Making sure KML layers display in order

kml-ordering.js

// Set the KML path
kml_path = "http://www.nhc.noaa.gov/storm_graphics/api/AL092011_019adv_"

// Load the KML files (must be publically available)
coneLayer = new google.maps.KmlLayer(
  kml_path + "CONE.kmz", 
    {preserveViewport: true}
  );

warningsLayer = new google.maps.KmlLayer(
  kml_path + "WW.kmz", 
    {preserveViewport: true}
  );

trackLayer = new google.maps.KmlLayer(
  kml_path + "TRACK.kmz", 
  {preserveViewport: true}
  );

// BEGIN SEQUENTIAL KML LOADING CODE
// This ensures the layers are drawn in order: cone, warnings, track

// Draw coneLayer
coneLayer.setMap(map);

// Listen for when coneLayer is drawn
var listener1 = google.maps.event.addListener(coneLayer, 'metadata_changed', function() {
  // When it's drawn (metadata changed), clear listener, draw warningsLayer ...
  google.maps.event.clearListeners(coneLayer, 'metadata_changed');
  warningsLayer.setMap(map);
  
  // .. and listen for when warningsLayer is drawn
  var listener2 = google.maps.event.addListener(warningsLayer, 'metadata_changed', function() {
    // When it's drawn, clear listener, draw trackLayer ...
    google.maps.event.clearListeners(warningsLayer, 'metadata_changed');
    trackLayer.setMap(map);
    
    // ... and listen for when trackLayer is drawn
    var listener3 = google.maps.event.addListener(trackLayer, 'metadata_changed', function() {
      // When it's drawn, clear listener and blank out the map-loading sign
      google.maps.event.clearListeners(trackLayer, 'metadata_changed');
      $('#loadingIndicator').html("");

    });
    
  });

});

// END SEQUENTIAL KML LOADING CODE

Great gist, thanks! :)

Rocks.

thanks!

Thanks!
