Question

经过大量研究后，我无法确定为何在打开新窗口时无法关闭InfoWindow。到目前为止，我尝试过的所有内容都导致InfoWindow根本无法显示。

我在这里尝试了一些建议：Google Map API v3 ~ Simply Close an infowindow?和其他地方，但我想知道这是否是一个我不知道导致这个问题的问题。不可否认，这是从其他来源拼凑而成的。非常感谢你的帮助。

您只能使用一个infowindow对象并动态设置不同的内容

例如： var infowindow = new google.maps.InfoWindow（{maxWidth：200}）;

为您的标记添加监听器

var marker = new google.maps.Marker({
   map: map,
   info: 'this is info window html',
   position: results[0].geometry.location
});

google.maps.event.addListener(marker, 'click', function() {             
     infowindow.setContent(this.info);
     infowindow.open(map, this);
     map.setCenter(this.getPosition());
});

在打开新的InfoWindow时关闭每个InfoWindow
