wxaSortPicker小程序首字母排序选择器

wxaSortPicker

版本号1.0.1 
github地址: https://github.com/nickrogit/wxaSortPicker 
说明:小程序首字母排序选择器,网上有不少但觉得不太好,自己优化改进的这款觉得还不错,后面再慢慢完善丰富。

 

版本说明

1.0.0版本仅支持字符串数组 
1.0.1版本加入json数组支持,如:[{name:'中国',value:'China'},{name:'美国',value:'America'}],value取值e.target.dataset.value,其他不变

 

功能

字符串数组首字母排序 
右侧点击字母定位 
点击item返回数据

 

开发要点

解析汉字Unicode编码并排序 
小程序scroll-view组件的scroll-into-view属性,点击右侧字母改变scroll-into-view的属性值,定位。 
scroll-into-view(值应为某子元素id(id不能以数字开头)。设置哪个方向可滚动,则在哪个方向滚动到该元素),

 

适用场景

城市、国籍、通讯录等字母排序
