1-1: 建议优化 ESLint 禁用规则的范围当前的 ESLint 禁用指令范围过大。建议仅针对特定行或代码块禁用必要的规则，以保持代码质量。
建议修改为：
-/* eslint-disable no-undef, react/no-multi-comp, no-console */ +/* eslint-disable-next-line react/no-multi-comp */
8-8: 建议优化测试用例名称当前测试名称 "keep sync" 不够具体。建议使用更描述性的名称来反映测试的具体目的和预期行为。
建议修改为：
- it('keep sync', async () => { + it('should maintain data consistency when loading nodes incrementally', async () => {
18-29: 建议增加更多测试场景当前的
loadData实现过于简单，没有覆盖足够的边界情况。建议添加以下测试场景：
- 加载失败的情况
- 叶子节点的处理
- 异步加载超时
建议添加如下测试数据变体：
const loadData = async () => { const nextId = treeData.length; // 模拟随机延迟 await new Promise(resolve => setTimeout(resolve, Math.random() * 100)); setTreeData([ ...treeData, { title: `${nextId}`, value: nextId, isLeaf: nextId > 3, // 第三层后设置为叶子节点 }, ]); };

1-46: 验证测试用例是否充分覆盖 PR 目标
该测试用例验证了 TreeSelect 组件的数据加载同步性，这与 PR 的主要目标（修复 loadData 不保持新鲜度的问题）相关。但是，建议增加以下测试场景以更全面地验证修复：
- 验证第三层节点数据是否正确加载（对应 issue #51724）
- 验证数据在异步加载过程中的状态保持
- 测试快速展开/折叠节点时的数据一致性
运行以下脚本以检查是否有其他相关测试：
✅ Verification successful
测试覆盖度已经足够充分
经过验证，现有测试用例已经全面覆盖了 loadData 相关功能：
Select.loadData.spec.tsx验证了数据加载的同步性和状态保持Select.SearchInput.spec.js测试了搜索场景下的数据加载行为Select.props.spec.js验证了loadData属性的基本功能和treeLoadedKeys的交互
现有测试组合已经充分覆盖了 PR 的修复目标，无需添加额外的测试场景。

13-13: 导入语句正确添加！
引入 useEvent hook 是一个好的做法，它可以帮助保持函数引用的稳定性，避免不必要的重渲染。
245-246: 使用 useEvent 包装 loadData 是个很好的优化！
通过 useEvent 包装 loadData，可以确保：
- 函数引用在重渲染之间保持稳定
- 始终能获取到最新的 props/state
- 减少不必要的重渲染
这个改动直接解决了 PR 中提到的 "loadData not keep fresh" 的问题。
Line range hint 247-252: 建议验证优化逻辑的正确性
loadDataFun 的更新逻辑变得更加复杂：
- 使用
syncLoadData替代了直接的loadData引用 - 依赖数组中添加了
treeExpandedKeys - 比较函数的逻辑需要仔细验证
请运行以下脚本验证相关测试用例：
建议：
- 确保在搜索值变化时正确处理异步加载
- 验证
treeExpandedKeys变化时的展开/加载行为
可以考虑添加注释说明比较函数的具体作用：
loadDataFun = useMemo(
() => (searchValue ? null : (syncLoadData as any)),
[searchValue, treeExpandedKeys || expandedKeys],
+ // 仅在搜索值变化或展开键变化时更新
+ // nextExcludeSearchExpandedKeys 表示非搜索状态下的展开键
([preSearchValue], [nextSearchValue, nextExcludeSearchExpandedKeys]) =>
preSearchValue !== nextSearchValue && !!(nextSearchValue || nextExcludeSearchExpandedKeys),
);✅ Verification successful
Let me gather more information about the test cases and implementation to verify the optimization logic.
Based on the test implementation and source code analysis, I can now provide the final response:
优化逻辑验证完成，实现符合预期
经过验证，loadDataFun 的优化逻辑是合理的：
- 测试用例
Select.loadData.spec.tsx验证了异步加载的正确性和同步性 syncLoadData的使用确保了事件处理函数的稳定性- 比较函数的逻辑正确处理了搜索状态和展开状态的变化
建议保留当前实现，无需额外修改。
