问题描述
您好我有一个谷歌地图API的问题，我使用库绘图，不知道这是否正常，但是当我使用圆形绘图此刻开始画这个不出现在地图只在圆圈完成时出现，但其他控制器（如多边形或矩形）出现在开始绘制的瞬间，我没有复制谷歌地图API在其页面中具有的示例，并发生相同的情况。

推荐答案
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
});
希望它有帮助。
