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

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/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]/], }, ]} />
Demos
Locale based numbers
When you use as_number or as_percent (and as_currency see below) it will create a mask for you and inherit the locale from the Eufemia Provider, if the locale prop is not given.
You can still define extra mask parameters with number_mask or mask_options, as the second input example shows (e.g. decimalLimit).
<Provider formElement={{ label_direction: 'vertical', }} > <Flex.Vertical> <InputMasked label="Number" as_number mask_options={{ allowNegative: false, }} value="1234.50" on_change={({ numberValue }) => { console.log(numberValue) }} /> <InputMasked label="Number (decimal limit)" as_number number_mask={{ decimalLimit: 2, }} value="1234.016" on_change={({ numberValue }) => { console.log(numberValue) }} /> <InputMasked label="Percentage" as_percent number_mask={{ decimalLimit: 1, }} value="1234.016" on_change={({ numberValue }) => { console.log(numberValue) }} /> </Flex.Vertical> </Provider>
Locale based as_currency
When you use as_currency it will create a mask for you and inherit the locale from the Eufemia Provider, if the locale prop is not given.
<Provider formElement={{ label_direction: 'vertical', }} > <Flex.Vertical> <InputMasked label="Currency" as_currency="EUR" value="1234.50" on_change={({ numberValue }) => { console.log(numberValue) }} /> <Provider locale="en-GB" InputMasked={{ currency_mask: { decimalLimit: 3, }, }} > <InputMasked label="Currency" as_currency="USD" value="1234.567" on_change={({ numberValue }) => { console.log(numberValue) }} /> </Provider> </Flex.Vertical> </Provider>
Define the currency_mask manually
<Provider formElement={{ label_direction: 'vertical', }} > <Flex.Vertical> <InputMasked label="Left aligned (default)" show_mask currency_mask="kr" on_change={({ numberValue }) => { console.log(numberValue) }} /> <InputMasked label="Right aligned" show_mask currency_mask={{ currency: 'NOK', }} align="right" on_change={({ numberValue }) => { console.log(numberValue) }} /> </Flex.Vertical> </Provider>
Customize the number mask
<InputMasked label="Masked amount" show_mask number_mask={{ suffix: ' kr', allowDecimal: true, }} placeholder_char={null} on_change={({ numberValue }) => { console.log(numberValue) }} />
Using the number_mask with a combined suffix
<InputMasked label="Masked input" value="1000000" number_mask={{ suffix: ',-', allowDecimal: false, }} suffix="kr" on_change={({ numberValue }) => { console.log(parseInt(numberValue || 0, 10)) }} />
Using the number_mask and a prefix
<InputMasked label="Masked input" number_mask={{ prefix: 'NOK ', }} stretch={true} placeholder="Enter a number" on_change={({ numberValue }) => { console.log(numberValue) }} />
Custom mask
This is an example of how you can utilize a custom mask.
For a phone number input, use the PhoneNumber field instead.
<InputMasked label="Custom mask" mask={[ '0', '0', /[4]/, // have to start with 4 /[5-7]/, // can be 5,6 or 7 ' ', /[49]/, // have to start with 4 or 9 /\d/, ' ', /\d/, /\d/, ' ', /\d/, /\d/, ' ', /\d/, /\d/, ]} show_mask placeholder_char="_" keep_char_positions on_change={({ numberValue }) => { console.log(numberValue) }} />
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/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]/], }, ]} />
