微信小程序picker-view自定义日期时间等

picker-view 可以自定义地区时间什么的，其实主要是可以修改样式啦。

<view class='login-user border-none' bindtap='data_click'>
      <view class='user-t'>生日</view>
      <view class='user-i'>
        <input placeholder="请输入生日" disabled value='{{birthday}}' />
      </view>
      <view class='header-jian'>
        <image src='../../img/jiantou.png'></image>
      </view>
    </view>
