[OpenLayers-Users] Re: How to apply a Search Function

[Diego M.]

*I keep trying to review my code bit it seems logic to me !
I have no idea why all features are loaded when I search for one !*

var strategy = new OpenLayers.Strategy.BBOX({ 
                            ratio: 1 // makes for easier comparison to map 
bounds 
                        });
var wfsprotocol = new OpenLayers.Protocol.WFS.v1_1_0({ 
                   url: "http://192.168.50.195:8080/geoserver/wfs";,

         });

     if (request.data && request.data.bbox) { 
           var b = request.data.bbox; 
           sExt = new OpenLayers.Bounds(b[0],b[1],b[2],b[3]); 
     }else { 
           var fts = request.features; 
           if (fts.length>0) { 
               sExt = fts[0].geometry.getBounds().clone(); 
               for(var i=1;i<fts.length;i++) { 
                  sExt.extend(fts[i].geometry.getBounds()); 
               }  } } 

     vessels.destroyFeatures();
