Hi, with OpenLayers.Control.WMSGetFeatureInfo is it
possible to restrict elements users can selected to only filtered
elements?
The standard openlayer code in geoserver, uses map.events.register to
select only filtered elements. In the OpenLayers API it was not clear
if this was possible for WMSGetFeatureInfo?
----
Standard code in geoserver
// support GetFeatureInfo
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(),
SERVICE: "WMS",
VERSION: "1.1.1",
X: e.xy.x,
Y: e.xy.y,
INFO_FORMAT: 'text/html',
QUERY_LAYERS: map.layers[0].params.LAYERS,
FEATURE_COUNT: 50,
Layers: 'HUNT:eiendom_flate',
WIDTH: map.size.w,
HEIGHT: map.size.h,
format: format,
styles: map.layers[0].params.STYLES,
srs: map.layers[0].params.SRS};
// merge filters
if(map.layers[0].params.CQL_FILTER != null) {
params.cql_filter = map.layers[0].params.CQL_FILTER;
}
if(map.layers[0].params.FILTER != null) {
params.filter = map.layers[0].params.FILTER;
}
if(map.layers[0].params.FEATUREID) {
params.featureid = map.layers[0].params.FEATUREID;
}
OpenLayers.loadURL("http://example.com/geoserver/wms";, params, this,
setHTML, setHTML);
OpenLayers.Event.stop(e);
});
simple example select example with WMSGetFeatureInfo
info = new OpenLayers.Control.WMSGetFeatureInfo({
url: 'http://something.com:8080/geoserver/wms',
title: 'Identify features by clicking',
layers: [tiled],
//hover:true,
queryVisible: true,
eventListeners: {
getfeatureinfo: function(event) {
map.addPopup(new OpenLayers.Popup.FramedCloud(
"chicken",
map.getLonLatFromPixel(event.xy),
null,
event.text,
null,
true
));
//alert(event.text);
}
}
});
