[page_break]其中最前面代碼,下面的理解是我自已想的有可能有錯，不過程序絕對沒有錯：<%
if not IsObject(session("cart")) then
Set session("cart")=CreateObject("Scripting.Dictionary")’建立二維數組
end if
Set cart=session("cart")
productID=Cstr(request("productID"))’定義變量productid為產品頁傳遞過來的值
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 ’上面這一段我看不太懂，誰知道告訴我一下，不過和下面的有關
end if
keys=cart.keys ’定義變量KEYS的值為數組里面的產品ID
items=cart.items ’定義變量items的值為數組里面的產品數量
set session("cart")=cart
%>
代碼二：
<% For i = 0 To cart.Count -1 %> ’設置多個產品的循環，cart.count是指購買幾個產品,后面要以next結束
<% Dim list__MMColParam
list__MMColParam = keys(i) %> ’定義ID為cart數組里面的產品ID號
<% 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()
%> ’上面的代碼就不用我說了，其中要注意的：list__MMColParam = keys(i)
………………………………………… <%
list.Close()
%>
<% next %>

取消訂購的產品：delcart.asp

if request("productID")<>"" then

上面用了兩個命令預存過程：
第一個過程：list
存儲產品到數據庫
因為有可能選購多個產品，所以用了一個循環For i = 0 To cart.Count -1,并以next結束
第二個過程：add
存儲客戶到數據庫
就這樣一個簡單的購物車做好了。
本教程中主要的是cart.asp中的定義一個二維數組，還有用循環For i = 0 To cart.Count -1 next 把所訂購的產品顯示出來
