Question

嗨我有一个谷歌地图api的问题，我使用图书馆绘图，不知道这是否正常，但当我正在使用圆形绘图时，开始画这个不会出现在地图仅在圆圈完成时出现，但另一个控制器如多边形或矩形它出现在开始绘制的瞬间，我确实复制了谷歌地图api在他们的页面中的示例并且发生了同样的事情..

一些解决方案..感谢您的帮助。

这是Google maps API的代码

加载地图后尝试使用此代码。它为我工作。

var rad=9;
var draw_circle=null;
draw_circle = new google.maps.Circle({
                                     center: new google.maps.LatLng(32.0833, 34.8000),
                                     radius: rad,
                                     strokeColor: "#FFFFFF",
                                     strokeOpacity: 0.8,
                                     strokeWeight: 2,
                                     fillColor: "#FFFFFF",
                                     fillOpacity: 0.35,
                                     map: map
                                     });

希望它有所帮助。！
