从api创建传单标记

Question

我需要帮助进行作业，我试图使api jcdecaux中的标记从传单上显示在我的地图上，但是它不起作用我不知道我在做什么错，您能帮我吗？

我的javascript代码station.js获取api：

function Station () {
  this.stations = [];

  this.getAllStations = function () {
    var bookedStation = sessionStorage.getItem('bookedStation');

    ajax.get("https://api.jcdecaux.com/vls/v1/stations?contract={brisbane}&apiKey={7042c878507ac81a3c944a451f00ca5c58273ad9}", function (reponse) {
      // Tab JavaScript
      this.stations = JSON.parse(reponse);

      //get the stations
      this.stations.forEach(function(station){
        if (bookedStation != null) {
          bookedStation = JSON.parse(sessionStorage.getItem('bookedStation'))
        }
        else {
          bookedStation = null
        }

        //reservertion from the api
        if (bookedStation != null && bookedStation.number == station.number && bookedStation.available_bikes < station.available_bikes) {
          station.available_bikes = bookedStation.available_bikes;
        }

        //create marker to the function create marker in map.js
        map.createMarker(station)
      })
    }.bind(this));
  }
}

这是我的另一张javascript地图map.js文件

window.onload = function () {
  var mymap = L.map('mapid').setView([-27.461354, 153.025396], 13);
  L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token={accessToken}', {

  }).addTo(mymap);

  this.createMarker = function(station) {
    var marker = new L.marker([lat,lon],{}).addTo(map);                        
  };            
};
