#InputMasked

#Description

The InputMasked component uses the basic Input component, but with some additional masking functionality.

#How it works

This component uses the basic Input but with a set of options and features.

You will either create your own mask, or use one of the provided once. There are also masks which change based on different locales (as_currency or as_number).

#Accessibility

Screen readers will read also the mask before the user is entering the content. Also, the user will hear the mask during typing. This behavior can both have positive and negative side effects on the user. But overall, it works ok.

Both entering a comma or a dot will act as a decimal separator if decimals are enabled and one of the internal masks for numbers is used.

#InputMode

NB: Please do not set inputMode="numeric" or inputMode="decimal", because devices may or may not show a minus key (-)!

The InputMasked component does handle soft keyboards (iOS and Android) by using either inputMode="numeric" and inputMode="decimal" depending on allowNegative and allowDecimal (getSoftKeyboardAttributes).

For iOS it additionally sets type="number" during focus (InputModeNumber). This way the correct numeric soft keyboard is shown.

<InputMasked
  mask_options={{
    allowNegative: false,
  }}
/>

#Mask based on locale

The InputMasked component supports masks based on a given locale. The locale will be inherited from the Eufemia Provider if not given.

As of now, you can enable these masks by giving:

• as_currency="EUR"
• as_number={true}

You can still send in custom mask parameters to currency_mask={{ ... }} or number_mask={{ ... }}. But you can also make use of mask_options={{ ... }} and just send in your extra options in there.

More details in the examples above.

#Clean number values

If you use as_currency or as_number you have to always send in in a clean number without any mask (value="1234.50"):

<InputMasked as_currency="EUR" value="1234.50" />

You can also receive a clean number value you can use and send back in again:

<InputMasked
  as_currency="EUR"
  value="1234.50"
  on_change={({ numberValue }) => {
    console.log(numberValue) // type of float
  }}
/>

#Decimals

• number_mask will default to no decimals
• currency_mask will default to no decimals
• as_number will default to no decimals
• as_currency will default to 2 decimals

You can change the number of decimals by sending in options to the currency_mask, number_mask, or mask_options (see example above).

This example here also shows how to affect every InputMasked component in your application, by setting these options on the Eufemia Provider.

<Provider
  locale="en-GB"
  InputMasked={{
    currency_mask: {
      decimalLimit: 1, // defaults to 2
    },
  }}
>
  <InputMasked as_currency="USD" value="1234.567" />
</Provider>

<Provider
  locale="en-GB"
  InputMasked={{
    number_mask: {
      decimalLimit: 2, // defaults to no decimals
    },
  }}
>
  <InputMasked as_number value="1234.567" />
</Provider>

To remove a decimal limit, you can send in null and allow decimals with allowDecimal:

<InputMasked
  as_number
  mask_options={{
    allowDecimal: true,
    decimalLimit: null,
  }}
  value="1234.567"
/>

#Mask with multiple inputs

Allows for the same input functionality as in the DatePicker, but with your own defined inputs. onChange takes an object with keys based on the step id's. e.g. {month: string, year: string, suffix: string}

import as demonstrated below

import { MultiInputMask } from '@dnb/eufemia/src/components/input-masked'
render(<MultiInputMask />)

<MultiInputMask
  label="Date"
  delimiter="/"
  onChange={({ month, year, suffix }) =>
    console.log({
      month,
      year,
      suffix,
    })
  }
  inputs={[
    {
      id: 'month',
      label: 'the month',
      placeholderCharacter: 'd',
      mask: [/[0-9]/, /[0-9]/],
    },
    {
      id: 'year',
      label: 'the year',
      placeholderCharacter: 'm',
      mask: [/[0-9]/, /[0-9]/],
    },
    {
      id: 'suffix',
      label: 'suffix text',
      placeholderCharacter: '-',
      mask: [/[a-zA-Z]/, /[a-zA-Z]/, /[a-zA-Z]/],
    },
  ]}
/>
