Features#

Number fields can be built with <input type="number">, but the behavior is very inconsistent across browsers and platforms, it supports limited localized formatting options, and it is challenging to style the stepper buttons. NumberField helps achieve accessible number fields that support internationalized formatting options and can be styled as needed.

Customizable formatting – Support for internationalized number formatting and parsing including decimals, percentages, currency values, and units. Multiple currency formats are supported, including symbol, code, and name in standard or accounting notation.
International – Support for the Latin, Arabic, Devanagari, Bengali, and Han positional decimal numbering systems in over 30 locales. The numbering system is automatically detected from user input, and input method editors such as Pinyin are supported.
Validation – Keyboard input is validated as the user types so that only numeric input is accepted, according to the locale and numbering system. Values are automatically rounded and clamped according to configurable decimal, minimum, maximum, and step values. Custom client and server-side validation is also supported.
Mobile friendly – An appropriate software keyboard is automatically selected based on the allowed values for ease of use.
Accessible – Follows the spinbutton ARIA pattern, with support for arrow keys, scroll wheel, and stepper buttons to increment and decrement the value. Extensively tested across many devices and assistive technologies to ensure announcements and behaviors are consistent.

Read our blog post for more details about the interactions and internationalization support implemented by NumberField.

Anatomy#

Number fields consist of an input element that shows the current value and allows the user to type a new value, optional stepper buttons to increment and decrement the value, a group containing the input and stepper buttons, and a label.

NumberField also supports optional description and error message elements, which can be used to provide more context about the field, and any validation messages. These are linked with the input via the aria-describedby attribute.

import {Button, FieldError, Group, Input, Label, NumberField, Text} from 'react-aria-components';

<NumberField>
  <Label />
  <Group>
    <Input />
    <Button slot="increment" />
    <Button slot="decrement" />
  </Group>
  <Text slot="description" />
  <FieldError />
</NumberField>

import {
  Button,
  FieldError,
  Group,
  Input,
  Label,
  NumberField,
  Text
} from 'react-aria-components';

<NumberField>
  <Label />
  <Group>
    <Input />
    <Button slot="increment" />
    <Button slot="decrement" />
  </Group>
  <Text slot="description" />
  <FieldError />
</NumberField>

import {
  Button,
  FieldError,
  Group,
  Input,
  Label,
  NumberField,
  Text
} from 'react-aria-components';

<NumberField>
  <Label />
  <Group>
    <Input />
    <Button slot="increment" />
    <Button slot="decrement" />
  </Group>
  <Text slot="description" />
  <FieldError />
</NumberField>

If there is no visual label, an aria-label or aria-labelledby prop must be passed instead to identify the element to screen readers.

Concepts#

NumberField makes use of the following concepts:

Forms

Validating and submitting form data, and integrating with form libraries.

Composed components#

A NumberField uses the following components, which may also be used standalone or reused in other components.

Label

A label provides context for an input element.

Input

An input allows a user to enter a plain text value with a keyboard.

Button

A button allows a user to perform an action.

Starter kits#

To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured Storybook that you can experiment with, or use as a starting point for your own component library.

Reusable wrappers#

If you will use a NumberField in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.

This example wraps NumberField and all of its children together into a single component which accepts a label prop, which is passed to the right place. It also shows how to use the description slot to render help text, and FieldError component to render validation errors.

import type {NumberFieldProps, ValidationResult} from 'react-aria-components';
import {FieldError, Text} from 'react-aria-components';

interface MyNumberFieldProps extends NumberFieldProps {
  label?: string;
  description?: string;
  errorMessage?: string | ((validation: ValidationResult) => string);
}

function MyNumberField(
  { label, description, errorMessage, ...props }: MyNumberFieldProps
) {
  return (
    <NumberField {...props}>
      <Label>{label}</Label>
      <Group>
        <Button slot="decrement">-</Button>
        <Input />
        <Button slot="increment">+</Button>
      </Group>
      {description && <Text slot="description">{description}</Text>}
      <FieldError>{errorMessage}</FieldError>
    </NumberField>
  );
}

        {errorMessage}
      </FieldError>
    </NumberField>
  );
}

Value#

Controlled#

By default, NumberField is uncontrolled. However, when using the value prop, it becomes controlled. This allows you to store the current value in your own state, and use it elsewhere.

The onChange event is triggered whenever the number value updates. This happens when the user types a value and blurs the input, or when incrementing or decrementing the value. It does not happen as the user types because partial input may not be parseable to a valid number.

function Example() {
  let [value, setValue] = React.useState(6);

  return (
    <>
      <MyNumberField
        label="Controlled value"
        value={value}
        onChange={setValue} />
      <div>Current value prop: {value}</div>
    </>
  );
}

function Example() {
  let [value, setValue] = React.useState(6);

  return (
    <>
      <MyNumberField
        label="Controlled value"
        value={value}
        onChange={setValue} />
      <div>Current value prop: {value}</div>
    </>
  );
}

function Example() {
  let [value, setValue] =
    React.useState(6);

  return (
    <>
      <MyNumberField
        label="Controlled value"
        value={value}
        onChange={setValue}
      />
      <div>
        Current value
        prop: {value}
      </div>
    </>
  );
}

HTML forms#

NumberField supports the name prop for integration with HTML forms. The value will be submitted to the server as a raw number (e.g. 45), not as a locale-dependent formatted string (e.g. "$45.00").

<MyNumberField
  label="Transaction amount"
  name="amount"  defaultValue={45}
  formatOptions={{
    style: 'currency',
    currency: 'USD'
  }} />

<MyNumberField
  label="Transaction amount"
  name="amount"  defaultValue={45}
  formatOptions={{
    style: 'currency',
    currency: 'USD'
  }} />

<MyNumberField
  label="Transaction amount"
  name="amount"  defaultValue={45}
  formatOptions={{
    style: 'currency',
    currency: 'USD'
  }}
/>

Number formatting#

Decimals#

The default formatting style for NumberField is decimal, but you can configure various aspects via the formatOptions prop. All options supported by Intl.NumberFormat are supported, including configuration of minimum and maximum fraction digits, sign display, grouping separators, etc. Currently only standard notation is supported, though scientific, engineering, and compact notation may be supported in the future.

The following example uses the signDisplay option to include the plus sign for positive numbers, for example to display an offset from some value. In addition, it always displays a minimum of 1 digit after the decimal point, and allows up to 2 fraction digits. If the user enters more than 2 fraction digits, the result will be rounded.

<MyNumberField
  label="Adjust exposure"
  defaultValue={0}
  formatOptions={{
    signDisplay: 'exceptZero',
    minimumFractionDigits: 1,
    maximumFractionDigits: 2
  }} />

<MyNumberField
  label="Adjust exposure"
  defaultValue={0}
  formatOptions={{
    signDisplay: 'exceptZero',
    minimumFractionDigits: 1,
    maximumFractionDigits: 2
  }} />

<MyNumberField
  label="Adjust exposure"
  defaultValue={0}
  formatOptions={{
    signDisplay:
      'exceptZero',
    minimumFractionDigits:
      1,
    maximumFractionDigits:
      2
  }}
/>

Percentages#

The style: 'percent' option can be passed to the formatOptions prop to treat the value as a percentage. In this mode, the value is multiplied by 100 before it is displayed, i.e. 0.45 is displayed as 45%. The reverse is also true: when the user enters a value, the onChange event will be triggered with the entered value divided by 100. When the percent option is enabled, the default step automatically changes to 0.01 such that incrementing and decrementing occurs by 1%. This can be overridden with the step prop. See below for details.

<MyNumberField
  label="Sales tax"
  defaultValue={0.05}
  formatOptions={{
    style: 'percent'
  }} />

<MyNumberField
  label="Sales tax"
  defaultValue={0.05}
  formatOptions={{
    style: 'percent'
  }} />

<MyNumberField
  label="Sales tax"
  defaultValue={0.05}
  formatOptions={{
    style: 'percent'
  }} />

Currency values#

The style: 'currency' option can be passed to the formatOptions prop to treat the value as a currency value. The currency option must also be passed to set the currency code (e.g. USD) to use. In addition, the currencyDisplay option can be used to choose whether to display the currency symbol, currency code, or currency name. Finally, the currencySign option can be set to accounting to use accounting notation for negative numbers, which uses parentheses rather than a minus sign in some locales.

If you need to allow the user to change the currency, you should include a separate dropdown next to the number field. The number field itself will not determine the currency from the user input.

<MyNumberField
  label="Transaction amount"
  defaultValue={45}
  formatOptions={{
    style: 'currency',
    currency: 'EUR',
    currencyDisplay: 'code',
    currencySign: 'accounting'
  }} />

<MyNumberField
  label="Transaction amount"
  defaultValue={45}
  formatOptions={{
    style: 'currency',
    currency: 'EUR',
    currencyDisplay: 'code',
    currencySign: 'accounting'
  }} />

<MyNumberField
  label="Transaction amount"
  defaultValue={45}
  formatOptions={{
    style: 'currency',
    currency: 'EUR',
    currencyDisplay:
      'code',
    currencySign:
      'accounting'
  }}
/>

Units#

The style: 'unit' option can be passed to the formatOptions prop to format the value with a unit of measurement. The unit option must also be passed to set which unit to use (e.g. inch). In addition, the unitDisplay option can be used to choose whether to display the unit in long, short, or narrow format.

If you need to allow the user to change the unit, you should include a separate dropdown next to the number field. The number field itself will not determine the unit from the user input.

Note: the unit style is not currently supported in Safari. A polyfill may be necessary.

<MyNumberField
  label="Package width"
  defaultValue={4}
  formatOptions={{
    style: 'unit',
    unit: 'inch',
    unitDisplay: 'long'
  }} />

<MyNumberField
  label="Package width"
  defaultValue={4}
  formatOptions={{
    style: 'unit',
    unit: 'inch',
    unitDisplay: 'long'
  }} />

<MyNumberField
  label="Package width"
  defaultValue={4}
  formatOptions={{
    style: 'unit',
    unit: 'inch',
    unitDisplay: 'long'
  }} />

Validation#

Minimum and maximum values#

The minValue and maxValue props can be used to limit the entered value to a specific range. The value will be clamped when the user blurs the input field. In addition, the increment and decrement buttons will be disabled when the value is within one step value from the bounds (see below for info about steps). Ranges can be open ended by only providing either minValue or maxValue rather than both.

If a valid range is known ahead of time, it is a good idea to provide it to NumberField so it can optimize the experience. For example, when the minimum value is greater than or equal to zero, it is possible to use a numeric keyboard on iOS rather than a full text keyboard (necessary to enter a minus sign).

<MyNumberField
  label="Enter your age"
  minValue={0} />

<MyNumberField
  label="Enter your age"
  minValue={0} />

<MyNumberField
  label="Enter your age"
  minValue={0} />

Step values#

The step prop can be used to snap the value to certain increments. If there is a minValue defined, the steps are calculated starting from the minimum. For example, if minValue={2}, and step={3}, the valid step values would be 2, 5, 8, 11, etc. If no minValue is defined, the steps are calculated starting from zero and extending in both directions. In other words, such that the values are evenly divisible by the step. If no step is defined, any decimal value may be typed, but incrementing and decrementing snaps the value to an integer.

If the user types a value that is between two steps and blurs the input, the value will be snapped to the nearest step. When incrementing or decrementing, the value is snapped to the nearest step that is higher or lower, respectively. When incrementing or decrementing from an empty field, the value starts at the minValue or maxValue, respectively, if defined. Otherwise, the value starts from 0.

<MyNumberField
  label="Step"
  step={10} />
<MyNumberField
  label="Step + minValue"
  minValue={2}
  step={3} />
<MyNumberField
  label="Step + minValue + maxValue"
  minValue={2}
  maxValue={21}
  step={3} />

<MyNumberField
  label="Step"
  step={10} />
<MyNumberField
  label="Step + minValue"
  minValue={2}
  step={3} />
<MyNumberField
  label="Step + minValue + maxValue"
  minValue={2}
  maxValue={21}
  step={3} />

<MyNumberField
  label="Step"
  step={10}
/>
<MyNumberField
  label="Step + minValue"
  minValue={2}
  step={3}
/>
<MyNumberField
  label="Step + minValue + maxValue"
  minValue={2}
  maxValue={21}
  step={3}
/>

Validation errors#

NumberField supports the isRequired prop to ensure the user enters a value, as well as custom validation functions, realtime validation, and server-side validation. It can also be integrated with other form libraries. See the Forms guide to learn more.

To display validation errors, add a <FieldError> element as a child of the NumberField. This allows you to render error messages from all of the above sources with consistent custom styles.

import {Form, FieldError} from 'react-aria-components';

<Form>
  <NumberField name="width" isRequired>    <Label>Width</Label>
    <Group>
       <Button slot="decrement">-</Button>
       <Input />
       <Button slot="increment">+</Button>
     </Group>
    <FieldError />  </NumberField>
  <Button type="submit">Submit</Button>
</Form>

import {Form, FieldError} from 'react-aria-components';

<Form>
  <NumberField name="width" isRequired>    <Label>Width</Label>
    <Group>
       <Button slot="decrement">-</Button>
       <Input />
       <Button slot="increment">+</Button>
     </Group>
    <FieldError />  </NumberField>
  <Button type="submit">Submit</Button>
</Form>

import {
  FieldError,
  Form
} from 'react-aria-components';

<Form>
  <NumberField
    name="width"
    isRequired
  >    <Label>
      Width
    </Label>
    <Group>
      <Button slot="decrement">
        -
      </Button>
      <Input />
      <Button slot="increment">
        +
      </Button>
    </Group>
    <FieldError />  </NumberField>
  <Button type="submit">
    Submit
  </Button>
</Form>

Read only#

The isReadOnly prop makes the NumberField's value immutable. Unlike isDisabled, the NumberField remains focusable and the contents can still be copied. See the MDN docs for more information.

<MyNumberField label="Read only" isReadOnly value={32} />

<MyNumberField label="Read only" isReadOnly value={32} />

<MyNumberField
  label="Read only"
  isReadOnly
  value={32}
/>

Styling#

React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-NumberField {
  /* ... */
}

.react-aria-NumberField {
  /* ... */
}

.react-aria-NumberField {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<NumberField className="my-number-field">
  {/* ... */}
</NumberField>

<NumberField className="my-number-field">
  {/* ... */}
</NumberField>

<NumberField className="my-number-field">
  {/* ... */}
</NumberField>

In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:

.react-aria-Button[data-pressed] {
  /* ... */
}

.react-aria-Button[data-pressed] {
  /* ... */
}

.react-aria-Button[data-pressed] {
  /* ... */
}

The className and style props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.

<Button
  className={({ isPressed }) => isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>

<Button
  className={({ isPressed }) =>
    isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>

<Button
  className={(
    { isPressed }
  ) =>
    isPressed
      ? 'bg-gray-700'
      : 'bg-gray-600'}
/>

The states, selectors, and render props for each component used in a NumberField are documented below.

NumberField#

A NumberField can be targeted with the .react-aria-NumberField CSS selector, or by overriding with a custom className. It supports the following states:

Name	CSS Selector	Description
`isDisabled`	`[data-disabled]`	Whether the number field is disabled.
`isInvalid`	`[data-invalid]`	Whether the number field is invalid.
`state`	`—`	State of the number field.

Label#

A Label can be targeted with the .react-aria-Label CSS selector, or by overriding with a custom className.

Group#

A Group can be targeted with the .react-aria-Group selector, or by overriding with a custom className. It supports the following states:

Name	CSS Selector	Description
`isHovered`	`[data-hovered]`	Whether the group is currently hovered with a mouse.
`isFocusWithin`	`[data-focus-within]`	Whether an element within the group is focused, either via a mouse or keyboard.
`isFocusVisible`	`[data-focus-visible]`	Whether an element within the group is keyboard focused.
`isDisabled`	`[data-disabled]`	Whether the group is disabled.
`isInvalid`	`[data-invalid]`	Whether the group is invalid.

Input#

An Input can be targeted with the .react-aria-Input CSS selector, or by overriding with a custom className. It supports the following states:

Name	CSS Selector	Description
`isHovered`	`[data-hovered]`	Whether the input is currently hovered with a mouse.
`isFocused`	`[data-focused]`	Whether the input is focused, either via a mouse or keyboard.
`isFocusVisible`	`[data-focus-visible]`	Whether the input is keyboard focused.
`isDisabled`	`[data-disabled]`	Whether the input is disabled.
`isInvalid`	`[data-invalid]`	Whether the input is invalid.

Button#

A Button can be targeted with the .react-aria-Button CSS selector, or by overriding with a custom className. Within a NumberField, there are two slots, which can be targeted with the [slot=increment] and [slot=decrement] CSS selectors. Buttons support the following states:

Name	CSS Selector	Description
`isHovered`	`[data-hovered]`	Whether the button is currently hovered with a mouse.
`isPressed`	`[data-pressed]`	Whether the button is currently in a pressed state.
`isFocused`	`[data-focused]`	Whether the button is focused, either via a mouse or keyboard.

`isPending`	`[data-pending]`	Whether the button is currently in a pending state.

Text#

The help text elements within a NumberField can be targeted with the [slot=description] and [slot=errorMessage] CSS selectors, or by adding a custom className.

FieldError#

A FieldError can be targeted with the .react-aria-FieldError CSS selector, or by overriding with a custom className. It supports the following render props:

Name	Description
`isInvalid`	Whether the input value is invalid.
`validationErrors`	The current error messages for the input if it is invalid, otherwise an empty array.
`validationDetails`	The native validation details for the input.

Advanced customization#

Composition#

If you need to customize one of the components within a NumberField, such as Label or Input, in many cases you can create a wrapper component. This lets you customize the props passed to the component.

function MyInput(props) {
  return <Input {...props} className="my-input" />
}

function MyInput(props) {
  return <Input {...props} className="my-input" />
}

function MyInput(props) {
  return (
    <Input
      {...props}
      className="my-input"
    />
  );
}

Contexts#

All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).

Component	Context	Props	Ref
`NumberField`	`NumberFieldContext`	`NumberFieldProps`	`HTMLDivElement`

This example shows a FieldGroup component that renders a group of number fields with a title. The entire group can be marked as read only via the isReadOnly prop, which is passed to all child number fields via the NumberFieldContext provider.

import {NumberFieldContext} from 'react-aria-components';

interface FieldGroupProps {
  title?: string,
  children?: React.ReactNode,
  isReadOnly?: boolean
}

function FieldGroup({title, children, isReadOnly}: FieldGroupProps) {
  return (
    <fieldset>
      <legend>{title}</legend>
      <NumberFieldContext.Provider value={{isReadOnly}}>        {children}
      </NumberFieldContext.Provider>
    </fieldset>
  );
}

<FieldGroup title="Dimensions" isReadOnly>
  <MyNumberField label="Width" defaultValue={1024} />
  <MyNumberField label="Height" defaultValue={768} />
</FieldGroup>

import {NumberFieldContext} from 'react-aria-components';

interface FieldGroupProps {
  title?: string;
  children?: React.ReactNode;
  isReadOnly?: boolean;
}

function FieldGroup(
  { title, children, isReadOnly }: FieldGroupProps
) {
  return (
    <fieldset>
      <legend>{title}</legend>
      <NumberFieldContext.Provider value={{ isReadOnly }}>        {children}
      </NumberFieldContext.Provider>
    </fieldset>
  );
}

<FieldGroup title="Dimensions" isReadOnly>
  <MyNumberField label="Width" defaultValue={1024} />
  <MyNumberField label="Height" defaultValue={768} />
</FieldGroup>

import {NumberFieldContext} from 'react-aria-components';

interface FieldGroupProps {
  title?: string;
  children?:
    React.ReactNode;
  isReadOnly?: boolean;
}

function FieldGroup(
  {
    title,
    children,
    isReadOnly
  }: FieldGroupProps
) {
  return (
    <fieldset>
      <legend>
        {title}
      </legend>
      <NumberFieldContext.Provider
        value={{
          isReadOnly
        }}
      >        {children}
      </NumberFieldContext.Provider>
    </fieldset>
  );
}

<FieldGroup
  title="Dimensions"
  isReadOnly
>
  <MyNumberField
    label="Width"
    defaultValue={1024}
  />
  <MyNumberField
    label="Height"
    defaultValue={768}
  />
</FieldGroup>

}

fieldset {
  padding: 1.5em;
  width: fit-content;
}

fieldset {
  padding: 1.5em;
  width: fit-content;
}

Custom children#

NumberField passes props to its child components, such as the label and input, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.

Component	Context	Props	Ref
`Label`	`LabelContext`	`LabelProps`	`HTMLLabelElement`
`Group`	`GroupContext`	`GroupProps`	`HTMLDivElement`
`Input`	`InputContext`	`InputProps`	`HTMLInputElement`
`Button`	`ButtonContext`	`ButtonProps`	`HTMLButtonElement`
`Text`	`TextContext`	`TextProps`	`HTMLElement`

This example consumes from LabelContext in an existing styled label component to make it compatible with React Aria Components. The useContextProps hook merges the local props and ref with the ones provided via context by NumberField.

import type {LabelProps} from 'react-aria-components';
import {LabelContext, useContextProps} from 'react-aria-components';

const MyCustomLabel = React.forwardRef(
  (props: LabelProps, ref: React.ForwardedRef<HTMLLabelElement>) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(props, ref, LabelContext);
    // ... your existing Label component
    return <label {...props} ref={ref} />;
  }
);

import type {LabelProps} from 'react-aria-components';
import {
  LabelContext,
  useContextProps
} from 'react-aria-components';

const MyCustomLabel = React.forwardRef(
  (
    props: LabelProps,
    ref: React.ForwardedRef<HTMLLabelElement>
  ) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(
      props,
      ref,
      LabelContext
    );
    // ... your existing Label component
    return <label {...props} ref={ref} />;
  }
);

import type {LabelProps} from 'react-aria-components';
import {
  LabelContext,
  useContextProps
} from 'react-aria-components';

const MyCustomLabel =
  React.forwardRef(
    (
      props: LabelProps,
      ref:
        React.ForwardedRef<
          HTMLLabelElement
        >
    ) => {
      // Merge the local props and ref with the ones provided via context.
      [props, ref] =
        useContextProps(
          props,
          ref,
          LabelContext
        );
      // ... your existing Label component
      return (
        <label
          {...props}
          ref={ref}
        />
      );
    }
  );

Now you can use MyCustomLabel within a NumberField, in place of the builtin React Aria Components Label.

<NumberField>
  <MyCustomLabel>Value</MyCustomLabel>  <Group>
    <Button slot="decrement">-</Button>
    <Input />
    <Button slot="increment">+</Button>
  </Group>
</NumberField>

<NumberField>
  <MyCustomLabel>Value</MyCustomLabel>  <Group>
    <Button slot="decrement">-</Button>
    <Input />
    <Button slot="increment">+</Button>
  </Group>
</NumberField>

<NumberField>
  <MyCustomLabel>
    Value
  </MyCustomLabel>  <Group>
    <Button slot="decrement">
      -
    </Button>
    <Input />
    <Button slot="increment">
      +
    </Button>
  </Group>
</NumberField>

State#

NumberField provides a NumberFieldState object to its children via NumberFieldStateContext. This can be used to access and manipulate the NumberField's state.

Hooks#

If you need to customize things even further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. See useNumberField for more details.

Methods

Method	Description
`validate( (value: string )): boolean`	Validates a user input string according to the current locale and format options. Values can be partially entered, and may be valid even if they cannot currently be parsed to a number. Can be used to implement validation as a user types.
`setInputValue( (val: string )): void`	Sets the current text value of the input.
`setNumberValue( (val: number )): void`	Sets the number value.
`commit(): void`	Commits the current input value. The value is parsed to a number, clamped according to the minimum and maximum values of the field, and snapped to the nearest step value. This will fire the `onChange` prop with the new value, and if uncontrolled, update the `numberValue`. Typically this is called when the field is blurred.
`increment(): void`	Increments the current input value to the next step boundary, and fires `onChange`.
`decrement(): void`	Decrements the current input value to the next step boundary, and fires `onChange`.
`incrementToMax(): void`	Sets the current value to the `maxValue` if any, and fires `onChange`.
`decrementToMin(): void`	Sets the current value to the `minValue` if any, and fires `onChange`.
`updateValidation( (result: ValidationResult )): void`	Updates the current validation result. Not displayed to the user until `commitValidation` is called.
`resetValidation(): void`	Resets the displayed validation state to valid when the user resets the form.
`commitValidation(): void`	Commits the realtime validation so it is displayed to the user.
