맨날 까먹네. 그래서 적어놓음 var url = "링크"; var width= 800; var height= 600; var left= $(window).width()/2-width/2; var top= $(window).scrollTop() + $(window).height()/2 - height/2; window.open(url,'','top=' + top + ', left=' + left + ', width=' + width + ', height=' + height + ', toolbar=0, directories=0, status=0, menubar=0'); 뭐 이정도면 쓰것지...
