vue使用高德地图点击下钻上浮效果的实现思路

//创建地图
  this.map = new AMap.Map("container", {
   cursor: "default",
   resizeEnable: true,
   expandZoomRange: true,
   gestureHandling: "greedy",
   // zooms: [8, 20],
   zoom: 12,
   defaultCursor: "pointer",
   mapStyle: "amap://styles/f6e3818366ba5268d50ea3f2296eb3eb",
   showLabel: true
  });

let that = this;
  AMapUI.loadUI(["geo/DistrictExplorer"], DistrictExplorer => {
   //创建一个实例
   that.districtExplorer = new DistrictExplorer({
   eventSupport: true,
   map: this.map
   });

   //设置绘制的子区域和父区域的自身属性（包括线颜色，透明度等）执行renderAreaNode（）就可以开始绘制区域了
   function renderAreaNode(areaNode) {
   //绘制子级区划
   that.districtExplorer.renderSubFeatures(areaNode, function(
    feature,
    i
   ) {
    return {
    cursor: "default",
    bubble: true,
    // strokeColor: "#00a4ce", //线颜色
    strokeColor: "#03d7a1",
    strokeOpacity: 1, //线透明度
    strokeWeight: 1.5, //线宽
    // fillColor: "#09152a", //填充色
    fillColor: "#072942",
    fillOpacity: 0.1 //填充透明度
    };
   });
   //绘制父区域
   that.districtExplorer.renderParentFeature(areaNode, {
    cursor: "default",
    bubble: true,
    // strokeColor: "#00a4ce", //线颜色
    strokeColor: "#03d7a1",
    strokeOpacity: 1, //线透明度
    strokeWeight: 1.5, //线宽
    // fillColor: "#09152a", //填充色
    fillColor: "#072942",
    fillOpacity: 0.6 //填充透明度
   });
   }

   // var adcodes = [];
   // //根据角色来绘制不同的区域
   // that.adcodes = [
   // 330200 //浙江
   // ];
   that.map.clearMap(); //清空所有绘制物
   //绘制多区域
   that.districtExplorer.loadMultiAreaNodes(this.adcodes, function(
   error,
   areaNodes
   ) {
   //设置定位节点，支持鼠标位置识别
   //注意节点的顺序，前面的高优先级
   that.districtExplorer.setAreaNodesForLocating(areaNodes);
   //清除已有的绘制内容
   that.districtExplorer.clearFeaturePolygons();
   for (var i = 0, len = areaNodes.length; i < len; i++) {
    renderAreaNode(areaNodes[i]);
   }
   //更新地图视野
   that.map.setFitView(that.districtExplorer.getAllFeaturePolygons());
   });
   //添加点标记
   that.addMarker(data);
  });

if (data.result.rows[0].cities_name == "杭州市") {
   this.adcodes = [330100];
