Sample text

But there is a slight twist here, which is the array notation. Notice that we have defined our controller definition function inside an array. That is, the first argument to the controller function on the module is the name of the controller (MainCtrl), and the second argument is an array. The array holds all the dependencies for the controller as string variables, and the last argument in the array is the actual controller function. In this case, because we have no dependencies, the function is the only argument in the array.

This is the first and most important directive that AngularJS has, which denotes the section of HTML that AngularJS controls. Putting it on the tag tells AngularJS to control the entire HTML application. We could also put it on the or any other element on the page. Any element that is a child of that will be handled with AngularJS and be annotated with directives, and anything outside would not be processed. Finally, we have our first taste of AngularJS one-way data-binding. We have put the expressions “1+2” within double curly braces.

Waiting for AngularJS to Load AngularJS has a directive called ng-cloak, which is a mechanism to hide sections of the page while AngularJS bootstraps and finishes loading. important; } After this, any section or element that needs to be hidden in your HTML needs to have class="ng-cloak" added to it. This applies the preceding CSS and hides the element by default. After AngularJS finishes loading, it goes through your HTML and removes ng-cloak from all these elements, thus ensuring that your UI is shown after AngularJS has finished bootstrapping.
