react-native-masked-text
Advanced tools
This is a simple masked text (normal text and input text) component for React-Native.
Thanks to vanilla-masker =). Thanks to moment =).
React-native: 0.32.0 or higher
npm install react-native-masked-text --save
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.myDateText.isValid();
// get converted value. Using type=datetime, it returns the moment object.
// If it's using type=money, it returns a Number object.
let rawValue = this.myDateText.getRawValue();
}
render() {
// the type is required but options is required only for some specific types.
return (
<TextInputMask
refInput={(ref) => this.myDateText = ref;}
type={'datetime'}
options={{
format: 'DD-MM-YYYY HH:mm:ss'
}}
/>
)
}
}
credit-card: use the mask 9999 9999 9999 9999. It accepts options (see later in this doc).
cpf: use the mask 999.999.999-99 and numeric keyboard.
cnpj: use the mask 99.999.999/9999-99 and numeric keyboard.
zip-code: use the mask 99999-999 and numeric keyboard.
only-numbers: accept only numbers on field with numeric keyboard.
money: use the mask R$ 0,00 on the field with numeric keyboard. It accepts options (see later in this doc).
cel-phone: use the mask (99) 9999-9999 or (99) 99999-9999 (changing automaticaly by length). It accepts options (see later in this doc).
datetime: use datetime mask with moment format (default DD/MM/YYYY HH:mm:ss). It accepts options (see later in this doc).
custom: use your custom mask (see the options props later in this doc).
Invoked after new value applied to mask.
/**
* @param {String} text the text AFTER mask is applied.
*/
onChangeText(text) {
// ...
}
<TextInputMask
type={'only-numbers'}
onChangeText={this.onChangeText.bind(this)} />
Allow you to check and prevent value to be inputed.
/**
* @param {String} previous the previous text in the masked field.
* @param {String} next the next text that will be setted to field.
* @return {Boolean} return true if must accept the value.
*/
checkText(previous, next) {
return next === 'your valid value or other boolean condition';
}
<TextInputMask
type={'only-numbers'}
checkText={this.checkText.bind(this)} />
You can use this prop if you want custom text input instead native TextInput component:
const Textfield = MKTextField.textfield()
.withPlaceholder('Text...')
.withStyle(styles.textfield)
.build();
<TextInputMask
refInput={(ref) => this.myDateText = ref;}
type={'money'}
style={styles.input}
customTextInput={Textfield}
placeholder="Enter text to see events"
/>
Some custom inputs like react-native-textinput-effects have to set properties in mount time. For these types of components we use this property.
import React from 'react'
import { StyleSheet, View } from 'react-native'
import { TextInputMask } from 'react-native-masked-text'
import { Kaede } from 'react-native-textinput-effects'
export default class App extends React.Component {
constructor(props) {
super(props)
this.state = {
birthday: ''
}
}
render() {
return (
<View style={styles.container}>
<TextInputMask
refInput={(ref) => this.myDateText = ref;}
// here we set the custom component and their props.
customTextInput={Kaede}
customTextInputProps={{
style:{ width: '80%' },
label:'Birthday'
}}
type={'datetime'}
options={{
format: 'DD-MM-YYYY HH:mm:ss'
}}
// don't forget: the value and state!
onChangeText={birthday => this.setState({ birthday })}
value={this.state.birthday} />
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center'
}
})
You can use the native props of TextInput, with this in mind:
If you want to use the methods of the native TextInput, use the getElement() method:
export default class App extends React.Component {
onGoFocus() {
// when you call getElement method, the instance of native TextInput will returned.
this.refs['myText'].getElement().focus()
}
render() {
return (
<View style={styles.container}>
<View>
<TextInputMask
ref="myText"
type={'only-numbers'}
style={styles.input}
/>
</View>
<View>
<Button
onPress={this.onGoFocus.bind(this)}
title="Go Focus Hue"
color="#841584"
/>
</View>
</View>
)
}
}
Some types accept options, use it like this: <TextInputMask type={'money'} options={{ unit: 'US$' }} />
For type={'money'}
precision (Number, default 2): the decimal places.
_ separator (String, default ','): the decimal separator.
_ delimiter (String, default '.'): the thousand separator.
_ unit: (String, default 'R$'): the prefix text.
_ suffixUnit (String, default ''): the suffix text.
_ zeroCents (Boolean, default false): if must show cents.For type={'cel-phone'}
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'}
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 wantFor type={'custom'}
{
/**
* mask: (String | required | default '')
* the mask pattern
* 9 - accept digit.
* A - accept alpha.
* S - accept alphanumeric.
* * - accept all, EXCEPT white space.
*/
mask: '999#AAA',
/**
* validator: (Function | optional | defaults returns true)
* use this funcion to inform if the inputed value is a valid value (for invalid phone numbers, for example). The isValid method use this validator.
*/
validator: function(value, settings) {
return true
},
/**
* getRawValue: (Function | optional | defaults return current masked value)
* use this function to parse and return values to use what you want.
* for example, if you want to create a phone number mask (999) 999-99-99 but want to get only
* the numbers for value, use this method for this parse step.
*/
getRawValue: function(value, settings) {
return 'my converted value';
},
/**
* translation: (Object | optional | defaults 9, A, S, *)
* the dictionary that translate mask and value.
* you can change defaults by simple override the key (9, A, S, *) or create some new.
*/
translation: {
// this is a custom translation. The others (9, A, S, *) still works.
// this translation will be merged and turns into 9, A, S, *, #.
'#': function(val) {
if (val === ' ') {
return val;
}
// if returns null, undefined or '' (empty string), the value will be ignored.
return null;
},
// in this case, we will override build-in * translation (allow all characters)
// and set this to allow only blank spaces and some special characters.
'*': function(val) {
return [' ', '#', ',', '.', '!'].indexOf(val) >= 0 ? val : null;
}
}

obfuscated (Boolean, default false): if the mask must be 9999 **** **** 9999getElement(): return the instance of TextInput component.isValid(): if the value inputed is valid for the mask. * 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.getRawValue(): get the converted value of mask. * credit-card: return the array with the value parts.

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:
Methods
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 parametertype (String, required): the type of the mask (cpf, datetime, etc...)
_ maskedValue (String, required): the masked value to be converted in raw value * settings (Object, optional): if the mask type accepts options, pass it in the settings parametertype (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 parameterEx:
import { MaskService } from 'react-native-masked-text'
var money = MaskService.toMask('money', '123', {
unit: 'US$',
separator: '.',
delimiter: ','
})
// money -> US$ 1.23
