First, add a hidden page to the framework, as shown below:

<HTML>
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312">
<Title> </title>
<Script language = "JavaScript">
Function re ()
{
Window. setTimeout ("re ()", 30000 );
Iframepopmsg.doc ument. Location. href = "search. asp"
}
</SCRIPT>
</Head>
<Body topmargin = "0" leftmargin = "0" onLoad = "re ();">
<IFRAME Height = "1" scrolling = "no" frameborder = "0" width = "1" id = "iframepopmsg" src = "about: blank"> </iframe>
</Body>
</Html>

The function of this page is not to refresh the search. ASP page every 30000 milliseconds. Below is the search. aspCode

<Head>
<%
Set rs = server. Createobject ("ADODB. recordset ")
SQL = "select ID from XXXX where XXXX"
Rs. Open SQL, Conn, 3, 2
If not Rs. EOF then
%>
<Script language = "JavaScript">
Newwin = Window. Open ("New. asp? Id = <% = RS ("ID") %> "," "," Top = 50, Left = 50, width = 420, Height = 262, menubar = No, status = No, scrollbars = Yes, location = No, toolbar = No ")
Newwin. Focus ();
</SCRIPT>
<%
End if
Rs. Close
Set rs = nothing
Connend
%>
</Head>

In this way, if there is a message that meets the query conditions, the new. ASP page will pop up, And the ID will be passed over. The following is how the pop-up page is displayed, which is not detailed here.
