hello !
My problem is that i can't draw a circle on my map with the following
code
I m really newbie using google map and js so please be indulgent ^^
the map is well displayed but no circle ...
this is the whole code :
the code is include in a php string so you will see $map which is an
array containing some information about what to display
$map['lat'] and $map['lon'] are coordinates of the center of the
wished circle
$map[radius] the radius...
<script type=\"text/javascript\">
var map;
function initialize() {
if (GBrowserIsCompatible()) {
map = new
GMap2(document.getElementById(\"map_canvas\"));
map.setCenter(new GLatLng(".$map['lat'].",
".$map['lon']."),".
$map['zoom'].");
map.setUIToDefault();
drawCircle();
}
}
function drawCircle(){
var centerPoint = new GLatLng(".$map['lat'].",".
$map['lon'].");
var circlePoints = Array();
with (Math) {
var radius = ".$map['radius'].";
for (var a = 0 ; a < 361 ; a+=10 ) {
var aRad = a*(PI/180);
y = ".$map['lat']." + radius * sin(aRad)
x = ".$map['lon']." + radius * cos(aRad)
circlePoints.push(new GLatLng(x,y));
}
map.removeOverlay(circleLine);
circleLine = new GPolyline(circlePoints,'#FD942D',1,
5);
map.addOverlay(circleLine);
}
}
</script>
(i can't give you the link of the map because it's only in local for
the moment)
