[OpenLayers-Users] WFS Layers, Markers, Popups

[Lehtonen, Mika]

Hi Indika,

maybe you can get something out of this code of mine. I can explain it 
better later on when I have better time. BTW: hiiri is a mouse in 
Finnish ;-)

cheers,
mika

	map.events.register('click', null, function (e) {
       OpenLayers.Util.getElement('nodelist').innerHTML = "Odota hetki...";
		var hiiri = wfs.map.getLonLatFromPixel(e.xy);
var hiirixy = (hiiri.lat+','+hiiri.lon);

		var url =  wfs.getFullRequestString({
				SERVICE: 'WFS',
				VERSION: '1.1.0',
				REQUEST: 'GetFeature',
				OUTPUTFORMAT: 'json',
				PROPERTYNAME: 'the_geom,LAYER',
				MAXFEATURES: 5,
				TYPENAME: 'dikanet:karsa_region',
				SRSNAME: 'EPSG:2393',
				FILTER: '<wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs" xmlns:ogc="http://www.opengis.net/ogc" service="WFS" version="1.1.0" xmlns:gml="http://www.opengis.net/gml"><gml:featureMember><ogc:Filter><ogc:Contains><ogc:PropertyName>the_geom</ogc:PropertyName><gml:Point><gml:coordinates>'+hiirixy+'</gml:coordinates></gml:Point></ogc:Contains></ogc:Filter></gml:featureMember></wfs:FeatureCollection>'
},
                           "http://karsamaki.digikartta.net/asemakaavat/wfs"
                           );
