AngularJS Views

AngularJS Scopes

Using ng-view and ng-template directives and $routeProvider services you can provide single page application via multiple views on a single page.

ng-view: A place holder where a corresponding view can be placed.
ng-template: Used to create an html view using script tag with the help of “id” attribute.
$routeProvider: Set the configuration of urls and map them with the corresponding html page via attaching controller.

If htm page is not defined then ng-template will be used with id=”addStudent.htm”.

Following example will show the above criteria:

Save the file as angularview.html and run into browser.
