Dear All,
I run OpenLayers on Geoserver and I have some features which i would like the
user to click on and get information, say GetFeatureInfo. I have tried a few
help but they don't seem to help me (see the code below) - I only see a blank
space, no result. I am new to these things, don't know what is wrong but I
need
to get something done here. Can somebody please tell me what is wrong? I work
on
my university server but Geoserver is installed on my local machine, not over
the server. Does that have anything to do with my result.
Somebody please help. The result can be wrapped in a popup textbox or somewhere
on the map window. A step-by-step guide will be very much appreciated because i
don't even know if i need to add something before this code or after it. Thanks
a million!!
//Code used to support GetFeatureInfo request
map.events.register('click', map, function (e) {
document.getElementById('nodelist').innerHTML = "Loading...
please wait...";
var params = {
REQUEST: "GetFeatureInfo",
EXCEPTIONS: "application/vnd.ogc.se_xml",
BBOX: map.getExtent().toBBOX(),
X: e.xy.x,
Y: e.xy.y,
INFO_FORMAT: 'text/html',
QUERY_LAYERS: map.layers[0].params.LAYERS,
FEATURE_COUNT: 50,
Layers: 'thesis:SLChiefdoms_adm3',
Styles: '',
Srs: 'EPSG:32628',
WIDTH: map.size.w,
HEIGHT: map.size.h,
format: format};
OpenLayers.loadURL("http://localhost:8090/geoserver/wms";,
params, this, setHTML, setHTML);
OpenLayers.Event.stop(e);
});
}
// sets the HTML provided into the nodelist element
function setHTML(response){
document.getElementById('nodelist').innerHTML =
response.responseText;
};
