关于传值的问题
我在框架页A页面里进行查询,将查询的结果在B页面里显示.可是查询的结果还在A页面里显示,为什么不在B页里显示呢??我用include也不行啊!!谁能帮帮忙啊?
A代码
<%@ page language= "java " import= "java.util.* " pageEncoding= "GB2312 "%>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> </title>
</head>
<body>
<br/>
<h3> <div align= "center " > 查询用户 </h3>
<table width= "176 " height= "88 " border= "1 ">
<form name= "form1 " method= "post " action= "query.jsp ">
<tr>
<td width= "76 "> 查询方式: </td>
<td >
<select name= "select " size= "1 ">
<option value= "1 "> ID号 </option>
<option value= "2 "> 姓名 </option>
<option value= "3 "> 性别 </option>
<option value= "2 "> 年龄 </option>
<option value= "2 "> 邮箱 </option>
</select> </td>
</tr>
<tr>
<td> 查询内容: </td>
<td width= "76 "> <input type= "text " name= "txtwhere " size= "10 "> </td>
</tr>
<tr>
<td align= "center "> <input type= "submit " name= "subt " value= "提交 "> </td>
<td align= "center " > <input type= "reset " name= "reset " value= "重写 "> </td>
</tr>
</form>
</table>
</body>
</html>
B页代码
<%@page language= "java " import= "java.util.* " pageEncoding= "GB2312 "%>
<jsp:directive.page import= "com.zjw.db.Db " />
<jsp:directive.page import= "java.sql.ResultSet " />
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> </title>
</head>
<body>
<table border= "1 ">
<% Db db = new Db();
String sel = request.getParameter( "select ");
String txtwhere = request.getParameter( "txtwhere ");
ResultSet rs=null;
if(sel==null && txtwhere==null){
rs=db.userInfo();
}else{
rs = db.userQuery(sel, txtwhere);
}
String sex = " ";
while (rs.next()) {
String s = rs.getString(4);
Integer ints = new Integer(s);
if (ints == 1) {
sex = "男 ";
} else {
sex = "女 ";
}
out.println( " <tr > ");
out.println( " <td width= '50 ' align= 'center '> ID </td> ");
out.println( " <td width= '50 ' align= 'center '> 名字 </td> ");
out.println( " <td width= '50 ' align= 'center '> 性别 </td> ");
out.println( " <td width= '80 ' align= 'center '> 年龄 </td> ");
//out.println( " <td> 邮箱 </td> ");
out.println( " <td width= '120 ' align= 'center '> 住址 </td> ");
//out.println( " </tr> ");
out.println( " <tr> ");
out.println( " <td align= 'center '> " + rs.getString( "uid ") + " </td> ");
out.println( " <td align= 'center '> " + rs.getString( "uname ") + " </td> ");
out.println( " <td align= 'center '> " + sex + " </td> ");
out.println( " <td align= 'center '> " + rs.getString( "uage ") + " </td> ");
//out.println( " <td> "+rs.getString( "uemail ")+ " </td> ");
out.println( " <td align= 'center '> " + rs.getString( "uaddress ") + " </td> ");
out.println( " </tr> ");
}
rs.close();
db.close();
%>
</table>
</body>

[解决办法]
将A的JSP
<form name= "form1 " method= "post " action= "query.jsp ">
改为试一试
<form name= "form1 " method= "post " action= "query.jsp " target= "_blank ">
