Hi.
Here's abit of code i've used before to do this:
// myPolyline is your polyline
// mousePosition is the mouse position as a GLatLng
var length=myPolyline.getVertexCount(), distance, nearestDistance,
nearestIndex;
for(i=0; i<length; i++){
distance=myPolyline.getVertex(i).distanceFrom(mousePosition);
if(i===0){
nearestDistance=distance;
nearestIndex=i;
} else if(nearestDistance>distance){
nearestDistance=distance;
nearestIndex=i;
}
}
So the nearest polyline vertex to the mouse position is
myPolyline.getVertex(nearestIndex), and the distance betwen nearest
vertex and mouse position is nearestDistance.
