AngularJS supports single-page applications (Single Page Application) through multiple views on a single page. To achieve this, AngularJS provides ng-view and ng-template directive, and $routeProvider service.
ng-The view directive only creates a placeholder, where you can place the corresponding view (HTML or ng-template view).
In the main module, use ng-view defines div.
<div ng-app "mainApp"> ... <div ng-view></div></div>
ng-The template directive is used to create HTML views using script tags. It includesidproperties, which are used by $routeProvider to map views to controllers.
In the main module, define the script block as ng-template.
<div ng-app "mainApp"> ... <script type "text/ng-template" id "addStudent.htm"> <h2> Add Student </h2> {{message}} </script> </div>
$routeProvider is a key service that can set URL configurations and map them to corresponding HTML pages or ng-template mapping, and attach a controller to it.
In the main module, define the script block as ng-template.
<div ng-app "mainApp"> ... <script type "text/ng-template" id "addStudent.htm"> <h2> Add Student </h2> {{message}} </script> </div>
Use the main module to define a script block and set the routing configuration.
var mainApp = angular.module("mainApp", ['ngRoute']); mainApp.config(['$routeProvider', function($routeProvider) { $routeProvider .when('/addStudent', { templateUrl: 'addStudent.htm', controller: 'AddStudentController' }) .when('/viewStudents', { templateUrl: 'viewStudents.htm', controller: 'ViewStudentsController' }) .otherwise({ redirectTo: ''/addStudent }); });
The following points are very important in the above example-
$routeProvider is defined as a function under the mainApp module configuration, using the key '$routeProvider'.
$routeProvider.when defines the URL “/addStudent”, which maps to “ addStudent.htm”. addStudent.htm should be located in the same path as the main HTML page. If the HTML page is not defined, then the ng-template is used together with id ="addStudent.htm". We use ng-template.
"otherwise" is used to set the default view.
"controller" is used to set the corresponding controller for the view.
The following example demonstrates the use of all the above directives.
