Not sure if this is correctly posted here or on the OpenLayers list but
I will try!
I am using OpenLayers, GeoServer 2.1.3. I have a function that works
to filter the markers on the map with a CQL_FILTER function. But when
I click on a marker it shows a popup with featureInfo information. If
there are hidden markers on the same coordinate (from the CQL_FILTER
function) every marker shows a popup, even if I have filtered them
out. Is it possible to only have the filtered markers give a popup?
The markers are on the same layer but I only want a popup to fire on
the filtered markers. Any advice to where I start would be be
appreciated!
function CQLfilter(sok,cat){
var mLayers = map.layers;
switch (cat)
{
case 'SN':
param = "scientificname LIKE '%"+ sok + "%' ";
break;
case 'NNG':
param = "norsknavngruppe LIKE '%"+ sok + "%' ";
break;
case 'NNA':
param = "norsknavnart LIKE '%"+ sok + "%' ";
break;
case 'PROJ':
param2 = new Array()
param2.push("prosjektnummer LIKE '%" + sok + "%'")
param2.push("prosjektnavn LIKE '%" + sok + "%'")
param = param2.join(" OR ");
break;
default:
param2 = new Array()
param2.push("scientificname LIKE '%" + sok + "%'")
param2.push("norsknavngruppe LIKE '%" + sok + "%'")
param2.push("norsknavnart LIKE '%" + sok + "%'")
param2.push("collector LIKE '%" + sok + "%'")
param = param2.join(" OR ");
break;
}
for(var a = 4; a < (mLayers.length); a++ ){
mLayers[a].mergeNewParams({'CQL_FILTER': param});
mLayers[a].setVisibility(true);
}}
Here is my code that generates the popup and the wmsGetFeatureInfo. I
guess it is here I must also do some kind of filtering on the wms
request but not sure how to do it:
info = new OpenLayers.Control.WMSGetFeatureInfo({
url: 'http://kart.naturkart.no/geoserver/wms',
title: 'Identify features by clicking',
queryVisible: true,
infoFormat:'application/vnd.ogc.gml',
eventListeners: {
getfeatureinfo: function(event) {
if (popup) {
map.removePopup(popup);
}
var contentHtml = '';
// Manage the features
if (event.features.length > 0) {
for (var i = 0; i < event.features.length; i++) {
var feature = event.features[i];
// Identify the type
if (feature.gml.featureType == 'ikke_rodlistet' ||
feature.gml.featureType ==
'kritisk_truet' ||
feature.gml.featureType == 'nar_truet' ||
feature.gml.featureType ==
'regionalt_utdodd' ||
feature.gml.featureType == 'saarbar' ||
feature.gml.featureType == 'sterkt_truet') {
// Create HTML content for this feature type
var locality = feature.attributes['locality'];
country = feature.attributes['country'];
scientificname =
feature.attributes['scientificname'];
kingdom = feature.attributes['kingdom'];
norsknavnart =
feature.attributes['norsknavnart']!= null?
feature.attributes['norsknavnart'] + ' | ':'';
norsknavngruppe =
feature.attributes['norsknavngruppe']!= null?
feature.attributes['norsknavngruppe'] + ' | ':'';
collector = feature.attributes['collector'];
kommentar =
feature.attributes['kommentar']!= null?
feature.attributes['kommentar'] + ' | ':'';
dateinterval =
feature.attributes['dateinterval'];
status = feature.attributes['status'];
statusimg = '<img src="/images/svg/bab_'+status+'.svg" width="10" />';
contentHtml = contentHtml + '<h2>' +
scientificname +' '+ statusimg + '</h2>';
contentHtml = contentHtml +
norsknavnart + norsknavngruppe + ' Reg.dato: ' + dateinterval + '<br
/>';
contentHtml = contentHtml + kommentar
+ ' Reg. av: ' + collector + '<br />';
contentHtml
= contentHtml + '<span class="popItem"><a
href="http://babkart.no/?x='+feature.attributes['x']+'&y='+feature.attributes['y']+'">Direkte
link</a> til dette artsfunn.</span><hr />';
}
}
} else {
// Don't show any popup if no features.
return; alert(map.getLonLatFromPixel(event.xy));
}
var popup = new Popup(
"chicken",
map.getLonLatFromPixel(event.xy),
null,
contentHtml,
null,
true
);
popup.autoSize = true;
map.addPopup(popup, true);
Ext.ux.Lightbox.register("a[rel^=lightbox]",true);
}
}
});
map.addControl(info);
info.activate();
