用frameset实现查询页面和结果页面在同一页面
用target实现交互显示在同一页面上
请参照以下方法解决：
main.jsp: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=GBK"> <title>Insert title here</title> </head> <body> <frame> <iframe name="query" src="query.jsp"></iframe> <iframe name="list"></iframe> </frame> </body> </html> query.jsp: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Insert title here</title> </head> <body> <form action="list.jsp" method="post" target="list"> <input type="text" name="theName"> <input type="submit" value="Submit"> </form> </body> </html> list.jsp: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Insert title here</title> </head> <body> <%String result=request.getParameter("theName"); %> <%=result %> </body> </html>
