Placeholder in EJ2 TypeScript OTP Input control

18 Jul 20245 minutes to read

The placeholder in OTP Input specifies the text that is shown as a hint or placeholder until the user enters a value in the input field. It acts as a guidance for the users regarding the expected input format or purpose of the input field.

You can set the placeholder text by using the placeholder property. Additionally, when providing a single character as the placeholder value all input fields within the OTP Input control will display the same character.

index.ts
index.html
index.css
import { OtpInput } from "@syncfusion/ej2-inputs";

// Initializes the OTP Input control
let otpInput: OtpInput = new OtpInput({
    placeholder: "x"
});

// Render initialized OTP Input.
otpInput.appendTo('#default_otp');

#container {
  visibility: hidden;
  margin: 50px auto;

#loader {

  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}

When a placeholder with multiple placeholder characters is provided each input field will display characters from the placeholder string in sequence based on the available OTP input length.

index.ts
index.html
index.css
import { OtpInput } from "@syncfusion/ej2-inputs";

// Initializes the OTP Input control
let otpInput: OtpInput = new OtpInput({
    placeholder: "wxyz"
});

// Render initialized OTP Input.
otpInput.appendTo('#default_otp');
