I have just started learning AngularJS but I am stuck at this point. I made three files in one project:
1.Index.html
2.Angular.min.js( downloaded from official site)
3.Script.js
But when I am opening html in browser I am not getting the value of test property. It just shows the {{test}} (not the value). Will be very thankful if you help me out.
<!DOCTYPE html>
<html lang="en" ng-app = "myapp">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body ng-controller = "MyCtrl">
{{test}}
<script src = "angular.min.js"</script>
<script src = "script.js"></script>
</body>
</html>***
Script.js file is
var app = angular.module('myapp',[]);
app.controller('MyCtrl', ['$scope', function($scope){
$scope.test = "Welcome to my world";
}]);
Check the network tab be sure angular itself is actually loading copying and pasting your code into a running sample.
var app = angular.module('myapp',[]);
app.controller('MyCtrl', ['$scope', function($scope){
$scope.test = "Welcome to my world";
}]);
<!DOCTYPE html>
<html lang="en" ng-app = "myapp">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body ng-controller = "MyCtrl">
{{test}}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.js"></script>
<!--
you were missing a > here
<script src = "angular.min.js"</script>
<script src = "script.js"></script>
-->
</body>
</html>

I have come across a lot of similar issues here on SF and did everything as expected. Yet, I can't seem to get this simple Angular app working. Console throws up this exception
angular.min.js:6 Uncaught Error: [$injector:modulerr]
AngularJS site docs gave some suggestions which I followed. Yet, I still get that same exception. Here is my code.
<!DOCTYPE html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="utf-8">
<title>Dead Simple Proj</title>
<link rel="stylesheet" href="content/css/styles.css">
<script scr="app\app.js"></script>
<script src="app\lib\angular.min.js"></script>
</head>
<body>
<div ng-controller="GreetingController">
{{ greeting }}
</div>
</body>
</html>
I have this in the App.js
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});
I double checked file paths and other possibly obvious mistakes, but no joy.
I am definitely missing out something here? Thanks.
Your paths referencing the libraries and the app.js are wrong and in the wrong order . You should load the angular reference first and then the relative js referencing the module.
Change
From
<script scr="app\app.js"></script>
<script src="app\lib\angular.min.js"></script>
To
<script src="app/lib/angular.min.js"></script>
<script scr="app/app.js"></script>
DEMO
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});
<!DOCTYPE html>
<html lang="en" ng-app="myApp">

<meta charset="utf-8">

<link rel="stylesheet" href="content/css/styles.css">
<script type=" text/javascript " src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.6/angular.js "></script>
</head>
<body>
<div ng-controller="GreetingController">
{{ greeting }}
</div>
</body>
</html>
I dont think you added your angular files properly. I made a plunker out of your code and it worked. you can cross check with my code.
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});
<html ng-app="myApp">
<head>
<script data-require="angular.js#1.6.2" data-semver="1.6.2" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.2/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="GreetingController">
<h1>Hello {{greeting}}!</h1>
</body>
</html>
I am new in angularjs, so i try this script in Index.html like this:
<!DOCTYPE html>
<html lang="en" ng-app="DEMO">
<head>
<title></title>
</head>
<body>
<h1 ng-controller="HelloWorldCtrl">{{HelloMessage}}</h1>
<script src="angular.min.js"></script>
<script type="text/javascript">
function HelloWorldCtrl($scope) {
$scope.HelloMessage = "Hello Pejman";
}
</script>
</body>
</html>
but when i run this, it show {{HelloMessage}} instead of Hello Pejman , what is the problem?
EDIT : this is the tutorial:
You did not bootstrap angular module, that is why your code doesnt work. You must call ng-app in any HTML tag to notify Angular start in there. So all of the sub tags under the tag Angular declared will be able to use directives, scope, controller etc.
Please check here to understand how to create controller and use it : https://docs.angularjs.org/guide/controller
Try this:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Hello World</title>
<script src="angular.min.js"></script>
</head>
<body>
<h1 ng-app="demo" ng-controller="HelloWorldCtrl">{{HelloMessage}}</h1>
<script type="text/javascript">
var app = angular.module('demo', []);
app.controller('HelloWorldCtrl', function($scope) {
$scope.HelloMessage = "Hello Pejman";
});
</script>
</body>
</html>
My task is to show Hello, Angular! in the browser, using AngularJS.
This is my HTML:
<!DOCTYPE html>
<html ng-app>
<head>
<title>Introduction to AngularJS Application</title>
<script src="Scripts/MyScripts/Example01Scripts.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
This is my JavaScript:
/// <reference path="../angular.js" />
var MainController = function ($scope) {
$scope.message = "Hello, Angular!";
};
And here's what I'm getting:
This is my expected result:
<!DOCTYPE html>
<html ng-app>
<head>
<title>Introduction to AngularJS Application</title>
<script src="Scripts/MyScripts/Example01Scripts.js"></script>
</head>
<body ng-controller="MainController">
<h1>Hello, Angular!</h1>
</body>
</html>
The interpolation isn't functioning correctly. Why is this, and how can I fix it?
I have taken your code and updated it. You were missing the app name in ng-app. Click Run code snippet to see it working.
angular.module('myApp', []).controller('MainController', function($scope){
$scope.message = "Hello, Angular!";
});
<html ng-app="myApp">
<head>
<title>Introduction to AngularJS Application</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
On the HTML you're missing the Angular source code and your app name on ng-app directive.
On the JS you're missing the module declaration.
HTML should be something like
<!DOCTYPE html>
<html ng-app="MyApp">
<head>
<title>Introduction to AngularJS Application</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script src="Scripts/MyScripts/Example01Scripts.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
and your Example01Scripts.js should be something like:
angular.module('MyApp', []).controller('MainController', function($scope){
$scope.message = "Hello, Angular!";
});
Looks like the module was missing. Have created a wee test script that will do what you wanted.
Code example here
I am following a tutorial but stuck on one issue. I don't know what I am missing here.
//script.js
var MainController = function($scope)
{
$scope.message = "Hello!!!!";
};
<!-- index.html -->
<!DOCTYPE html>
<html ng-app>
<head>
<script data-require="angular.js#1.3.4" data-semver="1.3.4" src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
Problem is -
The message is not binding.
Create your module first, then add the controller to the module, specify both the app and controller in your HTML portion.
<!DOCTYPE html>
<html ng-app="app">
<head>
<script data-require="angular.js#1.3.4" data-semver="1.3.4" src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<script>
var app = angular.module('app',[]);
var MainController1 = function($scope)
{
$scope.message = "Hello!!!!";
};
app.controller("MainController1", MainController1);
</script>
</head>
<body ng-controller="MainController1">
<h1>{{message}}</h1>
</body>
</html>
What is wrong?
<!doctype html>
<html lang="en" ng-app='SOO'>
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div ng-controller='someController'>
<p>{{someData}}</p>
</div>
<script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.7/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.7/angular-route.min.js"></script>
<script>
$(function(){
var app = angular.module('SOO', ['ngRoute']);
app.controller('someController', function($scope){
$scope.someData = 'Ok, all good!';
})
})
</script>
</body>
</html>
And error message in the console:
Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.3.0-beta.7/$injector/modulerr?p0=app&p1=Error…s.org%2F1.3.0-beta.7%2F%24injector%2Fnomod%3Fp0%3Dapp%0A%20%20%20%20at%20E...<omitted>...2) angular.js:36
But examples from the official site are working normal. I can't see the serious difference.
Change:
var app = app.module('SOO', ['ngRoute']);
To:
var app = angular.module('SOO', ['ngRoute']);
And remove the jQuery document ready handler that is wrapping your code:
<script>
var app = angular.module('SOO', ['ngRoute']);
app.controller('someController', function($scope){
$scope.someData = 'Ok, all good!';
});
</script>
From the documentation:
Angular initializes automatically upon DOMContentLoaded event or when
the angular.js script is evaluated if at that time document.readyState
is set to 'complete'. At this point Angular looks for the ng-app
directive which designates your application root.
Just remove Jquery statement $(function(){}), then everything works fine.
