javascript去掉菜单栏、工具栏

var open_flag=window.open("","","width="+(window.screen.availWidth)+",height="+(window.screen.availHeight)+",left=0,top=0,toolbar=no,menubar=no,status=yes,location=no,scrollbars=yes,resizable=yes");
open_flag.location.href="<%=request.getContextPath()%>/main.jsp";  
if(open_flag== null){  
    location="<%=request.getContextPath()%>/main.jsp";  
 }  
 else  
 {  
   focus();  
   window.opener =window.self;  
   window.open("","_self");  
   window.close();  

}

貌似在ie9里面没有效果
