Angular 'undefined is not a function' defining component - javascript

I had working ionic code to allow the user to input a list, which I tried to factor out into a component for re-use. But on running I get the error undefined is not a function in line 4 of the js. How can this be fixed?
/*jshint multistr: true */
var app = angular.module('ionicApp', ['ionic']);
app.component('inputlist',{
bindings: {label: '#'},
template: '\
<div class="list">\
<div class="item item-button-right">\
<ion-label floating>Enter {{$ctrl.label}} below then press +</ion-label>\
<input type="text" ng-model="nameinput.name"></input>\
<button class="button button-assertive" ng-click="addItem()">+</button>\
</div>\
<div class="item item-button-right" ng-repeat="item in items track by $index">\
<ion-label>{{item.name}}</ion-label>\
<button class="button button-positive" ng-click="items.splice($index,1)">-</button>\
</div>\
</div>',
controller: function() {
this.items = [];
this.nameinput = {name:''};
this.addItem = function(){
var name = this.nameinput.name.trim();
if (name!=="")
{
this.items.push({name:name});
this.nameinput={name:""};
}
};
}
});

You mentioned that you are using Ionic v1.0.0-beta1 in your project, which i believe that this version of ionic comes bundle with angular version below 1.3.
Component, on the other hand, is a new feature available in angular 1.5 and above. This explains why you got function is undefined in line 4 app.component() method.
I would suggest you to take either one of these 2 approach to resolve your issue:
1) Convert component to directive.
2) Upgrade the ionic to v1.3.2 (latest version) which supports angular 1.5

Problems writing out variables in AngularJS using Ionic

Using the ngCordova Barcode Scanner i am storing the barcode number and the barcode format in variables to output them in the app view. I wan't to be able to scan multiple barcodes which have to update the stored variable every time writing out the new barcode number and format. But when I scan multiple barcodes it just keeps on appending "Barcode: + barcodeNumber " instead of replacing. I cannot figure out what I am doing wrong. The app screenshot shows the problem.

if (barcodeData.cancelled == 1){
// Do nothing
}else{

$scope.barcodeNumber = "";
$scope.barcodeNumber = barcodeData.text;
$scope.barcodeFormat = barcodeData.format;
}
}, function(error){
console.log("Error: " + error);
});
}
});
So, it turned out that this error/bug was a result of the iOS automated phone number recognition. I solved the issue by adding a no format for phone numbers.

How to properly setup AngularJS files

Im familiar with the standard way of setting up a angularjs project, what I'm trying to do is set the app with separate files for different controllers and directives based on the page. See below for better explanation.
www /
app.js
index.html
login /
loginDirective.js
loginPage.html
This is my apps.js file
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
(function () {
'use strict';
angular.module('app', ['ionic']);
})();
var app=angular.module('app');
app.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
if(window.cordova && window.cordova.plugins.Keyboard) {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
// Don't remove this line unless you know what you are doing. It stops the viewport
// from snapping when text inputs are focused. Ionic handles this internally for
// a much nicer keyboard experience.
cordova.plugins.Keyboard.disableScroll(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});

this is my loginDirective.js
(function () {
'use strict';
var app=angular.module('app');
app.config(function($stateProvider) {
$stateProvider
.state('login', {
url: '/login',
template: '<loginDirective></loginDirective>'

What am I doing incorrectly that causes my loginPage.html to not show up?
I may be wrong, because I a novice with AngularJS, but if I were you, I firstly would try to change:
templateUrl : 'loginPage.html'
into:
templateUrl : 'login/loginPage.html'
I came to such conclusion, because you included loginPage.js file in index.html, so it tries look loginPage.html in www directory, or in directory where it was called.
I met such case like yours today, but with images.
You state definition has problems:
$stateProvider
.state('login', {
url: '/login',
//This should be kebab-case
template: '<login-directive></login-directive>'
//NOT camelCase
//template: '<loginDirective></loginDirective>'
})
})
But I am not sure why you are using a directive for that state when you could define the state with a controller:
.state('login', {
url: '/login',
templateUrl : 'loginPage.html',
controller : loginController,
controllerAs : 'lg'
});
Try moving <div login-directive></div> into the ion-view.
Also inspect the console to see if console.log('RETURN = %s', 'test'); is actually outputted. At least you'd then know if the state is active or not.
Like #georgeawg said, you're overcomplicating this by using a directive as template. Why you did that in this example is beyond me. Also, your $state config should be in your app.js file.

Impress.js and AngularJS Controller

I am running an AngularJS application/controller. My goal is to initialize and use the impress.js library on a page that is being dynamically loaded into my main home page. However, when I try to initialize the library, the page does not load. Attached is a snippet of the controller and html file.
NOTE: When I print the impress() object to the console, it is not null, and has the required functions. It is my suspicion that the impress() object is not hooking up to the page correctly.
Controller:
'use strict';
// Create the angular module
var cmodule = angular.module('coverage', ['ngRoute'])
// Create the coverage controller
cmodule.controller('coverageController', function($scope) {
console.log("Entering controller");
function require(script) {
$.ajax({
url: script,
dataType: "script",
async: true, // <-- This is the key
success: function () {
console.log(impress());
impress().init();
},
error: function () {
throw new Error("Could not load script " + script);
}
});
}
console.log("About to require");
angular.element(document).ready(function () {
require("/content/libraries/impress.js");
});
});

angular/ionic - model does not update $scope in controller

I am a newb with angularjs and I am trying something that I believe should be very simple ... but turns out I am not figuring it out.
I have a $scope variable that I want to double bind (using ng-model) to a textarea. I was able to make it work on js fiddle websites but now on my code. I have tried to strip everything down to just a few lines and it still doesn't work, the controller is never updated.
this is my code:
js/main.js
var app=angular
.module('noclu', ['ionic', 'app.controllers'])
.config(function ($stateProvider, $urlRouterProvider){
$stateProvider
.state('menu.main', {
url: "/main",
views: {
'menuContent': {
templateUrl: 'templates/main.html',
controller: 'MainCtrl'
}
}
});
$urlRouterProvider.otherwise("/menu/main");
});
js/controller.js
angular
.module('app.controllers', [])
.controller('MainCtrl', function ($scope){
$scope.src='---';
$scope.get_feeds=function(){
//seems like that here "this" is actually the textarea ??
//$scope.src is always whatever has been set in the controller
console.log('this:'+this.src); //this output whatever I enter in the textarea
console.log('scope:'+$scope.src); //this always output '---'
};
});

<div class="padding src-title">What are you in the mood for ?</div>
<div class="item" id="src-txt-wrapper">

Let's eat
</button>
</div>
</div>
</div>
</ion-content>
</ion-view>
UPDATE - I made it work, but why ?
I made it work by changing $scope.src='---'; to $scope.src={body:'---'}; and then changing the ng-modal to src.body. but.. WHY did not work the other way as it works for boolean?
Using directly $scope. is not a good practice in angularJS. There are various post of it, more concernign $scope inheritence.
For exemple : http://learnwebtutorials.com/why-ng-model-value-should-contain-a-dot
Therefore, your need to change your model like that :
$scope.myModel = {};
$scope.myModel.src = "---"
And your html to bind to myModel.src

Restify server with Angular, not working

I am learning to use Restify to build a Restful API and work with Angular.
Below is my structure:
Project
page_admin
core.js
index.html
node_modules
restify
mongojs
server.js
I had set up server and implemented several API calls.
Below news API return a list of JSON data in browser:
`http://localhost:8080/news`
`[{"_id":"53b2a2c3373551813dfe8b91","title":"first","subtitle":"foobar","textbody":"","postedOn":"2014-07-01T12:00:03.215Z"},{"_id":"53b2a122373551813dfe8b8e","title":"my second","subtitle":"my second title","textbody":"node is cool","postedOn":"2014-07-01T11:53:06.389Z"},{"_id":"53b2a0cd373551813dfe8b8d","title":"delay announcement","subtitle":"sub ","textbody":"I am the text body","postedOn":"2014-07-01T11:51:41.678Z"}]`
here is my code to handle client side route:
server.get('/', restify.serveStatic({
'directory': './page_admin',
'default': 'index.html'
}));
My index.html is simple:
<!-- index.html -->
<!doctype html>
<!-- ASSIGN OUR ANGULAR MODULE -->
<html ng-app="bluesky">
<head>
<!-- META -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1"><!-- Optimize mobile viewport -->
<title>My test app</title>
<!-- SCROLLS -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css"><!-- load bootstrap -->
<style>
html { overflow-y:scroll; }
body { padding-top:50px; }
#todo-list { margin-bottom:30px; }
</style>
<!-- SPELLS -->

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script><!-- load angular -->
<script src="core.js"></script>
</head>
<!-- SET THE CONTROLLER AND GET ALL TODOS -->
<body ng-controller="mainController">
<div class="container">
<!-- HEADER AND TODO COUNT -->
<div class="jumbotron text-center">
<h1>My example is working <span class="label label-info">{{ news.length }}</span></h1>
</div>
<!-- TODO LIST -->
<div id="todo-list" class="row">
<div class="col-sm-4 col-sm-offset-4">
<!-- LOOP OVER THE TODOS IN $scope.todos -->
<div class="checkbox" ng-repeat="new in news">
<label>
<input type="checkbox" ng-click="deleteTodo(new._id)"> {{ new.subtitle }}
</label>
</div>
</div>
</div>
</div>
</body>
</html>
core.js is like this:
var bluesky = angular.module('bluesky', []);
function mainController($scope, $http) {
$scope.formData = {};
$http.get('/news')
.success(function(data) {
$scope.news = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
}
when I try to navigate to: http://localhost:8080
I got my index page but it shows me:
'My example is working {{ news.length }}
and in console, I saw following error:
GET `http://localhost:8080/core.js` 404 (Not Found)
localhost/:24
Uncaught Error: No module: bluesky
angular.min.js:18
what I just missed so that the angular is not retrieving the data?
=============================================================
upate
if I directly include core.js put code inside , then it works.
but, how to solve this 404 not found issue? just don't want to include all js files in the index page.
As far as my knowledge about angular js, controller is not defined in your module. So instead of using function mainController($scope, $http) {
....
}
you should define controller inside the module bluesky as follows
bluesky.controller("mainController",function($scope,$http)
{
....
});
