Yes. But perhaps your attributes have to be like ... <feature:type>0</feature:type> <feature:name>Type 0</feature:name> <feature:description>Feature Type</feature:description> ... So that OL is able to parse them. Arnd -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Hans Gregers Petersen Gesendet: Mittwoch, 22.

I use Geoserver to serv features to Openlayers (via WFS) and the points are added to the map as they are supposed to. My problem is getting the attribute dato from each feature, I can extract feature.fid, which is correct, but nothing is available from feature.attributes. Should it not be possible to extract attributes from the feature, when the WFS constructor is given the "extractAttributes:true" option? I have googled and googled (there does not seem to be more than a number of people using WFS + attributes?), and tried a number of things so any help or hints would be great. Best Regards, Gregers Petersen A sample of the returned GML is: <gml:featureMember> <paspunkter:punkter fid="punkter.1"> <paspunkter:x>43.4</paspunkter:x> <paspunkter:y>47.12</paspunkter:y> <paspunkter:z>23.1</paspunkter:z> <paspunkter:kvalitetplan>1.2</paspunkter:kvalitetplan> <paspunkter:latlon> <gml:Point srsName="http://www.opengis.net/gml/srs/epsg.xml#900913";> <gml:coordinates decimal="." cs="," ts=" ">1322846.5784869,7360249.01559515</gml:coordinates> </gml:Point> </paspunkter:latlon> </paspunkter:punkter> </gml:featureMember> The relevant parts of my JavaScript code is: function onFeatureSelect(feature) { selectedFeature = feature; var streng = "<div style='font-size:.8em'>Feature: " + feature.fid + "<br/>Attributes:"; for(var i in feature.attributes) streng += "<br/><b>" + i + "</b>: "+ feature.attributes[i]; streng += "</div>" popup = new OpenLayers.Popup.FramedCloud("GlibGlab", feature.geometry.getBounds().getCenterLonLat(), null, streng, null, true, onPopupClose); feature.popup = popup; map.addPopup(popup); } /* snip */ function init(){ var options = { projection: new OpenLayers.Projection("EPSG:900913"), units: "m", maxResolution: 156543.0339, maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34, 20037508.34, 20037508.34) }; map = new OpenLayers.Map( 'map', options ); // Google Satellite var googleSatLayer = new OpenLayers.Layer.Google("Google Satellite",{type: G_SATELLITE_MAP, sphericalMercator:true, numZoomLevels: 21 }); map.addLayer(googleSatLayer); /* snip */ // Our paspunkt layer var ppLayer = new OpenLayers.Layer.WFS( "Paspunkter", "WFSproxy.ashx?", {typename: "paspunkter:punkter", extractAttributes:true, displayInLayerSwitcher:false}); map.addLayer(ppLayer); /* snip */ } _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
