I think I got it!
var layersToBeQueried = [layerA, layerB, layerC, layerD, layerE];
function removeLayersOutOfRange(layerArray){
var retArray = new Array();
for(var i = 0; i < layerArray.length; i++) {
//alert(layerArray[i].name);
if(layerArray[i].calculateInRange() == true){
retArray.push(layerArray[i]);
}
}
return retArray;
}
var info = new OpenLayers.Control.WMSGetFeatureInfo({
url: layerURL,
layerUrls: [layerURL],
title: 'Identify features by clicking',
// layers: removeLayersOutOfRange(layersToBeQueried),
queryVisible: true,
eventListeners: {
beforegetfeatureinfo: function(event) {
this.layers =
removeLayersOutOfRange(layersToBeQueried);
},
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();
Changing the removeLayersOutOfRange() function a bit, in my previous post I
was looping through my array improperly because splice() was resizing it on
the fly. Not specifying the layers in the config options but waiting to
specify them in the beforegetfeatureinfo event handler allows for a new set
of layers to be subjected for querying upon each different request.
Hope this helps someone and happy mapping,
