vue编写动态绘制只能绘制一次，点击其他图形绘制报错

[18465139686]

第一次点击一个图形可以进行绘制，但是当你第二次点击其他图形绘制时就会报错？？？

一、当第二次点击其他图形绘制时，就会报以下错：
VM32937:1 Uncaught ReferenceError: RuntimeError is not defined at Tl.add (eval at <anonymous> (Cesium.js:1), <anonymous>:1:3881794) at Plotting.InitPlot (plotting.js?159d:26) at new Plotting (plotting.js?159d:15) at o.imageClick (index.vue?0dbc:234) at click (index.vue?f684:31) at i (vue.min.js:6) at HTMLImageElement.Rr.t._withTask.o._withTask (vue.min.js:6)
二、这是vue页面调用plotting.js文件实现的：
method:{ // 绘制面板 imageClick(val) { var plotting = new Plotting(window.viewer); if (plotting) { plotting.DrawCellClick(val); } }, }

三、这是我提取出来的文件和开源集成的：
`class Plotting {
constructor(viewer) {
this.viewer = viewer;
this.host = 'http://support.supermap.com.cn:8090';
this.cesium = Cesium;
this.scene = viewer.scene;
this.scene.globe.depthTestAgainstTerrain = false;
this.serverUrl = this.host + '/iserver/services/plot-jingyong/rest/plot';
this.plotting;
this.plottingLayer;
this.plotEditControl;
this.plotDrawControl;
this.plotPanel;
this.stylePanel;
this.InitPlot();
}
InitPlot() {
var self = this;
if (!this.viewer) {
return;
}
self.plottingLayer = new self.cesium.PlottingLayer(
self.scene,
'plottingLayer',
);
self.scene.plotLayers.add(self.plottingLayer);

self.plotEditControl = new self.cesium.PlotEditControl(
  self.scene,
  self.plottingLayer,
); //编辑控件
self.plotDrawControl = new self.cesium.PlotDrawControl(
  self.scene,
  self.plottingLayer,
); //绘制控件 

self.plotDrawControl.drawControlEndEvent.addEventListener(()=>{
  //标绘结束，激活编辑控件

  self.plotEditControl.activate();
});

self.plotting = self.cesium.Plotting.getInstance(
  self.serverUrl,
  self.scene,
);
//标绘面板
// initPlotPanel("plotPanel", serverUrl, plotDrawControl, plotEditControl, plotting);
// 属性面板
// self.stylePanel = new StylePanel(
//   'stylePanel',
//   self.plotEditControl,
//   self.plotting,
// );

}
DrawCellClick(drawCellparam) {
console.log(drawCellparam,'drawcell');
console.log(this.plotDrawControl,'plotDraw');
var self = this;
if (self.plotDrawControl !== null) {
self.plotDrawControl.deactivate();
self.plotDrawControl.libID = drawCellparam.libID;
self.plotDrawControl.code = drawCellparam.symbolCode;

  //设置标号默认的模型路径
  self.plotDrawControl.drawFinishEvent.addEventListener(function (geo) {
    if (geo.symbolType === SuperMap.Plot.SymbolType.DOTSYMBOL) {
      geo.modelPath = './SampleData/plot/Cesium_Air.gltf';
      geo.picturePath = './SampleData/plot/blupin.png';
    }
  });
  self.plotDrawControl.serverUrl = self.serverUrl;

  self.plotDrawControl.activate();
  if (undefined !== self.plotEditControl) {
    self.plotEditControl.deactivate();
  }
}

}
//删除指定标号
deleteSeleGeo() {
var self = this;
self.plottingLayer.removeGeoGraphicObject(
self.plottingLayer.selectedFeature,
);
}
//获取属性面板GridDom
getGridDomObdect() {
var self = this;
return self.stylePanel.getDomObject();
}

// // 想要通过该方法来暴露x
// showX () {
// return this.x
// }
}
export default Plotting;
