asp.net页面防刷新重复提交

1、继承类库里的防刷新

  Public Function fangshuaxin()        If Session("logintime") Is Nothing Then            Session("logintime") = Now            Session("yemian") = Request.RawUrl.ToString        Else            If Request.RawUrl = Session("yemian") Then                '访问同一页面时必须间隔一秒钟                If Now > CDate(Session("logintime")).AddMilliseconds(500) Then                    Session("logintime") = Now                Else                    Msg("为了避免出现服务器超负荷，系统开启了防刷新机制，请间隔1秒钟以上再继续")                End If            Else                Session("logintime") = Now                Session("yemian") = Request.RawUrl.ToString            End If

        End If    End Function

 

2、页面提交后转入其它页面

       Response.Write("<script language=javascript>alert('下单提交成功，点【确定】后转入会员控制面板！');window.location.href='user/index_user.aspx';</script>")
