javascript - Openlayer - 无法在标记上绑定(bind)弹出窗口

Question

我尝试为标记创建弹出窗口。但它显示了 map 中的其他一些位置，如图所示。在这种情况下有点困惑。请给我解决方案。

JS 我尝试过的代码

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的协调是错误的。您是否尝试像这样定义弹出窗口？:

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