using the eventlistener on just one layer

[Jonathan Gamble]

I'm trying to create a balloon from from information on just one kml
layer while the other layers are shown...

// the add and remove kml functions

function addObject(object) {
ge.getFeatures().appendChild(object);
}
function removeObject (object) {
ge.getFeatures().removeChild(object);
}

// define the kml objects

var red, wells, green, yellow;

// fetch the KML
var url = 'yellow.kml';
google.earth.fetchKml(ge, url, function(kmlObject) {
yellow = kmlObject;
addObject(kmlObject);
});

// fetch the KML
var url = red.kml';
google.earth.fetchKml(ge, url, function(kmlObject) {
red = kmlObject;
addObject(kmlObject);
});

// fetch the KML
var url = 'wells.kml';
google.earth.fetchKml(ge, url, function(kmlObject) {
wells = kmlObject;
addObject(kmlObject);
});

// fetch the KML
var url = 'green.kml';
google.earth.fetchKml(ge, url, function(kmlObject) {
green = kmlObject;
addObject(kmlObject);
});

google.earth.addEventListener(ge.getGlobe(), 'click', function
(event) {


removeObject(green);
removeObject(yellow);
removeObject(wells);


// prevent the default balloon from popping up
event.preventDefault();

var KMLData;

if (event.getTarget().getType() == 'KmlPlacemark') {

KMLData = event.getTarget().getName();

// create the balloon
var balloon = ge.createHtmlStringBalloon('');

balloon.setFeature(event.getTarget());
balloon.setMaxWidth(450);

// print the balloon
balloon.setContentString(KMLData);

ge.setBalloon(balloon);

}

addObject(green);
addObject(yellow);
addObject(wells);

});

});

}

The problem is that the code still gets data from all 4 layers
depending on where you click. Is it possible to just get information
(the getName() function) from just one layer regardless of whether or
not the other layers are visible?

Thanks,
