    window.ovmap = new this.$mapboxgl.Map({
            container: "overviewMap",

          var map_x; //地图的x坐标

            map.setZoom(overview_zoom + 4);
          }
    
          map.on("drag", mapdrag);
          map.on("zoom", mapzoom);
          let overview = document.getElementById("overviewMap");
          overview.addEventListener("mouseover", function() {
            //移除地图的拖拽监听
            map.off("drag", mapdrag);
            map.off("zoom", mapzoom);
            //添加鹰眼的拖拽监听
            ovmap.on("drag", overviewdrag);
            ovmap.on("zoom", overviewzoom);
          });
          overview.addEventListener("mouseout", function() {
            //添加地图的拖拽监听
            map.on("drag", mapdrag);
            map.on("zoom", mapzoom);
            //移除鹰眼的拖拽监听
            ovmap.off("drag", overviewdrag);
            ovmap.off("zoom", overviewzoom);
          });

css:

#overviewMap {
        width: 160px;
        height: 160px;
        position: absolute;
        right: 10px;
        top: 200px;
        border: 2px solid gray;
      }
      .mapboxgl-ctrl-attrib {
        display: none;
      }
