除了使用超链标签<a>以外，还有很多常见的网页转发方法
1）使用submit提交表单
default.html文件为：
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action=result.jsp><input type=text name=inputvalue></input><input
type=submit value=提交></form>
</body>
</html>
result.jsp文件为：
<%@page c%>
<html>
<head>
</head>
<body>
<%=request.getParameter("inputvalue")%>
</body>
</html>
2）使用一般按钮结合脚本提交表单
default.html文件为：
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action=result.jsp><input type=text name=inputvalue></input><input
type="button" value="提交" ></form>
</body>
</html>
<script language=javascript>
//客户端验证函数
function check()
{
document.forms[0].submit();
}
</script>
3）使用一般按钮结合脚本转发网页
default.html文件为：
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action=result.jsp><input type=text name=inputvalue></input><input
type="button" value="提交"
></form>
</body>
</html>
此时result.jsp不能显示正确内容，因为不是表单提交
4）使用servlet（最好、最灵活的方式）
default.html文件为：
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action=redirect><input type=text name=inputvalue></input><input
type="submit" value="提交"></form>
</body>
</html>
名称为Redirect的Servlet，映射名称为redirect
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Redirect extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
doGet(request, response);
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
if (!request.getParameter("inputvalue").equals("null")) {
RequestDispatcher disp = request.getRequestDispatcher("result.jsp");
disp.forward(request, response);
}
}
}
