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

选择或展示评分。

## 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 |
| --- | --- |
| `Rating.readOnly` | 阻止编辑并保留只读交互。 |
| `Rating.defaultValue` | 非受控初始值，不是持续更新的受控值。 |

## 交互与状态检查

当前场景：默认、只读。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 readOnly = variant === "Read only";
return <M.Rating readOnly={readOnly} defaultValue={3} />;
}
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、只读

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 { Rating } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState(0);
  return <Rating value={value} onChange={setValue} />;
}
```

## Uncontrolled

`Rating` can be used with uncontrolled forms the same way as a native input element.
Set the `name` attribute to include rating value in `FormData` object on form submission.
To control the initial value in uncontrolled forms, use the `defaultValue` prop.

Example usage of uncontrolled `Rating` with `FormData`:

```tsx
import { Rating } from '@mantine/core';

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

## Read only



## Allow clear

Set `allowClear` prop to allow users to reset the rating to 0 by clicking the same rating value again.
This is useful when you want to give users the ability to undo their rating selection:



## Fractions



## Custom symbol



## Symbols for each item




## 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。


```ts
Rating(_props)
```



```ts
export type RatingStylesNames =
  | 'root'
  | 'starSymbol'
  | 'input'
  | 'label'
  | 'symbolBody'
  | 'symbolGroup';

export type RatingCssVariables = {
  root: '--rating-size' | '--rating-color';
};

export interface RatingProps
  extends BoxProps, StylesApiProps<RatingFactory>, ElementProps<'div', 'onChange'> {
  /** Uncontrolled component default value */
  defaultValue?: number;

  /** Controlled component value */
  value?: number;

  /** Called when value changes */
  onChange?: (value: number) => void;

  /** Icon displayed for unselected rating items. Can be a function that receives the rating value. */
  emptySymbol?: React.ReactNode | ((value: number) => React.ReactNode);

  /** Icon displayed for selected rating items. Can be a function that receives the rating value. */
  fullSymbol?: React.ReactNode | ((value: number) => React.ReactNode);

  /** Number of fractions each item can be divided into, default is 1 */
  fractions?: number;

  /** Controls component size @default 'sm' */
  size?: MantineSize | number | (string & {});

  /** Number of rating items (stars), default is 5 */
  count?: number;

  /** Called when rating item is hovered. Receives -1 when hover ends. */
  onHover?: (value: number) => void;

  /** Function to generate aria-label for each rating value. Receives the rating value as argument, default is (value) => String(value) */
  getSymbolLabel?: (index: number) => string;

  /** Name attribute for form submission. If not provided, a unique id will be generated. */
  name?: string;

  /** When true, rating cannot be changed by user interaction, default is false */
  readOnly?: boolean;

  /** When true, clicking the same rating value clears the rating to 0, default is false */
  allowClear?: boolean;

  /** When true, only the clicked rating item is highlighted, not all items up to the selected value, default is false */
  highlightSelectedOnly?: boolean;

  /** Key of theme.colors or any CSS color value, default is 'yellow' */
  color?: MantineColor;
}

export type RatingFactory = Factory<{
  props: RatingProps;
  ref: HTMLDivElement;
  stylesNames: RatingStylesNames;
  vars: RatingCssVariables;
}>;

export type Mod = Record<string, any> | string;

export type BoxMod = Mod | Mod[] | BoxMod[];

export interface BoxProps extends MantineStyleProps {
  /** Class added to the root element, if applicable */
  className?: string | undefined;

  /** Inline style added to root component element, can subscribe to theme defined on MantineProvider */
  style?: MantineStyleProp;

  /** CSS variables defined on root component element */
  __vars?: CssVarsProp;

  /** `size` property passed down the HTML element */
  __size?: string;

  /** Breakpoint above which the component is hidden with `display: none` */
  hiddenFrom?: MantineBreakpoint;

  /** Breakpoint below which the component is hidden with `display: none` */
  visibleFrom?: MantineBreakpoint;

  /** Determines whether component should be hidden in light color scheme with `display: none` */
  lightHidden?: boolean;

  /** Determines whether component should be hidden in dark color scheme with `display: none` */
  darkHidden?: boolean;

  /** Element modifiers transformed into `data-` attributes, for example, `{ 'data-size': 'xl' }`, falsy values are removed */
  mod?: BoxMod;
}

export type ElementProps<
  ElementType extends React.ElementType,
  PropsToOmit extends string = never,
> = Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>;

export interface CSSProperties extends React.CSSProperties {
  [key: string]: any;
}

type MantineStyle = CSSProperties | ((theme: MantineTheme) => CSSProperties);

export type MantineStyleProp = MantineStyle | MantineStyle[] | MantineStyleProp[] | undefined;

export type CssVariable = `--${string}`;

export type CssVariables<Variable extends string = CssVariable> = Partial<Record<Variable, string>>;

export type CssVars<Variable extends string = CssVariable> =
  | CssVariables<Variable>
  | ((theme: MantineTheme) => CssVariables<Variable>)
  | CssVars<Variable>[];

export type CssVarsProp<Variable extends string = CssVariable> =
  | CssVars<Variable>
  | CssVars<Variable>[];
```


### 原生与外部类型

以下外部类型仍由 React 或资源自身依赖定义，没有手工展开为虚构属性。实际可用类型以安装版本的 TypeScript 检查为准。


```ts
Factory<{
  props: RatingProps;
  ref: HTMLDivElement;
  stylesNames: RatingStylesNames;
  vars: RatingCssVariables;
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<RatingFactory>
React.ElementType
Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>
React.ComponentProps<ElementType>
ElementType
PropsToOmit
React.ReactNode
MantineSize
MantineColor
HTMLDivElement
```
