NumberField

Das NumberField erlaubt die Eingabe und schrittweise Anpassung von Zahlen.

Alter(optional)

import {
  Label,
  NumberField,
} from "@mittwald/flow-react-components";

<NumberField minValue={0} maxValue={100}>
  <Label>Alter</Label>
</NumberField>

Best Practices

Definiere Mindest- und Höchstwerte (minValue/maxValue) sinnvoll, wenn du Eingaben einschränken willst.
Formuliere das Label prägnant und leicht verständlich.
Formuliere Fehlermeldungen klar, hilfreich und lösungsorientiert.

Einheit

Über das Property formatOptions lassen sich Einheiten für das NumberField definieren (s. Intl.NumberFormat).

Speicherplatz(optional)

Validierung

Nutze für die Validierung React Hook Form. Alternativ stehen aber auch folgende Properties zur Verfügung:

isRequired für Pflichtfelder.
validate für eigene Validierungen.

Bei ungültiger Eingabe wird das NumberField invalidiert. Über <FieldError /> kann eine entsprechende Fehlermeldung ausgegeben werden.

Required

Alter

Invalid

Alter(optional)Ungültige Eingabe

Mit FieldDescription

Um wichtige Hinweise zum NumberField bereitzustellen, kann unterhalb eine <FieldDescription /> eingebaut werden.

Alter(optional)Du musst mindestens 18 Jahre alt sein

Disabled

Achte bei der Verwendung von Disabled darauf, dass aus dem Kontext klar wird, warum der User gerade nicht mit dem NumberField interagieren kann.

Alter(optional)

Kombiniere mit ...

Combine

Benutze die Combine-Component, um andere Components wie einen Button neben dem NumberField auszurichten.

Alter(optional)

ContextualHelp

Verwende ContextualHelp, um zusätzliche Informationen bereitzustellen, die über den Umfang der FieldDescription hinausgehen.

React Hook Form

Weitere Details zur Formularlogik und -validierung findest du in der Component Form (React Hook Form).

Properties

Property	Type	Default	Description
`id`	`string`	-	The element's unique identifier. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id).
`translate`	`"yes" \| "no"`	-
`className`	`ClassNameOrFunction<NumberFieldRenderProps>`	'react-aria-NumberField'	The CSS [className](https://developer.mozilla.org/en-US/docs/Web/API/Element/className) for the element. A function may be provided to compute the class based on component state.
`style`	`StyleOrFunction<TooltipRenderProps>`	-	The inline [style](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/style) for the element. A function may be provided to compute the style based on component state.
`render`	`DOMRenderFunction<"div", TooltipRenderProps>`	-	Overrides the default DOM element with a custom render function. This allows rendering existing components with built-in styles and behaviors such as router links, animation libraries, and pre-styled components. Requirements: - You must render the expected element type (e.g. if `<button>` is expected, you cannot render an `<a>`). - Only a single root DOM element can be rendered (no fragments). - You must pass through props and ref to the underlying DOM element, merging with your own prop as appropriate.
`dir`	`string`	-
`lang`	`string`	-
`hidden`	`boolean`	-
`inert`	`boolean`	-
`validationBehavior`	`"native" \| "aria"`	'native'	Whether to use native HTML form validation to prevent form submission when the value is missing or invalid, or mark the field as required or invalid via ARIA.
`minValue`	`number`	-	The smallest value allowed for the input.
`maxValue`	`number`	-	The largest value allowed for the input.
`isDisabled`	`boolean`	-	Whether the input is disabled.
`isReadOnly`	`boolean`	-	Whether the input can be selected but not changed by the user.
`isRequired`	`boolean`	-	Whether user input is required on the input before form submission.
`isInvalid`	`boolean`	-	Whether the input value is invalid.
`validate`	`((value: TimeValue) => true \| ValidationError)`	-	A function that returns an error message if a given value is invalid. Validation errors are displayed to the user when the form is submitted if `validationBehavior="native"`. For realtime validation, use the `isInvalid` prop instead.
`autoFocus`	`boolean`	-	Whether the element should receive focus on render.
`value`	`TimeValue`	-	The current value (controlled).
`defaultValue`	`TimeValue`	-	The default value (uncontrolled).
`name`	`string`	-	The name of the input element, used when submitting an HTML form. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefname).
`form`	`string`	-	The `<form>` element to associate the input with. The value of this attribute must be the id of a `<form>` in the same document. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input#form).
`slot`	`string`	-	A slot name for the component. Slots allow the component to receive props from a parent component. An explicit `null` value indicates that the local props completely override all props received from a parent.
`step`	`number`	-	The amount that the input value changes with each increment or decrement "tick".
`formatOptions`	`NumberFormatOptions`	-	Formatting options for the value displayed in the number field. This also affects what characters are allowed to be typed by the user.
`decrementAriaLabel`	`string`	-	A custom aria-label for the decrement button. If not provided, the localized string "Decrement" is used.
`incrementAriaLabel`	`string`	-	A custom aria-label for the increment button. If not provided, the localized string "Increment" is used.
`isWheelDisabled`	`boolean`	-	Enables or disables changing the value with scroll.
`commitBehavior`	`"validate" \| "snap"`	'snap'	Controls the behavior of the number field when the user blurs the field after editing. 'snap' will clamp the value to the min/max values, and snap to the nearest step value. 'validate' will not clamp the value, and will validate that the value is within the min/max range and on a valid step.
`children`	`ReactNode`	-
`wrapWith`	`ReactElement<unknown, string \| JSXElementConstructor<any>>`	-	A React element the component is wrapped with. The element is cloned and receives the component as its only child — useful to render the component inside a link, a tooltip trigger or any other wrapper without changing the surrounding markup.
`ref`	`Ref<HTMLSpanElement>`	-	Allows getting a ref to the component instance. Once the component unmounts, React will set `ref.current` to `null` (or call the ref with `null` if you passed a callback ref). @see React Docs
`key`	`Key`	-
