Toggle KML Layers in Google Maps v3

Question

Is there a simple way to set up checkboxes to toggle (on/off) KML layers for Google Maps v3? I\'ve come across these articles, but none of them have worked for me.

Answer 1

For toggling kml layer you can try this function:

/** Toggles layer
* @param {google.maps.KmlLayer} layer
* @param {google.maps.Map} map
**/ 
function toggleLayer( layer, map ){
     layer.setMap( layer.getMap() ? null : map );
}

Store your layers in array for farther actions (e.g. toggling).

Then you can toggle layer by it's index on that array:

toggleLayer( layersArray[index], map );

Or to apply toggling to all layers:

for( var index = 0; index < layersArray.length; ++index){
    toggleLayer( layersArray[index], map );
}
