I create controller and html page.
'use strict';
angular.module('myApp.view3', ['ngRoute'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/view3', {
templateUrl: 'view3/view3.html',
controller: 'View3Ctrl'
});
}])
.controller('View3Ctrl', [function($scope) {
$scope.my_name = "Pasha";
}]);
and it is my html page.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My view</title>
</head>
<body>
<p> Hello Pavel</p>
<div>{{my_name}}</div>
</body>
</html>
I want show in browser my html.
Hello Pavel
Pasha
Angular seed app: v0.1
But I see in browser
Hello Pavel
{{my_name}}
Angular seed app: v0.1
I use example from link
EDIT: I add appjs.
It is my app js file my file it is my file:
'use strict';
// Declare app level module which depends on views, and components
angular.module('myApp', [
'ngRoute',
'myApp.view1',
'myApp.view2',
'myApp.view3',
'myApp.version'
]).
config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/view1'});
}]);
Add ng-app and ng-controller to your body
Add '$scope' in the controller
'use strict';
angular.module('myApp.view3', [])
.controller('View3Ctrl', ['$scope', function($scope) {
$scope.my_name = "Pasha";
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My view</title>
</head>
<body ng-app="myApp.view3" ng-controller="View3Ctrl">
<p> Hello Pavel</p>
<div>{{my_name}}</div>
</body>
</html>
HTML
<div ng-controller="View3Ctrl as ctrl">{{ ctrl.my_name}}</div>
You also need to set your documents ng-app attribute. See more in the docs.

New to angular. Had it running fine with no controller then added ng-controller directive to html markup and broke interpolation. Using Angular 1.6. What am I missing?
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>ngClassifieds</title>
</head>
<body ng-app="ngClassifieds" ng-controller="classifiedsCtrl">
<h1>{{ name }}</h1>
<!-- Scripts -->
<script src="node_modules/angular/angular.js"></script>
<script src="scripts/app.js"></script>
<script src="components/classifieds.ctr.js"></script>
</body>
</html>
app.js
angular.module("ngClassifieds", []);
classifieds.ctr.js
(function() {
"use strict"
angular
.module("ngClassifieds")
.controller("classifiedsCtrl", function($scope) {
$scope.name = "George Washington";
});
})();
It is like you are declaring the app twice, try this :
app.js
var myApp = angular.module("ngClassifieds", []);
classifieds.ctr.js
myApp.controller("classifiedsCtrl", function($scope) {
$scope.name = "George Washington";
});
I have a really dumb problem but I don't know how to fix it. I have this index.html file with AngularJS loaded. I'm using Plunker to test the code:
<!DOCTYPE html>
<html ng-app="">
<head>
<script data-require="angular.js#1.4.8" data-semver="1.4.8" src="https://code.angularjs.org/1.4.8/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="BodyController">
<h1>{{ message }}</h1>
</body>
</html>
And this script.js file with this information:
var BodyController = function($scope) {
$scope.message = "Hi Angular!"
}
In the inspector it says:
Error: [ng:areq] Argument 'BodyController' is not a function, got undefined
The script is loaded. I have defined the controller in the JS file and attach the ng-controller directive, so I don't know where this can fail.
This is very basic of AngularJS.
You first need to create a module:
var fooApp = angular.module("foo", [])
And then, register your controller there:
var BodyController = function($scope) {
$scope.message = "Hi Angular!"
}
fooApp.controller("BodyController", BodyController);
And, in your HTML tag, change your ng-app like this:
<html ng-app="foo"></html>
You need to add the controller to your Angular module.
angular.module('app', [])
.controller('BodyController', function($scope) {
$scope.message = "Hi Angular!"
})
More info on how to setup a controller
https://docs.angularjs.org/guide/controller
In HTML, add
<html ng-app="myapp">
and the script is
angular.module('myapp', []).controller('BodyController',BodyController)
There were several errors
ng-app was not set
angular module was not defined
the controller was not defined
angular.module('app', [])
.controller('BodyController', function($scope) {
$scope.message = "Hi Angular!"
});
<html ng-app="app">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body ng-controller="BodyController">
<h1>{{ message }}</h1>
</body>
</html>
Below code is not giving output as expected i:e Hello,World
output: {{ greetings.text }}, world
Can anyone help me why its not displaying 'hello, world' instead where I am wrong
<!doctype html>
<html ng-app>
<head>
<meta charset="utf-8">
<title>Angular JS App 1</title>
<script type="text/javascript" src="angular-v1.4.js"></script>
<script type="text/javascript" src="controllers.js"></script>
</head>
<body>
<div ng-controller='HelloController'> //controller
<p>{{ greetings.text }}, World</p>
</div>
</body>
</html>
script for controller
function HelloController($scope){
$scope.greetings = {text : 'hello'};
}
Global controller isn't allowed from 1.3.x
Try like this
var app = angular.module("app", []);
app.controller("HelloController", function($scope) {
$scope.greetings = {
text: 'hellow world'
}
});
HTML
add module name
<html ng-app="app">
add module name in ng-app..
like
<div ng-app='app'>
</div>
like this
<script>
angular.module('app', [])
.controller('testCtrl', ['$scope', function($scope){
$scope.test ="hello world";
}])
</script>
plunker code here
You need to provide the value for ng-app directive.
Like
<html ng-app="myapp">
and you should have the angular module myapp defined in script.
Having an issue using the ng-view to render a template from my controller.
The index.html file is initially served to the client and looks like.
<!doctype html>
<html lang="en" ng-app="hlmApp">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width,initial-scale=1">
<title></title>
<link rel="stylesheet" href="#Model.Root.Resource/bower_components\\/bootstrap/dist/css/bootstrap.css">
#RenderSection("BootScript")
<!-- app.js will load the angular module -->
<script src="#Model.Root.Resource/bower_components/angular/angular.js"></script>
<script src="#Model.Root.Resource/bower_components/angular-route/angular-route.js"></script>
<script src="#Model.Root.Resource/app/app.js"></script>
<script src="#Model.Root.Resource/app/controllers/controllers.js"></script>
</head>
<body>
<div class="container">
<div class="navbar">
<div class="navbar-inner">
<ul class="nav">
<li>A link here</li>
</ul>
</div>
</div>
<div ng-view></div>
#*<div ng-controller="tempController">{{Heading}}</div>*#
</div>
#RenderBody()
</body>
</html>
the server pushes down my app.js and controllers.js file along with the deps.
/// ap.js ///
var hlmApp = angular.module('hlmApp', ['ngRoute', 'MyTempControllers']);
hlmApp.config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/Holdings', {
templateUrl: 'templates/temp.html',
controller: 'controllers/tempController'
});
}]);
the controller is pretty simple and is as follows
var MyTempControllers = angular.module('MyTempControllers', []);
MyTempControllers.controller('tempController', ['$scope', function () {
console.log("stuff happening");
$scope.Heading = "Hello World";
}]);
then the html template is as follows
<div>
<h3>{{Heading}}</h3>
</div>
When I use the ng-view nothing ever renders. the controller is never triggered in the debugger. If I specifically call out the controller via the ng-controller then everything shows up. can someone point out my error here?
You need these 3 changes:
1) add $scope as a parameter in your controller function
MyTempControllers.controller('tempController', ['$scope', function ($scope) {
...
}]);
2.
Change
controller: 'controllers/tempController'
to
controller: 'tempController'
FYI, the naming convention for a controller is to begin with a capital letter for Controller.
3. In addition, you should add a
.otherwise({
template: templates/temp.html,
controller: 'tempController'
});
so that when no route matches, it goes to default-page-name.html. This is what's happening in your case, when you first load the page, no route matches. If you want to see temp.html, you have to 1) either click on a link that goes to #/Holdings, or 2) use '/Holdings' as the "otherwise" route, as indicated above.
Try this:
hlmApp.config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/Holdings', {
templateUrl: 'templates/temp.html',
controller: 'tempController' // just the name
});
}]);
and also $scope is missing in parameters:
MyTempControllers.controller('tempController', ['$scope', function ($scope) {
console.log("stuff happening");
$scope.Heading = "Hello World";
}]);
I included angular js in my asp.net mvc project but when i call object in controller
the angular js expressions do not evaluate
here is the app.js code please suggest
var app = angular.module('app', []);
app.controller('createController', createController);
and here is the createController code
var createController = function ($scope) {
$scope.mydata = 'I work!';
}
here is what i include in html
<html ng-app="app">
<script src="~/Scripts/angular.min.js"></script>
<script src="~/appAjs/app.js"></script>
<script src="~/appAjs/controllers/createController.js"></script>
<div ng-controller="createController">
{{scope.mydata}}
{{6+9}}
from your code, I can only suspect two things
your javascript does not have the proper scope
do not use the word scope in your "scope" code
first part: javascript scope:
Always use an IIFE, in your case your code should look like:
(function(){
var app = angular.module('app', []);
var createController = function ($scope) {
$scope.mydata = 'I work!';
};
app.controller('createController', createController);
}());
second part: don't use the word scope
in your HTML, you should not use the word scope as it's already inherit in your controller as that's the model you are passing to the "view"
hence, your code should look like:
<!DOCTYPE html>
<html ng-app="app">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
<meta charset="utf-8">
<title>JS Bin</title>
</head>
<body>
<div ng-controller="createController">
{{mydata}}
{{6+9}}
</div>
</body>
</html>
the result is:
I work! 15
live code in JSBIN so you can check it out.
your HTML page, all together should look like this:
if you have only one file
<!DOCTYPE html>
<html ng-app="app">
<head>
<meta charset="utf-8">
<title>My AngularJs App</title>
</head>
<body>
<!-- HTML -->
<div ng-controller="createController">
{{mydata}}
{{6+9}}
</div>
<!-- AngularJS required -->
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
<!-- AngularJS code -->
<script>
(function(){
var app = angular.module('app', []);
var createController = function ($scope) {
$scope.mydata = 'I work!';
};
app.controller('createController', createController);
}());
</script>
</body>
</html>
if you're using 2 files
file index.html
<!DOCTYPE html>
<html ng-app="app">
<head>
<meta charset="utf-8">
<title>My AngularJs App</title>
</head>
<body>
<!-- HTML -->
<div ng-controller="createController">
{{mydata}}
{{6+9}}
</div>
<!-- AngularJS required -->
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
<!-- AngularJS extra files -->
<script src="createController.js"></script>
</body>
</html>
file createController.js (in the same folder as index.html)
(function(){
var app = angular.module('app', []);
var createController = function ($scope) {
$scope.mydata = 'I work!';
};
app.controller('createController', createController);
}());
I think the problem may well be the order in which you are including your scripts:
Try the following:
<script src="~/Scripts/angular.min.js"></script>
<script src="~/appAjs/controllers/createController.js"></script>
<script src="~/appAjs/app.js"></script>
Reasoning is that app.js tries to define a controller using a function that has not been defined when the function is run.
Points that {{scope.data}} should be {{data}} are correct, but do not explain {{6+9}} not working.
You need to create the controller in the context of the app module.
Your app.js should just have
angular.module('app', []);
and your createController code should look similar to this
angular.module('app')
.controller('createController', function ($scope) {
$scope.mydata = 'I work!';
});
You need to change the expression from
{{scope.mydata}}
to
{{mydata}}
Expression have access to scope and no keyword is required to access a scope object.
