Walkthrough

本次变更主要针对 PickerView 组件及其子组件的渲染和选择逻辑进行了优化。具体包括在 pickerroller 组件的列表渲染中，将 React Fragment 的 key 属性移至外层 Fragment，以提升 React 的元素对比效率；同时在 pickerview 相关组件的 handleSelect 回调中，改用 isEmpty 工具函数替代简单的 falsy 判断，确保对空值的判断更准确，避免误判。其余业务逻辑和导出接口未发生变动。

Changes

文件/路径	变更摘要
src/packages/pickerview/pickerroller.taro.tsx	将列表渲染时的 React Fragment 替换为带 key 的 <React.Fragment>，key 从内层 View 移至 Fragment。
src/packages/pickerview/pickerview.taro.tsx src/packages/pickerview/pickerview.tsx	在 handleSelect 回调中，将对新值的空判断由简单的 falsy 检查改为调用 isEmpty 工具函数，提升判断准确性。

代码如风吹柳梢头，
Fragment 加 key 更顺手。
选择零值不再愁，
逻辑清晰无遗漏。
小兔子跳跃来巡游，
组件优化乐悠悠！

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
