The following javascript snippet is supposed to do the following:
As the user clicks on the map, initialize headMarker and draw a circle (polygon) around it
As the user clicks inside the circle, initialize tailMarker and draw the path between these two markers
1 is happening as expected. But as the user clicks inside the circle, overlay is non-null while point is null in the function(overlay,point) . Can someone tell me a way out.
GEvent.addListener(map, "click", function(overlay,point) {
if (isCreateHeadPoint) {
// add the head marker
headMarker = new GMarker(point,{icon:redIcon,title:'0'});
map.addOverlay(headMarker);
isCreateHeadPoint = false;
// draw the circle
drawMapCircle(point.lat(),point.lng(),1,'#cc0000',2,0.8,'#0',0.1);
} else {
// add the tail marker
tailMarker = new GMarker(point,{icon:greenIcon,title:''});
map.addOverlay(tailMarker);
isCreateHeadPoint = true;
// load thes path from head to tail
direction.load("from:" + headMarker.getPoint().lat()+ ", " + headMarker.getPoint().lng()+ " to:" + tailMarker.getPoint().lat() + "," + tailMarker.getPoint().lng(), {getPolyline:true});
}
});
