Question

请您查看This Demo并告诉我如何在完成第一个对象的绘制时强制Google地图进入绘图模式！

正如您在演示中所看到的，绘图模式保持每种选定的类型，直到用户点击“停止绘图”控件，但我需要将其更新为自动检测到的格式。

这是我的代码：

  map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    var drawingStyle = {
        strokeWeight: 0,
        fillOpacity: 0.45,
        editable: true,
        draggable: true
    };
    var drawingManager = new google.maps.drawing.DrawingManager({

        drawingControl: true,
        drawingControlOptions: {
            position: google.maps.ControlPosition.TOP_CENTER,
            drawingModes: [
            google.maps.drawing.OverlayType.CIRCLE,
            google.maps.drawing.OverlayType.POLYGON,
            google.maps.drawing.OverlayType.RECTANGLE]
        },
        rectangleOptions: drawingStyle,
        polygonOptions: drawingStyle,
        circleOptions: drawingStyle
    });
    drawingManager.setMap(map);

谢谢，

文档说明这些事件存在于DrawingManager中：

circlecomplete |圈|用户完成绘制圆圈后会触发此事件。
markercomplete |标记|用户完成绘制标记后会触发此事件。
overlaycomplete | OverlayCompleteEvent |当用户完成绘制任何类型的叠加层时，将触发此事件。
polygoncomplete |多边形|用户完成绘制多边形时会触发此事件。
polylinecomplete |折线|用户完成绘制折线后会触发此事件。
rectanglecomplete |矩形|当用户完成绘制矩形时会触发此事件。

如果你想在它们发生时做某事，为它们添加一个监听器：

google.maps.event.addListener(drawingManager,'overlaycomplete',function() {
    drawingManager.setOptions({drawingMode: null, drawingControl: false});
});
