推荐答案

您的意思是KML文件更新? 您是从数据库中生成KML，以便进行更新意味着将更多的点插入到数据库中吗?

What to you mean KML-file updates? Are you generating the KML from your database so updates means that more points are inserted to your db?

无论如何，您可以构造浏览器以定期询问服务器此KML是否已更新，检索并最终从地图上删除过期文件并显示新文件.

Anyway if that's the case you can construct the browser to periodically ask the server if this KML is updated,retrieve it and finally remove the expired file from the map and show the new.

据我所知，您无法自动"同步" KML叠加层.

Because as far as i know there is no way you can "sync" the KML overlay automatically.
