How can a polygon be highlighted (or filled with a different color , than
other polygon) which is returened by the WFS search result. Eg. Topp.states
: when I put Texas in the textbox and click on Search Button , the map
zooms to that texas state area with WFS . That is working fine. I also want
this texas polygon to be highlighted. How can it be done.
I tried using json format , but it didn't visualize the output.
The code on the search button is :
function searchFunction(searchkey)
{
document.getElementById("point").style.display = 'none';
if (searchkey == "A")
{
fullExtent();
}
if (xmlhttp !=null)
{
xmlhttp.abort();
xmlhttp = null;
}
clearPopupTimer();
URL = "http://"+SERVERHOSTNAME+"/geoserver/wfs/GetFeature";;
XML = '<?xml version="1.0" encoding="UTF-8"?>'+"\n";
XML += '<wfs:GetFeature service="WFS" version="1.0.0"'+"\n";
XML += ' outputformat="json"'+"\n";
XML += ' xmlns:tiger="http://www.openplans.org/tiger";'+"\n";
XML += ' xmlns:wfs="http://www.opengis.net/wfs";'+"\n";
XML += ' xmlns:ogc="http://www.opengis.net/ogc";'+"\n";
XML += ' xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";'+"\n";
XML += ' xmlns:gml="http://www.opengis.net/gml";>'+"\n";
XML += ' '+"\n";
XML += ' <Query typeName="topp:states">'+"\n";
XML += ' <ogc:Filter>'+"\n";
XML += ' <ogc:PropertyIsEqualTo>'+"\n";
XML += ' <ogc:PropertyName>STATE_NAME</ogc:PropertyName>'+"\n";
XML += ' <ogc:Literal>'+searchkey+'</ogc:Literal>'+"\n";
XML += ' </ogc:PropertyIsEqualTo>'+"\n";
XML += ' </ogc:Filter>'+"\n";
XML += ' '+"\n";
XML += ' </Query>'+"\n";
XML += '</wfs:GetFeature>'+"\n";
getXML(URL,XML,XMLProgressSearchFunction);
}
I tried with( XML += ' outputformat="json"'+"\n";) all format .
Is it possible to use openlayer to achieve this.
Thanks,
