Html 移动多段线/多边形顶点时获取更新坐标。（谷歌地图）

我已经知道如何在添加多段线或多边形或删除顶点时捕捉坐标，但似乎无法应用如何在移动多段线或多边形顶点时捕捉坐标（仅限顶点，我已故意禁用拖动整个多边形）。我将此链接用作参考：

以下是我的完整HTML代码（为了方便读者，在pastebin发布）：

以下是我试图做出接球动作的部分：

google.maps.event.addListener(drawingManager, 'overlaycomplete', function(e) {

  var newShape = e.overlay;
  newShape.type = e.type;

  if (e.type !== google.maps.drawing.OverlayType.MARKER) {
    // Switch back to non-drawing mode after drawing a shape.
    drawingManager.setDrawingMode(null);

    ///////////////////////////////////////////////////////////

        google.maps.event.addListener(newShape.getPath(), 'insert_at', function(e) {
          var path = newShape.getPaths().getAt(e.path);
          document.getElementById("polygonEditTest").value += path.getAt(e.vertex) + '\n';

编辑：我认为这是演示问题所需的最少代码（无法捕获顶点移动）
