So I received another response from Dietmar, many thanks btw :)
I sorta used ideas from this and came up with my own little thing...
However, it isn't exactly working as expected :(
The problem is a function I wrote removeLayersOutOfRange() is called before
the getfeatureinfo: function(event) but if I move it to the getfeatureinfo:
function(event), it also has no effect...
I need a way for my function removeLayersOutOfRange() to check on each and
every call to getfeatureinfo: function(event) and tell it which layers are
not wanted for getfeatureinfo...
var layersToBeQueried = [layerA, layerB, layerC, layerD, layerE];
function removeLayersOutOfRange(layerArray){
for(var i = 0; i < layerArray.length; i++) {
alert(layerArray[i].name);
if(layerArray[i].calculateInRange() == false){
layerArray.splice(i,1);
}
}
return layerArray;
}
var info = new OpenLayers.Control.WMSGetFeatureInfo({
url: layerURL,
layerUrls: [layerURL],
title: 'Identify features by clicking',
layers: removeLayersOutOfRange(layersToBeQueried),
queryVisible: true,
eventListeners: {
getfeatureinfo: function(event){
if(event.text.length <= 687){}else{
popup = new GeoExt.Popup({
title: "Popup",
location: event.xy,
autoScroll: true,
height: $('#myViewPort').height() -
250,
maximizable: true,
collapsible: true,
map: mapPanel.map,
anchored: true,
html: '<div id="popupWrap"></div>',
listeners: {
close: function() {
// closing a popup destroys it,
but our reference is truthy
popup = null;
}
}
});
popup.show();
}//end if
}//end getfeatureinfo
}//end eventListeners
});//end OpenLayers.Control.WMSGetFeatureInfo
mapPanel.map.addControl(info);
info.activate();
All your kind suggestions are greatly appreciated :)
Thank you,
elshae
