    <div>
        <h3>AngularJS - Views</h3>
        <p>AngularJS supports Single Page Application via multiple views on a single page. To do this AngularJS has provided ng-view and ng-template directives and $routeProvider services.</p>
    </div>


    <div>
        <h3>ng-view</h3>
        <p>ng-view tag simply creates a place holder where a corresponding view (html or ng-template view) can be placed based on the configuration.</p>
        <h4>Usage</h4>
        <p>Define a div with ng-view within the main module.</p>
        <span ng-include="'subpage/1201-Views-ngview.html'"></span>
    </div>

    <div>
        <h3>ng-template</h3>
        <p>ng-template directive is used to create an html view using script tag. It contains "id" attribute which is used by $routeProvider to map a view with a controller. </p>
        <h4>Usage</h4>
        <p>Define a script block with type as ng-template within the main module.</p>
        <span ng-include="'subpage/1202-Views-ngtemplate.html'"></span>
    </div>

    <div>
        <h3>$routeProvider</h3>
        <p>$routeProvider is the key service which set the configuration of urls, map them with the corresponding html page or ng-template, and attach a controller with the same.</p>
        <h4>Usage</h4>
        <p>Define a script block with type as ng-template within the main module.</p>
        <span ng-include="'subpage/1203-Views-routeProvider.html'"></span>
        <h4>Usage</h4>
        <p>Define a script block with main module and set the routing configuration.</p>
        <span ng-include="'subpage/1203-Views-routeProvider2.html'"></span>
    </div>


    <p>Following are the important points to be considered in above example.</p>
    <ul>
        <li>$routeProvider is defined as a function under config of mainApp module using key as '$routeProvider'.</li>
        <li>$routeProvider.when defines a url "/addStudent" which then is mapped to "addStudent.htm". addStudent.htm should be present in the same path as main html page.If htm page is not defined then ng-template to be used with id="addStudent.htm". We've used ng-template.</li>
        <li>"otherwise" is used to set the default view.</li>
        <li>"controller" is used to set the corresponding controller for the view.</li>
    </ul>

    <h3>Example</h3>
    <h2>AngularJS Sample Application</h2>
    <div>
        <p><a href="#addStudent">Add Student</a></p>
        <p><a href="#viewStudents">View Students</a></p>
        <div ng-view></div>

        <!--<script type="text/ng-template" id="addStudent.htm">
            <h2> Add Student </h2>
            <p>{{message}}</p>
        </script>-->

        <script type="text/ng-template" id="viewStudents.htm">
            <h2> View Students </h2>
            <p>{{message}}</p>
        </script>
    </div>

    <script>
        var mainApp = angular.module("mainApp", ['ngRoute']);

        mainApp.config(['$routeProvider', function($routeProvider) {
            $routeProvider.

            when('/addStudent', {
                templateUrl: 'views/1201-Views-addStudent.html',
                controller: 'AddStudentController'
            }).

            when('/viewStudents', {
                templateUrl: 'viewStudents.htm',
                controller: 'ViewStudentsController'
            }).

            otherwise({
                //redirectTo: '/addStudent'
            });
        }]);

        mainApp.controller('AddStudentController', function($scope) {
            $scope.message = "This page will be used to display add student form";
        });

        mainApp.controller('ViewStudentsController', function($scope) {
            $scope.message = "This page will be used to display all the students";
        });

    </script>
