> Calendar 从 HeroUI v2 到 v3 的迁移指南。

- 页面: https://jiguang132.com/zh/systems/heroui/docs/migration/calendar
- 改编自: HeroUI 文档 (Apache-2.0) @ 60edd8ed751b1d2a270623fbb182bbcfa8baa9af

> 
  完整的 API 参考、样式指南与高级示例请参阅 [v3 Calendar 文档](/systems/heroui/docs/components/calendar)。本指南只关注从 HeroUI v2 的迁移。


## 结构变化

在 v2 中，`Calendar` 是一个完全通过 props 配置的单一组件：

```tsx
import { Calendar } from "@heroui/react";

export default function App() {
  return <Calendar aria-label="Date" />;
}
```

在 v3 中，Calendar 改用带显式子组件的复合组件模式：

```tsx
import { Calendar } from "@heroui/react";

export default function App() {
  return (
    <Calendar aria-label="Date">
      <Calendar.Header>
        <Calendar.Heading />
        <Calendar.NavButton slot="previous" />
        <Calendar.NavButton slot="next" />
      </Calendar.Header>
      <Calendar.Grid>
        <Calendar.GridHeader>
          {(day) => <Calendar.HeaderCell>{day}</Calendar.HeaderCell>}
        </Calendar.GridHeader>
        <Calendar.GridBody>
          {(date) => <Calendar.Cell date={date} />}
        </Calendar.GridBody>
      </Calendar.Grid>
    </Calendar>
  );
}
```

## 主要变化

### 1. 组件结构

**v2：** 单一 `Calendar` 组件，所有布局都在内部处理  
**v3：** 复合组件：`Calendar.Header`、`Calendar.Heading`、`Calendar.NavButton`、`Calendar.Grid`、`Calendar.GridHeader`、`Calendar.GridBody`、`Calendar.HeaderCell`、`Calendar.Cell`、`Calendar.CellIndicator`

### 2. 年份选择器

**v2：** 通过 `showMonthAndYearPickers` prop 提供内置月份 / 年份选择器  
**v3：** 使用专用复合组件：`Calendar.YearPickerTrigger`、`Calendar.YearPickerGrid`、`Calendar.YearPickerGridBody`、`Calendar.YearPickerCell`

### 3. Prop 变更

| v2 prop | v3 等效项 | 说明 |
| ------- | ----------- | ---- |
| `value` | `value` | 保持一致 |
| `defaultValue` | `defaultValue` | 保持一致 |
| `onChange` | `onChange` | 保持一致 |
| `focusedValue` | `focusedValue` | 保持一致 |
| `onFocusChange` | `onFocusChange` | 保持一致 |
| `minValue` | `minValue` | 保持一致 |
| `maxValue` | `maxValue` | 保持一致 |
| `isDateUnavailable` | `isDateUnavailable` | 保持一致 |
| `isDisabled` | `isDisabled` | 保持一致 |
| `isReadOnly` | `isReadOnly` | 保持一致 |
| `isInvalid` | `isInvalid` | 保持一致 |
| `visibleMonths` | `visibleDuration` | 改为 `{months: number}` 对象 |
| `showMonthAndYearPickers` | - | 使用 `Calendar.YearPickerTrigger` 和 `Calendar.YearPickerGrid` |
| `onHeaderExpandedChange` | `onYearPickerOpenChange` | 已重命名 |
| `color` | - | 已移除（请改用 Tailwind CSS） |
| `calendarWidth` | - | 已移除（请改用 `className` 或 Tailwind CSS） |
| `weekdayStyle` | - | 已移除 |
| `pageBehavior` | `pageBehavior` | 保持一致 |
| `firstDayOfWeek` | - | 改用 `I18nProvider` 的 locale |
| `hideDisabledDates` | - | 已移除 |
| `disableAnimation` | - | 已移除 |
| `topContent` | - | 将自定义内容作为 `Calendar` children 放在 `Calendar.Grid` 之前 |
| `bottomContent` | - | 将自定义内容作为 `Calendar` children 放在 `Calendar.Grid` 之后 |
| `classNames` | - | 在各个复合组件上使用 `className` |
| `errorMessage` | - | 已移除（请在外部处理校验） |

### 4. color prop 已移除

**v2：** `color` prop 支持 `default`、`primary`、`secondary`、`success`、`warning`、`danger`  
**v3：** 不再提供 `color` prop，请使用 Tailwind CSS 类设置单元格样式，或通过自定义 `calendar.css` 覆盖

        <button onClick={() => setValue(today(getLocalTimeZone()))}>
          Today
        </button>
      }
    />
    ```
  
  

#### v3


    ```tsx
    <Calendar aria-label="Date">
      <p>Select a date</p>
      <Calendar.Header>
        <Calendar.Heading />
        <Calendar.NavButton slot="previous" />
        <Calendar.NavButton slot="next" />
      </Calendar.Header>
      <Calendar.Grid>
        <Calendar.GridHeader>
          {(day) => <Calendar.HeaderCell>{day}</Calendar.HeaderCell>}
        </Calendar.GridHeader>
        <Calendar.GridBody>
          {(date) => <Calendar.Cell date={date} />}

    ```
  


### 单元格指示器


  

#### v2


    ```tsx
    {/* v2 did not have a built-in cell indicator API */}
    ```
  
  

#### v3


    ```tsx
    <Calendar.Grid>
      <Calendar.GridHeader>
        {(day) => <Calendar.HeaderCell>{day}</Calendar.HeaderCell>}
      </Calendar.GridHeader>
      <Calendar.GridBody>
        {(date) => (
          <Calendar.Cell date={date}>
            {({formattedDate}) => (
              <>
                {formattedDate}
                {hasEvent(date) && <Calendar.CellIndicator />}
              </>
            )}
          </Calendar.Cell>
        )}
      </Calendar.GridBody>
    </Calendar.Grid>
    ```
  


## 样式变化

### v2：`classNames` prop

```tsx
<Calendar
  classNames={{
    base: "custom-base",
    prevButton: "custom-prev",
    nextButton: "custom-next",
    title: "custom-title",
    cell: "custom-cell",
    cellButton: "custom-cell-button",
  }}
/>
```

### v3：直接使用 `className` prop

```tsx
<Calendar className="custom-base">
  <Calendar.Header>
    <Calendar.Heading className="custom-title" />
    <Calendar.NavButton slot="previous" className="custom-prev" />
    <Calendar.NavButton slot="next" className="custom-next" />
  </Calendar.Header>
  <Calendar.Grid>
    <Calendar.GridHeader>
      {(day) => <Calendar.HeaderCell>{day}</Calendar.HeaderCell>}
    </Calendar.GridHeader>
    <Calendar.GridBody>
      {(date) => <Calendar.Cell date={date} className="custom-cell" />}
    </Calendar.GridBody>
  </Calendar.Grid>
</Calendar>
```

## 组件结构

v3 Calendar 遵循以下结构：

```
Calendar (Root)
  ├── [Custom top content]
  ├── Calendar.Header
  │   ├── Calendar.Heading (or Calendar.YearPickerTrigger)
  │   ├── Calendar.NavButton slot="previous"
  │   └── Calendar.NavButton slot="next"
  ├── Calendar.Grid (one per visible month)
  │   ├── Calendar.GridHeader
  │   │   └── Calendar.HeaderCell (render prop)
  │   └── Calendar.GridBody
  │       └── Calendar.Cell (render prop)
  │           └── Calendar.CellIndicator (optional)
  ├── Calendar.YearPickerGrid (optional)
  │   └── Calendar.YearPickerGridBody
  │       └── Calendar.YearPickerCell
  └── [Custom bottom content]
```

## 总结

1. **组件结构**：单一组件 → 带显式布局控制的复合组件
2. **年份选择器**：`showMonthAndYearPickers` prop → 专用的 `Calendar.YearPickerTrigger` 和 `Calendar.YearPickerGrid` 组件
3. **多个月份**：`visibleMonths={n}` → `visibleDuration={{months: n}}`，并使用多个带 `offset` 的 `Calendar.Grid` 组件
4. **color 已移除**：请改用 Tailwind CSS 类
5. **顶部 / 底部内容**：prop 已移除 → 直接将内容作为 children 放在 `Calendar` 内
6. **单元格自定义**：新增 `Calendar.CellIndicator`，且 `Calendar.Cell` 支持渲染 prop
7. **样式**：`classNames` prop → 各个复合组件上的 `className`
8. **已移除 prop**：`calendarWidth`、`weekdayStyle`、`hideDisabledDates`、`disableAnimation` —— 请使用 Tailwind CSS 或省略
