InputMask component is used to enter input in a certain format such as numeric, date, currency, email and phone.

import { InputMask } from 'primereact/inputmask';

InputMask is used as a controlled input with value and onChange properties along with the mask property to define the mask.

<InputMask value={value} onChange={(e) => setValue(} mask="99-999999" placeholder="99-999999" />

Mask format can be a combination of the following definitions; a for alphabetic characters, 9 for numeric characters and * for alphanumberic characters. In addition, formatting characters like ( , ) , - are also accepted.

<label htmlFor="ssn" className="font-bold block mb-2">SSN</label>
<InputMask id="ssn" mask="999-99-9999" placeholder="999-99-9999"></InputMask>

<label htmlFor="phone" className="font-bold block mb-2">Phone</label>
<InputMask id="phone" mask="(999) 999-9999" placeholder="(999) 999-9999"></InputMask>

<label htmlFor="serial" className="font-bold block mb-2">Serial</label>
<InputMask id="serial" mask="a*-999-a999" placeholder="a*-999-a999"></InputMask>

When the input does not complete the mask definition, it is cleared by default. Use autoClear property to control this behavior. In addition, ? is used to mark anything after the question mark optional.

<InputMask value={value} onChange={(e) => setValue(} mask="(999) 999-9999? x99999" placeholder="(999) 999-9999? x99999"  />

Default placeholder for a mask is underscore that can be customized using slotChar property.

<InputMask value={value} onChange={(e) => setValue(} mask="99/99/9999" placeholder="99/99/9999" slotChar="mm/dd/yyyy" />

A floating label appears on top of the input field when focused.

<span className="p-float-label">
    <InputMask id="ssn_input" value={value} onChange={(e) => setValue(} mask="999-99-9999" />
    <label htmlFor="ssn_input">SSN</label>

Invalid state style is added using the p-invalid class to indicate a failed validation.

<InputMask mask="99-999999" placeholder="99-999999" className="p-invalid"/>

When disabled is present, the element cannot be edited and focused.

<InputMask mask="99-999999" placeholder="99-999999" disabled />
