Openlayer - 无法在标记上绑定弹出窗口

Question

我尝试为标记创建弹出窗口。但它在地图的其他地方显示，如图所示。 在这种情况下有点困惑。 请给我解决方案。

JS我试过的代码

var newlonLat = new OpenLayers.LonLat( Lon1, Lat1 )
    .transform( new OpenLayers.Projection("EPSG:4326"),
        map.getProjectionObject() // to Spherical Mercator Projection
        );
    var zoom=9;
    var newmarkers = new OpenLayers.Layer.Markers( "Markers" );
    map.addLayer(newmarkers);
    newmarkers.addMarker(new OpenLayers.Marker(newlonLat));
    map.setCenter (newlonLat, zoom);


    popup = new OpenLayers.Popup("chicken",
        new OpenLayers.LonLat(Lon1, Lat1),
        new OpenLayers.Size(200,200),
        "example popup",
        true);

    map.addPopup(popup);

Answer 1

我认为您对弹出窗口进行了错误的协调。您是否尝试过这样定义弹出窗口？：

popup = new OpenLayers.Popup("chicken", 
newlonLat, 
new OpenLayers.Size(200,200), 
"example popup", 
true);
