How to get current zoom level using gmaps.js?

Question

I use this

var allMap = new GMaps({
        el: '#map',
        zoom: 14,
        lat: userLat,
        lng: userLng,
        zoom_changed: function(e) {
            alert(allMap.zoom);
        }
    });

but I allways get alerted "14". I want to cacth specific zoom level and remove all marker if zoomed to much out. So I want to read the current(changed) zoom level on zoom_changed event.

在地图对象上使用getZoom（）方法返回当前缩放级别。
