13 Jun 20248 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.

Dependencies

The list of dependencies required to use the OTP Input control in your application is given as follows:

|-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-base

Control Initialization

The JavaScript (ES5) OTP Input control can be initialized by using either of the following ways.

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 quickstart for getting started.

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

Syntax:

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

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

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

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

Example:

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

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

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

Control Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-inputs\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

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific controls. This web tool is useful to combine the required control scripts and styles in a single file.

Step 3: Create a folder ~/quickstart/resources and copy/paste the global scripts and styles from the above installed location to ~/quickstart/resources/package corresponding package location.

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

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
            <title>JavaScript (ES5)</title>
            <!-- JavaScript (ES5) OTP Input's dependency style -->
            <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>

            <!-- JavaScript (ES5) OTP Input's control style -->
            <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

            <!-- JavaScript (ES5) OTP Input's dependency global script -->
            <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>

            <!-- JavaScript (ES5) OTP Input's control global script -->
            <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

Step 5: Now, add the OTP Input element and initiate the JavaScript (ES5) OTP Input control in the index.html by using following code

[src/index.html]

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
          <title>JavaScript (ES5)</title>
          <!-- JavaScript (ES5) OTP Input's dependency style -->
          <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) OTP Input's control style -->
          <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) OTP Input's dependency global script -->
          <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>

          <!-- JavaScript (ES5) OTP Input's control global script -->
          <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!-- Add the HTML <div> element  -->
          <div class="otp-container" style="width: 350px;">
               <div id="otp_default"></div>
          </div>
          <script>
               // Initializes the OTP Input control
               var otpInput = new ej.inputs.OtpInput({});

               // Render initialized OTP Input.
               otpInput.appendTo('#otp_default');
          </script>
       </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript (ES5) OTP Input control.

Using CDN link for script and style reference

Step 1: Create an app folder quickstart for getting started.

Step 2: The JavaScript (ES5) control’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Dependency Script: https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

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

Dependency Styles: https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/styles/material.css

Control Styles: https://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: https://cdn.syncfusion.com/ej2/ej2-inputs/dist/global/ej2-inputs.min.js

Styles: https://cdn.syncfusion.com/ej2/ej2-inputs/styles/material.css

Step 3: Create a HTML page (index.html) in ~/quickstart/index.html location and add the CDN link references. Now, add the OTP Input element and initiate the JavaScript (ES5) OTP Input control in the index.html by using following code.

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

<head>
  <script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js"></script>
  <title>JavaScript (ES5)</title>
  <!-- JavaScript (ES5) OTP Input's dependency style -->
  <link href="https://cdn.syncfusion.com/ej2/28.1.33/ej2-base/styles/material.css" rel="stylesheet" type="text/css" />

  <!-- JavaScript (ES5) OTP Input's control style -->
  <link href="https://cdn.syncfusion.com/ej2/28.1.33/ej2-inputs/styles/material.css" rel="stylesheet" type="text/css" />

  <!-- JavaScript (ES5) OTP Input's dependency global script -->
  <script src="https://cdn.syncfusion.com/ej2/28.1.33/ej2-base/dist/global/ej2-base.min.js" type="text/javascript"></script>

  <!-- JavaScript (ES5) OTP Input's control global script -->
  <script src="https://cdn.syncfusion.com/ej2/28.1.33/ej2-inputs/dist/global/ej2-inputs.min.js" type="text/javascript"></script>

  <!--style reference from app-->
  <link href="index.css" rel="stylesheet" />
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>

<body>
  <!--Element to render the OTP Input control-->
  <div id='container' style="width: 350px;">
    <div id="otp_default"></div>
  </div>
  <script>
    // Initializes the OTP Input control
    var otpInput = new ej.inputs.OtpInput({});

    // Render initialized OTP Input.
    otpInput.appendTo('#otp_default');
  </script>
  <script>
    var ele = document.getElementById('container');
    if (ele) {
      ele.style.visibility = "visible";
    }   
  </script>
</body>

</html>
#container {
  visibility: hidden;
  margin: 50px auto;
  width: 350px;
}

#loader {
  color: #008cff;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}

Step 4: Now, run the index.html in web browser, it will render the Syncfusion JavaScript OTP Input control.
