产品也真是够了，周选择、月份选择、年份选择都是 antd 直接支持的，然而他现在要求要季度选择和半年份的选择。
那就来实现一个仿 antd 风格的季度选择组件吧，本文部分参照博客园-真的想不出来-模仿 Antd 写一个季度的时间选择器 V1.0
我实现了复制可用的版本。
效果
功能：
- 一个纯组件，并且是 ts 版本。
- 可以切换年份
- 点选某个季度，执行 props 传入的 onChange 函数，value 参数形如 "2019-Q2"
- 点击外部收起下拉框
- 支持 value 传入默认选择项并定位到此。
调用
<QuarterPicker value={selectStartMonth} onChange={this.startDataChange} style={{marginRight: 24}}></QuarterPicker>
startDataChange(data: any) {
dispatch.dataQueryDistributorDot.SET({
selectStartMonth: data
});
}
代码
-- 第二次更新 --
补充了 ts 的一些类型说明，并且将 componentWillReceiveProps(nextProps, prevState) 替换为 static getDerivedStateFromProps(nextProps, prevState)，因为前者即将被 React 废弃。
