.net页面定时刷新的几种简单方式

1:

window.setTimeout("window.location.href='Default5.aspx?timestamp="+Date.parse(new Date())+"'",1000);

  

2:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
        setTimeout("document.getElementById(\"Button1\").click()",3000);
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" style="display:none;" />
    </div>
    </form>
</body>
</html>

 

后台:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default5 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Write(DateTime.Now);
    }
}

 

3:

    Response.AddHeader("refresh","10;url=Default5.aspx");

 

4:

 <meta http-equiv="refresh" content="3;url=Default5.aspx" />
      <meta http-equiv="refresh" content="3" /><!--如果不知道那个URL则默认为当前页-->

 5:

   StringBuilder script = new StringBuilder();
            script.Append("<script type=\"text/javascript\">\n");
            script.Append("window.setInterval('postme()',3000)\n");
            script.Append("function postme(){\n");
            script.Append("document.forms[0].submit();\n");
            script.Append("}\n");
            script.Append("</script>\n");
            Page.ClientScript.RegisterStartupScript(this.GetType(),"refresh",script.ToString());

 6:将刷新时间放到配置文件里:

<meta http-equiv="refresh" content="<%= System.Configuration.ConfigurationManager.AppSettings["test"].ToString() %>" />

 

  <add key="test" value="3"/>
