【原生小程序小程序开发中，块内容使用position绝对定位之后 不显示】

原来写法

<view class="map_bg" id="weixinMap" bindtap="event" style="display: none;">
        <map subkey="{{subKey}}" style="width:100%;height:100%;z-index: -10;"  latitude="23.099994" longitude="113.324520" scale="18" enable-zoom="{{false}}" enable-scroll="{{false}}">
        </map>
        <view class="map_company flex_start">
          <image class="map_site" src="../../public/images/companyshow/tc_icon.png"></image>
          <view class="company">
            <view class="companyname omit">{{base_info.companyname}}</view>
            <view class="district omit">{{base_info.district_text}}</view>
          </view>
          <view class="arrow_right"></view>
        </view>
      </view>
      <view class="address address_distance">
        <image class="map_site" src="../../public/images/jobshow/address.png"></image>
        {{distance||'计算中'}}
      </view>

.company_item .map_company{
padding: 10rpx;
width: 550rpx;
 height: 80rpx;
 border-radius: 8rpx;
 background: #fff;
 position:absolute;
 top:-50%;
 left:-50%;
 transform:translate(-50%,-50%);
 color: #000;
 }

解决：在map外面包一层以及整体在外面包一层+定位修改为static+z-index

<view>
        <view class="map_bg" id="weixinMap" bindtap="event">
            <map subkey="{{subKey}}" style="width:100%;height:100%;z-index: -10;" latitude="23.099994" longitude="113.324520" scale="18" enable-zoom="{{false}}" enable-scroll="{{false}}">
            </map>
        </view>
        <view class="map_company flex_start">
          <image class="map_site" src="../../public/images/companyshow/tc_icon.png"></image>
          <view class="company">
            <view class="companyname omit">{{base_info.companyname}}</view>
            <view class="district omit">{{base_info.district_text}}</view>
          </view>
          <view class="arrow_right"></view>
        </view>
      </view>
      <view class="address address_distance">
        <image class="map_site" src="../../public/images/jobshow/address.png"></image>
        {{distance||'计算中'}}
      </view>

.company_item .map_company {
  padding: 10rpx;
  width: 550rpx;
  height: 80rpx;
  border-radius: 8rpx;
  background: #fff;
  position:static;
  margin: -23% auto 0;
  z-index: 1000;
  color: #000;
}
