# Number Input URL: https://ark-ui.com/docs/components/number-input Source: https://raw.githubusercontent.com/chakra-ui/ark/refs/heads/main/website/src/content/pages/components/number-input.mdx A field that allows user input of numeric values. --- ## Anatomy To set up the number input correctly, you'll need to understand its anatomy and how we name its parts. > Each part includes a `data-part` attribute to help identify them in the DOM. ## Examples Learn how to use the `NumberInput` component in your project. Let's take a look at the most basic example: **Example: basic** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const Basic = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const Basic = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Count - + ``` ### Setting a minimum and maximum value Pass the `min` prop or `max` prop to set an upper and lower limit for the input. By default, the input will restrict the value to stay within the specified range. **Example: min-max** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const MinMax = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const MinMax = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Adjusting the precision of the value In some cases, you might need the value to be rounded to specific decimal points. Set the `formatOptions` and provide `Intl.NumberFormatOptions` such as `maximumFractionDigits` or `minimumFractionDigits`. **Example: fraction-digits** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const FractionDigits = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const FractionDigits = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Scrubbing the input value The NumberInput supports the scrubber interaction pattern. To use this pattern, render the `NumberInput.Scrubber` component. It uses the Pointer lock API and tracks the pointer movement. It also renders a virtual cursor which mimics the real cursor's pointer. **Example: scrubber** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const Scrubber = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const Scrubber = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Using the mouse wheel to change value The NumberInput exposes a way to increment/decrement the value using the mouse wheel event. To activate this, set the `allowMouseWheel` prop to `true`. **Example: mouse-wheel** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const MouseWheel = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const MouseWheel = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Clamp value when user blurs the input In most cases, users can type custom values in the input field. If the typed value is greater than the max, the value is reset to max when the user blur out of the input. To disable this behavior, pass `clampValueOnBlur` and set to `false`. **Example: no-clamp** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const NoClamp = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const NoClamp = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Usage within forms To use the number input within forms, set the `name` prop. **Example: form-usage** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const FormUsage = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const FormUsage = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Format and parse value To apply custom formatting to the input's value, set the `formatOptions` and provide `Intl.NumberFormatOptions` such as `style` and `currency`. **Example: formatted** #### React ```tsx import { NumberInput } from '@ark-ui/react/number-input' export const Formatted = () => ( Label -1 +1 ) ``` #### Solid ```tsx import { NumberInput } from '@ark-ui/solid/number-input' export const Formatted = () => ( Label -1 +1 ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 ``` ### Using the Field Component The `Field` component helps manage form-related state and accessibility attributes of a number input. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility. **Example: with-field** #### React ```tsx import { Field } from '@ark-ui/react/field' import { NumberInput } from '@ark-ui/react/number-input' export const WithField = (props: Field.RootProps) => ( Label -1 +1 Additional Info Error Info ) ``` #### Solid ```tsx import { Field } from '@ark-ui/solid/field' import { NumberInput } from '@ark-ui/solid/number-input' export const WithField = (props: Field.RootProps) => ( Label -1 +1 Additional Info Error Info ) ``` #### Vue ```vue ``` #### Svelte ```svelte Label -1 +1 Additional Info Error Info ``` ### Using the Root Provider The `RootProvider` component provides a context for the number-input. It accepts the value of the `useNumber-input` hook. You can leverage it to access the component state and methods from outside the number-input. **Example: root-provider** #### React ```tsx import { NumberInput, useNumberInput } from '@ark-ui/react/number-input' export const RootProvider = () => { const numberInput = useNumberInput() return ( <> Label -1 +1 ) } ``` #### Solid ```tsx import { NumberInput, useNumberInput } from '@ark-ui/solid/number-input' export const RootProvider = () => { const numberInput = useNumberInput() return ( <> Label -1 +1 ) } ``` #### Vue ```vue ``` #### Svelte ```svelte Count - + ``` > If you're using the `RootProvider` component, you don't need to use the `Root` component. ## Guides ### Using the Scrubber The `NumberInput.Scrubber` component provides an interactive scrub area that allows users to drag to change the input value. It renders as a `
` element and displays a custom cursor element during scrubbing interactions. This component utilizes the [Pointer Lock API](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API) for smooth dragging interactions. > **Note:** Browsers may show a notification when the Pointer Lock API is activated. The scrubber is automatically > disabled in Safari to prevent layout shifts. ### Controlling the value When controlling the NumberInput component, it's recommended to use string values instead of converting to numbers. This is especially important when using `formatOptions` for currency or locale-specific formatting. ```tsx const [value, setValue] = useState('0') setValue(details.value)}> {/* ... */} ``` Converting values to numbers can cause issues with locale-specific formatting, particularly for currencies that use different decimal and thousands separators (e.g., `1.523,30` vs `1,523.30`). By keeping values as strings, you preserve the correct formatting and avoid parsing issues. If you need to submit a numeric value in your form, use a hidden input that reads `valueAsNumber` from `NumberInput.Context`: ```tsx setValue(details.value)}> {(context) => } ``` ## API Reference ### Props **Component API Reference** #### React **Root Props:** | Prop | Type | Required | Description | |------|------|----------|-------------| | `allowMouseWheel` | `boolean` | No | Whether to allow mouse wheel to change the value | | `allowOverflow` | `boolean` | No | Whether to allow the value overflow the min/max range | | `asChild` | `boolean` | No | Use the provided child element as the default rendered element, combining their props and behavior. | | `clampValueOnBlur` | `boolean` | No | Whether to clamp the value when the input loses focus (blur) | | `defaultValue` | `string` | No | The initial value of the input when rendered.
