1、使用HTML <meta> 标签,中的 http-equiv 属性
经过一段时间转到另外某个页面
<meta http-equiv="refresh[刷新-这里指定动作]" content="5[这里是时间];url=/obge[这里是跳转的URL]">
如果只是一段时间刷新本界面,可以不使用 url 属性
页面定期刷新,如果加url的,则会重新定向到指定的网页,content后面跟的是时间(单位秒)
2、借助js 进行页面刷新,借助 setTimeout() 方法
<script type="text/javascript"> function myrefresh() { document.getElementById("<%=btnclick.ClientID%>").click(); setTimeout(‘myrefresh()‘, 1000); } </script>
3、也可只在局部刷新使用,具体
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ExcelMessage.aspx.cs" Inherits="qdAdmin_qdExcel_Excel_ExcelMessage" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <%-- <meta http-equiv="refresh" content="1" />--%> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="text/javascript"> function myrefresh() { document.getElementById("<%=btnclick.ClientID%>").click(); setTimeout(‘myrefresh()‘, 1000); } </script> <title></title> </head> <body style="background-color: white;" onload="myrefresh()"> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <div> <font color="red">请停止一切操作,直至数据操作完毕!</font> <hr size="1" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Button ID="btnclick" runat="server" Text="..." /> <%=base.ExcelUpLoadMessage %> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> </html>
赋值
private void GetChange() { while (true) { string strsql1 = "select count(*) from tbmdGongZiList where QiyeGuid=‘" + xEnterpriseGuid + "‘ and GongZiGuid=‘" + _GongZiGuid_new + "‘"; string strsql2 = "select count(*) from tbmdGongZiList where QiyeGuid=‘" + xEnterpriseGuid + "‘ and GongZiGuid=‘" + _GongZiGuid_old + "‘"; object obj1 = _bllGongZiList.GetScalarByTx(strsql1); object obj2 = _bllGongZiList.GetScalarByTx(strsql2); if (obj1 != DBNull.Value && obj2 != DBNull.Value) { base.ExcelUpLoadMessage = "当前正在复制:" + obj1.ToString() + " / " + obj2.ToString(); } else { return; } if (obj1 == obj2) { base.ExcelUpLoadMessage = "复制运算完毕,共更新了" + obj1.ToString() + "条数据,点击这里返回<input type=\"button\" onclick=\"javascript: window.history.back()\" value=\"返回\"/> "; return; } } }
