	 markers[3].setMap(null);
	 markers[5].setMap(null);
	 markers[7].setMap(null);
	 markers[9].setMap(null);
	 }, false);
	 var markers = [], 
	 	positions = [

	 ];
	 for (var i = 0, marker; i < positions.length; i++) 
	 {
	 marker = new AMap.Marker({
	 map: map,
	 icon: 'http://webapi.amap.com/theme/v1.3/markers/n/mark_b'+(i+1)+'.png',
	 position: positions[i]
	 });
	 markers.push(marker);
	 }
	</script>
