I am learning Angularjs and Restangular. I am following this page http://www.ng-newsletter.com/posts/restangular.html
== app.js==
angular.module('app', ['restangular']);
angular.module('app')
.controller('TestCtrl', ['$scope','Restangular',
function($scope,Restangular) {
this.product="gem";
}]);
== index.html ==
<!DOCTYPE html>
<html ng-app="app">
<head>
<script type="text/javascript" src="js/angular.min.js"></script>
<script type="text/javascript" src="js/restangular.min.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</head>
<body>
<div ng-controller="TestCtrl as test">
{{test.product}}
</div>
</body>
</html>
When i open index.html, it just opens {{test.product}}. But when i remove restangular references from app.js, it works fine. Paths to .js files are correct.
Please help me in getting this sorted.
==Solution==
This stackoverflow answer told me that i should NOT be using minified version of angular.js as it doesn't show error in detail. I was getting this error:
Error: Failed to instantiate module restangular due to: '_' is
undefined
From this answer i came to know that i was missing underscore/lodash which is a dependency of restangular. I included lodash in my html and everything worked fine then.

I am new to use angular.js.
I want to use gauge module ,but after i finish my html following Angular Gauge Document,it's not working(browser shows nothing).
I guess the problem is i didnt make the module work.
Can anybody tell me what is wrong with my code.
<!DOCTYPE HTML>
<html>
<body ng-app = "myApp">
<ng-gauge size="150" type="full" thick="5"
min="0" max="120" value="68.2"
cap="round" label="Speed" append="mph"
foreground-color="#ffcc66" background-color="#EEE">
</ng-gauge>
</body>
<script src="http://cdn.static.runoob.com/libs/angular.js/1.6.4/angular.min.js"></script>
<script src="node_modules/angular/angular.min.js"></script>
<script src="node_modules/angular-gauge/dist/angularjs-gauge.min.js"></script>
<script>
angular.module('myApp', ['angularjs-gauge']);
</script>
</html>
Plus, in the document installation part,it says:
As soon as you've got all the files downloaded and included in your page you just need to declare a dependency on the chart.js module:
i didnt use chart.js module in my project,so which chart.js file this guide refer to ?
You need to include the script tags inside the body tag, also you included the angular.min.js twice.

I am following the phoneCat tutorial[https://docs.angularjs.org/tutorial/] and decide to create a similar structured app. but I keep getting $injector:modulerr Error when I try to include a module I created.
files are arranged like this
The way I started my app is use npm package http-sever with command http-server ...\app.
Another thing I noticed is that if I use http-server command directly(rather than npm start suggested in tutorial) to start app in the app folder it also gives me error message. I am now pretty confused about this.
This is my app.module.js
'use strict';
angular.module('dota2Hero', [
'ngRoute',
'core'
]);
If I remove 'core' from dependency array, the code compiles.
Here is my index.html
<!doctype html>
<html lang="en" ng-app="dota2Hero">
<head>
<meta charset="utf-8">
<title>Dota2 Database</title>
<script src="//code.angularjs.org/1.6.1/angular.min.js"></script>
<script src="//code.angularjs.org/1.6.1/angular-route.min.js"></script>
<script src="core/hero/hero.module.js"></script>
<script src="core/core.module.js"></script>
<script src="app.module.js"></script>
<script src="core/hero/hero.service.js"></script>
<script src="app.config.js"></script>
</head>
<body>
<div ng-view></div>
</body>
</html>
and my core.module.js
'use strict';
angular.module('core',['core.hero']);
You need to change the order in which you load the references, load the core.module.js before loading app.module.js
<script src="https://code.angularjs.org/1.6.1/angular.min.js"></script>
<script src="https://code.angularjs.org/1.6.1/angular-route.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-resource/1.6.1/angular-resource.min.js"></script>
<script src="core/hero/hero.module.js"></script>
<script src="hero-grid/hero-grid.module.js"></script>
<script src="core/core.module.js"></script>
<script src="app.module.js"></script>
<script src="app.config.js"></script>
<script src="core/hero/hero.service.js"></script>
<script src="hero-grid/hero-grid.component.js"></script>
I am only a few days into AngularJS, and have been having trouble trying to print out this simple message. I have 2 files, one is "index.html" and the other is "app.js". They are mind-numbingly simple:
<!--index.html:-->
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<title>Testing Angular</title>
<script type="text/javascript" src="app.js"></script>
</head>
<body>
<div ng-controller="maryCtrl">
<p>{{mary}}</p>
</div>
</body>
</html>
<<!--end of index-->
//app.js:
var myApp = angular.module('myApp', []);
myApp.controller('maryCtrl', function ($scope) {
$scope.mary = 'had a little lamb.';
});
//end of app.js
The output on the page should be "had a little lamb." but I get "{{mary}}" instead. What really pisses me off is that I have a separate computer where it works just fine. I figure I must have a character wrong or am missing an extension, but I find that hard to believe since I just downloaded Visual Studio 2015 on this machine which has AngularJS and Angular-intellisense pre-loaded. Any help or criticism would be greatly appreciated.
you need a reference to the angular.js code.
make sure it is at the top of your script references.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.0-rc.2/angular.min.js"></script>
The link I provided is for a copy of the code that is hosted on a Google CDN. There are tons of benefits for using the CDN as opposed to having a local copy of angular.js on your computer (as long as you aren't trying to test your code offline).
You can find the CDN link on angularjs.org; Just click on the big blue download button and you will see options for obtaining the most recent version or legacy versions of angular.js
as #Pankaj Parkar commented, you should have angular.js file referenced before your app.js file:
<!--index.html:-->
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<title>Testing Angular</title>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript" src="app.js"></script>
</head>
<body>
<div ng-controller="maryCtrl">
<p>{{mary}}</p>
</div>
</body>
</html>
<<!--end of index-->
//app.js:
var myApp = angular.module('myApp', []);
myApp.controller('maryCtrl', function ($scope) {
$scope.mary = 'had a little lamb.';
});
//end of app.js
you can download it from https://github.com/angular/angular.js
So, I'm working on an Angular application and I have been having problems regarding compatibility between ngSanitize and ngDragDrop. ngDragDrop can be found at http://ganarajpr.github.io/angular-dragdrop/ and ngSanitize at https://docs.angularjs.org/api/ngSanitize/service/$sanitize.
The very moment I include ngSanitize on my app module, the angular code stops working entirely.
I have a test file called compatibility.html
<!DOCTYPE html>
<html ng-app="MyApp">
<head>
<meta charset='utf-8'>
<script src="compatibility.js"></script>
<script src="angular/angular.min.js"></script>
<script src="angular-resource/angular-resource.min.js"></script>
<script src="angular/angular-sanitize.min.js"></script>
<script src="angular/draganddrop.js"></script>
</head>
<body>
{{3+1}}
</body>
</html>
And another called compatibility.js
var app = angular.module("MyApp", ["ngDragDrop","ngSanitize"]);
app.controller("Controller", [ '$scope', '$sce', function($scope, $sce) {
}]);
I haven't the foggiest idea why it isn't working and I'm not sure what to do. Supposedly, evaluating {{3+1}} should return a 4 when the code is run, but it doesn't. I've worked with both ngSanitize and ngDragDrop separately, and the problem only shows when I try to use both simultaneously.
Try moving your compatibility.js file down to be under the angular.min.js.
Or just put it at the bottom like this:
<script src="angular/angular.min.js"></script>
<script src="angular-resource/angular-resource.min.js"></script>
<script src="angular/angular-sanitize.min.js"></script>
<script src="angular/draganddrop.js"></script>
<script src="compatibility.js"></script>
PS. I don't think there is any compatibility problems.
I've been sitting with this problem for a few hours and found a few answers, none of which have worked for me so far (AngularJs ReferenceError: angular is not defined). For some reason I can't seem to get my app to use Angular.JS. After adding the required js-files, my main file looks like this:
<!DOCTYPE html>
<html ng-app="AppName">
<head>
<title></title>
<link rel="stylesheet" href="/stylesheets/main.css">
</head>
<body>
<!-- Wrapper-->
<div id="wrapper">
<div id="page-content-wrapper">
<div class="page-content inset" ng-view>
</div>
</div>
</div>
<!-- /WRAPPER-->
<!-- ANGULAR CUSTOM -->
<script src="libs/angular/angular.js"></script>
<script src="libs/angular-route/angular-route.min.js"></script>
<script src="javascripts/AngularApp.js"></script>
<script src="javascripts/appRoutes.js"></script>
<script src="javascripts/controllers/MainCtrl.js"></script>
<script src="javascripts/controllers/SettingsCtrl.js"></script>
<script src="javascripts/services/SettingsService.js"></script>
</body>
</html>
When I run the app it never seems to finish loading (see the image: http://imgur.com/FIAH4tH) and then crashes. In Firefox, I get the following error: http://imgur.com/UT3g7wY
Does anyone know how I can solve this problem?
--EDIT--
I've updated the position of the scripts in the app.
My AngularApp.js file looks like this:
angular.module('AppName', ['ngRoute', 'appRoutes', 'MainCtrl', 'SettingsCtrl', 'SettingsService']);
If your module AppName is defined in AngularApp.js, that needs to come before MainCtrl js.
Are your .js files separate angular modules? If so, they should not be listed as modules in your angular.module dependencies.
angular.module('AppName', ['ngRoute']);
Definitely include any of the libs/ files before your own custom code.
So put <script src="libs/angular/angular.js"></script> and <script src="libs/angular-route/angular-route.min.js"></script> before your other javascripts files and you should find the problem fixed.
I was having the same problem. Declaring the angular script tag in html's <head> tag worked for me. Therefore:
<!doctype html>
<html lang="en" ng-app>
<head>
<meta charset="utf-8">
<title>AngularJS tryout</title>
<script src="../../node_modules/angular/angular.js"></script>
</head>
<body>
<h1>AngularJS tryout</h1>
<p>Nothing here so {{ 'far' + '!' }}</p>
</body>
</html>
