Google map Uncaught RangeError: Maximum call stack size exceeded main.js.27

Question

我有一张 google 地图，我可以在其中绘制多边形。它一直运行良好，现在突然出现错误 Uncaught RangeError: Maximum call stack size exceeded main.js.27。下面是我的初始化函数的一部分，当我完成绘制多边形时，我在加载 map.Now 时调用了这个错误。

    function clearSelection() {
        for (var n = 0; n<shapes.length; n++) {
            var shapesOne = shapes[n];
            shapesOne.setMap(null);
        }
    }

    function setSelection(shape) {
        selectedShape = shape;
        shape.setEditable(true);
        selectColor(shape.get('fillColor') || shape.get('strokeColor'));
    }

    function deleteSelectedShape() {
        if (selectedShape) {
            selectedShape.setMap(null);
        }
    }

    function selectColor(color) {
        selectedColor = color;
        var polylineOptions = drawingManager.get('polylineOptions');
        polylineOptions.strokeColor = color;
        drawingManager.set('polylineOptions', polylineOptions);

        var rectangleOptions = drawingManager.get('rectangleOptions');
        rectangleOptions.fillColor = color;
        drawingManager.set('rectangleOptions', rectangleOptions);

        var circleOptions = drawingManager.get('circleOptions');
        circleOptions.fillColor = color;
        drawingManager.set('circleOptions', circleOptions);

        var polygonOptions = drawingManager.get('polygonOptions');
        polygonOptions.fillColor = color;
        drawingManager.set('polygonOptions', polygonOptions);
    }

    function setSelectedShapeColor(color) {
        if (selectedShape) {
            if (selectedShape.type == google.maps.drawing.OverlayType.POLYLINE) {
                selectedShape.set('strokeColor', color);
            } else {
                selectedShape.set('fillColor', color);
            }
        }
     }

     function makeColorButton(color) {
         var button = document.createElement('span');
         button.className = 'color-button';
         button.style.backgroundColor = color;
         google.maps.event.addDomListener(button, 'click', function(){
              selectColor(color);
              setSelectedShapeColor(color);
         });

         return button;

其他人发布了类似的问题，他们建议：

if (drawManager.getDrawingMode()) {
  drawManager.setDrawingMode(null);
}
