I'm following the video tutorials on egghead.io but while trying to follow his example when he created a factory (see video here) I keep getting "angular is not defined" Reference Error but I have included the angular script
This is my html page:
<!DOCTYPE html>
<html>
<head>
<title>Prototype</title>
<link rel="stylesheet" type="text/css" href="foundation.min.css">
<script type="text/javascript" src="main.js"></script>
</head>
<body>
<div data-ng-app="">
<div data-ng-controller="FirstController">
<input type="text" data-ng-model="data.message">
<h1>{{ data.message }}</h1>
</div>
<div data-ng-controller="SecondController">
<input type="text" data-ng-model="data.message">
<h1>{{ data.message }}</h1>
</div>
</div>
<script type="text/javascript" src="angular.min.js"></script>
</body>
</html>
and this is my javascript file "main.js":
//Services
// step 1 create an app
var myApp = angular.module('Data', []).
// tep 2 create factory
// Service name, function
myApp.factory('Data', function(){
return { message: "I'm Data from a Service" }
});
//Controllers
function FirstController($scope, Data){
$scope.data = Data;
}
function SecondController($scope){
}
I have read a few posts where similar happen (here) and please correct me if I'm wrong but I think it is to do with Boot strapping andI have tried manually bootstrapping using angular.bootstrap(document, ['Data']); but with no success, still get same error.
But What I want to know is, Why this works for so many examples online, like the egghead video series, but I have issues as I believe I have followed his video very closely. is it a change in angular in recent versions?
You have to put your script tag after the one that references Angular. Move it out of the head:
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="main.js"></script>
The way you've set it up now, your script runs before Angular is loaded on the page.
You have not placed the script tags for angular js
you can do so by using cdn or downloading the angularjs for your project and then referencing it
after this you have to add your own java script in your case main.js
that should do
I had the same problem as deke. I forgot to include the most important script: angular.js :)
<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>

I'm new to Angular JS , trying to develop little application on Calculations .
My Code is as follows"
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
<script src="scripts/angular.js"></script>
<script src="scripts/angular-route.js"></script>
</head>
<body>
<div ng-app="Calculator">
<div ng-controller="Operations">
<div>
Number 1 : <input type="number" ng-model="Number1" />
Number 2: <input type="number" ng-model="Number2" />
<p>
The addition of above two numbers is {{Number1+Number2}}
</p>
</div>
</div>
</div>
<script>
var module = angular.module('Calculator', []);
module.controller('Operations', function ($scope) {
$scope.Number1 = 1;
$scope.Number2 = 10;
});
</script>
</body>
</html>
I have the Javascripts files available in My project, When I run the app, the browser console indicates that the JS are not being loaded. Don't know why !
The Expression {{Number1+Number2}} is the same in browser . It is not executing the expression
The Browser console has following errors:
Failed to load resource:"Path to the Script file" the server responded with a
status of 404 (Not Found)
Failed to load resource:"Path to the Script file" the server responded with a
status of 404 (Not Found)
Uncaught ReferenceError: angular is not defined
<script src="scripts/angular.js"></script>
<script src="scripts/angular-route.js"></script>
You are not loading angular.js and angular-route.js properly, check your paths.
Your project structure has to look like
index.html
scripts
|---angular.js
|---angular-route.js
If you use
<script src="scripts/angular.js"></script>
<script src="scripts/angular-route.js"></script>
<script src="/scripts/angular.js"></script>
<script src="/scripts/angular-route.js"></script>
Please note , you might need to disable adblocks if necessary.
Drag and drop in visual studio doesn't work if you are using HTML pages but it does work for mvc ,asp.netwebforms.
I figured this after one hour
I am presenting my issue in a simple manner as below
There is a index.html as below
Index.html
<script src="js/libs/jquery/jquery.js"></script> <!--JQuery library-->
<script src="js/libs/angularjs/angular.js"></script>
<script src="js/libs/angularjs/app.js"></script>
{{title}}<br>
<ng-include src="'document.html'"></ng-include><br>
newPage
My app.js is as follows
angular.module('myApp',[])
.controller('myController',function($scope){
//array to store the items
$scope.title = "This is a test message";
$scope.secondPage = "this is the second page"
});
The document.html is as follows
<div ng-controller="myController">
{{secondPage}}
</div>
I need to run the document.html in a new page, but obviously since the document.html does not have the import script of angular.js,app.js it won't render. But if i do put the script statements in document.html there will be multiple imports in the index.html. How do i solve this issue ?
Require.js would not solve this issue.
One bad way to solve the issue would be import the document.html as text and remove the importing statements.(bad bad way !!)
Create a new page for the new window opener similar to index.html
So your code will be like:
Index.html
<script src="js/libs/jquery/jquery.js"></script> <!--JQuery library-->
<script src="js/libs/angularjs/angular.js"></script>
<script src="js/libs/angularjs/app.js"></script>
{{title}}<br>
<ng-include src="'document.html'"></ng-include><br>
newPage
documentwindow.html
<script src="js/libs/jquery/jquery.js"></script> <!--JQuery library-->
<script src="js/libs/angularjs/angular.js"></script>
<script src="js/libs/angularjs/app.js"></script>
{{title}}<br>
<ng-include src="'document.html'"></ng-include><br>
Hope this works for you
I am trying to play audio using AngualarJs
My HTML CODE:
<!doctype HTML>
<html>
<head>
</head>
<body ng-app="test" ng-controller="audioTest">
<button ng-click="playSound()"></button>
<script src="javascripts/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"> </script>
<script src="javascripts/angular.audio.js"></script>
<script src="app.js"></script>
</body>
</html>
My app.js Code:
var app = angular.module("test",['ngAudio']);
var audio = app.controller("audioTest",function($scope,ngAudio){
$scope.playSound = function(){
$scope.audio = ngAudio.load("abc.wav");
$scope.audio.play();
}
});
While i load page i got error in console which lead me to
Error Details
The error you're reporting is due to an error resolving angular.audio.js script that can't be found by the name javascripts/angular.audio.js
I made a working fiddle: http://jsfiddle.net/en8x1nny/
This fiddle imports the script that the original demo from ngAudio is using.
The full path for that script is: http://danielstern.github.io/ngAudio/angular.audio.js.
You can download it and add it to your javascripts directory. Be sure not to use it by the URL mentioned above because github is not a CDN intended to serve scripts.
If you previously installed ngAudio by bower, the script should be in:
your_project_path/bower_components/angular-audio/app/angular.audio.js
I'm trying to learn Angular and attempting to write my first controller outside of a web-based tutorial. I keep getting the error in the title in the JS console and can't figure out what's going on. The link takes me to a page referencing the need to include ngRoute, which I've done according to the API. Surely I'm missing something but I can't see what it is. Any help would be greatly appreciated, thanks!
index.html
<DOCTYPE html>
<html ng-app="myApp">
<head>
<title>First Angular Project</title>
<link href="bootstrap.min.css" rel="stylesheet">

<div class="container" ng-controller="FirstController">
Did the controller load?
</div>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="angular-route.min.js"></script>
<script type="text/javascript" src="app.js"></script>

</html>
app.js
(function () {
var app = angular.module('myApp', ['ngRoute']);
app.controller('FirstController', function(){
console.log("FirstController loaded");
});
})
Your issue is that you forgot to invoke the iife which registers module and controller.
(function () {
var app = angular.module('myApp', ['ngRoute']);
app.controller('FirstController', function(){
console.log("FirstController loaded");
});
})();//<-- here
Link (in the error) talks about ngRoute as a hint only for one of the reasons your module might not have been available/instantiated when angular ng-app directive tried to bootstrap it. But in your case it does not even exists due to your failure to invoke the anonymous function as IIFE.
I am trying to set up a backbone driven web application but cannot get Backbone to load correctly. I get two errors when I load the required files:
-Uncaught ReferenceError: Backbone is not defined test.html: 17
-Uncaught TypeError: Cannot read property 'each' of undefined backbone.min.js: 1
I have tried multiple sources for the backbone, underscore and jquery files and am still having the same errors. Any help would be appreciated. Thanks.
<html>
<head>
<title></title>
</head>
<body>
<script type="text/javascript" src="backbone-min.js"></script>
<script "text/javascript" src="jquery-2.1.1.js"></script>
<script "text/javascript" src="underscore-min.js"></script>
<script>
Person = Backbone.Model.extend({
initialize: function(){
console.log("hello world");
}
});
var person = new Person();
</script>
</body>
</html>
You must include your libraries properly to fulfill missing dependencies:
<script src="jquery-2.1.1.min.js"></script>
<script src="underscore-min.js"></script>
<script src="backbone-min.js"></script>
It's important to include underscore before you include backbone because underscore is a dependency of backbone.
include Backbone.js and Underscore.js(a dependency of Backbone.js)
Related introduction on backbone.
This is a common mistake with common libraries such as jQuery, wherea libraries like Bootstrap rely on components provided by an external provider.
A quick glance and I can't see anything immediately wrong, although you are missing the 'type' on your second and third script tags. When you run the page in browser, are there any errors logged out to the console, can you see the libraries being loaded fine in the network viewer too? My immediate hunch would be the source paths are wrong and so the libraries aren't being loaded.
Dependencies!!! The order matters, backbone needs jQuery and underscore
