Verwende Buttons, um z. B. ...
- eine Aktion auszuführen oder ein Event zu starten, ohne die Seite zu verlassen.
- Formulare zu speichern oder zurückzusetzen.
- in einem Modal Aktionen auszuwählen.
import { Button } from "@mittwald/flow-react-components"; <Button onPress={() => { alert("Button gedrückt"); }} > Button </Button>
aria-label, wenn der
Kontext nicht klar ist, etwa bei einem reinen Icon-Button oder wenn der Text
allein nicht ausreicht.Verwende für Navigation bevorzugt Links und für Aktionen Buttons. Eine Ausnahme können hervorgehobene Call-to-Actions sein, bei denen ein Button-ähnliches Erscheinungsbild für eine Navigation sinnvoll ist.
Verwende die unterschiedlichen Varianten, um Buttons in einer Oberfläche eine visuelle Hierarchie zu geben:
Farben unterstützen die visuelle Hierarchie zusätzlich. Verwende:
Um auf farbigen Hintergründen ausreichend Kontrast zu erreichen, können Buttons auch in Light und Dark eingesetzt werden. Mehr zur richtigen Verwendung von Light und Dark findest du in den Foundations unter Color.
Medium ist die Standardgröße und wird für die meisten Buttons verwendet. Small kann genutzt werden, wenn weniger Platz vorhanden ist. Vermeide es, unterschiedliche Button-Größen direkt nebeneinander zu verwenden.
Disabled zeigt an, dass eine Aktion nicht ausgeführt werden kann. Achte darauf, dass aus dem Kontext klar wird, warum die Aktion nicht zur Verfügung steht.
Die States Pending, Succeeded und Failed geben dem User zusätzliches visuelles Feedback darüber, dass im Hintergrund eine Aktion läuft, erfolgreich abgeschlossen wurde oder fehlgeschlagen ist. Um diese States zu steuern, kann die Action-Komponente genutzt werden.
Der Content-Bereich eines Buttons kann entweder Text, ein Icon oder Text mit einem Icon am Ende enthalten. Achte in allen Fällen darauf, dass Text und Icon die Aktion eindeutig beschreiben.
Wenn ausschließlich ein Icon verwendet wird, sollte das aria-label den
Verwendungszweck beschreiben. Ein Tooltip kann zusätzlich verdeutlichen, wofür
die Aktion gedacht ist.
Der Default ist Text ohne Icon, das hält die Oberfläche ruhig. Ein Icon kommt nur dazu, wenn es etwas beiträgt, das der Text allein nicht abdeckt:
Wiederholt das Icon nur das Wort (etwa eine Diskette neben „Speichern"), bringt es nur Unruhe. Im Zweifel weglassen.
Benutze die Align-Component, um deinen Button neben Input-Feldern zu platzieren.
Benutze die ActionGroup-Component, um zusammengehörige Aktionen zu gruppieren und automatisch in eine konsistente Hierarchie (Haupt- und Nebenaktion) zu bringen.
Benutze die Action-Component, um die States eines Buttons zu steuern.
| Property | Type | Default | Description |
|---|---|---|---|
slot | string | - | Slot for button placement in action groups. |
color | "dark" | "light" | "dark-static" | "light-static" | "danger" | "primary" | "accent" | "secondary" | "primary" | The color of the button. |
variant | "solid" | "plain" | "soft" | "outline" | "solid" | The visual variant of the button. |
size | "s" | "m" | "m" | The size of the button. |
isPending | boolean | - | Whether the button is in a pending state. |
isSucceeded | boolean | - | Whether the button is in a succeeded state. |
isFailed | boolean | - | Whether the button is in a failed state. |
isReadOnly | boolean | - | Whether the button is in a read only state. |
className | ClassNameOrFunction<ButtonRenderProps> | 'react-aria-Button' | 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. |
id | string | - | The element's unique identifier. See [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id). |
isDisabled | boolean | - | Whether the button is disabled. |
autoFocus | boolean | - | Whether the element should receive focus on render. |
value | string | - | The value associated with the button's name when it's submitted with the form data. |
name | string | - | Submitted as a pair with the button's value as part of the form data. |
form | string | - | The `<form>` element to associate the button 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/button#form). |
excludeFromTabOrder | boolean | - | Whether to exclude the element from the sequential tab order. If true, the element will not be focusable via the keyboard by tabbing. This should be avoided except in rare scenarios where an alternative means of accessing the element or its functionality via the keyboard is available. |
type | "button" | "submit" | "reset" | 'button' | The behavior of the button when used in an HTML form. |
formAction | string | ((formData: FormData) => void | Promise<void>) | - | The URL that processes the information submitted by the button. Overrides the action attribute of the button's form owner. |
formEncType | string | - | Indicates how to encode the form data that is submitted. |
formMethod | string | - | Indicates the HTTP method used to submit the form. |
formNoValidate | boolean | - | Indicates that the form is not to be validated when it is submitted. |
formTarget | string | - | Overrides the target attribute of the button's form owner. |
preventFocusOnPress | boolean | - | Whether to prevent focus from moving to the button when pressing it. Caution, this can make the button inaccessible and should only be used when alternative keyboard interaction is provided, such as ComboBox's MenuTrigger or a NumberField's increment/decrement control. |
children | ReactNode | - | The children of the component. A function may be provided to alter the children 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. |
translate | "yes" | "no" | - | |
dir | string | - | |
lang | string | - | |
hidden | boolean | - | |
inert | boolean | - | |
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 | - |
| Property | Type | Default | Description |
|---|---|---|---|
onClick | ((e: MouseEvent<FocusableElement, MouseEvent>) => void) | - | **Not recommended – use `onPress` instead.** `onClick` is an alias for `onPress` provided for compatibility with other libraries. `onPress` provides additional event details for non-mouse interactions. |
onFocus | ((e: FocusEvent<Element, Element>) => void) | - | Handler that is called when the element receives focus. |
onBlur | ((e: FocusEvent<Element, Element>) => void) | - | Handler that is called when the element loses focus. |
onFocusChange | ((isFocused: boolean) => void) | - | Handler that is called when the element's focus status changes. |
onKeyDown | ((e: KeyboardEvent) => void) | - | Handler that is called when a key is pressed. |
onKeyUp | ((e: KeyboardEvent) => void) | - | Handler that is called when a key is released. |
onPress | ((e: PressEvent) => void) | - | Handler that is called when the press is released over the target. |
onPressStart | ((e: PressEvent) => void) | - | Handler that is called when a press interaction starts. |
onPressEnd | ((e: PressEvent) => void) | - | Handler that is called when a press interaction ends, either over the target or when the pointer leaves the target. |
onPressChange | ((isPressed: boolean) => void) | - | Handler that is called when the press state changes. |
onPressUp | ((e: PressEvent) => void) | - | Handler that is called when a press is released over the target, regardless of whether it started on the target or not. |
onHoverStart | ((e: HoverEvent) => void) | - | Handler that is called when a hover interaction starts. |
onHoverEnd | ((e: HoverEvent) => void) | - | Handler that is called when a hover interaction ends. |
