            @markertap="onMarkerTap" @callouttap="onMarkerTap">  
            <!-- 自定义callout模板 -->  
            <cover-view slot="callout">  
                <cover-view v-for="(point, index) in points" :key="index" class="custom-callout"  
                    :marker-id="point.id">  
                    <cover-image src='/static/jianbianBackground.png' class="callout-img"></cover-image>  
                    <cover-view class="callout-icon">  
                        <cover-image src="/static/pijiu.png" style="width: 100%;height: 48rpx;"></cover-image>  
                    </cover-view>  
                    <cover-view class="callout-content">  
                        <cover-view class="callout-title">{{ point.title }}</cover-view>  
                        <cover-view class="callout-location">{{ point.description }}</cover-view>  
                    </cover-view>  
                    <cover-view class="callout-icon">
