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.
Here is the OL snippet that adds the layer:
var wfs = new OpenLayers.Layer.WFS("API WFS",
"http://10.65.192.1/cgi-bin/apiwfs.exe?";,
{typename: 'apiaries_dev', maxfeatures: 100},
{scales: [150000, 10], featureClass: OpenLayers.Feature.WFS});
map.addLayers([wms1,wfs]);
map.setBaseLayer(wms1);
The layer displays fine on top of a base WMS layer.
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.
The code for capturing the coordinates is as follows:
//add various map controls
var control = new OpenLayers.Control();
OpenLayers.Util.extend(control, {
draw: function () {
// this Handler.Point will intercept the ctrl-mousedown
// before Control.MouseDefault gets to see it
this.point = new OpenLayers.Handler.Point( control,
{"done": this.notice},
{keyMask: OpenLayers.Handler.MOD_ALT});
this.point.activate();
},
notice: function (bounds) {
document.getElementById('apiary').innerHTML = bounds;
}
});
map.addControl(control);
This works.
However, I have no idea as to how to select and then get at the attributes of
the WFS layer. Any help appreciated.
Many thanks,
Robert Sanson
