This section explains briefly about how to create a Scroller in your application with JavaScript.

Create your first Scroller in AngularJS

Essential JS includes angular directives for all controls in the ej.widget.angular.min.js script file. All the Essential JS directives have been encapsulated into a single module called angular.min.js. To render our ej controls in angular, you need to refer the “angular.min.js” and “ej.widget.angular.min.js” in your application.

Essential JavaScript Scroller control can be rendered based on the target panel height and width, and includes more customization options.

Create a HTML file and paste the following template to the HTML file to create the ejScroller.

  • HTML
  • <!DOCTYPE html>
    <!doctype html>
    <html lang="en" ng-app="scrollerrApp">
        <title>Essential Studio for JavaScript : Angular JS Support for Tagcloud </title>
        <!-- Style sheet for default theme (flat azure) -->
        <link href="" rel="stylesheet" />
        <script src="" type="text/javascript"> </script>
        <script src=""></script>
        <script type="text/javascript" src=" "></script>
        <script src=""></script>
        <!--Add custom scripts here -->
    <body ng-controller="ScrollerCtrl">
                   <div class="control">
                      <div id="scrollcontent" ej-scroller e-height="300" e-width="600">
                            <div class="sampleContent">
                               <h3 style="font-size: 20px;">MVC</h3>
                                  <p>Model–view–controller (MVC) is a software architecture pattern which separates the
                                     representation of information from the user's interaction with it.
                                     The model consists of application data, business rules, logic, and functions. A view can be any
                                     output representation of data, such as a chart or a diagram. Multiple views of the same data 
                                     are possible, such as a bar chart for management and a tabular view for accountants. 
                                     The controller mediates input, converting it to commands for the model or view.The central 
                                     ideas behind MVC are code reusability and n addition to dividing the application into three 
                                     kinds of components, the MVC design defines the interactions between them.
                                        <b>A controller </b>can send commands to its associated view to change the view's presentation of the model (e.g., by scrolling through a document). 
                                        It can also send commands to the model to update the model's state (e.g., editing a document).
                                        <b>A model</b> notifies its associated views and controllers when there has been a change in its state. This notification allows the views to produce updated output, and the controllers to change the available set of commands. 
                                        A passive implementation of MVC omits these notifications, because the application does not require them or the software platform does not support them.
                                        <b>A view</b> requests from the model the information that it needs to generate an output representation to the user.

    The ng-app directive explains the root element (<html> or <body> tags) of the application. You will assign a name to the ng-app directive, then you must create a module with that name. In this module, you will have to define your directives, services, filters and configurations.

    A controller is defined using ng-controller directive. Each controller accepts an object $scope which we pass as a parameter. This object is used to bind the controller with view.

    Properties can be bind to ejScroller control using the prefix e- and particular property name.

    To render the ejScroller using angular directive, we need to inject the ej angular directive with modules.

    Initialize ejScroller in the target area in the script.

  • JS
  • <script>
            angular.module('scrollerrApp', ['ejangular'])
             .controller('ScrollerCtrl', function ($scope) {

    Configure the styles.

  • CSS
  • <style type="text/css">
            .control {
                border: 1px solid #bbbcbb;
                width: 600px;
                margin: 0 auto;
                height: 300px;
            .sampleContent {
                width: 700px;

    Scroller control is added to the application.
