Question

我是google地图和php的新手，假设我在地图上有100个标记，我想从它们中选择15个标记，如果标记点击它会改变标记的颜色并做一些动作。在此代码中如果我单击标记，它只显示从数据库获取数据的弹出窗口。

这是我的谷歌地图初始化代码使用PHP ..任何帮助的朋友

试试这个（在你的代码中，在第40行附近）：

google.maps.event.addListener(marker, "click", function() {
  this.setIcon({url: 'http://maps.google.com/mapfiles/ms/micons/purple.png'});
});
