<body>

<form id="form" method="post" action="test.jsp">
<input type="radio" name="radiobutton" value="OK"/>
<input type="submit" value="提交"/>
</form>
<br/>
以下是从from里面读取的值：
<br/>
<%
String show=request.getParameter("radiobutton");
System.out.println(show);//显示在控制台
out.println(show);//显示在页面，显示结果为 OK
%>
</body>
</html>
