摘要:一个支持范围选择的日历移动端需求原型日历默认显示当前月,并且标注当日的日期,当日以后得日期置灰不可以选择。日历支持选择某单个日期和范围选择,并且选中的两个日期之间要加背景色。
一个支持范围选择的日历(移动端)
需求原型:
1、日历默认显示当前月,并且标注当日的日期,当日以后得日期置灰不可以选择。
2、日历支持选择某单个日期和范围选择,并且选中的两个日期之间要加背景色。
3、限制最多选择6个月,超出六个月提示“最多选择6个月”,并且日历滚动到选择的起始日期位置,保留开始日期的选中效果,继续选择结束日期。
4、在显示周的元素下面,要有个显示当前滚动到的年月的元素并带有动画效果。
demo采用的是rem布局。
需求大概就是这个样子,下面贴代码咯:
具体实现逻辑
index.html
日历 Document 日历范围选择
最多可选六个月,请重新选择!
