评论完,每次刷新页面,都会弹出 "评论成功！" 评论条数也增加了.

Question

有两个问题:1,评论成功之后,清空了编辑框, 然后刷新页面,竟然还会弹出"评论成功！"  评论数目也增加了.2, 评论完成之后, 顺便刷新页面,怎么弄? 
       protected void Reply_Click(object sender, EventArgs e)
        {
                if (ReplyBox.Text.Trim() == "")
                {
                    Response.Write("<script language=javascript>alert('评论内容不能为空！');location='javascript:history.go(-1)'</script>");
                    Response.End();
                }
                else
                {
                    try
                    {
                        if (cn.State == System.Data.ConnectionState.Closed)
                        {
                            cn.Open();
                        }
                        string reply_sql = "insert into reply (content,id,date) values ('" + ReplyBox.Text + "','" + Request.QueryString["id"] + "','" + DateTime.Now.ToString("yyyy-MM-dd") + " " + DateTime.Now.ToString("HH:mm:ss") + "')";
                        SqlCommand com_r = new SqlCommand(reply_sql, cn);
                        com_r.ExecuteNonQuery();
                        Response.Write("<script language=javascript>alert('评论成功！');</script>");
                        ReplyBox.Text = "";
                    }
                    catch
                    {
                        Response.Write("<script language=javascript>alert('评论失败！');location='javascript:history.go(-1)'</script>");
                    }
                    finally
                    {
                        cn.Close();
                    }
                }        }

Answer 1

用Respose.Redirect(Request.RawRul);//刷新会把你上一次成功提交的数据重新提交的

Answer 2

就是不知道怎样跳转, 这个是带参数的页面.
用location='javascript:history.go(0)行吗?

Answer 3

在提交成功之后加这个Response.Redirect(Request.RawUrl);

Answer 4

这个可以.不过貌似不能跟Response.Write("<script language=javascript>alert('Ok');</script>");
同时使用啊,
这个弹出框就失效了.                    try
                  {.
.
.                        SqlCommand com_r = new SqlCommand(reply_sql, cn);
                        //执行SQL语句
                        com_r.ExecuteNonQuery();
                        //SQL语句执行成功，返回true值
                        string aid = Request.QueryString["id"];
                        Response.Write("<script language=javascript>alert('评论成功！');</script>");
                        Response.Redirect("Article.aspx?id="+aid);
                    }

Answer 5

Response.Write("<script>alert('评论成功！');location.reload();</script>");

Answer 6

            Response.Clear();
            string script = "<script>alert('添加成功!'); location.href='" + Request.RawUrl + "'</script>";
            Response.Write(script);
            Response.End();

Answer 7

Response.Write（“<script>location.href=‘’</script>”）  提交本页面不就行了……  真复杂。

Answer 8

Response.Write("<script language=javascript>alert('评论成功！');location.href=location.href</script>");
