将数据库中的数据通过 client 控件显示
从浏览器到数据库关系：
browser
mschart control
javascript (client-side)
ASP (server-side vbscript)
ado
odbc
dbms
==================
关键在于将 RS 内的内容赋给 client-side javascript.
source code:
==================
<%@ LANGUAGE="VBSCRIPT" %>
<%
Dim oConn
Dim oRs
Dim curDir
Dim Index
Dim sqlstring
sqlstring = "select field from table"
' Create ADO Connection Component to connect
' with sample database
Set oConn = Server.CreateObject("ADODB.Connection")
oConn.Open "DSN=localserver;SERVER=(local);UID=sa;PWD=;DATABASE=pubs"
Set oRs = oConn.Execute(sqlstring)
%>
<script language=vbscript>
<% Response.Write "<!--" %>
Sub Window_onload()
Dim A
A = Array(<%
Do while (Not oRs.eof) %>
<% =Int(oRs(0))%>,<% oRs.MoveNext
Loop
%>0)
MSChart1.ChartType = 1
MSChart1.ChartData = A
End sub
<% Response.Write "-->" %>
</script>
<%
oRs.close
oConn.close
