列出产品，这里有一个要点就是：<a href="cart.asp?ProductID=<%=(Recordset1.Fields.Item("id").Value)%>&quantity=1">购买</a>
这里传递了两个参数：产品ID“ProductID" 数量：“quantity"

[page_break]其中最前面代码,下面的理解是我自已想的有可能有错，不过程序绝对没有错：<%
if not IsObject(session("cart")) then
Set session("cart")=CreateObject("Scripting.Dictionary")’建立二维数组
end if
Set cart=session("cart")
productID=Cstr(request("productID"))’定义变量productid为产品页传递过来的值
dim detail(1)
detail(0)=Int(request("quantity"))
if request("productID")<>"" then
if cart.Exists(productID) then
cart.Remove(productID)
end if
cart.add productID,detail ’上面这一段我看不太懂，谁知道告诉我一下，不过和下面的有关
end if
keys=cart.keys ’定义变量KEYS的值为数组里面的产品ID
items=cart.items ’定义变量items的值为数组里面的产品数量
set session("cart")=cart
%>
代码二：
<% For i = 0 To cart.Count -1 %> ’设置多个产品的循环，cart.count是指购买几个产品,后面要以next结束
<% Dim list__MMColParam
list__MMColParam = keys(i) %> ’定义ID为cart数组里面的产品ID号
<% set list = Server.CreateObject("ADODB.Recordset")
list.ActiveConnection = MM_conn_STRING
list.Source = "SELECT * FROM pro_table WHERE id = " + Replace(list__MMColParam, "’", "’’") + ""
list.CursorType = 0
list.CursorLocation = 2
list.LockType = 3
list.Open()
%> ’上面的代码就不用我说了，其中要注意的：list__MMColParam = keys(i)
………………………………………… <%
list.Close()
%>
<% next %>

取消订购的产品：delcart.asp

<%
Set cart=session("cart")
if request("productID")<>"" then
productID=Cstr(request("productID"))
cart.Remove(productID)
end if
set session("cart")=cart
response.redirect("cart.asp")

上面用了两个命令预存过程：
第一个过程：list
存储产品到数据库
因为有可能选购多个产品，所以用了一个循环For i = 0 To cart.Count -1,并以next结束
第二个过程：add
存储客户到数据库
就这样一个简单的购物车做好了。
本教程中主要的是cart.asp中的定义一个二维数组，还有用循环For i = 0 To cart.Count -1 next 把所订购的产品显示出来
