AMap.event.addListener(map,'click',function(e){

   // map.zoomIn();
   // alert(EventListener);

});

把这里的map对象改成marker对象，比如我定义了

        var _marker = new AMap.Marker({
            map: map,
            icon: marker.icon,
            position: [marker.position[0], marker.position[1]],
            offset: new AMap.Pixel(-12, -12),
            draggable : true, //可拖拽
            // raiseOnDrag : true , //离开地图效果
            clickable : true , //是否可点击
        });
        AMap.event.addListener(_marker,'dragend',_drag);
