我有带有多个不同颜色标记的地图和一些信息窗口。一切正常，除了当我单击某个标记（例如我有 5 个）时，它会打开我的光标，比如说，第 4 个标记并始终从该标记显示信息窗口。所以它总是显示相同的信息窗口。这是一个小的 html 文件，所以如果有人知道解决方案，我将不胜感激。我也尝试过，google.maps.event.addDomListener因为我认为存在问题，但行为相同。

只需将您的代码更改为此，以便它为每个元素获取正确的 url。

<a href="' + html;

到

<a href="' +markers[i].getAttribute("html");

所以你的问题的完整代码是：

google.maps.event.addListener(marker, 'click', (function(marker, i) { return function(){ var alarmanchor1='<span class="url"><a href="' +markers[i].getAttribute("html"); var alarmanchor2='" title="www" target="_blank">Event List</a></span>'; var contentString=alarmanchor1+alarmanchor2; infowindow.setContent(contentString); infowindow.open(map, marker); } }) (marker, i));
