I downloaded the seed project from git. Basically, changed the code in following three files -
app.js
angular.module('app', []);
index.html
<!DOCTYPE html>
<html ng-app="app">
<head lang="en">
<meta charset="UTF-8">
<title>AngularJS Tutorial</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
</head>
<body ng-controller="MessageController">
<div class="container">
<h1>{{title}}</h1>
</div>
</body>
</html>
MessageController.js
angular.module('app').controller("MessageController",function(){
alert("inside message controller");
var vm = this;
vm.title = 'AngularJS Tutorial Example';
});
When I run http://localhost:8000/app/index.html, it displays {{title}} and not the value inside controller.
I am new bie in angular and trying to learn but unable to figure out whats wrong here.
You appear to have two different things happening.
First you appear to have missed adding your javascript dependencies to your html file.
<head lang="en">
<meta charset="UTF-8">
<title>AngularJS Tutorial</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<script src="app.js"></script>
<script src="MessageController.js"></script>
</head>
An additional note
Because you are using multiple files (which is fine), make sure you include the app.js file before the MyController.js file.
You also need to correctly access the scope. Even if you add the javascript dependencies you will get a blank page if not bound correctly.
Because you are using var vm = this; format you need to be sure to use the control as annotation
<body ng-controller="MessageController as myctrl">
<div class="container">
<h1>{{myctrl.title}}</h1>
</div>
</body>
Working Plunker Example
Another options is to directly extend $scope in your controller. You could then just have {{title}} on your page and it should bind correctly.
angular.module('app').controller("MessageController",['$scope',function($scope){
alert("inside message controller");
$scope.title = 'AngularJS Tutorial Example';
}]);
var yourapp = angular.module('app', []);
yourapp .controller('MessageController', function ($scope) {
alert("inside message controller");
$scope.title = 'AngularJS Tutorial Example';
});

Newbie to AngularJS. Trying to display a message from controller onto the html page but it does not show. I'm using AngularJS version 1.6.0 and I binded the controller to the body tag. What am I missing?
/// HTML
<!DOCTYPE html>
<html ng-app="app">
<head>
<script data-require="angular.js#*" data-semver="4.0.0"
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.10/angular.min.js">
</script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
// script.js file contents
var app = angular.module('app', []);
app.MainController('MainController', function($scope) {
$scope.message = "Hello, Angular!";
});
Thank you.
Since you are using the version 1.6 , declaration of global controller is not supported, you need to have a module as well.
DEMO
var app = angular.module('testApp',[])
app.controller('MainController',function($scope) {
$scope.message = "Hello, Angular!";
});
<!DOCTYPE html>
<html ng-app="testApp">
<head>
<script data-require="angular.js#*" data-semver="4.0.0"
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.10/angular.min.js">
</script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
do you need to pass the name of your app on the ng-app tag.
Like this:
<html ng-app="your-app">
So Angular understand where it comes.
So, an advice to you is using the controllerAs syntax over the classic controller with $scope syntax.
Like this:
JS file:
var app = angular.module('testApp',[])
app.controller('MainController',function($scope) {
var vm = this; // view model
vm.message = "Hello, Angular!";
});
HTML file:
<body ng-controller="MainController as mainCtrl">
<!-- or any other name, your choice -->
<h1>{{mainCtrl.message}}</h1>
</body>
Why?: Controllers are constructed, "newed" up, and provide a single
new instance, and the controllerAs syntax is closer to that of a
JavaScript constructor than the classic $scope syntax.
Why?: It promotes the use of binding to a "dotted" object in the View
(e.g. customer.name instead of name), which is more contextual, easier
to read, and avoids any reference issues that may occur without
"dotting".
Why?: Helps avoid using $parent calls in Views with nested controllers

I hope this helps you
I have come across a lot of similar issues here on SF and did everything as expected. Yet, I can't seem to get this simple Angular app working. Console throws up this exception
angular.min.js:6 Uncaught Error: [$injector:modulerr]
AngularJS site docs gave some suggestions which I followed. Yet, I still get that same exception. Here is my code.
<!DOCTYPE html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="utf-8">
<title>Dead Simple Proj</title>
<link rel="stylesheet" href="content/css/styles.css">
<script scr="app\app.js"></script>
<script src="app\lib\angular.min.js"></script>
</head>
<body>
<div ng-controller="GreetingController">
{{ greeting }}
</div>
</body>
</html>
I have this in the App.js
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});
I double checked file paths and other possibly obvious mistakes, but no joy.
I am definitely missing out something here? Thanks.
Your paths referencing the libraries and the app.js are wrong and in the wrong order . You should load the angular reference first and then the relative js referencing the module.
Change
From
<script scr="app\app.js"></script>
<script src="app\lib\angular.min.js"></script>
To
<script src="app/lib/angular.min.js"></script>
<script scr="app/app.js"></script>
DEMO
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});

I dont think you added your angular files properly. I made a plunker out of your code and it worked. you can cross check with my code.
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});

<script src="script.js"></script>

APP.JS: ui bootstrap in js file . u can send the correct answer or code. i have tried but not come the popup.
this is script of index.html
var app=angular.module('myapp', ['ui.bootstrap']);
app.controller('Controller',['$scope', '$modal',function($scope,$modal){
$scope.create=function(){
var modalInstance=$modal.open({
templateUrl:'views/prakash.html',
});
}
}]);
index.html and app.js .
pop up is not coming if the swathi is clicked.
Are you sure the templateUrl you have given that is correct or the html file is available?
Or make sure you have initialized all the required dependent modules like ui-bootstrap-tpls-0.12.1.js
I have created a plunkr for your code and that is working.
var app=angular.module('myapp', ['ui.bootstrap']);
app.controller('Controller',['$scope', '$modal',function($scope,$modal){
$scope.create=function(){
var modalInstance=$modal.open({
templateUrl:'mypage.html',
});
}
}]);
See the plunkr here-
http://plnkr.co/edit/GRgjv8fyquOQirXwWaWQ?p=preview
You need to include the -tpls.js file aswell, that file will make your own templates go into $templates.cache so you can use your own.
I can't see that you've installed the tpls file.
Also shouldn't it be $uibModal instead of $modal?like so
var app=angular.module('myapp', ['ui.bootstrap']);
app.controller('Controller',['$scope', '$uibModal', function($scope, $uibModal) {
$scope.create=function(){
var modalInstance=$modal.open({
templateUrl:'views/prakash.html',
});
}
}]);

I am not able to figure out why angular variables are getting displayed as normal text instead of its assigned value. kindly help...
It looks like you are missing a link to your app.js file.
Just a tip when referencing your .js files, make sure you reference any javascript which uses Angular AFTER the line where you reference angular.js
So your references should look something like this:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<script src="app.js"></script> <!-- this is the one you are missing -->
Please, plunkr
It works
<h1>{{main.title }}</h1>
<div ng-controller='SubController as sub'>
<h2>{{sub.title}}</h2>
<p>If we were not using the <strong>ControllerAs</strong> syntax we would have a problem using title twice!</p>
</div>

Angularjs Uncaught Error: [$injector:modulerr] when migrating to V1.3

Closed 7 years ago.
This whole app should consist of an h1 element that says 'Adrian' and a paragraph that says 'He lives in Orlando'. I can't figure out what's wrong with my code. BTW, I already know that this isn't the best design pattern for Angular, but I just wanted something quick to get my feet wet with the framework.
<!doctype html>
<html lang="en" ng-app>
<head>
<meta charset="utf-8">
<title>Angular Demo</title>
<script src="angular.min.js"></script>
</head>
<body>
<div ng-controller="MyController">
<h1>{{person.firstName}}</h1>
<p>He lives in {{person.city}}</p>
</div>
<script>
function MyController($scope) {
$scope.person = {
'firstName': 'Adrian',
'city': 'Orlando'
}
}
</script>
</body>
</html>
You are not making Angular aware of your MyController function:
<!doctype html>
<!-- tell Angular what module to use -->
<html lang="en" ng-app="app">
<head>
<meta charset="utf-8">
<title>Angular Demo</title>
<script src="angular.min.js"></script>
</head>
<body>
<div ng-controller="MyController">
<h1>{{person.firstName}}</h1>
<p>He lives in {{person.city}}</p>
</div>
<script>
angular
// Define our module
.module('app', [])
// Define our controller
.controller('MyController', function MyController($scope) {
$scope.person = {
'firstName': 'Adrian',
'city': 'Orlando'
}
});
</script>
</body>
</html>
Get in the habit of assigning app names and controllers to the apps, here:
http://plnkr.co/edit/gfWh6fqWeni8s8M0iG1B?p=preview
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.person = {
'firstName': 'Adrian',
'city': 'Orlando'
}
});
</script>
I am not even trying to be a patronizing ass, but check the tutorial here. It will take you a couple of hours. Then head over to Jenkov's "complete" tutorial.
Your code works fine. I believe your angular source file is the issue try switching it to a CDN src or double check your path
