 function openWindow()

{

    var open=confirm("是否打开新的网站");  

if(open==true)

         { var asdf=prompt("请输入新的网站"，"http://www.imooc.com");

            if(asdf!=null) {window.open(asdf,"_blank",'width=400,height=500,munubar=no,toolbar=no');}

            else {alert("再见");}

        }

else {alert("再见");}

}
