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>

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){
$scope.cpu = [
{ house: 'Intel', model: 'I7' },
{ house: 'AMD', model: 'Ryzen' },
{ house: 'Qualcomm', modello: 'Snapdragon' }
];
});
</script>
</head>
<body ng-app="angularApp">
<div ng-controller="Controller">
<input type="search" ng-model="q" placeholder="CPU" />
<ul>
<li ng-repeat="proc in cpu | filter:q">
{{proc.house}} - {{proc.model}}
</li>
</ul>
</div>
</body>
</html>
I just started learning AngularJS and facing a problem. When I run the follwing code {{ cust.name }} - {{ cust.city }} gets printed instead of the actual data that I pass.
My code:
<html data-ng-app="">
<head>
<title>Using angularJS directive and data binding </title>
</head>
<body>
<div data-ng-controller="SimpleController">
Name:
<br/>
<input type="text" data-ng-model="name" />
<br/>
<ul>
<li data-ng-repeat="cust in customers | filter:name"> {{ cust.name }} - {{ cust.city }}
</li>
</ul>
</div>
<script src="Scripts/angular.min.js"></script>
<script>
function SimpleController($scope) {
$scope.customers = [{
name: 'Abhijeet Singh',
city: 'New Delhi'
}, {
name: 'Dhiraj Mehta , city: New Delhi '
}];
}
</script>
</body>
</html>
A few things are missing from your code.
First it is good practice to name your app and a controller:
<body data-ng-app='myApp' data-ng-controller='myCtrl'>
Second whenever you refer to anything in Angular is has to be in scope of the controller. Currently your $scope is in scope of the "SimpleController" function and not of Angular's controller (you need an angular controller to have $scope available both within the controller and within your html e.g. the double curly brackets):
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
//$scope is available anywhere within this scope
}
Here is an example of your code working: https://jsfiddle.net/AKMorris/03hshn5m/
You will need to declare the app name and see the other settings.
Rest of the things are same.
var myApp = angular.module("MyApp", []);
var simpleController = angular.module("SimpleController", SimpleController);
simpleController.$inject = ['$scope'];
function SimpleController($scope){
$scope.customers = [{
name: 'Abhijeet Singh',
city: 'New Delhi'
}, {
name: 'Dhiraj Mehta , city: New Delhi '
}];
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html data-ng-app="MyApp">
<head>
<title>Using angularJS directive and data binding </title>
</head>
<body>
<div data-ng-controller="SimpleController">
Name:
<br/>
<input type="text" data-ng-model="name" />
<br/>
<ul>
<li data-ng-repeat="cust in customers | filter:name"> {{cust.name }}-{{cust.city}}
</li>
</ul>
</div>
</body>
</html>
I wrote a file new.html and I am trying to test navigation. But when i load the page View1.html should be loaded but it shows a blank page.
Here is my new.html:
<!DOCTYPE html>
<html data-ng-app="demoApp">
<head>
<title> Angular Test</title>
</head>
<body>
<div>
<div data-ng-view></div>
</div>
<script src = "Scripts/angular.min.js"></script>
<script src="Scripts/angular-route.min.js"></script>
</body>
<script>
var demoApp = angular.module('demoApp', ['ngRoute']);
demoApp.config(function ($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>
Name: <br/>
<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>
City:
<br/>
<input type="text" data-ng-model="city" />
<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
I am new to angular js
Controller is not working correctly in my code

</html>
but its not giving desire output .
please tell me if i am doing something wrong .
You are missing to add value in your ng-app directive that tell angular to run demoApp module on the page.
ng-app="demoApp"
You should add the name of your app.
ng-app="demoApp"
var demoApp = angular.module('demoApp', []);
demoApp.controller('SimpleController', function($scope) {
$scope.customers = [{
name: 'John Smith',
city: 'kashipur'
}, {
name: 'John fds',
city: 'san francisko'
}, {
name: 'shubham',
city: 'giarhineg'
}, {
name: 'batra',
city: 'world'
}];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="demoApp">
name
<br />
<div data-ng-controller="SimpleController">
<input type="text" data-ng-model="name" />{{name}}
<ul>
<li data-ng-repeat="cust in customers | filter:name | orderBy:city">{{cust.name | uppercase}}-{{cust.city | lowercase}}</li>
</ul>
</div>
</div>
I am learning AngularJS. I am trying to list out the variable in controller. I have this in the script.
var demoController = angular.module('sampleController',[]);
demoController.controller('sampleController', function ($scope){
$scope.customers=[
{name:'John Smith', country:'Denmark', worth:'5000000'},
{name:'John Lewis',country:'England',worth:'10000000'},
{name:'Rick Evans',country:'America',worth:'6000000'}
];
});
And I have this in the HTML.
<html ng-app="demoController">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<body>
<h1>Applying filters</h1>
<div ng-controller="sampleController">
<ul>
<li ng-repeat="cust in customers">{{ cust.name }} - {{ cust.country }} - {{ cust.worth | currency:"$":2 }}</li>
</ul>
</div>
</body>
</html>
It is not listing out the variable. What is wrong with this script. Thanks!!
You need to define your module in the right way
var app = angular.module('app',[]);
Then, use it in your HTML file
<html ng-app="app">
See it working on jsbin
Note that, the angular module's name is the one defined within the quotes
angular.module('app',[]);
So, if you wrote var xModule = angular.module('app2',[]); your module name is app2 not xModule
Here is the code I am using :
<meta name="robots" content="noindex">
<html data-ng-app="app">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<body>
<h1>Applying filters</h1>
<div data-ng-controller="sampleController">
<ul><li data-ng-repeat="cust in customers">{{ cust.name }} - {{ cust.country }} - {{ cust.worth | currency:"$":2 }}</li></ul>
</div>
<script id="jsbin-javascript">var app = angular.module('app',[]);
app.controller('sampleController', function ($scope){
$scope.customers=[
{name:'John Smith', country:'Denmark', worth:'5000000'},
{name:'John Lewis',country:'England',worth:'10000000'},
{name:'Rick Evans',country:'America',worth:'6000000'}
];
});
</script>
</body></html>
And the output is :
Applying filters
{{ cust.name }} - {{ cust.country }} - {{ cust.worth | currency:"$":2 }}
Let me know what is missing here.
