},怎么修改
报错，优化流程，在父组件获取到原路线先绘制 this
.$refs
.mineMapRef
.update
RealtimeRoute
(dataPoints
);
this
.$refs
.mineMapRef
.addRouteMarker
(dataPoints[0], "end"
);
this
.$refs
.mineMapRef
.addRouteMarker
(dataPoints[dataPoints
.length - 1], "start"
);，在点击开始演习获取车辆实时位置handlestartTq，然后绘制新路线黄色，覆盖在原路线上，并且按照最新点位更新车辆图标
