Question

我正在为WordPress使用高级自定义字段的谷歌地图插件。我在地图上有多个点，有些点非常接近。我可以打开他们没有问题，但我需要一次打开。因此，如果我打开一个，它会关闭其他的。单击高级自定义字段时设置的标记如下：

if( $marker.html() )
{
    // create info window
    var infowindow = new google.maps.InfoWindow({
        content     : $marker.html(),
        maxWidth: 250
    });


    google.maps.event.addListener(marker, 'click', function() {
        infowindow.open( map, marker );
    });     
}

任何有关如何附加此内容的帮助，一次只打开一个窗口将非常感谢
