自己修改源的源码更加方便好用！粘贴即用，不明白的可以问我wx: xin32934

Mdate.js

是一款依托于iScroll.js的日期选择小型插件，可滑动选择年、月、日，只适用于移动端。
操作简易，只需要在页面中引入iScroll.js和Mdate.js即可。

使用说明

new Mdate("dateShowBtn", {
//"dateShowBtn"为你点击触发Mdate的id，必填项
acceptId: "dateSelectorTwo",
//此项为你要显示选择后的日期的input，不填写默认为上一行的"dateShowBtn"
beginYear:'',
//此项为Mdate的初始年份，不填写默认为当前及以前的日期
beginMonth: '',
//此项为Mdate的初始月份，不填写默认为当前及以前的日期
beginDay: "",
//此项为Mdate的初始日期，不填写默认为当前及以前的日期
endYear: "",
//此项为Mdate的结束年份，不填写默认为当年
endMonth: "",
//此项为Mdate的结束月份，不填写默认为当月
endDay: "",
//此项为Mdate的结束日期，不填写默认为当天
format: "yyyy-mm",
//此项为Mdate需要显示的格式，可填写"/"或"-"或".",不填写默认为年月日 
success:function(e){//点击确定按钮回调
    alert(e)//弹出选择的时间
  }
  })
