I'm trying to draw a circle in google map v2 for my project and use it
with google local search. But the map just doesn't show the circle.
the code below is my code... Please help me...
________________________________________________________________________
google.load('maps', '2.115');
var map;
var circle;
function OnLoad() {
map = new google.maps.Map2(document.getElementById("Map"));
map.addControl(new google.maps.MapTypeControl()); // Add the map
type control
map.setMapType(G_HYBRID_MAP);
map.enableContinuousZoom();
map.enableScrollWheelZoom();
map.setCenter(new google.maps.LatLng(3.058068, 101.688166), 15);
var center = map.getCenter();
circleRadius = 1;
var circlePoints = Array();
var d = circleRadius/6378.8; // radians
var lat1 = (PI/180)* center.lat(); // radians
var lng1 = (PI/180)* center.lng(); // radians
for (var a = 0 ; a < 361 ; a++ ) {
var tc = (PI/180)*a;
var y = asin(sin(lat1)*cos(d)+cos(lat1)*sin(d)*cos(tc));
var dlng = atan2(sin(tc)*sin(d)*cos(lat1),cos(d)-
sin(lat1)*sin(y));
var x = ((lng1-dlng+PI) % (2*PI)) - PI ; // MOD function
var point = new GLatLng(parseFloat(y*(180/PI)),parseFloat(x*(180/
PI)));
circlePoints.push(point);
}
circle = new GPolygon(circlePoints, '#6699FF', 1, 1, '#CCCCFF',
0.25);
map.addOverlay(circle);
}
google.setOnLoadCallback(OnLoad);
