点击地图获取栅格数据,报一下错误

下面是代码:
<template>
  <div>
      <div id='map' style="margin:0 auto;width: 1100px;height: 500px"></div>
      <div id="queryresult" style="width:100%;heigth:200px"></div>
      <div class="tip">"注:点击地图任意位置,案例以该位置进行栅格查询,查询完成后地图左下角会显示查询结果"</div>
  </div>
</template>
<script>
  export default {
    mounted () {
      this.map = new SuperMap.Map("map",{controls:[
        new SuperMap.Control.LayerSwitcher()]});

      this.map.events.on({
        "click": this.mapClicked
      });

      //新建点矢量图层
      this.pointLayer = new SuperMap.Layer.Vector("pointLayer");

      this.layer = new SuperMap.Layer.TiledDynamicRESTLayer("京津地区地图",this.url, {transparent: true, cacheEnabled: true});
      this.layer.events.on({"layerInitialized": this.addLayer});

    },
    data () {
      return {
        map: '',
        layer: '',
        pointLayer: '',
        str: '',

        this.map.setCenter(new SuperMap.LonLat(116.85 ,39.79), 2);
      },
      mapClicked (e) {

这个是新出的接口,你用我们 最新出的classic包 做试下
4月 25, 2018 用户: 孔祥 牛刀小试 (186 分)

谢谢,已经解决,我的是把

new webpack.optimize.CommonsChunkPlugin('common'),

删掉,如果不删掉的话,导致打包失败,不能把supermap相关的js全部导入到webpack中导致,js无法识别supermap语句

恩  ,classic的 包没有按照模块话打包 ,不支持 AMD和ES6 Model
有没有关于leaflet的
