Angularjs external templating: the template cannot be loaded? - javascript

I thought loading an external template with Angularjs is as simple as this below,
<div ng-include='template/index.php'></div>
But it does not print anything out on the browser. What have I missed?
The html,
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Angualr</title>
<meta charset="utf-8">

<script src="js/maincontroller.js" type="text/javascript"></script>
</head>
<body>
<div ng-include='template/index.php'></div>
</body>
</html>
the template,
<div id='content' ng-app='MyTutorialApp' ng-controller='MainController'>
<input type='text' ng-model='searchText' />
<ul>
<li ng-repeat='person in people | filter:searchText' ng-show='person.live == true'>#{{person.id}} {{person.name}}</li>
</ul>
<input type='text' ng-model='newPerson' />
<button ng-click='addNew()'>Add</button>
</div>
js/app.js,
var app = angular.module('MyTutorialApp',[]);
js/maincontroller.js,
app.controller("MainController", function($scope){
$scope.people = [
{
id: 0,
name: 'Leon',
music: [
'Rock',
'Metal',
'Dubstep',
'Electro'
],
live: true
},
{
id: 1,
name: 'Chris',
music: [
'Indie',
'Drumstep',
'Dubstep',
'Electro'
],
live: true
}
];
$scope.newPerson = null;
$scope.addNew = function() {
if ($scope.newPerson != null && $scope.newPerson != "") {
$scope.people.push({
id: $scope.people.length,
name: $scope.newPerson,
live: true,
music: [
'Pop',
'RnB',
'Hip Hop'
]
});
}
}
});

Live demo here (click).
ng-include looks for a $scope property, so you need to pass it a string, like this: ng-include="'/template/index.php'".
<div ng-include="'/template/index.php'"></div>
What you were passing to it essentially makes it look for this in your controller: $scope['/template/index.php'] = 'some string';
You're also bootstrapping angular in the template itself - so how could it be included? ng-app needs to be in the main page so that ng-include can work!
<some-element ng-app="myApp">
<!-- in here, angular things work (assuming you have created an app called "myApp" -->
<div ng-include="'/template/index.php'"></div>
</some-element>
Just replace some-element with something like html, body or whatever element you want the app to work from.

You bootstrapped your ng-app in the template, but you have to bootstrap it in your main page.
So just move the ng-app directive from the template to the main-page, e.G.
<html ng-app="MyTutorialApp">

<div ng-include src='template/index.php'></div>
try this
and add ng-app into top of the page
<html ng-app='MyTutorialApp'>
you must have bootstrap you angular application into your index.html

Display elements in scope in angularjs page

Hy everybody, first question here.
I'm learning angularjs and right now i'm stuck on "Controller and Scope" chapter.
I'm trying to search trough an array of objects and show items that match my query; unfortunately my screen stays blank.
Here's my code:
<!DOCTYPE html>
<html ng-app="">
<head>
<title>Search and print with Scope</title>
</head>
<body>
<div ng-controller="Controller">
<input type="search" ng-model="q" placeholder="CPU" />
<ul>
<li ng-repeat="proc in cpu | filter:q">
{{proc.house}} - {{proc.model}}
</li>
</ul>
</div>
<script src="angular.min.js"></script>
<script>
function Controller($scope)
$scope.cpu = [
{ house: 'Intel', model: 'I7' },
{ house: 'AMD', model: 'Ryzen' },
{ house: 'Qualcomm', modello: 'Snapdragon' }
];
</script>
</body>
</html>
What's wrong?
EDIT for EDIT:Just for those who might look at this question, my error was to call ng-app twice, once in the html tag and once in body tag.
EDIT: I'm here again; I modified the code using the given answers, but I still got a search box and a blank screen. I doubt is code related since I also tried to simply copy and paste it in a new file but i got the same result. What could be?
Code is down here:
<!DOCTYPE html>
<html ng-app="">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script>
var app = angular.module('demoApp', [])
app.controller('SimpleController', function($scope) {
$scope.cpu = [{
house: 'Intel',
model: 'I7'
},
{
house: 'AMD',
model: 'Ryzen'
},
{
house: 'Qualcomm',
model: 'Snapdragon'
}
];
});
</script>
<title>Search and print with Scope</title>
</head>
<body ng-app="demoApp">
<div ng-controller="SimpleController">
<input type="search" ng-model="q" placeholder="CPU" />
<ul>
<li>hi</li>
<li ng-repeat="proc in cpu">
{{proc.house}} - {{proc.model}}
</li>
<li>hi again</li>
</ul>
</div>
</body>
</html>
You need to have a angular module and ng-app mentioned as below
DEMO
var app = angular.module('myApp',[])
app.controller('Controller',function($scope){
$scope.cpu = [
{ house: 'Intel', model: 'I7' },
{ house: 'AMD', model: 'Ryzen' },
{ house: 'Qualcomm', modello: 'Snapdragon' }
];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html ng-app="myApp">
<head>
<title>Search and print with Scope</title>
</head>
<body>
<div ng-controller="Controller">
<input type="search" ng-model="q" placeholder="CPU" />
<ul>
<li ng-repeat="proc in cpu | filter:q">
{{proc.house}} - {{proc.model}}
</li>
</ul>
</div>
</body>
</html>
First of all you are trying to get the scope data before declaring it, you need to load the script before using ng-repeat, so move the script before the div definition.
Also you are not correctly defining the Controller, it should be defined within an app module, then bind the ng-app and the Controller in your HTML.
<!DOCTYPE html>
<html ng-app="">
<head>
<title>Search and print with Scope</title>
<script src="angular.min.js"></script>
<script>
var app = angular.module('angularApp',[])
app.controller('Controller',function($scope){
$scope.cpu = [
{ house: 'Intel', model: 'I7' },
{ house: 'AMD', model: 'Ryzen' },
{ house: 'Qualcomm', modello: 'Snapdragon' }
];
});
</script>
</head>
<body ng-app="angularApp">
<div ng-controller="Controller">
<input type="search" ng-model="q" placeholder="CPU" />
<ul>
<li ng-repeat="proc in cpu | filter:q">
{{proc.house}} - {{proc.model}}
</li>
</ul>
</div>
</body>
</html>

Multiple controllers working within ngRoute example

I have a small ngRoute example I am trying that to use multiple applications and controllers with. The first app/controller is for the main page, while the second set of app/controller is for the html that ngRoute loads up after pressing a button. However, it doesn't seem to be working. Code below:
Main Module
var app = angular.module("MainModule", ["ngRoute"]);
Main Controller
app.controller("MainController", function ($scope) {
});
app.config(function ($routeProvider) {
$routeProvider
.when('/customers', {
templateUrl: "customers.html",
controller: "CustomerController"
})
});
Customer Module
var CustomerModule = angular.module("CustomerModule", []);
Customer Controller
CustomerModule.controller("CustomerController", function ($scope) {
$scope.Test = "Hey";
$scope.CustomerArray = [
{ "firstName" : "John", "lastName" : "Williams", "Occupation" : "Fireman" },
{ "firstName" : "Louis", "lastName" : "Abrams", "Occupation" : "Policeman" }
]
});

<div ng-app="CustomerModule" ng-controller="CustomerController">
{{Test}}
<ul>
<li ng-repeat="x in CustomerArray">{{x.firstName x.lastName x.Occupation}}</li>
</ul>
</div>
</body>
</html>
Long bits of code there, but hopefully simple code. The output when I press the "Load Customer" button is literally {{Test}} with no array data to follow.
I am just now learning angular, so any help with this issue I would appreciate. I am just doing this for fun, to try to learn. So I suppose the issue is not pressing. :) Thanks!
I wrote out a working example using the code from the question as a base. There are quite a few adjustments that were made, so I will list each piece with a bit of explanation.
It is not necessary for each "page" to have it's own module. However, it is not a bad practice. To support the design you have here of one module for each view, I made the following changes:
Include the CustomerModule as a dependency in the MainModule (MainModule.js):
var app = angular.module("MainModule", ["ngRoute", "CustomerModule"]);
Load ALL scripts in the index.html:
<script src="scripts/MainModule.js"></script>
<script src="scripts/MainController.js"></script>
<script src="scripts/CustomerModule.js"></script>
<script src="scripts/CustomerController.js"></script>
With these changes, the $routeProvider is able to locate the CustomerController and instantiate it during a route change. The customers.html now does not have to create a controller, and can be stripped down to a complete partial. Also, the expression used in customers.html needed to be changed, and broken down into individual expressions for each property.
The final customers.html:
{{Test}}
<ul>
<li ng-repeat="x in CustomerArray">{{x.firstName}} {{x.lastName}} {{x.Occupation}}</li>
</ul>

I'm not sure, but the problem is in your MainModule. It should be like this or so:
var app = angular.module("MainModule", ["ngRoute"]);
When you calling angular.module with only one parameter - it's only trying get module, not create.
And customers.html should only contains parts of you html, not full:
Full customers.html
{{Test}}
<ul>
<li ng-repeat="x in CustomerArray">{{ x.firstName }} {{ x.lastName }} {{ x.Occupation }}</li>
</ul>
And add move customer js files to index.html:
<script src="scripts/MainModule.js"></script>
<script src="scripts/MainController.js"></script>
<script src="scripts/CustomerModule.js"></script>
<script src="scripts/CustomerController.js"></script>
<link rel="stylesheet" type="text/css" href="MyCSS.css">
Hope, it helps.

Angular- View Not loading

I wrote a file new.html and I am trying to test navigation. But when i load the page View1.html should be loaded but it shows a blank page.
Here is my new.html:
<!DOCTYPE html>

<title> Angular Test</title>
</head>

<div>
<div data-ng-view></div>

var demoApp = angular.module('demoApp', ['ngRoute']);
demoApp.config(function ($routeProvider) {
$routeProvider
.when('/',
{
controller: 'SimpleCtr',
templateUrl: 'View1.html'
})
.when('/2',
{
controller: 'SimpleCtr',
templateUrl: 'View2.html'
})
.otherwise({ redirectTo: '/' });
});
demoApp.controller('SimpleCtr', function($scope) {
$scope.customers = [
{ name:'Rajat', city:'Kanpur' },
{ name:'Adarsh', city:'Lucknow' },
{ name:'Manoj', city:'Banaras' }
];
$scope.addCustomer = function() {
$scope.customers.push({ name: $scope.newCustomer.name, city: $scope.newCustomer.city });
}
});
</script>
</html>
And here is my View1.html:
<div class="container">
<h2> View 1 </h2>

<input type="text" data-ng-model="filter.name"/>
<br/>
<ul>
<li data-ng-repeat = "cust in customers | filter:filter.name | orderBy:'city'"> {{cust.name}} </li>
</ul>
Customer Name: <br/>
<input type="text" data-ng-model="newCustomer.name"/>
<br />
Customer City: <br />
<input type="text" data-ng-model="newCustomer.city"/>
<br />
<button data-ng-click = "addCustomer()"> Add Customer </button>
<a href = "#/2" > View 2 </a>
</div>
Here is View2.html:
<div class="container">
<h2> View 2 </h2>

<br/>
<ul>
<li data-ng-repeat = "cust in customers | filter:filter.city | orderBy:'city'"> {{cust.name}} </li>
</ul>
</div>
Please help me where i am going wrong?
You are missing a closing bracket in your code on line 8
<!DOCTYPE html>
<html data-ng-app="demoApp">
<head>
<title> Angular Test</title>
</head>
<body>
<div>
<div data-ng-view> </div> <!-- right here -->
</div>
I created a plunker here: http://plnkr.co/edit/uj4S1ybv7vJSsQctG1nD
http://plnkr.co/edit/uj4S1ybv7vJSsQctG1nD
Your views aren't loaded because you try to access them using the file:// protocol. If you put your website on a HTTP server (XAMPP for example) you'll get the desired result.
It works fine with Plnkr. http://plnkr.co/edit/NmfnOMTRHXzsLkcHfgZX?p=preview
My best guess is you are not running the file in HTTP server. The simplest HTTP server is, run this command in your working directory:
python -m SimpleHTTPServer
Then, request your program in browser
localhost:8000/new.html

AngualrJS controller not working

I just began to learn AngularJS by following this youtube video. First part is okay except when it comes to the controller part.
My code is as below (it's the same as in the video)
<html data-ng-app="">
<head>
<script src="angular.min.js"></script>
<script>
function SimpleController($scope) {
$scope.customers = [{
name: 'Kamal',
city: 'York'
}, {
name: 'Sunil',
city: 'DC'
}, {
name: 'Malith',
city: 'Gotham'
}];
}
</script>
</head>
<body>
<div data-ng-controller="SimpleController">Name :
<input type="text" data-ng-model="name" />
</br>
<ul>
<li data-ng-repeat="cust in customers | filter :name | orderBy:'city'">{{cust.name | uppercase}} - {{cust.city}}</li>
</ul>
</div>
</body>
</html>
when I add data-ng-controller="SimpleController" it will not working and give the following error in the console.
Then when I try to post the question in the SO , I tried it in JSfiddle. I added Angular.js and selected onLoad and not working. But when I selected no wrap - in <head> it works fine.
But I can't do that in my local machine so the problem remains as it is.
Can anybody point me to the correct path ?
You need to initialize app:
var app = angular.module("myApp", []);
<div ng-app="myApp" ng-controller="SimpleController">
<!-- ^^^^^ -->
Demo: http://jsfiddle.net/xy23ybzp/2/
Docs: https://docs.angularjs.org/guide/bootstrap
Check Manual Initialization Section in Docs
After getting help from the answers listed here for this question. I got it working. Below is the working code.
<html >
<head>
<script src = "angular.min.js" ></script>
<script>
var app = angular.module("myApp", []);
app.controller("SimpleController",function($scope){
$scope.customers = [
{name :'Kamal',city : 'York'},
{name : 'Sunil',city:'DC'},
{name : 'Malith',city:'Gotham'}
];
});
</script>
</head>
<body >
<div ng-app="myApp" data-ng-controller="SimpleController">
Name :
<input type="text" data-ng-model="name" />
</br>
<ul>
<li data-ng-repeat="cust in customers | filter :name | orderBy:'city'">{{cust.name | uppercase}} - {{cust.city}}</li>
</ul>
</div>
</body>

Angularjs templating: model and function stop working in external templates?

After this question, I am facing another challenge, the model and function inside the $scope seem have stopped working. Below is the test code, the Add button seem does not collect any data I input from <input type='text' ng-model='newPerson' /> anymore,
html,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>AngularJS</title>
<meta charset="utf-8">
<script src="js/jquery-1.10.1.min.js"></script>
<script src="js/angular.min.js"></script>
<script src="js/app.js" type="text/javascript"></script>
</head>
<body>
<div ng-app='MyTutorialApp' ng-controller='MainController'>
<div ng-include='thisIsAScopeProperty'></div>
</div>
</body>
</html>
the external template,
<div id='content'>
<input type='text' ng-model='searchText' />
<ul>
<li ng-repeat='person in people | filter:searchText' ng-show='person.live == true'>#{{person.id}} {{person.name}}</li>
</ul>
<input type='text' ng-model='newPerson' />
<button ng-click='addNew()'>Add</button>
</div>
angularjs,
var app = angular.module('MyTutorialApp',[]);
app.controller("MainController", function($scope){
$scope.thisIsAScopeProperty = 'template/index.html';
$scope.people = [
{
id: 0,
name: 'Leon',
music: [
'Rock',
'Metal',
'Dubstep',
'Electro'
],
live: true
}
];
$scope.newPerson = null;
$scope.addNew = function() {
alert(1); // works here when you click the Add button
console.log($scope.newPerson); // but returns nothing when you type any text in the input
if ($scope.newPerson != null && $scope.newPerson != "") {
alert(2); // does not work here
$scope.people.push({
id: $scope.people.length,
name: $scope.newPerson,
live: true,
music: [
'Pop',
'RnB',
'Hip Hop'
]
});
}
}
});
Any ideas why and how can I fix it?
Use
<input type='text' ng-model='$parent.newPerson' />
ng-include creates a new scope, and because newPerson is a simple property, it's a different one on the child and parent scopes (i.e. changing one doesn't change the other). So when the included template sets newPerson it's still null on the mainController's scope.
