AW: [mapserver-users] Query feature using openlayers and mapserver

[Arnd Wippermann]

Hi,

Look for the visibility of your "querylayer" and decide what to do

map.events.register('click', map, function (e) 
{
    var flag=map.getLayersBy("name", "querylayer")[0].visibility;

    if(flag)
    {
        var url = "http://localhost/cgi-bin/mapserv.exe"
          + "?map=map/file/directory.map" 
          + "&REQUEST=GetFeatureInfo"
          + "&VERSION=1.1.1"
          + "&EXCEPTIONS=application/vnd.ogc.se_xml"
          + "&BBOX=" 
          + map.getExtent().toBBOX()
          + "&X=" + e.xy.x
          + "&Y=" + e.xy.y
          + "&INFO_FORMAT=text/html"
          + "&QUERY_LAYERS=querylayer"
          + "&LAYERS=querylayer"
          + "&FEATURE_COUNT=1"
          + "&SRS=EPSG:4269"
          + "&STYLES="
          + "&WIDTH=" + map.size.w
          + "&HEIGHT=" + map.size.h;
        window.open(url, "getfeatureinfo",
"location=0,status=0,scrollbars=1,width=600,height=400");
    }
});     

Regards,
Arnd

I have solved the problem. There is the function code in my html:
 map.events.register('click', map, function (e) {
    var url = "http://localhost/cgi-bin/mapserv.exe"
      + "?map=map/file/directory.map" 
      + "&REQUEST=GetFeatureInfo"
      + "&VERSION=1.1.1"
      + "&EXCEPTIONS=application/vnd.ogc.se_xml"
      + "&BBOX=" 
      + map.getExtent().toBBOX()
      + "&X=" + e.xy.x
      + "&Y=" + e.xy.y
      + "&INFO_FORMAT=text/html"
      + "&QUERY_LAYERS=querylayer"
      + "&LAYERS=querylayer"
      + "&FEATURE_COUNT=1"
      + "&SRS=EPSG:4269"
      + "&STYLES="
      + "&WIDTH=" + map.size.w
      + "&HEIGHT=" + map.size.h;
    window.open(url,
      "getfeatureinfo",
      "location=0,status=0,scrollbars=1,width=600,height=400"
    );

But if I turn off the layer, I click on the map, a new window still come
out. That is not the problem. The problem is the turned off layer can still
be queried. I want that the turned off layer is not queryable. 
New window can still come out without any information. Please give me a
hand.


Thanks,
Aypes
