- 资源: Mantine Core (https://jiguang132.com/zh/resources/mantine.md)
- 全部指南: https://jiguang132.com/zh/resources/mantine/docs.md

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

## 安装

```bash
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。

## 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.w` | Mantine 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。

```tsx
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

```tsx
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`:

```tsx
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](/core/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:

```tsx
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](/styles/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](/hooks/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:

```tsx
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:

```tsx
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。
