Usage (TextInputMask)

import React, {Component} from 'react';

// import the component
import {TextInputMask} from 'react-native-masked-text';

export default class MyComponent extends Component {
	constructor(props) {
		super(props);
	}

	isValid() {
		// isValid method returns if the inputed value is valid.
		// Ex: if you input 40/02/1990 30:20:20, it will return false
		//	   because in this case, the day and the hour is invalid.
		let valid = this.refs['myDateText'].isValid();
	}

	render() {
		// the type is required but options is required only for some specific types.
		return (
			<TextInputMask 
				ref={'myDateText'}
				type={'datetime'}
				options={{
					format: 'DD-MM-YYYY HH:mm:ss'
				}} />
		);
	}

TextInput Props
You can use the native props of TextInput, with this in mind:

• onChangeText is intercepted by component.
• value is intercepted by component.
• if you pass keyboardType, it will override the keyboardType of masked component.

Options
Some types accept options, use it like this: <TextInputMask type={'money'} options={{ unit: 'US$' }} />

For type={'money'}

• options={...}
  • precision (Number, default 2): the decimal places.
  • separator (String, default ','): the decimal separator.
  • delimiter (String, default '.'): the thousand separator.
  • unit: (String, default 'R$'): the prefix text.
  • suffixUnit (String, default ''): the suffix text.
  • zeroCents (Boolean, default false): if must show cents.

For type={'cel-phone'}

• options={...}
  • withDDD (Boolean, default true): if the ddd will be include in the mask.
  • dddMask (String, default '(99) '): the default mask applied if withDDD is true.

For type={'datetime'}

• options={...}
  • format (String, default DD/MM/YYYY HH:mm:ss): moment date format. It accepts the following:
    • DD/MM/YYYY HH:mm:ss
    • DD/MM/YYYY
    • MM/DD/YYYY
    • YYYY/MM/DD
    • HH:mm:ss
    • HH:mm
    • HH
    • You can use all of dates with - instead of / if you want

  • mask (String, default ''): your mask template.
    • 9: accept digit.
    • A: accept alpha.
    • S: accept alphanumeric.

For type={'credit-card'}

• options={...}

  • credit-card: return true if the mask is complete.
  • cpf: return true if the mask is complete and cpf is valid.
  • cnpj: return true if the mask is complete and cnpj is valid.
  • zip-code: return true if the mask is complete.
  • only-numbers: always returns true.
  • money: always returns true.
  • cel-phone: return true if the mask is complete.
  • datetime: return true if the date value is valid for format.
  • custom: use custom validation, if it not exist, always returns true.

Usage (TextMask)

import React, {Component} from 'react';

// import the component
import {TextMask} from 'react-native-masked-text';

export default class MyComponent extends Component {
	constructor(props) {
		super(props);
		this.state = {
			text: '4567123409871234'
		};
	}

	render() {
		// the type is required but options is required only for some specific types.
		// the sample below will output 4567 **** **** 1234
		return (
			<TextMask 
				value={this.state.text}
				type={'credit-card'}
				options={{
					obfuscated: true
				}} />
		);
	}
}

Props

The same of TextInputMask, but for React-Native Text component instead TextInput.
Warning: if the value not match the mask, it will not appear.

Methods

getElement(): return the instance of Text component.

Extra (MaskService)

If you want, we expose the MaskService. You can use it:

Methods

• static toMask(type, value, settings): mask a value.
  • type (String, required): the type of the mask (cpf, datetime, etc...)
  • value (String, required): the value to be masked
  • settings (Object, optional): if the mask type accepts options, pass it in the settings parameter
• static isValid(type, value, settings): validate if the mask and the value match.
  • type (String, required): the type of the mask (cpf, datetime, etc...)
  • value (String, required): the value to be masked
  • settings (Object, optional): if the mask type accepts options, pass it in the settings parameter

Ex:

import {MaskService} from 'react-native-masked-text'

var money = MaskService.toMask('money', '123', {
	unit: 'US$',
	separator: '.',
	delimiter: ','
});

// money -> US$ 1.23
