asp+ajax，数据库中增加一条信息，自动弹出层

爵罗先生 2011-10-11 01:56:34

请问ajax读取到的新数据如何自动弹出层提醒？目前已经正常显示如：【您有N条未读消息】

接收页代码：



<%

Response.Buffer=True 

Response.ExpiresAbsolute=Now()-1 

Response.Expires=0 

Response.CacheControl="no-cache" 

Response.AddHeader "Pragma", "No-Cache"

%>

<!--#include file="conn.asp"-->

<!DOCTYPE html>

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

<title>个人中心</title>

<link href="images/img2.css" rel="stylesheet" type="text/css" />

<script>

function GetData()

{

url="xml.asp";

var http = new ActiveXObject("Microsoft.XMLHTTP");

http.open("GET",url,false);

http.send();

var str = http.responseText;

bb.innerHTML=str;

setTimeout("GetData()",1000);

}

</script>

</head>

<body onLoad="javascript:GetData();">

<div class="avatar"><span onclick="location.href='user.asp'" id="id2" style="cursor:pointer;">短消息<font color="#FF0000"><span id="bb">...</span></font></span></div>

</div>

<div id="fa">

  <div style="float:left; margin-left:10px; color:#0075A9; line-height:25px;"><strong>发送短消息</strong></div>

  <iframe name="fa2" width="500" height="450" scrolling="no" frameborder="0" id="fa2"></iframe>

</div>

<div id="ok">

  <div class="div" style="float:right;">

    <input type="submit" class="input" value="发短消息" onclick="document.getElementById('fa').style.display='block';fa2.location.href='message.asp';"/>

  </div>

</div>

</body>

</html>

ajax读取页面代码（xml.asp）：



<%

Response.Buffer=True 

Response.ExpiresAbsolute=Now()-1 

Response.Expires=0 

Response.CacheControl="no-cache" 

Response.AddHeader "Pragma", "No-Cache"

%>

<!--#include file="conn.asp"-->

<%

sql="select * from Chat_ID where ID2s="&session("ID")&" and Chat_ID=0"

set rs=server.createobject("adodb.recordset")

rs.open sql,conn,1,3

if rs.RecordCount=0 then

response.write""

else

%>

【您有<%=rs.RecordCount%>条未读消息】

<%end if%>
