    去掉多余的大括号，和最后多余的else就行了

    <!DOCTYPE html>
    <html>
     <head>
      <title> new document </title>  
      <meta http-equiv="Content-Type" content="text/html; charset=gbk"/>   
    <script type="text/javascript">  

     function openWindow(){

           var open=confirm("是否新建网页？");

      var url=prompt("通过输入对话框,确定打开的网址"," http://www.imooc.com");

    if(url!=null)

    {window.open(url,"_blank",'width=400px,height=500px,menubar=no,toolbar=no');}

    else

    {alert("再见！");}

    </script> 

     </head> 

     <body> 

     <input type="button" value="新窗口打开网站" onclick="openWindow()" /> 

     </body>

    </html>
