Question

我制作了一个谷歌地图，你可以使用绘图管理器绘制圆形/矩形，或使用自定义的“绘制圆形”和“绘制矩形”按钮，如下例所示 http://googlegeodevelopers.blogspot.com.au/2011/11/make-your-map-interactive-with-shape.html

然而在这个例子中，可以选择形状，然后在我的版本中删除，这是不可能的;所有形状总是被选中，我在文档中找不到任何东西？

我的代码：

<script type="text/javascript">
function drawCircle(){
        console.log("Drawing Circle on Map");
        var circleOptions = {
            <!--draw the circle in the center of the viewport-->
            center : (map.getCenter()),
            radius : 1000000,
            map: map,
            editable: true,
            clickable:true
        };

        circle = new google.maps.Circle(circleOptions);
        return false;
    }

    function drawRectangle(){
        console.log("Drawing Rectangle on Map");
        var rectOptions = {
            <!--draw the circle in the center of the viewport-->
            bounds: map.getBounds(),
            radius : 1000000,
            map: map,
            editable: true,
            clickable:true
        };

        rectangle = new google.maps.Rectangle(rectOptions);
        return false;
    }

    function showDrawingManager(){
        var managerOptions = {
            drawingControl: true,
            drawingControlOptions: {
            position: google.maps.ControlPosition.TOP_CENTER,
            drawingModes: [google.maps.drawing.OverlayType.MARKER, google.maps.drawing.OverlayType.CIRCLE,google.maps.drawing.OverlayType.RECTANGLE]
            },
            markerOptions: {
                editable: true
            },
            circleOptions: {
                editable: true
            },
            rectangleOptions: {
                editable : true
            }
        }

        var drawingManager = new google.maps.drawing.DrawingManager(managerOptions);
        drawingManager.setMap(map); 
    }
   </script>

我已回答了一个问题，其中绘制时的圆/多边形附有删除按钮（X标记）。单击它将删除它所附加的形状。
