Adds aria-invalid support to slider handles. Global ariaInvalid accepts booleans, grammar and spelling; ariaInvalidForHandle can override individual handles. Missing array entries fall back to the global value while an explicit false remains false.

The new regression uses a two-handle range with global grammar and per-handle [false]. Before the fix the second handle had no aria-invalid; after the fix it receives grammar. README documents the fallback.

Validation: all 132 Jest tests and 5 snapshots pass; TypeScript, lint and compile pass. The suite still emits existing React act warnings. Native-browser and screen-reader checks were not run for this follow-up.

Summary by CodeRabbit

  • 新功能

    • Slider 支持通过 ariaInvalid 为所有句柄设置 aria-invalid 状态,也支持通过 ariaInvalidForHandle 分别配置各个句柄。
    • 逐句柄配置未提供某项时,将回退使用 ariaInvalid 的值。
    • 新增并公开 AriaInvalid 类型,支持布尔值以及 grammar、spelling 值。
  • 文档

    • 更新中英文 Slider API 文档,补充无障碍属性说明。

直接关联的开放议题为 #1097。SliderProps 新增 ariaInvalid?: AriaInvalid,并将该值传递到句柄。每个 role="slider" 句柄会设置 aria-invalid。实现也支持 #1097 要求的布尔值,并扩展支持 grammar、spelling。ariaInvalidForHandle 支持逐句柄配置。缺失的数组项回退到全局值,显式 false 保持为 false。测试覆盖单滑块、范围滑块和回退行为。

按 slider 角色查找句柄。

当前测试在句柄失去 role="slider" 时仍会通过。请用 getByRole('slider') 查找句柄,再检查 aria-invalid;这样测试也能验证属性位于可访问的滑块上。Based on learnings:React Testing Library 测试应优先使用角色查询,而不是类名查询。

按 slider 角色查找句柄。

当前测试仅确认带有 rc-slider-handle 类名的元素具有属性。如果句柄失去 role="slider",这些无障碍测试仍会通过。请用 getAllByRole('slider') 取得句柄后保留现有属性断言。Based on learnings:React Testing Library 测试应优先使用角色查询,以验证用户和辅助技术可识别的元素。

Thanks! Implementation looks clean and consistent with the existing aria props. Two minor suggestions:

  1. Type asymmetry: ariaInvalid is boolean only, while ariaInvalidForHandle accepts AriaInvalid (including 'grammar' / 'spelling'). Since the AriaInvalid type exists, consider allowing it on ariaInvalid too, so a global 'grammar' doesn't need an array workaround.
  2. Out-of-range fallback: with ariaInvalidForHandle={[true]} on a range with 2 handles, the 2nd handle gets no aria-invalid at all. Omitting it is equivalent to false in HTML so it's fine, but worth documenting — or fall back to ariaInvalid via getIndex(...) ?? ariaInvalid.

将 ariaInvalid 的类型改为 AriaInvalid。

中文 API 表当前只写 boolean,遗漏了 grammar 和 spelling。这与公开类型和英文 API 文档不一致,会误导中文 README 用户。

建议修复
-| `ariaInvalid` | boolean | - | 句柄元素的 `aria-invalid`。 |
+| `ariaInvalid` | `AriaInvalid` | - | 句柄元素的 `aria-invalid`。 |
