Can someone tell me why the hell this plunker is not working?
Sample AngularJS on Plunker
HTML :
<!DOCTYPE html>
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.6/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MyCtrl">
<p>{{userData}}</p>
</body>
</html>
JavaScript:
var app = angular.module('myApp', []);
app.controller('MyCtrl', function ($scope) {
$scope.userData = {
name: 'Xavier',
age: 25
}
});
you forgot to put ng-app.
<html ng-app="myApp">

Below is my code. Not sure why ng-repeat shows up completely blank.
Any help greatly appreciated.

Fix the typo

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)
{
$scope.message = "Hello!!!!";
};
app.controller("MainController1", MainController1);
</script>
</head>
<body ng-controller="MainController1">
<h1>{{message}}</h1>
</body>
</html>
I'm quite new with Node/Angular/.. and tried this simple script. But it doesn't work, whats wrong with it?
I always get Error: [ng:areq] http://errors.angularjs.org/1.3.0/ng/areq?p0=rCtlr&p1=not%20a%20function%2C%20got%20undefined
<!DOCTYPE html>
<html ng-app>
<head lang="en">
<meta charset="UTF-8">
<title>test</title>
<script src="lib/angular/1.3.0/angular.min.js"></script>
<script src="lib/socket.io/1.2.0/socket.io.js"></script>
</head>
<body ng-controller="rCtlr">
<h1>{{xTime}}</h1>
<script>
function rCtlr($scope){
var socket = io.connect();
socket.on('updateTime', function (data) {
$scope.xTime = data.updateTime;
console.log(data);
});
}
</script>
</body>
</html>
Without Angular it works fine, I guess there is an issue with the function scope?
Thanks for help!
To make it work properly you should:
1) Add name to your ng-app:
<html ng-app="myapp"> //myapp is an example name
2) Then you can define angular module and controller like this:
angular.module("myapp",[]) // define module with name from ng-app
.controller('rCtlr',['$scope', function($scope){ //define controller for your module
var socket = io.connect();
socket.on('updateTime', function (data) {
$scope.xTime = data.updateTime;
console.log(data);
});
}]);
alternatively (it does the same):
var app = angular.module("myapp",[]);
app.controller('rCtlr',['$scope', function($scope){
//controller body
}]);
PS. It doesn't matter, but name of you controller should be "rCtrl" rather than "rCtlr"
Here is a refference to angular docs: https://docs.angularjs.org/guide/controller
Update, thanks to MarkS: But .. see comment to Mark's answer

In my angular.js project I have the folowing:
{{ myString }}
Now when the value ofmyString is "#", The html output is as follows:
[Object][object]
How can I get round this?
I created the following example and the "#" is being displayed in the view. I can't duplicate the issue that you described. Can you provide more details?
Here's the code I used to display the "#".
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="angular.js"></script>
</head>
<body ng-controller="myCtrl">
Hello
{{myString}}
</body>
</html>
<script>
var myApp = angular.module("myApp", []);
myApp.controller("myCtrl", function($scope){
myScope = $scope;
$scope.myString = "#";
});
</script>
