submit="login.authenticate()">
<h2 class="form-signin-heading">Please sign in</h2>
<label for="inputEmail" class="sr-only">Email address</label>
<input type="email" id="inputEmail" class="form-control" placeholder="Email address" required autofocus ng-model="login.email">
<label for="inputPassword" class="sr-only">Password</label>
<input type="password" ng-model="login.password" id="inputPassword" class="form-control" placeholder="Password" required>
<div class="checkbox">
<label>
<input type="checkbox" value="remember-me"> Remember me
</label>
</div>
<input class="btn btn-primary" type="submit" value="Sign-in">
</form>
And here's the relevant part of index.html, or in my case, forum.html that includes the partial:
<!doctype html>
<html lang="en" ng-app="spForums">
<head>
<script type="text/javascript" src="/static/js/lib/angular.min.js"></script>
<script type="text/javascript" src="/static/js/lib/angular-resource.min.js"></script>
</head>
<body>
<div class="container" id="forumcontainer" ng-view>
</div> <!-- /container -->
<script type="text/javascript" src="/static/js/app.js"></script>
<script type="text/javascript" src="/static/js/controller.js"></script>
</body>
</html>
I'd like to end this by saying I'm new to Angular-JS. As in I just saw a bunch of tutorials and this is my first app. Please tell me where I'm wrong.
EDIT:- I'm using Angular-JS version 1.0.7.
You need to include ngRoute module into your application, it's not shipped by default:
<head>
<script>document.write('<base href="' + document.location + '" />');</script>
<script src="/static/js/lib/angular.min.js"></script>
<script src="/static/js/lib/angular-route.min.js"></script>
<script src="/static/js/lib/angular-resource.min.js"></script>
</head>
Note, that you also need to define base href tag, since you are using HTML5 mode.
Then define module with necessary dependencies:
angular.module('spForums', ['ngRoute', 'ngResource'])

Scripts don't load: Using AngularJS with JSON (Firebase)

I've tried to build an application that let's you input data into several fields, uses AngularJS to put data into a Firebase JSON, and outputs that data into nicely laid out "cards".
Initially I could input and output data, but as soon as I hooked it up to AngularJS and Firebase I just got '{{ 1 + 2 }}' instead of '3' in my browser.
I'm running this code on my webserver, I hope you can help me figure out what the problem is – the page is pretty much blank. Everything that depends on Angular isn't showing up.

Thank you so much <3
you have included venues.js instead of repertoire-venues.js in the index page and there is a comma missing on line 14 in repertoire-venues.js

AngularJS data binding Form properties in template

I have a simple AngularJS app with a single form that has 2 fields on it. I am trying to read the values entered in those 2 fields from my controller but for some reason I am always getting undefined. I have triple checked my code but can't find anything in it, so I hope someone can please help and tell me what I am doing wrong and how to fix it.
Note: I am using latest AngularJS release 1.2
app.js
'use strict';
var myApp = angular.module('myApp', ['ngRoute','ngSanitize']);
myApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/index',
{ templateUrl: 'templates/common/index.html',
controller: 'IndexController'
}).
when('/editcontact',
{ templateUrl: 'templates/contacts/editContact.html',
controller: 'editContactController'
}).
otherwise({redirectTo: '/index'});
}]);
index.html
<!DOCTYPE html>
<html lang="en" ng-app="myApp">

editContactController
myApp.controller('editContactController',
function editContactController($scope){
$scope.saveContact = function(contacts, editContactForm){
if(editContactForm.$valid){
console.log(contacts.name);
}
};
});
You have a typo. ng-modal should be ng-model
<input id="name" type="text" placeholder=Name..." ng-modal="contacts.name">
<input id="phone" type="text" placeholder="Phone" ng-modal="contacts.phone">
should be
<input id="name" type="text" placeholder=Name..." ng-model="contacts.name">
<input id="phone" type="text" placeholder="Phone" ng-model="contacts.phone">
