小时

Code

import { InputNumber } from '@fibrous/semi-ui-solid';

export default function InputNumberDemo() {
    return (
        <div style={{ width: '280px' }}>
            <span id="inputnumber-basic-more-default-value">设置了默认值 defaultValue=1 </span>
            <InputNumber aria-labelledby="inputnumber-basic-more-default-value" defaultValue={1} />
            <br />
            <br />

            <span id="inputnumber-basic-more-disabled">禁用 disabled=true</span>
            <InputNumber aria-labelledby="inputnumber-basic-more-disabled" defaultValue={2} disabled />
            <br />
            <br />

            <span id="inputnumber-basic-more-precision">设置了小数位数 precision=2 </span>
            <InputNumber aria-labelledby="inputnumber-basic-more-precision" precision={2} defaultValue={1.234} />
            <br />
            <br />

            <span id="inputnumber-basic-more-inner-buttons">设置了 innerButtons=true </span>
            <InputNumber aria-labelledby="inputnumber-basic-more-inner-buttons" innerButtons suffix="小时" defaultValue={1} style={{ width: '190px' }} />
            <br />
        </div>
    );
}

Inner Buttons

With innerButtons, you can hide the buttons on the right into the interior, which will only be displayed when hover occurs

Code

import { InputNumber } from '@fibrous/semi-ui-solid';

export default function InputNumberDemo() {
    return <InputNumber aria-label="Number with inner buttons" innerButtons style={{ width: '190px' }} />;
}

The innerButtons buttons temporarily replace the content of the suffix prop while hovered or focused, and the original content comes back afterwards.

Set hideButtons to true to hide the buttons completely

Code

import { InputNumber } from '@fibrous/semi-ui-solid';

export default function InputNumberDemo() {
    return <InputNumber aria-label="Number without buttons" hideButtons style={{ width: '190px' }} />;
}

Size

默认尺寸 size=default

大尺寸 size=large

小尺寸 size=small

Code

import { InputNumber } from '@fibrous/semi-ui-solid';

export default function InputNumberDemo() {
    return (
        <div style={{ width: '180px' }}>
            <span id="inputnumber-size-default">默认尺寸 size=default</span>
            <InputNumber aria-labelledby="inputnumber-size-default" />
            <br />
            <br />

            <span id="inputnumber-size-large">大尺寸 size=large</span>
            <InputNumber aria-labelledby="inputnumber-size-large" size="large" />
            <br />
            <br />

            <span id="inputnumber-size-small">小尺寸 size=small</span>
            <InputNumber aria-labelledby="inputnumber-size-small" size="small" />
            <br />
        </div>
    );
}

Custom Display Format and Resolution

A pair of methods for formatter and parser, which generally need to be set at the same time, otherwise the value cannot be resolved correctly.

人民币

自定义串

Code

import { InputNumber } from '@fibrous/semi-ui-solid';

const log = (v: number | string) => {
    console.log(`Changed to: [${typeof v}] ${v}`);
};

export default function InputNumberDemo() {
    return (
        <div style={{ width: '180px' }}>
            <span id="inputnumber-formatter-rmb">人民币</span>
            <InputNumber aria-labelledby="inputnumber-formatter-rmb" onChange={log} defaultValue={1000} min={0} formatter={(value) => `￥ ${value}`.replace(/\B(?=(\d{3})+(?!\d))/g, ',')} parser={(value) => value.replace(/￥\s?|(,*)/g, '')} />
            <br />
            <br />

            <span id="inputnumber-formatter-custom">自定义串</span>
            <InputNumber aria-labelledby="inputnumber-formatter-custom" onChange={log} defaultValue={1111} formatter={(value) => String(value).split('').join('-')} parser={(value) => value.replace(/-/g, '')} />
            <br />
        </div>
    );
}

Can Only Enter Numbers

With formatter and onNumberChange (the numberChange event in Vue), a pure digital input box can be implemented.

Code

import { InputNumber } from '@fibrous/semi-ui-solid';

export default function InputNumberDemo() {
    return <InputNumber aria-label="Integer" formatter={(value) => `${value}`.replace(/\D/g, '')} onNumberChange={(number) => console.log(number)} min={0} max={Number.MAX_SAFE_INTEGER} />;
}

Currency Display

In internationalization mode, enable currency={true} (just currency in Vue) and the component will automatically display the corresponding currency type according to localeCode. (Note that the component key value needs to be updated after switching the language type)

Code

import { createSignal, For } from 'solid-js';
import type { Locale } from '@fibrous/semi-foundation/locale/interface';

            return;
        }
        setLocale(language[code]);
        setLocaleCode(code);
    };

    return (

            </LocaleProvider>
        </>
    );
}

You can also specify the currency to be displayed by manually passing localeCode and currency.

API Reference

Props

Property	Description	Type	Default
addonAfter	Trailing addon, shown outside the input on the right.	`JSX.Element`	-
addonBefore	Leading addon, shown outside the input on the left.	`JSX.Element`	-
borderless	Borderless mode.	`boolean`	-
clearIcon	Icon of the clear button, as an element. Takes effect only when `showClear` is `true`.	`JSX.Element`	-
composition	Whether to enable composition mode. When enabled, `onChange` is not called during IME composition and is called once after it ends.	`boolean`	-
currency	Currency, such as CNY, EUR or USD. When `true`, uses `defaultCurrency`, or the currency of the locale pack when that is not set.	`string \| boolean`	-
currencyDisplay	How the currency is shown: `symbol`, `code` or `name`.	`'code' \| 'symbol' \| 'name'`	-
defaultCurrency	Currency used when `currency` is `true`. Priority: own prop, global default, locale pack.	`string`	-
defaultValue	Initial value when uncontrolled.	`number \| string`	-
disabled	Whether disabled. Falls back to the value of the enclosing `InputGroup` when not set.	`boolean`	-
formatter	Format of the displayed value, usually set together with `parser`.	`Type`	-
getValueLength	Function that measures the text length. When set, it enforces `maxLength` and `minLength` instead of the native `maxlength` attribute.	`Type`	-
hideButtons	Hides the step buttons; with `innerButtons` also `true`, no built-in button is shown either.	`boolean`	-
hideSuffix	Hides the suffix while the clear button is shown; by default the two sit side by side.	`boolean`	-
innerButtons	Puts the step buttons inside the input, shown on hover or focus and temporarily replacing `suffix`.	`boolean`	`false`
inputRef	Callback ref for the native `input` element, which receives the `HTMLInputElement`; use it for native methods such as `select()`.	`Type`	-
inputStyle	Style of the native `input`, as an object (kebab-case keys) or a string.	`JSX.CSSProperties \| string`	-
insetLabel	Inset label, shown inside the input.	`JSX.Element`	-
insetLabelId	The id of the inset label.	`string`	-
keepFocus	Keeps the input focused when a step button is clicked.	`boolean`	`false`
localeCode	Locale code used for formatting in currency mode, such as zh-CN, en-US or de-DE. Priority: own prop, global default, locale pack of LocaleProvider or ConfigProvider.	`string`	-
max	Maximum value.	`number`	`Infinity`
maximumFractionDigits	Maximum number of fraction digits shown, passed to `Intl.NumberFormat`.	`number`	-
maxLength	Maximum length of the input text.	`number`	-
min	Minimum value.	`number`	`-Infinity`
minimumFractionDigits	Minimum number of fraction digits shown, passed to `Intl.NumberFormat`.	`number`	-
minLength	Minimum length of the input text.	`number`	-
mode	Input mode, `password`, which shows a button to toggle visibility.	`InputMode`	-
onBlur	Called when focus leaves the input; the event is the `focusout` of the wrapper.	`Type`	-
onChange	Called when the value changes. `e` is the typing, the `pointerdown` of a step button, the arrow or Home/End keydown, or the blur that caused it. Mounting and `value` changes do not call it; an out-of-range value is shown as given and is corrected and reported only after a user action.	`Type`	-
onClear	Called when the clear button is clicked.	`Type`	-
onDownClick	Called when the decrease button is clicked, with the stepped value and the `pointerdown` event. While held, it is called on every step with the event that began the press.	`Type`	-
onEnterPress	Called when the Enter key is pressed.	`Type`	-
onFocus	Called when focus enters the input; the event is the `focusin` of the wrapper.	`Type`	-
onKeyDown	Called when a key is pressed in the input; the event is its `keydown`.	`Type`	-
onlyBorder	Internal prop giving the border width of the wrapper in pixels, set by other components; callers normally do not pass it.	`number`	-
onNumberChange	Called when the number changes; the first argument is the number, and the second is as in `onChange`.	`Type`	-
onUpClick	Called when the increase button is clicked, with the stepped value and the `pointerdown` event. While held, it is called on every step with the event that began the press.	`Type`	-

pressInterval	Interval in milliseconds between repeats while a step button is held.	`number`	`250`
pressTimeout	Delay in milliseconds before repeating starts while a step button is held.	`number`	`250`
preventScroll	Whether focusing stops the browser from scrolling the document to the input; applies to focusing inside the component.	`boolean`	-
readonly	Whether read-only. Locks typing and hides the clear button; the native `readOnly` locks typing only.	`boolean`	-
ref	Ref of the root element (`.semi-input-number`), typed `HTMLDivElement`. `focus()` and `blur()` on the root act on the input.	`Type`	-
scientificNotation	Shows scientific notation when blurred and the full number when focused. Pass `{ threshold }` to configure the threshold, 15 significant digits by default. Not supported in currency mode.	`boolean \| ScientificNotationConfig`	-
shiftStep	Step of each change while Shift is held; may be a decimal.	`number`	`10`
showClear	Whether to show the clear button.	`boolean`	-
showClearIgnoreDisabled	Internal prop set by DatePicker; callers normally do not pass it.	`boolean`	-
showCurrencySymbol	Whether to show the currency symbol, code or name; only in currency mode.	`boolean`	`true`
size	Input size: `default`, `small` or `large`. The `size` of the enclosing `InputGroup` takes precedence when it is set.	`InputSize`	-
step	Step of each change; may be a decimal.	`number`	`1`
suffix	Suffix content, shown inside the input on the right.	`JSX.Element`	-
type	The `type` attribute of the native `input`, `text` by default.	`string`	-
validateStatus	Validation status: `default`, `error`, `warning` or `success`.	`ValidateStatus`	-
value	Current value; passing it makes the component controlled, so update it in `onChange`. An explicit `undefined` is treated as uncontrolled.	`number \| string`	-

class, style and ref land on the outer .semi-input-number root element; the other native attributes and events (id, name, aria-*, data-*, onInput, onKeyUp and so on) land on the native input.

Methods

ref gets the root element (HTMLDivElement), not a handle. focus() and blur() on the root act on the input, and focus() without arguments follows the preventScroll prop. Native methods such as select() and setSelectionRange() are called on the input element that inputRef receives.

Accessibility

Guideline: https://www.w3.org/WAI/ARIA/apg/patterns/spinbutton/

ARIA

InputNumber has spinbutton role
spinbutton uses aria-valuenow for current value, aria-valuemax for acceptable maximum value, and aria-valuemin for acceptable minimum value
When InputNumber is used in Form, the value of the input box's aria-labelledby reference is Field label

Keyboard and Focus

InputNumber can get focus, keyboard users can use Tab and Shift + Tab to switch focus (Increase and decrease buttons are not focusable)
Keyboard users can press up key ⬆️ or down key ⬇️ and the input value will increase or decrease by step (default is 1)
Hold down Shift + Up ⬆️ or Down ⬇️ , the input value will increase or decrease by shiftStep (default is 10)
Home jumps to the value of min and End to max, when that bound is set; without it the key moves the caret as usual
When the value is already at a bound and a key leaves it unchanged, onChange is not called (the change event in Vue)

Design Tokens

These are the component's internal Sass variables and cannot be overridden. To customize styles, override the --semi-* CSS variables (see the Design Token page) or write unlayered CSS rules.
