所以，问题是出在哪里了？

[orzyyyy]

getDerivedStateFromProps 里判断 props 里有 mode 就更新 state， 然后 defaultProps.mode 始终都是 month，也就是 Header 的 onChange 始终没法改变外部的 mode

实际上去掉这个 defaultProps 就完了，其它改动是因为 type 老是变来变去，实在头疼就改了

测试用例在补，不要慌

话说这个组件用的人真少，居然都没人报 bug。

[orzyyyy]

何不弄个问卷，或者直接在文档网页上弄个点击统计

不但方便路人看热闹，自己还能看到哪些组件该重点维护

这组件出问题我还是在写测试用例的时候发现的

3.1.4.x 是好的：https://codesandbox.io/s/m9ol1o05nj

感觉迁移 lifecycle j经常遇到这类问题，合之前需要多点点 😄

- const mode = type === 'date' ? 'month' : 'year';
- if (this.state.mode !== mode) {
-     this.setState({ mode });	
-     this.onPanelChange(this.state.value, mode);	
- }

+ setType = (mode: CalendarMode) => {
+   this.setState({ mode });
+   this.onPanelChange(this.state.value, mode);
+ }

感觉 type 也没什么用了，全部统一掉吧:

• mode => type
• setType => setMode
• onHeaderTypeChange => onHeaderModeChange
