Hello to everyone,
In the map I'm working on, I would like to activate a kml layer when
pressing a custom control. The layer then is displayed onto the map.
I also would like to show kml metadata description inside a page
element. The problem is that, when I clik on the control to show the
kml layer, metadata is still undefined. But next time I click,
metadata is well defined.
Some pseudocode to show the problem:
var
metadata; //
define somewhere above
// Custom control listener
google.maps.event.addDomListener(controlUI, 'click', function() {
if (TourLayer.getMap() == null)
{ // if layer is not displayed
TourLayer.setMap(map); //
display map
controlText.innerHTML = 'Tour ON';
metadata = TourLayer.getMetadata (); //
metadata is undefined on the first call
showInDiv (metadata.name, metadata.description);
}
else {
TourLayer.setMap();
controlText.innerHTML = 'Visita OFF';
}
});
Is there a way to get kml layer metadata before the layer is showed in
the map for the first time?
I am doing something wrong?
Thanks for your help.
