Question

我有多个不同颜色标记的地图和一些信息窗口。一切正常，除非我点击一些标记（例如我有5个标记），它会打开光标，比方说，第4个标记，并始终从该标记显示信息窗口。因此它始终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。我也尝试使用google.maps.event.addDomListener因为我认为存在问题，但它是相同的行为。

Answer 1

只需将代码更改为此代码，即可为每个元素获取正确的网址。

<a href="' + html;

到

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

所以问题的完整代码是：

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));

Google Map奇怪的行为标记信息窗口始终显示来自同一标记的信息
