日期Picker 代码补全

https://blog.youkuaiyun.com/cchhzzyy/article/details/82886823

以上是作者原代码出处，但是实际用的时候代码不够完全。这里补充说明

// wxml 代码

<view wx:if="{{isShowDates}}" class="showDates">
 <modal show="true" height='60%;width:100%' bindcancel="" bindconfirm=''>
      <view class="time_text">{{year}}-{{month}}-{{day}}</view>
      <view class="time_title">
        <view class="time_title_text">年</view>
        <view class="time_title_text">月</view>
        <view class="time_title_text">日</view>
      </view>
    
      <picker-view wx:if="{{years.length>0 && months.length>0 && days.length>0}}"  indicator-style="height: 50px;" class="view_picker" style="width: 100%;" value="{{value}}" bindchange="bindChange" >
     <!--  <text>{{years}}</text>
      <text>{{months}}</text>
      <text>{{days}}</text> -->
          <picker-view-column class="view_picker_column">
            <view wx:for="{{years}}" class="view_picker_text" wx:key="{{index}}">{{item}}</view>
          </picker-view-column>
          <picker-view-column class="view_picker_column">
            <view wx:for="{{months}}" class="view_picker_text" wx:key="{{index}}">{{item}}</view>
          </picker-view-column>
          <picker-view-column class="view_picker_column">
            <view wx:for="{{days}}"  class="view_picker_text" wx:key="{{index}}">{{item}}</view>
          </picker-view-column>
      </picker-view>
  </modal>
</view>

     这里绑定一个 bindtap 事件让 isShowDates 为 true 即可。

// wxss 代码：

.time_text{
  text-align: center;
}
.showDates{
  position: fixed;
  width: 80%;
  height: 80%;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  font-size: 36rpx;
  z-index: 9999;
}
.time_title{
  display: flex;
  flex-direction: row;
  justify-content: space-around;
}
.view_picker{
  height: 300rpx;
}
.view_picker_text{
  color: #000;
  font-size: 40rpx;
  text-align: center;
  line-height: 100rpx;
}

至于说没有弹框啥的，一般是自定义 Modal 

最后效果是：（要完全和原作者一样，好像不太对。modal 模版下面的 "取消"+"确认" 不能删掉，这个是元素自带的）
