Slider · Mantine Core

滑块

Mantine Core 的独立组件，请不要替换为 JGuang UI/Base UI 的同名 API。

安装

npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1

入口引入 @mantine/core/styles.css，并在根组件使用 MantineProvider；通过 forceColorScheme 同步深浅色主题。

使用与验证

在左侧选择组件，在预览中操作它的状态；使用“查看代码”检查真实源码。安装后执行类型检查和构建，再验证键盘焦点、手机布局与深浅色主题。

来源

https://github.com/mantinedev/mantine/tree/f0e2bc6d28b0f0b8aaefb5b859937bf77f539df7 MIT 许可证；不包括付费内容。下方提供上游英文参考内容，中文使用指南已适配；上游详细参考暂保留英文。

版本与兼容性

固定的 Mantine Core 9.7.1 要求 React 和 React DOM 满足 ^19.2.0，并配套 @mantine/hooks@9.7.1。此条件来自实际 npm 包的 peerDependencies。React 18 或其他不兼容版本不能强行安装；先向项目负责人说明升级影响并确认方案，不使用 --force/--legacy-peer-deps 掩盖冲突。入口的原生 Provider 开启 theme.respectReducedMotion，并用 forceColorScheme 控制深浅色。

适用场景

通过指针或键盘编辑数值。

本地示例使用的原生参数

以下参数由本地、经过类型检查的 JSX 示例提取，按所属组件区分。不是全部属性清单；完整签名和继承关系见下方固定源码参考。

组件参数说明
Slider.value受控值，具体结构由原生类型定义。
Slider.onChange原生值或事件回调，保留实际函数签名。
Slider.wMantine 宽度样式参数。

交互与状态检查

当前场景：默认。切换支持的禁用、错误或只读场景后检查真实行为；无此原生状态的组件不会被强行添加统一属性。验证键盘焦点和退出方式，修改值后按原生回调签名连接业务状态。

业务接入边界

示例内容和状态仅保存在本地，不提供服务端持久化、授权或数据请求。静态展示组件不应被当作已完成的业务流程。

宿主配置

先安装固定版本 @mantine/core 和 @mantine/hooks，在入口引入 @mantine/core/styles.css，并使用 MantineProvider。示例的 theme 和 variant 是 JGuang 编写的宿主参数，不是所有原生组件都接受的统一 API；通过 forceColorScheme 同步应用主题。源码面板中的原生实现仅供阅读，使用 npm 导出，不要单独复制内部实现。此批只覆盖 Core，不包括日期、图表和表单扩展包。上游详细说明保留英文，不宣称全文中文化。

可运行用法

以下代码使用资源原生 API；不是把其他设计系统的同名组件替换进来。

import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {
const [value, setValue] = useState(35);
return <M.Slider value={value} onChange={setValue} w={300} />;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

可用状态与示例

默认

示例遵循 Mantine 原生 API。支持多状态的输入组件可将示例中的 variant 改为 Disabled、Invalid 或 Read only；这些只是示例标签，不是新增的组件属性。改造时保留组件要求的数据、受控值、store 和复合子组件结构。

Usage

Controlled

import { useState } from 'react';
import { Slider } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState(40);
  return <Slider value={value} onChange={setValue} />;
}

Uncontrolled

Slider can be used in uncontrolled forms the same way as a native input element. Set the name attribute to include the slider value in the FormData object on form submission. To set the initial value in uncontrolled mode, use the defaultValue prop.

Example usage of uncontrolled Slider with FormData:

import { Slider } from '@mantine/core';

function Demo() {
  return (
    <form
      onSubmit={(event) => {
        event.preventDefault();
        const formData = new FormData(event.currentTarget);
        console.log('Slider value:', formData.get('volume'));
      }}
    >
      <Slider name="volume" defaultValue={40} min={0} max={100} />
      <button type="submit">Submit</button>
    </form>
  );
}

Disabled

onChangeEnd

onChangeEnd callback is called when the user stops dragging the slider or when the value is changed with the keyboard. You can use it as a debounced callback to avoid too frequent updates.

Control label

To change label behavior and appearance, set the following props:

  • label – formatter function, accepts value as an argument, set null to disable label, defaults to f => f
  • labelAlwaysOn – if true, the label will always be displayed; by default the label is visible only when the user is dragging
  • labelTransitionProps – props passed down to the Transition component, can be used to customize label animation

Min, max and step

Domain

By default, the min and max props define both the visual range (track display) and the selectable range (possible values). The domain prop allows you to independently control the selectable range. This is useful when you want to display a wider track (for context) but restrict the actual selection to a subset.

In the example below, the track displays from 0 to 100 (min/max), but the thumb can only be dragged between 20 and 80 (domain):

Decimal values

To use Slider with decimal values, set min, max and step props:

Marks

Add any number of marks to the slider by setting the marks prop to an array of objects:

const marks = [
  { value: 20 }, // -> displays mark on slider track
  { value: 40, label: '40%' }, // -> adds mark label below slider track
];

Note that the mark value is relative to the slider value, not width:

Restrict selection to marks

Set the restrictToMarks prop to restrict the slider value to marks only. Note that in this case the step prop is ignored:

Thumb size

Thumb children

Scale

You can use the scale prop to represent the value on a different scale.

In the following demo, the value x represents the value 2^x. Increasing x by one increases the represented value by 2 to the power of x.

Start point

Use the startPointValue prop to change the origin of the filled bar. When set, the bar extends from the given value toward the current value – to the left for values below the start point and to the right for values above it. This prop is ignored when inverted is set.

Inverted

You can invert the track with the inverted prop:

Example of using Styles API to change Slider styles:

Vertical slider

Set orientation="vertical" to render the slider vertically. In vertical orientation, the minimum value is at the bottom and the maximum value is at the top.

Hidden marks

Hidden marks allow you to snap to specific values without displaying them visually on the track. This is useful when you want to create a "sticky" snapping behavior to certain values that you don't want to show to the user. Use this feature together with restrictToMarks prop:

Build custom slider

If the Slider component does not meet your requirements, you can build a custom slider with the use-move hook:

Accessibility

Slider component is accessible by default:

  • Thumbs are focusable
  • When the user uses the mouse to interact with the slider, focus is moved to the slider track; when the user presses arrows, focus is moved to the thumb
  • The value can be changed with arrows with step increment/decrement

To label the component for screen readers, add labels to thumbs:

import { Slider } from '@mantine/core';

function Demo() {
  return <Slider thumbLabel="Thumb aria-label" />;
}

When scale is used or the displayed value is formatted (for example as a currency or percentage), set thumbValueText to provide a human-readable value for screen readers. It is rendered as aria-valuetext on the thumb. When a function is provided, it receives the scaled value:

import { Slider } from '@mantine/core';

function Demo() {
  return (
    <Slider
      scale={(v) => v * 10}
      thumbValueText={(value) => `$${value}`}
    />
  );
}

Keyboard interactions

源码参数参考

以下实现签名和类型从本地固定版本源码生成。保留可选属性、原生继承类型、联合分支和 never 限制；不会将其他设计系统的 API 混入。forwardRef 实现中的 ref 属于 React 引用，不是新增业务属性。此区域是原始类型参考，不是上游说明的全文翻译。
