Javascript OpenLayers before zoom event listener

Question

I am trying to set up OpenLayers to not display the vector layer just before a zoom starts and make it reappear after a zoom ends. I have the zoom ends part already established

Answer 1

"movestart" handles "zoomstart". To detect if the zoomstart, try:

 map.events.register("movestart",map, function(e) {
        if(e.zoomChanged)
        {
        //zoom start code here
        }

    });
