The KML file has no attributes for the displayed features (Placemark). Only the document and the folder has attributes, but this one not added to the feature(s).
That will work: <Placemark> <name>La Roquebrussanne</name> <description>Provence</description> <Point> <coordinates>665231.4570703981,5363853.803594344</coordinates></Point></Plac emark> Arnd -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Wyo Gesendet: Sonntag, 9.

When I set a breakpoint with firebug in onFeatureSelect and check the content of the feature, the attributes exist but is empty. Where's my error or is there something missing in the KML file (see below)? layers[i] = new OpenLayers.Layer.Vector (canals[i][1], { strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.HTTP({ url: "data/relation_"+canals[i][0]+".kml", format: new OpenLayers.Format.KML({extractAttributes: true, extractStyles: false}) }), projection: map.displayProjection, eventListeners: { "featureselected": onFeatureSelect, "featureunselected": onFeatureUnselect, scope: this }, styleMap: styles }); styles = new OpenLayers.StyleMap ({ "default": new OpenLayers.Style({ label: "${name}", fillColor: "#ffcc66", strokeColor: "red", strokeWidth: 3 }), "select": new OpenLayers.Style({ label: "${name}", fillColor: "#66ccff", strokeColor: "blue", strokeWidth: 5 }) }); function onFeatureSelect(event) { var feature = event.feature; // Since KML is user-generated, do naive protection against Javascript. var content = "<h2>"+feature.attributes.name + "</h2>"; if (content.search("<script") != -1) { content = "containes Javascript! />" + content.replace(/</g, "<"); } popup = new OpenLayers.Popup.FramedCloud ("test", feature.geometry.getBounds().getCenterLonLat(), new OpenLayers.Size(100,100), content, null, true, onPopupClose); feature.popup = popup; map.addPopup (popup); } <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <kml xmlns="http://earth.google.com/kml/2.1";> <Document> <name>Relation 1075685</name> <description></description> <Folder> <name>Segment 0<br></name> <visibility>true</visibility> <open>true</open> <description>Way IDs: 39028795, 39028794, ...</description> <Placemark> <Style> <LineStyle> <color>FF0000FF</color> <width>3.0</width> </LineStyle> </Style> <LineString> <coordinates>-1.6329761,48.1968307, ...</coordinates> </LineString> </Placemark> </Folder> </Document> </kml> _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
