InputMask

This component is a wrapper that allows you to set the format for the input value.

Mask

This is an example of a basic input with a mask feature. The mask is defined using the mask property, which specifies the input format and validates the entered value.

TIP

Remember to set the placeholder for the input field to match the mask. Typically, the placeholder should be the same as the mask itself.

tsx

import React from 'react';
import InputMask from 'intergalactic/input-mask';
import { Text } from 'intergalactic/typography';
import { Flex } from 'intergalactic/flex-box';

const Demo = () => {
  return (
    <Flex direction='column' gap={2} w={224}>
      <Text tag='label' htmlFor='basic-example' size={200}>
        Card number
      </Text>
      <InputMask w={224}>
        <InputMask.Value
          mask='9999 9999 9999 9999'
          placeholder='____ ____ ____ ____'
          title='16-digit number'
          id='basic-example'
          aria-describedby='basic-example-hint'
        />
      </InputMask>
      <Text size={100} color='gray-500' id='basic-example-hint'>
        Please enter the 16-digit number of your debit card.
      </Text>
    </Flex>
  );
};

export default Demo;

import React from 'react';
import InputMask from 'intergalactic/input-mask';
import { Text } from 'intergalactic/typography';
import { Flex } from 'intergalactic/flex-box';

const Demo = () => {
  return (
    <Flex direction='column' gap={2} w={224}>
      <Text tag='label' htmlFor='basic-example' size={200}>
        Card number
      </Text>
      <InputMask w={224}>
        <InputMask.Value
          mask='9999 9999 9999 9999'
          placeholder='____ ____ ____ ____'
          title='16-digit number'
          id='basic-example'
          aria-describedby='basic-example-hint'
        />
      </InputMask>
      <Text size={100} color='gray-500' id='basic-example-hint'>
        Please enter the 16-digit number of your debit card.
      </Text>
    </Flex>
  );
};

export default Demo;

Aliases

aliases is the object that defines how characters in the mask are validated. By default, they are configured as follows:

9 - numbers
a - Latin and Cyrillic letters in any case
* - numbers and Latin and Cyrillic letters in any case

tsx

import React from 'react';
import InputMask from 'intergalactic/input-mask';
import { Text } from 'intergalactic/typography';
import { Flex } from 'intergalactic/flex-box';

const Demo = () => {
  const [value, setValue] = React.useState('99');

  return (
    <Flex direction='column' gap={2} w={224}>
      <Text tag='label' htmlFor='aliases-example' size={200}>
        Item index
      </Text>
      <InputMask w={224}>
        <InputMask.Value
          id='aliases-example'
          aliases={{ x: /[0-9]/ }}
          mask='99xxxx'
          value={value}
          onChange={setValue}
          aria-describedby='aliases-example-hint'
          title='4-digit number'
        />
      </InputMask>
      <Text size={100} color='gray-500' id='aliases-example-hint'>
        Write any 4 digits and after
      </Text>
    </Flex>
  );
};

export default Demo;

import React from 'react';
import InputMask from 'intergalactic/input-mask';
import { Text } from 'intergalactic/typography';
import { Flex } from 'intergalactic/flex-box';

const Demo = () => {
  const [value, setValue] = React.useState('99');

  return (
    <Flex direction='column' gap={2} w={224}>
      <Text tag='label' htmlFor='aliases-example' size={200}>
        Item index
      </Text>
      <InputMask w={224}>
        <InputMask.Value
          id='aliases-example'
          aliases={{ x: /[0-9]/ }}
          mask='99xxxx'
          value={value}
          onChange={setValue}
          aria-describedby='aliases-example-hint'
          title='4-digit number'
        />
      </InputMask>
      <Text size={100} color='gray-500' id='aliases-example-hint'>
        Write any 4 digits and after
      </Text>
    </Flex>
  );
};

export default Demo;

Pipe

pipe is a function that processes and changes the InputMask value after user input.

In the example below, it is used for formatting and validating the card's expire date input. The focus is switched to the next input by the onSucces event. It is called when the entered value fully matches the input mask.

tsx

import React from 'react';
import { Box, Flex } from 'intergalactic/flex-box';
import { Text } from 'intergalactic/typography';
import InputMask from 'intergalactic/input-mask';

const Demo = () => {
  const expireDateInput = React.useRef(null);
  const handleSuccess = React.useCallback(() => expireDateInput.current.focus(), []);

  return (
    <Box wMax={225} p={8} m='0 auto' style={{ borderRadius: '12px', background: '#F4F5F9' }}>
      <Text
        tag='label'
        size={300}
        medium
        mb={2}
        htmlFor='card_number'
        style={{ display: 'inline-block' }}
      >
        Card number
      </Text>
      <InputMask size='l' mb={4}>
        <InputMask.Value
          mask='9999 9999 9999 9999'
          placeholder='____ ____ ____ ____'
          onSuccess={handleSuccess}
          title='card number - 16-digits'
          id='card_number'
        />
      </InputMask>
      <Flex alignItems='center' justifyContent='flex-end'>
        <Text tag='label' mr={2} size={300} htmlFor='expire_date'>
          Expire date
        </Text>
        <InputMask size='l' wMax={85}>
          <InputMask.Value
            ref={expireDateInput}
            mask='99/99'
            placeholder='MM/YY'
            pipe={pipeExpireDate}
            title='month and year of card expiration - 4 digits in total'
            id='expire_date'
          />
        </InputMask>
      </Flex>
    </Box>
  );
};

const pipeExpireDate = (value) => {
  const indexesOfPipedChars = [];
  const firstMonthDigit = parseInt(value[0], 10);
  if (firstMonthDigit > 1) {
    value = `0${value[0]}/${value.split('/')[1]}`;
    indexesOfPipedChars.push(0);
  }
  const [month, year] = value
    .split('/')
    .map((chunk) => (chunk.includes('_') ? undefined : parseInt(chunk, 10)));
  const currentYear = new Date().getFullYear() % 100;
  const currentMonth = new Date().getMonth() + 1;

  if (month > 12) return false;
  if (year === currentYear && month < currentMonth) return false;
  if (year < currentYear) return false;

  return { value, indexesOfPipedChars };
};
