错误地方
还有,你定义了两遍html,把前6行删了就好了
<!DOCTYPE html>
<html>
<head>
<title> new document </title>
<meta http-equiv="Content-Type" content="text/html; charset=gbk"/>
<script type="text/javascript">

{var url=prompt("请输入网址","http://www.imooc.com/");
if(url!=null)
{window.open(url,"_blank",'width=400px,height=400px,menubar=no,toolbar=no');
}
else{alert("再见");
}
}
else{alert("再见");
}
}

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