react-native-masked-text
Advanced tools
This is a simple masked text (normal text and input text) component for React-Native.
React-native: 0.32.0 or higher
npm install react-native-masked-text --save
For all the masks you will use in this way:
import { TextInputMask } from 'react-native-masked-text'
//...
<TextInputMask
type={'type-of-the-mask'}
options={
{
// the options for your mask if needed
}
}
value={this.state.text}
onChangeText={text => {
this.setState({
text: text
})
}}
/>
Mask:
(99) 9999-9999 or (99) 99999-9999 (will detect automatically)+999 999 999 999If you need a different formatting, use the Custom mask =).
Sample code (source):
<TextInputMask
type={'cel-phone'}
options={{
maskType: 'BRL',
withDDD: true,
dddMask: '(99) '
}}
value={this.state.international}
onChangeText={text => {
this.setState({
international: text
})
}}
/>
| name | type | required | default | description |
|---|---|---|---|---|
| maskType | string | no | maskType | the type of the mask to use. Available: BRL or INTERNATIONAL |
| withDDD | boolean | no | true | if the mask type is BRL, include the DDD |
| dddMask | string | no | (99) | if the mask type is BRL, the DDD mask |
You can get the unmasked value using the getRawValue method:
<TextInputMask
type={'cel-phone'}
options={{
maskType: 'BRL',
withDDD: true,
dddMask: '(99) '
}}
value={this.state.international}
onChangeText={text => {
this.setState({
international: text
})
}}
// add the ref to a local var
ref={(ref) => this.phoneField = ref}
/>
//...
const unmasked = this.phoneField.getRawValue()
// in the mask: (51) 98765-4321
// unmasked: 51987654321
Mask: 999.999.999-99
Sample code (source):
<TextInputMask
type={'cpf'}
value={this.state.cpf}
onChangeText={text => {
this.setState({
cpf: text
})
}}
/>
You can check if the cpf is valid by calling the isValid() method:
<TextInputMask
type={'cpf'}
value={this.state.cpf}
onChangeText={text => {
this.setState({
cpf: text
})
}}
// add the ref to a local var
ref={(ref) => this.cpfField = ref}
/>
// get the validation
const cpfIsValid = this.cpfField.isValid()
console.log(cpfIsValid) // boolean
You can get the unmasked cpf calling the getRawValue method:
const unmasked = this.cpfField.getRawValue()
// in the mask: 123.456.789-01
// unmasked: 12345678901
Mask: 99.999.999/9999-99
Sample code (source):
<TextInputMask
type={'cnpj'}
value={this.state.cnpj}
onChangeText={text => {
this.setState({
cnpj: text
})
}}
/>
You can check if the cnpj is valid by calling the isValid() method:
<TextInputMask
type={'cnpj'}
value={this.state.cnpj}
onChangeText={text => {
this.setState({
cnpj: text
})
}}
// add the ref to a local var
ref={(ref) => this.cnpjField = ref}
/>
// get the validation
const cnpjIsValid = this.cnpjField.isValid()
console.log(cnpjIsValid) // boolean
You can get the unmasked cpf calling the getRawValue method:
const unmasked = this.cnpjField.getRawValue()
// in the mask: 99.999.999/9999-99
// unmasked: 99999999999999
Mask:
9999 9999 9999 9999 or 9999 **** **** 9999 (obfuscated)9999 999999 99999 or 9999 ****** 99999 (obfuscated)9999 999999 9999 or 9999 ****** 9999 (obfuscated)Sample code (source)
<TextInputMask
type={'credit-card'}
options={{
obfuscated: false,
issuer: 'amex'
}}
value={this.state.creditCard}
onChangeText={text => {
this.setState({
creditCard: text
})
}}
/>
| name | type | required | default | description |
|---|---|---|---|---|
| obfuscated | boolean | no | false | if the mask should be obfuscated or not |
| issuer | string | no | visa-or-mastercard | the type of the card mask. The options are: visa-or-mastercard, amex or diners |
You can get the array containing the groups of the value value using the getRawValue method:
<TextInputMask
type={'credit-card'}
options={{
obfuscated: false,
issuer: 'amex'
}}
value={this.state.creditCard}
onChangeText={text => {
this.setState({
creditCard: text
})
}}
// add the ref to a local var
ref={(ref) => this.creditCardField = ref}
/>
//...
const unmasked = this.creditCardField.getRawValue()
// in the mask: 9874 6541 3210 9874
// unmasked: [9874, 6541, 3210, 9874]
Mask: defined by pattern
9 - accept digit.A - accept alpha.S - accept alphanumeric.* - accept all, EXCEPT white space.Ex: AAA-9999

| mask | string | YES | The mask pattern | |
| validator | function | no | function that returns true | the function that's validate the value in the mask |
| getRawValue | function | no | return current value | function to parsed value (like unmasked or converted) |
| translation | object (map{string,function}) | no | 9 - digit, A - alpha, S - alphanumeric, * - all, except space | The translator to use in the pattern |
Mask:
DD/MM/YYYY HH:mm:ssDD/MM/YYYYMM/DD/YYYYYYYY/MM/DDHH:mm:ssHH:mmHHYou can use - instead of / if you want.
Sample code (source):
<TextInputMask
type={'datetime'}
options={{
format: 'YYYY/MM/DD'
}}
value={this.state.dt}
onChangeText={text => {
this.setState({
dt: text

format: 'YYYY/MM/DD'
}}
value={this.state.dt}
onChangeText={text => {
this.setState({

You can get the number value of the mask calling the getRawValue method:
<TextInputMask
type={'money'}
value={this.state.simple}
onChangeText={text => {
this.setState({
simple: text
})
}}
// add the ref to a local var
ref={(ref) => this.moneyField = ref}
/>
const numberValue = this.moneyField.getRawValue()
console.log(numberValue) // Number
// CAUTION: the javascript do not support giant numbers.
// so, if you have a big number in this mask, you could have problems with the value...
Mask: accept only numbers
Sample code (source):
<TextInputMask
type={'only-numbers'}
value={this.state.value}
onChangeText={text => {
this.setState({
value: text

}}
/>
Mask: 99999-999
Sample code (source):
<TextInputMask
type={'zip-code'}
value={this.state.value}
onChangeText={text => {
this.setState({
value: text
})
}}
/>
You can get the unmasked value using the getRawValue method:
<TextInputMask
type={'zip-code'}
value={this.state.value}
onChangeText={text => {
this.setState({
value: text
})
}}
// add the ref to a local var
ref={(ref) => this.zipCodeField = ref}
/>
//...
const unmasked = this.zipCodeField.getRawValue()
// in the mask: 98765-321
// unmasked: 98765321
TextInput instanceIf you want to get the TextInput raw component, use the getElement() method:
<TextInputMask
type={'zip-code'}
value={this.state.value}
onChangeText={text => {
this.setState({
value: text
})
}}
// add the ref to a local var
ref={(ref) => this.zipCodeField = ref}
/>
//...
const textInput = this.zipCodeField.getElement()
If you want, you can check the code samples in this repo:
react-native-masked-text-samples
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
}}
/>
)
}
}
The same of TextInputMask, but for React-Native Text component instead TextInput.
Warning: if the value not match the mask, it will not appear.
getElement(): return the instance of Text component.
If you want, we expose the MaskService. You can use it:
