Summary

In accordance with the W3C WAI-ARIA Accordion Pattern, accordion headers (role="button" / role="tab") should support activation via both Enter and Space. Furthermore, pressing Space should prevent default browser scrolling (e.preventDefault()).

Changes

  • In src/Panel.tsx:
    • Guard disabled at the beginning of onKeyDown to prevent keyboard interaction when disabled.
    • Support Space key (e.key === ' ' || e.key === 'Spacebar' || e.keyCode === KeyCode.SPACE || e.which === KeyCode.SPACE) to toggle panel and call e.preventDefault().
  • Added unit test in tests/index.spec.tsx verifying Space key activation, preventDefault(), and disabled panel guard.

Summary by CodeRabbit

  • 功能改进

    • 面板启用时,按空格键可打开或关闭面板;按键不会触发浏览器默认行为。
    • 面板禁用时,键盘操作不会触发点击。
  • 测试

    • 增加了对上述空格键交互的验证。

Walkthrough

面板的 onKeyDown 现在会在面板禁用时忽略键盘事件,并支持通过空格键触发面板点击。新增测试覆盖禁用面板、阻止默认行为以及打开和关闭面板。

Space can no longer activate a button in the panel header’s extra content and instead toggles the panel. Fix this before merging.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

只处理标题触发元素自身的 Space 键事件。

当 extra 包含获得焦点的按钮时,按钮的 Space 键事件会冒泡到标题容器。此处调用 preventDefault() 并切换面板,会取消按钮的默认操作。请在处理前确认 e.target === e.currentTarget,并增加嵌套按钮的回归测试。WAI-ARIA Accordion Pattern 也将 Space 键切换限定于焦点位于折叠标题的情况。(w3.org)
