Following is the code in angular js to show the array input value .but i want to show the array input value out of the angular js loop
<!DOCTYPE html>
<html>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<html ng-app="">
<body ng-init="names = ['Sam', 'Harry', 'Sally']">
<p>names: {{names}}</p>
<h3>Binding to each element directly:</h3>
<div ng-repeat="feature in names">
Value: {{feature}}
<input ng-model="feature">
</div>
</body>
</html>
</html>
I would create a controller for the view and in that:
#scope.names = ['Sam', 'Harry', 'Sally']
Then access each entry in the view with {{names[index]}}

I'm a newbie to this thing called 'AngularJS' so I got stuck at one point.
Consider the below code sample :
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="" ng-init="firstName='John'">
<p>Input something in the input box:</p>
<p>Name: <input type="text" ng-bind="firstName"></p>
<p>You wrote: {{ firstName }}</p>
</div>
</body>
</html>
In above example why can't I bind the value of application variable "firstName" to the HTML input text control usng "ng-bind"?
and suppose I write the code as below :
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="" ng-init="firstName='John'">
<p>Input something in the input box:</p>
<p>Name: <input type="text" ng-model="firstName"></p>
<p>You wrote: {{ firstName }}</p>
</div>
</body>
</html>
In above example I can bind the value of application variable "firstName" to the HTML input conrol using "ng-model".
Can someone please clarify me the difference between the above two codes in easy to understand language?
Also, look at below code snippet :
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="" ng-init="firstName='John'">
<p>The name is <span ng-bind="firstName"></span></p>
</div>
</body>
</html>
In the above(third) example how could I be able to bind the value of application variable "firstName" to the <p> tag?
Someone please explain me.
Thanks.
ng-bind makes a one way binding between your controller and the view. In this case, the view will only reflect changes made in the controller, but not viceversa. This is the same as using the double brackets notation {{variable}}
In the other hand, ng-model makes a double binding, that is, changes made in the view (normally in an input form), will be accesible automatically in the controller, and changes made in the controller will be updated in the view

In regard to the snippet, you could just do:
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller='myController'>
<p>{{firstName}}</p>
</div>
</body>
</html>
Which implements a one way bind. So, if you have your application defined in this way:
var app=angular.module('myApp',[]);
app.controller('myController', ['$scope',function($scope){
$scope.firstName = 'John Doe';
}]);
It would make a one-way binding between your variable firstName in the controller and the view.
It is better to use controllers for this type of work.
<html ng-app="notesapp">
<head>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.min.js"></script>
</head>
<body>
<script type="text/javascript"></script>
NAME:<input ng-model="name" type="text"> <br/>
Hello: <span ng-bind="name"></span>
</body>
</html>
Edit
For making small code like this work, we can actually define an empty ng-app.
Eg: <html ng-app = "">
If you however want to define ng-app with some value, we need to load that ng-app in javascript. It can be done in a separate js file or in the same html file with <script></script> tag. Please see below:
<script>
var app = angular.module('notesapp', []);
</script>
Please close the script tag in your head. Also angular needs ng-app for its functioning. Please use ng-app on the tag which encloses your angular content.
<html ng-app="notesapp">
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.min.js"></script>
</head>
<script>
var app = angular.module('notesapp', []);
</script>
<body>
<script type="text/javascript"></script>
NAME:<input ng-model="name" type="text"> <br/>
Hello: <span ng-bind="name"></span>
</body>
</html>
Also, as you know, Sublime is just an editor. It has nothing to do with angular. Cheers.
The following html page works when ng-app="" but not when ng-app="MyApp". How can I make this page work with ng-app="MyApp"?
The code in this page will print out the text being input as user types into the textbox.
<!DOCTYPE html>
<html>
<head>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
</head>
<body>
<div ng-app="MyApp">
<p>Input something in the input box:</p>
<p>Name: <input type="text" ng-model="name" value="John"></p>
<p ng-bind="name"></p>
</div>
</body>
</html>
I tried including following JavaScript in this page, but still it did not work.
<script>
angular.element(document).ready(function() {
angular.bootstrap(document, ['MyApp']);
});
</script>
UPDATE 1
The following script did the trick, which I picked up after reading various responses to my post. I added this just before the closing 'body' tag.
<script>
angular.module('MyApp', []);
</script>
You need to declare your module in Angular. You must declare it in javascript whithin your file:
angular.module('MyApp', []);
Here you have a good starting tutorial:

i'm new to angular, so started with very basic example, but this is also not working. so please help me out. below code should write the content of textbox to the page.
<html xmlns="http://www.w3.org/1999/xhtml">
<head ng-app>
<title></title>
</head>
<body>
<div class="container">
Name: <input type="text" ng-model="name" />{{name}}
</div>
<script src="/script/angular.js" type="text/javascript"></script>
</body>
</html>
ng-app should be inside html or body, inside whichever tags you intend to use angular.
In your code ng-app scope is ending with in head tags only. You haven't used ng-app at root level. You can use it at html or body or main div tag level. And there is no ng-controller in your markup. Of course you can also configure controller through js file also.
You use below code.
HTML
<html ng-app="plunker">
<head>
<script data-require="angular.js#1.3.x" src="https://code.angularjs.org/1.3.14/angular.js" data-semver="1.3.14"> </script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<div class="container">
Name: <input type="text" ng-model="name" />{{name}}
</div>
</body>
</html>
JS
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
});
ng-app should be in html tag, not head.
put ng-app in tag, not in head tag
Remove ng-app directives which is added to head tag and assign it to html
What is the Simplest 'Hello World' in AngularJS for a beginner. So far I have this:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div data-ng-app="">
{{'Hello World' }}
</div>
<script src="angular.js"></script>
</body>
</html>
Simplest Hello World that shows 2-way databinding
<!doctype html>
<html lang="en" ng-app>
<head>
<title> Hello World </title>
</head>
<body ng-controller="MainCtrl">
<h1>{{helloWorld}}</h1>
<input type="text" ng-model="helloWorld"></input>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>
<script type="text/javascript">
function MainCtrl($scope){
$scope.helloWorld = "Hello World";
}
</script>
</body>
</html>
edit:
A bit of explanation on what is what and why this is (in my view) a minimal Hello World app showcasing the power of AngularJS
The AngularJS library needs to be included
The custom attribute ng-app is added to kick of the angular application. This directive signals AngularJS to auto-bootstrap an application
The ng-controller directive is added and it's associated javascript function shows exposing an object by assigning it to the injected $scope
The double brackets expression {{helloWorld}} shows the convention used by AngularJS to output model values.
The ng-model directive is used to bind the helloWorld object and shows the power of AngularJS two-way datababinding
