Mapbox通过容器ID获取源/图层

Question

我使用Mapbox GL在地图上显示数据，容器如下所示：

def check_progress(self):
    if self.done:
        # calculation done, update graph
        self.a.clear() 
        self.a.bar(self.xAxis, self.yAxis)
        self.canvas.draw()
        # show the graph
        self.tkraise()
    else:
        # calculation not done, schedule next check
        self.after(500, self.check_progress)

def real_Graph(self):
    self.done = False # set calculation not done
    time.sleep(5)
    x1 = float(self.controller.shared_data["x1"].get())
    x2 = float(self.controller.shared_data["x2"].get())
    x3 = float(self.controller.shared_data["x3"].get())
    self.xAxis = [float(x1),float(x2),float(x3)]
    self.yAxis = [float(x1),float(x2),float(x3)]
    self.done = True # set calculation done

def Graph(self):
    self.controller.show_frame(WaitingPage)
    # create other thread to do calculation
    threadGraph = threading.Thread(target=self.real_Graph)
    threadGraph.start()
    # start the progress check
    self.check_progress()

初始化是通过以下代码完成的：

<div id="map" class="mapboxgl-map">

是否存在仅使用元素ID（地图）来获取地图图层/源的方法？
