我用了这个语句Response.Redirect( "inputerror.aspx "); 却实现不料这个功
能！在web.confirm表单中用户名和密码栏中也不允选有个相应的网址!各位大侠帮忙看看!先谢了!
[解决办法]
假设我用2个textBox分别输入用户名和密码
if(this.txt_userID.text!= " "){
if(this.txt_pass.text!= " "){Response.Redirect( "inputerror.aspx "); }
else{Response.Write( " <script> alert( "密码错误! "); </script> ");}
}
else {Response.Write( " <script> alert( "用户名错误! "); </script> ");
}
如果你建了数据库的话 你可以判断出密码是否和从数据库中取出来的一样不是的话报密码错误
