React Masked Field

A masked field component built in React.

The MaskedField component is a text input field that allows you to restrict and format the values that can be entered into it, while informing the user of the expected input. Common uses include dates, phone numbers, social security numbers and tax IDs.

Example

import MaskedField from 'react-masked-field';
 
ReactDOM.render(
  <MaskedField mask="99/99/9999" onComplete={() => console.log('Date is ' + date)} />,
  document.getElementById('demo'),
);

Installation

Install from npm:

npm install react-masked-field

Props

mask?: string

The mask applied to the value of the field. For each character of the mask that matches a translation, the input character will be restricted to the corresponding regular expression. If no mask is provided, it will function like a normal input element.

translations?: { [char: string]: RegExp }

default:

{
  '9': /\d/,
  'a': /[A-Za-z]/,
  '*': /[A-Za-z0-9]/
}

Additional (or overridden) translations for converting mask characters to regular expressions.

onComplete?: (val: string) => void

The onComplete event is triggered when the mask has been completely filled. The value of the field is passed to the event handler.

inputRef?: (node: HTMLInputElement | null) => any

A ref passed to the internal input element.

placeholder?: string

default: the value of the mask prop

This functions just like a normal input placeholder prop. If no placeholder is provided, the mask prop will be used as the placeholder.

Other props

In addition to the props above, MaskedField should handle all supported input props.
