Here is a snippet demonstrating how to inherit from a base controller using $controller and $scope:
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope, $controller) {
$controller('BaseCtrl', {
$scope: $scope
})
});
app.controller('BaseCtrl', function($scope) {
$scope.name = 'World';
});<!DOCTYPE html>
<html ng-app="app">
<head>
<meta charset="utf-8" />
<title>AngularJS</title>
<script>
document.write('<base href="' + document.location + '" />');
</script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<p>Hello {{name}}!</p>
</body>
</html>How can I do the same using "controller as" syntax? This snippet demonstrates what I am after, but it doesn't work:
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope, $controller) {
$controller('BaseCtrl', {
$scope: $scope
})
});
app.controller('BaseCtrl', function() {
this.name = 'World';
});<!DOCTYPE html>

<p>Hello {{main.name}}!</p>
</body>

You could use controller as syntax (or just use the ctrl instance returned by
$controllerprovider) and useangular.extend. But i don't think there is another way implicitly angular would do this, since "controller as" syntax ultimately places the controller instance on the respective scope as a property name specified as alias. But this really isn't inheritance, but utilizing object extension.Or you could use prototypical inheritance at the implementation level of the controller constructors itself. There are lots of syntactic sugars available, typescript's
extendsthere is another nice and simple example here as well.
