<BODY style="MARGIN: 4px 4px 1px; FONT: 10pt Tahoma">
<DIV>I have a n OpenLayers map that displays point markers for a WFS layer served from Mapserver. The source data is an OGR Virtual layer reading froma table in a SQL-server database with x,y fields in a table.</DIV>
<DIV> </DIV>
<DIV>Here is the OL snippet that adds the layer:</DIV>
<DIV> </DIV>
<DIV>var wfs = new OpenLayers.Layer.WFS("API WFS", <BR> "<A href="http://10.65.192.1/cgi-bin/apiwfs.exe">http://10.65.192.1/cgi-bin/apiwfs.exe</A>?",<BR> {typename: 'apiaries_dev', maxfeatures: 100},<BR> {scales: [150000, 10], featureClass: OpenLayers.Feature.WFS});<BR> map.addLayers([wms1,wfs]);<BR> map.setBaseLayer(wms1);</DIV>
<DIV> </DIV>
<DIV>The layer displays fine on top of a base WMS layer.</DIV>
<DIV> </DIV>
<DIV>I want to be able to select a single marker using a CTRL-click, and send the attributes to a div below the map. Next I want to be able to capture a new location for the marker using ALT-click, and send the map coordinates to a separate div. From there, I will formulate a POST to a server to update the location in the source table.</DIV>
<DIV> </DIV>
<DIV>The code for capturing the coordinates is as follows:</DIV>
<DIV> </DIV>
<DIV>//add various map controls<BR> var control = new OpenLayers.Control();<BR> OpenLayers.Util.extend(control, {<BR> draw: function () {<BR> // this Handler.Point will intercept the ctrl-mousedown<BR> // before Control.MouseDefault gets to see it<BR> this.point = new OpenLayers.Handler.Point( control,<BR> {"done": this.notice},<BR> {keyMask: OpenLayers.Handler.MOD_ALT});<BR> this.point.activate();<BR> },</DIV>
<DIV> </DIV>
<DIV> notice: function (bounds) {<BR> document.getElementById('apiary').innerHTML = bounds;<BR> }<BR> });<BR> map.addControl(control);</DIV>
<DIV> </DIV>
<DIV>This works.</DIV>
<DIV> </DIV>
<DIV>However, I have no idea as to how to select and then get at the attributes of the WFS layer. Any help appreciated.</DIV>
<DIV> </DIV>
<DIV>Many thanks,</DIV>
<DIV> </DIV>
