Fixes #1018

Problem: a date rejected by disabledDate is not reverted when the input is blurred (the popup closes) — the input keeps showing it while the committed value was never updated. Pressing Enter for the same input works.

Why: resolveAction decides the action before the submit happens, so it cannot know the submit will be rejected. On the blur path the popup close is what triggers the submit; after the rejection reset() only clears the bookkeeping and leaves the temporary value behind, and switchNext is a submit action, so nothing ever reaches resetValue. Enter only works by accident: its close event arrives one step later and lands on the currentIndex === null branch.

Changes

  • flushSubmit now reports the submit result (boolean | void), and submitField discards the temporary value when it comes back false — equivalent to running resetAll on the spot.
  • preserveInvalidOnBlur keeps the previous behaviour by skipping that discard (the default is to discard).
  • RangePicker goes through the same path and is covered as well.

Tests in tests/blur.spec.tsx: rejected → reverted,

Summary by CodeRabbit

  • 修复
    • 关闭日期选择弹窗时,未通过校验的日期会恢复为原值,且不会触发变更;启用保留无效值设置时也如此。
    • 通过校验的日期会保留,并触发变更。

A field submitted by closing the popup kept its temporary calendar value
when the submit was rejected by disabledDate, so the selector displayed a
value the committed value never accepted. Blur and Enter also behaved
differently for the same input, since Enter's close event arrives one step
later and lands on the `currentIndex === null` branch.

Let `flushSubmit` report whether the flushed value was accepted, and reset
the temporary value inside `submitField` when it was rejected. Consumers
that explicitly ask for the typed text to survive blur
(`preserveInvalidOnBlur`) keep the previous behaviour.

Walkthrough

单日期和范围日期选择器现在会返回字段提交的校验结果。提交被拒绝时,值变更流程会重置临时值。新增测试覆盖被拒绝日期恢复原值,以及获准日期保留并触发 onChange。

`preserveInvalidOnBlur` only covers text that cannot be parsed, so a date
rejected by `disabledDate` is discarded on blur either way. Drop the
exception that was added for it and pin the behaviour with a test.

为 RangePicker 增加被 disabledDate 拒绝时的关闭回归测试。

当前新增测试只覆盖 DayPicker。现有 RangePicker 测试只输入不可解析文本,不会验证被 disabledDate 拒绝的可解析日期是否恢复,也不会验证 onChange 未触发。

如果 RangePicker 的 flushFieldSubmit 遗漏返回 flushSubmit 的 false,submitField 会跳过 resetValue()。现有测试仍可能通过,因此该 bridge 的行为没有受到保护。

`RangePicker.flushFieldSubmit` forwards the submit result, but nothing
exercised it, so dropping the forwarded value would restore the original
bug without failing any test.

分别覆盖 start 和 end 的拒绝路径。

当前用例同时拒绝两个临时日期,并只关闭 end 弹窗。end 被拒绝后,整个 range 会被重置,因此即使 start 的拒绝校验失效,该用例仍可能通过。

请分别运行只拒绝 start 和只拒绝 end 的场景。两个场景都应断言两个输入恢复原值,且 onChange 未调用。

Rejecting both temporary dates at once only proves that the range as a
whole is discarded; running the rejected start and the rejected end
separately covers each side of the check.

结论先行

⚠️ 有条件合并 — blur 的核心修复有效,但详细对照发现了非关闭场景的行为变化:RangePicker 切换字段时,会丢弃另一端合法的未提交日期。建议先收窄这条路径的回退范围并补回归测试,再合并。

本轮审查基于 head 53e030f。目前不能给出“没有非预期变化”的结论。

主要变更内容

将最终提交结果传回交互层

useRangeValue、SinglePicker、RangePicker 将校验结果返回给统一交互 hook;只暂存字段时仍返回 undefined。

  if (needTriggerChange) {
-   triggerSubmit();
+   return triggerSubmit();
  }

SinglePicker 和 RangePicker 的 flushFieldSubmit 随后继续返回该结果。

在公共提交入口恢复被拒绝的日期

useRangeValueChange 收到 false 后,先恢复日期,再执行原有的交互记录清理:

- flushSubmit(index, allFieldsTriggered);
+ const accepted = flushSubmit(index, allFieldsTriggered);
+ if (accepted === false) {
+   resetValue();
+ }

  if (allFieldsTriggered) {
    reset();
  }

影响边界是“最终提交失败”,没有限制为 popupClose。不带参数的 resetValue() 会恢复整组日期和待提交值,并可能发出恢复原值的 onCalendarChange;submitField 的返回值、字段推进和焦点规则保持原逻辑。

另有 1 个测试文件更新,新增 5 个用例。PR 描述称 preserveInvalidOnBlur 会跳过回退,但当前代码和测试均会回退被业务校验拒绝的日期,描述需要同步。

验证结果与影响范围

检查 结果
仓库全量单测 base:505 通过;head:510 通过;两侧均跳过 2 个,29 个快照通过
TypeScript base / head 均通过
补充 base/head 对照 168 个场景,两侧均执行通过;129 个结果完全一致,39 个存在差异
正常提交及既有交互 已覆盖的合法提交、确认、清空、预设、多选删除、拒绝后重新输入合法值均正常
弹窗、焦点及回调 对照中未发现弹窗状态、焦点及 onChange、onOpenChange、onOk 等变化;差异集中在拒绝后的日期展示、错误状态和 onCalendarChange
单独的草稿保留回归用例 base 通过,head 失败,见下方问题

对照覆盖受控/非受控日期、父组件更新值、受控 open=true、Enter、Tab、blur、字段切换、日期与时间禁用、顺序、allowEmpty、禁用单端、无效文本保留、多选删除,以及 Moment 格式适配。

需要明确的额外变化:

  • RangePicker 字段切换失败时,弹窗可以仍然打开,但两端草稿已经整体回退。
  • 受控 open=true 时,Enter / Tab 校验失败也会立即回退,不需要实际关闭弹窗。
  • 已有多选值包含禁用日期时,关闭状态下删除另一个标签若提交被拒绝,标签显示也会恢复。
  • 回退会通知 onCalendarChange,因此不能将影响理解为只修改输入框文本。

RangePicker 只编辑一端再 blur 的遗漏在 base/head 上都存在,属于既有缺陷,本次没有修复。

远端测试工作流仍为 action_required,尚未实际执行,不能视为 CI 已通过。

问题清单(按重要程度排序)

🔴 高优先级(阻塞合并)

无。

🟡 中优先级(建议修复)

  • [P2] 切回输入框修正错误时,会丢弃另一端合法草稿 — src/PickerInput/hooks/useRangeValueChange.ts:237

    初始范围为 [2026-06-15, 2026-06-20],将起始日期改为禁用的 2026-03-15、结束日期改为合法的 2026-06-25,再点击起始输入框继续修正。此时弹窗仍打开,但 field-switch → switchNext → submitField 的失败结果触发整组 resetValue(),合法的结束日期也从 06-25 恢复成 06-20;同一复现用例(见下方代码)在 base 通过、head 失败。

    建议把本次整体回退限制在 popupClose 等实际结束编辑的路径,保留字段切换中仍待修正的草稿,并补上该回归用例。

最小复现测试:base 通过,PR head 失败

在现有 tests/range.spec.tsx 的测试环境中:

it('keeps the valid pending end while correcting an invalid start', async () => {
  const onChange = jest.fn();
  const { container } = render(
    <DayRangePicker
      defaultValue={[getDay('2026-06-15'), getDay('2026-06-20')]}
      disabledDate={(date) => date.isBefore(getDay('2026-06-01'), 'day')}
      onChange={onChange}
    />,
  );
  const [start, end] = container.querySelectorAll('input');

  openPicker(container, 0);
  fireEvent.change(start, { target: { value: '2026-03-15' } });
  openPicker(container, 1);
  fireEvent.change(end, { target: { value: '2026-06-25' } });

  triggerFocus(start);
  await waitFakeTimer();

  expect(isOpen()).toBe(true);
  expect(document.activeElement).toBe(start);
  expect(onChange).not.toHaveBeenCalled();
  expect(end).toHaveValue('2026-06-25');
  // PR head: received '2026-06-20'
});
