农历日期组件 【恋人小清单开发总结】
因为我过农历生日，所以开发了这个功能哈哈哈哈
自己说了算的感觉真好
言归正传
官方的日期组件不支持农历，所以需要借助官方的多列选择器做扩展
因为农历有闰年的缘故，在选择了年份后需要更新月份，选择了月份以后需要更新日期
另外一个需要注意的是闰年的情况下，多列选择器月份选中的索引需要注意一下，如果在闰月之前的月份索引需要减一，闰月之后的月份不需要减一
比如农历2020的四月，对应的月份索引应该等于3，闰4月对应的索引等于4.看下图片就明白了
看下效果图：
可以扫码体验
1、wxml代码
这里用到官方的多列选择器
<picker style="text-align: right;" data-type="lunar" name="lunarPicker"
bindchange="multiPickerChangeHandler"
bindcolumnchange="selectMultiPickerColumnHandler"
mode="multiSelector"
value="{{lunarDateRangeIndex}}"
range-key="text"
range="{{lunarDateRange}}">
<input readonly disabled placeholder="选择日期" placeholder-class="edit-placeholder" value="{{lunarDate}}"/>
</picker>
