Question

我做了一个404页面，我想几秒后自动跳转到上一页

Answer 1

把上一页的url通过querystring传到这个404页面，用js在404页面的onload事件里定时跳回：setInterval("window.location=" + 上一页的url, 1000); //1秒钟后跳回

Answer 2

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (Request.UrlReferrer != null)
            {
                ViewState["UrlReferrer"] = Request.UrlReferrer.ToString();
            }
            else
                ViewState["UrlReferrer"] = "";
        }
    }
 if (ViewState["UrlReferrer"].ToString() != null && ViewState["UrlReferrer"].ToString() != "")
            {
                if (ViewState["UrlReferrer"].ToString().IndexOf("TopicCategory.aspx") > 0)
                {
                    Response.Redirect("bbs/index.html");
                    return;
                }
                HyperLink1.NavigateUrl = (string)ViewState["UrlReferrer"];
                HyperLink1.Text = (string)ViewState["UrlReferrer"];
                HyperLink1.Visible = true;
                string JsFunc = @"var hrefr=document.getElementById('HyperLink1').innerHTML;setTimeout('window.location.href=hrefr;',5000);";//5秒后返回
                Page.ClientScript.RegisterStartupScript(this.GetType(),
               "Script", JsFunc, true);
            }

Answer 3

  <script type="text/javascript">
        setTimeout(GotoNextPage, 3000);
        function GotoNextPage() {
            window.history.back(-1); 
        }
    </script>  已经实现,把上面的方法加入页面

Answer 4

Response.Write("<script>window.setTimeout(\"window.location='Default2.aspx'\",12000);</script>");这个也行噢
 Response.Write("<script>setInterval(\"window.location='Default2.aspx'\", 1000);</script>");//这个也可以
