删除标记后如何删除InfoWindow？

Question

我有一个Google Maps div和复选框列表,用于过滤地图上的标记.

但是,如果我单击标记,打开一个InfoWindow,然后单击复选框以删除该类型的标记,InfoWindow则不会从地图中删除.

删除标记后,我调用此代码,但InfoWindow保留:

try {
    if( infowindow ) {
          infowindow.close();
    }
}
catch(err) { }

Answer 1

function closeInfoWindow() {
        if (infoWindow !== null) {
            google.maps.event.clearInstanceListeners(infoWindow);  // just in case handlers continue to stick around
            infoWindow.close();
            infoWindow = null;
        }
    }

Answer 2

我建议您更改创建Marker单击侦听器的代码,通过添加类似于以下示例的代码来打开InfoWindow:

google.maps.event.addListener( marker, "click", function() {
    var bubble = new google.maps.InfoWindow({
        content: buildBubbleContent( param1, param2 )
    });
    bubble.open( map, marker );
    //pretty standard stuff to here, but the next line is new (for me):
    google.maps.event.addListenerOnce( marker, "visible_changed", function() {
        bubble.close();
    });
});

正如所讨论的那样:当隐藏相关标记时,如何清理InfoWindow？:
