View above Codepen. The Chrome DevTools console returns Error: [$injector:modulerr]. The same error occurs when script area is commented.
However, when script area is commented and the (identical) JS section is uncommented, Angular works fine with no errors. Why does this happen??
Note: I have a large application and isolated the bug to this phenomenon. I'm using a Prepros server and I'm getting this same annoying $injector error.
<div ng-app="testApp">
<div ng-controller="testController">
<h1>{{title}}</h1>
</div>
</div>
<script>
var app = angular.module('testApp',[]);
app.controller('testController', function($scope){
$scope.title = "Hello, World!";
});
</script>
<div ng-app="testApp">
<div ng-controller="testController">
<h1>{{title}}</h1>
</div>
</div>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>
<script>
var app = angular.module('testApp', []);
app.controller('testController', function($scope) {
$scope.title = "Hello, World!";
});
</script>
Your angularjs library reference is not applied to your code.
In codepen,Attach your script in HTML rather than mentioning in settings window,
CODEPEN DEMO
Problem is codepen in HTML window you can have only HTML code,
Check here it works,
<body>
<div ng-app="testApp">
<div ng-controller="testController">
<h1>{{title}}</h1>
</div>
</div>
<script>
var app = angular.module('testApp', []);
app.controller('testController', function($scope) {
$scope.title = "Hello, World!";
});
</script>
</body>
DEMO
Codepen adds the code after the HTML, so the script you have initializing Angular won't have access to angular. If you change to this it will work.
<div ng-app="testApp">
<div ng-controller="testController">
<h1>{{title}}</h1>
</div>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/angular.min.js"></script>
<script>
var app =
angular.module('testApp', []).controller('testController', function($scope){
$scope.title = "Hello, World!";
});
</script>

I'm a beginner, I have a simple Angular JS that's not working, I don't understand why, here is my code (the two files index.html & script.js are in the same folder):
index.html :
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script src="script.js"></script>
<body ng-app>
<p>Name: <input type="text" ng-model="name"></p>
<p ng-bind="name"></p>
<div ng-controller="MainController">
{{message}}
</div>
</body>
</html>
script.js :
var MainController = function($scope) {
$scope.message = "Hello";
};
The ng-model is working, the name that I write in the textbox gets displayed, but I get {{message}} instead of the actual message Hello that I have in the scope of the controller.
Thank you in advance.
Name your app
<body ng-app="myApp">
Create an app.js
var app = angular.module("myApp", []);
Rename script.js to MainController.js , (Don't have to, but for a clean development)
app.controller('MainController', ['$scope', function($scope) {
$scope.message = "Hello";
}]);
I have an application where a part of the page is implemented in angular js. I have a requirement where I have to reload the angular js template coming from the server, based on some user action. I have simulated the exact situation with a dummy code,
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.7/angular.min.js"></script>
<script type="text/javascript">
var angApp = angular.module("app", []);
angApp.controller("mainCtrl", function($scope){
$scope.p1 = "Hello1";
$scope.p2 = "Hello2";
})
angular.element(document).ready(function() {
angular.bootstrap(document, ['app']);
});
function add(){
var tpl = "<div>{{p1}}</div><div>{{p2}}</div>";
$("#container").html("");
$("#container").html(tpl);
angular.element(document).injector().invoke(function($compile){
var obj=$('#angApp');
var scope = angular.element($("#angApp")).scope();
$compile(obj.contents())(scope);
scope.$digest();
});
var angControllerScope = angular.element($("#angApp")).scope();
angControllerScope.$apply(function() {
angControllerScope.p1 = "New Hello";
});
}
</script>
<body>
<button type="button" onclick="add()">Add</button>
<div id="angApp" ng-controller="mainCtrl">
<div id="container">
<div>{{p1}}</div>
<div>{{p2}}</div>
</div>
</div>
</body>
On click of Add button how to get the value as "Hello" again.
Thanks.
Sorry if i have misunderstood what you mean but this is what i think you are trying to achieve...
var app = angular.module('app', []);
app.controller('mainController', function($scope) {
$scope.p1 = 'Hello';
$scope.add = function() {
$scope.p1 = 'New Hello'
}
});
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body ng-app="app">
<div class="container" ng-controller="mainController">
<button type="button" ng-click="add()">Add</button>
{{p1}}
</div>
</body>
</html>
Found the solution. I had to recompile the template so that the binding with controller again works fine. Below link was useful.
https://gist.github.com/umidjons/1fb8ae674df4c71f85cf
I have updated the initial code with the working version.
I had already declared my app and controller in separate file and below is how i am loading my controller html DOM but it is not showing that message. Can someone please guide how to achieve this.
HTML:
<div id="bnProblemList">
<div ng-controller="problemListCtrl" data-ng-init="init()">
<div ng-view="">this is my message = {{message}}</div>
</div>
</div>
JS:
html = $j('#bnProblemList').html();
$compile(html)(scope);
Please let me know how to inject or load ng-controller html dynamically.
Your controller declaration is wrong. You should do it like this:
var myApp = angular.module('myApp',[]);
myApp.controller('problemListCtrl', ['$scope',
function($scope) {
$scope.message = "This is my message :-)";
}
]);
A proper way is to declare your Controller into an anonymous function, and add it to a module. Then, you have to set your ngApp.
Controller.js
Here, we will declare our controller, and create an app module. Then, we will declare ctrl as our controller into our app module.
(function(){
function Controller($scope) {
$scope.name = 'toto';
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
HTML
<body ng-app='app' ng-controller="ctrl">
<p>My name is {{name}}</p>
</body>
And don't forget to include your script tag :
<script src="controller.js"></script>
You can try Like below Example:-
Html Page:
<!DOCTYPE html>
<html ng-app="MyApp">
<head>
<title> Controller</title>
<script src="../Js/angular.min.js"></script>
<script src="../Js/Controller.js"></script>
</head>
<body>
<div ng-controller="MyFirstController">
{{ Msg }}
</div>
</body>
</html>
ControllerJs Page:
var MyApp=angular.module("MyApp",[]);
MyApp.controller("MyFirstController",function($scope){
$scope.Msg="Hello First Conroller";
})
i was able to load/ inject controller dynamically by the help of below code
<div id="bn" ng-controller="myCtrl as vm">
<div ui-view=''></div>
</div>
<script>
angular.element(document).injector().invoke(function($compile, $state) {
$state.go('myCtrl');
var scope = angular.element($j("#bn")).scope();
$compile($j("#bn"))(scope);
});
</script>
Im trying to show an Angularjs's variable value in HTML with the following code:
<div ng-controller="MyTextbox">
<p>Fecha de ultima actualizacion: {{nodeID1}} </p>
Here is the code for my angularjs controller:
angular.module("umbraco").controller("MyTextbox", function ($scope,$routeParams) {
$scope.nodeID1 = "Hello World";
});
But nothing display this way.
Any help?
You need to write ng-app="umbraco"before ng-controller directive, or write it on body/html tag would be preferable.
Markup
<div ng-app="umbraco" ng-controller="MyTextbox">
<p>Fecha de ultima actualizacion: {{nodeID1}} </p>
</div>
and your app should be
angular.module("umbraco",[]).controller("MyTextbox", function ($scope,$routeParams) {
$scope.nodeID1 = "Hello World";
});
Note
If $routeParams has not added mistakenly then your app would be
angular.module("umbraco",['ngRoute']) then you need to additionally add angular-route.js
Try:
<!DOCTYPE>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script>
angular.module("umbraco",[]).controller("MyTextbox", ['$scope', function ($scope, $routeParams) {
$scope.nodeID1 = "Hello World";
}]);
</script>
</head>
<body >
<h1>My Textbook</h1>
<div ng-app="umbraco" ng-controller="MyTextbox">
<p>Fecha de ultima actualizacion: {{nodeID1}}</p>
</div>
</body>
</html>
I'm learning Angular.js right now by following along with the videos at Egghead.io. I'm at the $routeProvider video, and my app isn't routing at all.
It's ultra basic, here's the script (app.js):
var app = angular.module('myApp', []);
// routes
app.config(function ($routeProvider) {
$routeProvider.when('/pizza', { template: 'Yum!!' });
});
app.controller('FirstCtrl', function ($scope) {
$scope.data = { message: "Hello" };
});
And the html:
<div ng-app="myApp">
<div ng-controller="FirstCtrl">
{{data.message + " world"}}
</div>
</div>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.1.3/angular.min.js"></script>
<script src="app.js"></script>
From my understanding, http://host/#/pizza should simply show "Yum!!" since I'm passing a string in the template. It doesn't appear to do anything though, I still get "Hello world" as evaluated by the FirstCtrl.
Why isn't the $routeProvider doing anything in my app?
You need to put an ng-view element in where you want the routeProvider to stick the page's template.
<div ng-app="myApp">
<div ng-controller="FirstCtrl">
{{data.message + " world"}}
<ng-view></ng-view>
</div>
</div>
Note that indicating it like below keeps you cross-browser compliant.
<div ng-view> </div>
or, for that matter:
<ANY ng-view> </ANY>
