Getting started in EJ2 JavaScript Sidebar control

25 Nov 202324 minutes to read

The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Component Initialization

Create an app folder myapp in local machine to initialize Essential JS 2 JavaScript components.

Using either of the following way to refer the required script and styles.

  • Using local script and style references in a HTML page.
  • Using CDN link for script and style reference.

Using local script and style references in a HTML page

Step 1: Create an app folder myapp for Essential JS 2 JavaScript components.

Step 2: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

Syntax:

Script: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\dist\global\{PACKAGE_NAME}.min.js

Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\styles\material.css

Example:

Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-navigations\dist\global\ej2-navigations.min.js

Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-navigations\styles\material.css

The below located script and style file contains all Syncfusion JavaScript (ES5) UI control resources in a single file.

Scripts: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\dist\ej2.min.js

Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\material.css

Step 3: Create a folder myapp/resources and copy/paste the above mentioned packages from the above installed location to myapp/resources location.

Step 4: Create a HTML page (index.html) in myapp location and add the Essentials JS 2 script and style references.

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>Essential JS 2</title>
            <!-- Essential JS 2 material theme -->
            <link href="resources/material.css" rel="stylesheet" type="text/css"/>

            <!-- Essential JS 2 Sidebar's global and dependent script -->
            <script src="resources/ej2-base.min.js" type="text/javascript"></script>
            <script src="resources/ej2-navigations.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

Step 5: Now, add the div element and initiate the Essential JS 2 Sidebar component in the index.html by using following code

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <title>Essential JS 2</title>
    <!-- Essential JS 2 material theme -->
    <link href="resources/material.css" rel="stylesheet" type="text/css"/>

    <!-- Essential JS 2 Sidebar's global and dependent script -->
    <script src="resources/ej2-base.min.js" type="text/javascript"></script>
    <script src="resources/ej2-navigations.min.js" type="text/javascript"></script>
</head>

<body>
    <!-- Add the HTML <div> element  -->
    <div id='container'>
        <aside id="default">
            <div class="title"> Sidebar </div>
        </aside>
        <!-- end of sidebar element -->
        <!-- main content declaration -->
        <div>
            <div class="title">Main content</div>
            <div class="sub-title"> Content goes here</div>
        </div>
    </div>
    <script>
        // initialize Sidebar component
        var defaultSidebar = new ej.navigations.Sidebar();

        // Render initialized sidebar.
        defaultSidebar.appendTo('#default')
    </script>
</body>

</html>

Step 6: Now, run the index.html in web browser, it will render the Essential JS 2 Sidebar component.

Step 1: The Essential JS 2 components scripts and styles are already hosted in the below CDN link formats.

Syntax:

Script: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Style: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: http://cdn.syncfusion.com/ej2/ej2-navigations/dist/global/ej2-navigations.min.js

Styles: http://cdn.syncfusion.com/ej2/ej2-navigations/styles/material.css

Step 2: Have to add CDN global script and style for Sidebar and its dependent packages in myapp/index.html like below.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <title>Essential JS 2 Sidebar Component</title>
    <!-- Sidebar and its dependent theme -->
    <link href="http://cdn.syncfusion.com/ej2/ej2-base/styles/material.css" rel="stylesheet" type="text/css" />
    <link href="http://cdn.syncfusion.com/ej2/ej2-navigations/styles/material.css" rel="stylesheet" type="text/css" />
    <!-- Essential JS 2 Sidebar's global script -->
    <script src="http://cdn.syncfusion.com/ej2/ej2-navigations/dist/global/ej2-navigations.min.js" type="text/javascript"></script>
</head>

<body>
    <!-- Add the HTML <div> element  -->
    <div id='container'>
        <aside id="default">
            <div class="title"> Sidebar </div>
        </aside>
        <!-- end of sidebar element -->
        <!-- main content declaration -->
        <div>
            <div class="title">Main content</div>
            <div class="sub-title"> Content goes here</div>
        </div>
    </div>
    <script>
        // initialize Sidebar component
        var defaultSidebar  = new ej.navigations.Sidebar();

        // Render initialized sidebar.
        defaultSidebar.appendTo('#default')
    </script>
</body>

</html>

When referencing CDN links in application, always ensure the network connection will be in enabled state.

Enable backdrop

Enabling the showBackdrop in the Sidebar component will prevent the main content from user interactions, when it is in expanded state.
Here, the DOM elements will not get changed. It only closes the main content by covering with a black backdrop overlay and focuses the Sidebar in the screen. Sidebar can be rendered with specific width by setting width property.

NOTE

To achieve a proper backdrop, we suggest that you create a wrapper parent container for the div block in which you intend to enable the backdrop. Set the class name of this parent container as the target for the Sidebar. Alternatively, you can place an empty div container after the target container.

ej.base.enableRipple(true);
   //sidebar initialization
   var defaultSidebar = new ej.navigations.Sidebar({
        showBackdrop: true,
        type: "Push",
        width: '280px'
    });
    defaultSidebar.appendTo('#default-sidebar');
    //end of sidebar initialization

    // Toggle(Open/Close) the sidebar
    document.getElementById('toggle').onclick = function() {
        defaultSidebar.toggle();
    };

    // Close the sidebar
    document.getElementById('close').onclick = function() {
        defaultSidebar.hide();
    };
    //end of sidebar initialization

    // Toggle(Open/Close) the sidebar

if(ele) {
  ele.style.visibility = "visible";
}   
      </script>
<script src="index.js" type="text/javascript"></script>
</body></html>

Position

Positioning the Sidebar to the right or left of the main content can be achieved by using the position property. If the position is not set, the Sidebar will expand from the left to the body element. enablePersistence will persist the component’s state between page reloads. change event will be triggered when the state(expand/collapse) of the component is changed.

ej.base.enableRipple(true);
   //sidebar initialization
   var defaultSidebar = new ej.navigations.Sidebar({
        showBackdrop: true,
        enablePersistence:true,
        type: "Push",
        width: '280px'
    });
    defaultSidebar.appendTo('#default-sidebar');
    //end of Sidebar initialization

    //toggle button initialization

    var togglebtn = new ej.buttons.Button({iconCss: 'e-icons burg-icon', isToggle: true, content:'Open'}, '#toggle');

    //Click Event for toggle button to triger show/hide methods of Sidebar
    document.getElementById('toggle').onclick = function(){
        if (document.getElementById('toggle').classList.contains('e-active')) {
            togglebtn.content = 'Close';
            defaultSidebar.show();
        } else {
            togglebtn.content = 'Open';
            defaultSidebar.hide();
        }
    };

    // Close the sidebar
    document.getElementById('close').onclick = function() {
        defaultSidebar.hide();
        document.getElementById('toggle').classList.remove('e-active');
        togglebtn.content = 'Open'
    };

    var positionLeft = new ej.buttons.RadioButton({ label: 'Left', name: 'state', checked: true,change:Change });
    positionLeft.appendTo('#left');

    //unchecked state
    var positionRight = new ej.buttons.RadioButton({ label: 'Right', name: 'state',change:Change });
    positionRight.appendTo('#right');

    //change the position of the Sidebars
    function Change(args){
    defaultSidebar.position = (args.event.target.id == "left") ? "Left" : "Right";
    }

Animate

Animation transitions can be set while expanding or collapsing the Sidebar using the animate property. By default , animate property is set to true. enableRTL will display the sidebar in the right-to-left direction.

ej.base.enableRipple(true);
   
   var defaultSidebar = new ej.navigations.Sidebar({
        type: "Push",
        width: '280px',
		animate: false,
        enableRtl: true
    });
    defaultSidebar.appendTo('#default-sidebar');
    //end of Sidebar initialization

   // Toggle(Open/Close) the sidebar
    document.getElementById('toggle').onclick = function() {
        defaultSidebar.toggle();
    };

    // Close the sidebar
    document.getElementById('close').onclick = function() {
        defaultSidebar.hide();
    };
    //end of sidebar initialization

    // Toggle(Open/Close) the sidebar

Close on document click

Sidebar can be closed on document click by setting closeOnDocumentClick to true. If this property is not set, the Sidebar will not close on document click since its default value is false. Sidebar can be kept opened during rendering using isOpen property.

ej.base.enableRipple(true);
   
   var defaultSidebar = new ej.navigations.Sidebar({
        type: "Push",
        width: '280px',

    });
    defaultSidebar.appendTo('#default-sidebar');
    //end of Sidebar initialization

  // Toggle(Open/Close) the sidebar
    document.getElementById('toggle').onclick = function() {

Enable gestures

Expand or collapse the Sidebar while swiping in touch devices using enableGestures property. By default, enableGestures is set to true.

ej.base.enableRipple(true);
   
   var defaultSidebar = new ej.navigations.Sidebar({
        type: "Push",
        width: '280px',
		enableGestures:false
    });
    defaultSidebar.appendTo('#default-sidebar');
    //end of Sidebar initialization

   // Toggle(Open/Close) the sidebar
    document.getElementById('toggle').onclick = function() {
        defaultSidebar.toggle();
    };

    // Close the sidebar
    document.getElementById('close').onclick = function() {
        defaultSidebar.hide();
    };
    //end of sidebar initialization

    // Toggle(Open/Close) the sidebar
