[OpenLayers-Users] Best strategy to add many clickable rectangle areas?

[darrepac]

Hi Arnd,

Thanks for your help.
I have setup correctly 2 rectangle areas within a GML file but I cannot make
it work. Questions:
- where do I put the attribute with the name in the GML?? Here is an extract
of my gML:

<gml:featureMember>
    <attribute name="http://www.google.com" />
      <ms:polygon fid="1">
        <gml:polygonMember>
          <gml:Polygon srsName="EPSG:4326">
            <gml:outerBoundaryIs>
              <gml:LinearRing>
                <gml:coordinates>2.71113144,41.73139136
2.39768263,41.73139136 2.39768263,41.55005677 2.71113144,41.55005677
2.71113144,41.73139136 </gml:coordinates>
              </gml:LinearRing>
            </gml:outerBoundaryIs>
            
          </gml:Polygon>
        </gml:polygonMember>
        <ms:ogc_fid>1</ms:ogc_fid>
        <ms:name>http://www.yahoo.com</ms:name>
        <ms:id>0</ms:id>
      </ms:polygon>
    </gml:featureMember> 

- I presume that your function has to be put outside the initial load
function?


Thanks!
