<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<form id="form1" name="form1" method="get" action="">
<input name="q1" type="text" id="q1" value="readonly" readonly="true" />
<input name="q2" type="text" disabled="disabled" id="q2" value="disabled" />
<input type="submit" name="Submit" value="Submit" />
</form>
</body>
</html>
小技巧：
diabled:可用readonly代替，background-color:#cccccc;加上灰色背景色就可以
