javascript - 打印时加载 map 标记问题

Question

我能够在 map 上指向标记，并且它在浏览器中可见。但是当我打印相同的内容时，标记在 map 上不可见。请帮忙。

<button class="map-print" ng-click="mapprint();">print</button>
[enter image description here][1]<script>
function mapprint(){
    var content = document.getElementById('map_div'); //has to be first. 
    content.style.position = "relative"; 
    content.style.height = contents.firstChild.offsetHeight + "px"; 
    content.style.width = contents.firstChild.offsetWidth + "px"; 
    var win = window.open(); 
    win.document.write(content.innerHTML);
    win.print();
    win.close();    
}

我得到了 map 的打印件。但是无法加载 map 标记

Google Maps JavaScript API 不支持打印。看看官方常见问题解答中的以下答案

https://developers.google.com/maps/faq#print

Printing from the JavaScript API is not supported. This is because printing support is inconsistent across commonly used browsers. We recommend using the Static Maps API for printing purposes.
