Right Nathan.
Or, if anyone likes to save the current polygon as it gets created, instead
of saving all polygon coordinates using a loop. You might also use the below
technique.
polycontrol = new OpenLayers.Control.DrawFeature(vectors,
OpenLayers.Handler.Polygon, {'featureAdded': setPolygonLocation});
map.addControl(polycontrol);
polycontrol.activate();
and, on completion of polygon draw. setPolygonLocation is fired with an
object
function setPolygonLocation(obj){
var points = obj.geometry.toString();
document.getElementById("polygon_location").value=points; //
Save this point
polycontrol.deactivate();
}
Thanks,

Subject: Re: [OpenLayers-Users] How do I get my polygon coordinates?
I use a different method for getting the polygons as a text string, keep in
mind this is for catching all polygons in the given layer and not for a
selected or recently drawn polygon.
//put in your map init() function
wkt = new OpenLayers.Format.WKT();
//Put this where you desire it to be and modify as necessary
for (var i=0;i<vectors.features.length;i++) {
//if (selFeatureID == vectors.features[i].id) {}
var str = wkt.write(vectors.features[i]);
ajaxSendParams += "&bdySegment="+escape(str);
}

Hey GeoUser,
Instead of using getComponentsString(), I use toString()... and, I get the
result... but the format is different. Might have to do some string
manipulation... However, this is good to go for now...
Thanks man!!
