Booting up a module in AngularJS without using automatic bootstrapping

Here is the structure of my HTML...

<body id="main">
  {{pageName}}
</body>

This is how I implement it in JavaScript:

angular.module('myApp',[])
  .controller('myController', function($scope){
   console.log('initialized');
   $scope.pageName = 'My page';
});

angular.element(document).ready(function(){
   angular.bootstrap(document.getElementById('main'), ['myApp']);
});

After implementing, my HTML looks like this:

{{pageName}} instead of displaying 'My Page'

I noticed that if I change my code to:

<body id="main" ng-controller="myController">
</body>

it starts working properly. But why do I need to use ng-controller?

I hope that explains my issue clearly. Looking forward to some insights on this matter.

Answer №1

It seems that the issue stems from setting pageName in myController, but the div is unable to access it since the controller is not defined within it or its parent element.

To resolve this, you should assign pageName to $rootScope for proper functionality. This can be achieved by defining it in the run block of the module like so:

angular.module('myApp', []).run(function($rootScope) {
  $rootScope.pageName = 'My Page';
});

The run block executes after Angular has bootstrapped the application. More information on modules can be found here: http://docs.angularjs.org/guide/module
