It is time to create a real AngularJS Single Page Application (SPA).
You have learned more than enough to create your first AngularJS application:
The application file "myNoteApp.js":
The controller file "myNoteCtrl.js":
The <html> element is the container of the AngularJS application: ng-app="myNoteApp":
A a <div> in the HTML page is the scope of a controller: ng-controller="myNoteCtrl":
An ng-model directive binds a <textarea> to the controller variable message:
The two ng-click events invoke the controller functions clear() and save():
An ng-bind directive binds the controller function left() to a <span> displaying the characters left:
Your application libraries are added to the page (after the library):
Above you have the skeleton (scaffolding) of a real life AngularJS, single page application (SPA).
The <html> element is the "container" for the AngularJS application (ng-app=).
A <div> elements defines the scope of an AngularJS controller (ng-controller=).
You can have many controllers in one application.
An application file (my...App.js) defines the application module code.
One or more controller files (my...Ctrl.js) defines the controller code.
The ng-app directive is placed at the root element the application.
For single page applications (SPA), the root of the application is often the <html> element.
One or more ng-controller directives define the application controllers. Each controller has its own scope: the HTML element where they were defined.
AngularJS starts automatically on the HTML DOMContentLoaded event. If an ng-app directive is found, AngularJS will load any module named in the directive, and compile the DOM with ng-app as the root of the application.
The root of the application can be the whole page, or a smaller portion of the page. The smaller the portion, the faster the application will compile and execute.
