模仿 Antd 写一个季度的时间选择器 V2.0

时间:2020-01-19 17:27:11      阅读:480      评论:0      收藏:0      [点我收藏+]

说明:

版本:V2.0

此文章代码复制不可用。代码真多,编辑不易。有需要联系我,谢谢。

功能介绍:

1.可以设置 可选择的时间范围,范围超出部分置灰不可选择。

2.点击空白处默认收起弹窗,也可以在外部通过 open 属性控制。

3.按确定按钮后过 onOk 属性返回 一个函数,第一个参数为选择的时间。

4.*新增:用户可以选择是否使用确定按钮。

5.*新增: disabled (禁用状态)、className (设置选择器)、defaultValue(时间为空时的默认显示) 。

改进方向:

此版本基本满足开发时的各种需要,及突发情况。目前暂无改进计划。

观众老爷们若有什么好的建议,我也会采纳,主要是得有时间。??
