Walkthrough

此次更改在useTarget函数中引入了新的内部函数calculatePosition，用于计算和更新目标元素的位置。通过使用IntersectionObserver来观察targetElement的可见性，更新逻辑在元素进入视口时通过300毫秒的延迟触发位置计算。这种模块化方法改善了代码的可读性和可维护性。

在兔子洞中蹦跶跳，
新功能来得真巧妙！
位置计算更灵敏，
可见性观察更安心。
代码清晰如晨曦，
维护起来真轻松！ 🐰✨

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>.
  • 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @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.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.

45-55: 封装位置计算逻辑的实现很好！

calculatePosition 函数将位置计算逻辑封装起来，提高了代码的可读性和可维护性。

---

60-71: 使用 IntersectionObserver 优化视图更新逻辑！

使用 IntersectionObserver 来观察目标元素的可见性，并在元素进入视图时触发位置计算，这是一个很好的改进。300 毫秒的延迟有助于确保滚动完成。

---

73-77: 确保在组件挂载和窗口调整大小时更新位置。

在 useLayoutEffect 中调用 updatePos 确保了在必要时重新计算位置，并且在组件卸载时移除事件监听器，保证了资源的正确释放。
