<DIV>Further to this, I have removed the featureClass parameter, and included extractAttributes: true:</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, extractAttributes: true},<BR> {scales: [150000, 10]});<BR> map.addLayers([wms1,wfs]);</DIV>
<DIV> </DIV>
<DIV>I have added:</DIV>
<DIV> </DIV>
<DIV>var options = {<BR> hover: true,<BR> onSelect: function(feature) { <BR> OpenLayers.Util.getElement('apiary').innerHTML = feature.attributes.apiary_id; <BR> }</DIV>
<DIV> </DIV>
<DIV> };<BR> var select = new OpenLayers.Control.SelectFeature(wfs, options);<BR> map.addControl(select);<BR> //select.handler.stopDown = false;<BR> //select.handler.stopUp = false;<BR> select.activate();</DIV>
<DIV> </DIV>
<DIV>This allows me to hover over each point and select it, however I am struggling to get at the attributes still. Here is a sample of the GML returned by Mapserver:</DIV>
<DIV> </DIV>
<DIV><BR> <gml:Point srsName="EPSG:2193"><BR><gml:coordinates>1824867.377072,5534693.953457</gml:coordinates><BR></gml:Point><BR></ms:msGeometry><BR><ms:apiary_id>88883</ms:apiary_id><BR><ms:x_nzmg>2734900</ms:x_nzmg><BR><ms:y_nzmg>6096500</ms:y_nzmg><BR><ms:beekeeper_reg_no>H0733</ms:beekeeper_reg_no><BR><ms:maf_id>7</ms:maf_id><BR></ms:apiaries_dev><BR></gml:featureMember><BR></wfs:FeatureCollection></DIV>
<DIV> </DIV>
<DIV>There are 5 attributes: apiary_id, x_nzmg, y_nzmg, beekeeper_reg_no, maf_id</DIV>
<DIV> </DIV>
<DIV>However, the onSelect function above returns "undefined" into the apiary div.</DIV>
<DIV> </DIV>
<DIV>How should I reference the attribute fields in each feature?</DIV>
<DIV> </DIV>
<DIV>Many thanks,</DIV>
<DIV> </DIV>

<DIV style="COLOR: #000000">
<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>
