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.
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?

C# code

        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();                    }                }        }

[解决办法]
评论成功之后，直接重新加载本页面，这样就不会啦，要不然你刷新页面时，会记录一些状态
[解决办法]

C# code

            Response.Clear();            string script = "<script>alert('添加成功!'); location.href='" + Request.RawUrl + "'</script>";            Response.Write(script);            Response.End();
[解决办法]
Response.Write（“<script>location.href=‘’</script>”）  提交本页面不就行了……  真复杂。
[解决办法]
Response.Write("<script language=javascript>alert('评论成功！');location.href=location.href</script>");
