. 后台jsp参数处理
<%
@page
contentType=
"text/html;charset=GB2312"
%>
<html>
<head>
<title>
02
.jsp</title>
</head>
<body>
<%
request.setCharacterEncoding(
"GB2312"
);
String Name=request.getParameter(
"uname"
);
//获得参数数组
String Tech[]=request.getParameterValues(
"tech"
);
%>
<h1>姓名：<%=Name %></h1>
<h1>擅长技术：
<%
//输出数组
int
i;
for
(i=
0
;i<Tech.length;i++)
{
%>
<%=Tech[i] %>
<%
}
%>
</h1>
</body>
</html>
