c制作购物车_用html做一个购物车能实现简单的产品数量和价格的加减就行最后能计算出提交物品价格的总和

① excel表格怎么制作加入购物车的功能

alt+F11打开VBE编辑器，双击左侧工程管理器thisworkbook标签，粘贴以下代码，内如图操作容

Sub mm()

r = Sheets("sheet2").Range("c65536").End(xlUp).Row + 1

Selection.Copy Sheets("sheet2").Range("c" & r)

End Sub

② JSP，购物车生成订单，急求代码！！

// end else if
my_mc.cat._visible =0;
dati = filexml.firstChild.childNodes[categoriasito].childNodes;
for (i=0; i<dati.length; i++) {
容my_mc.cat.plicateMovieClip("cat"+i, i*1+5000);
my_mc["cat"+i].loader.loadMovie(dati[i].attributes.urlimage);
my_mc["cat"+i].input_txt.text = dati[i].attributes.desc;
if (i<colonne) {
my_mc["cat"+i]._y = 0;
my_mc["cat"+i]._x = 105*i+20;
} else {

⑤ 我想用C++编程自动提取页面购物车里商品的名称和数量，该用什么函数

要看什么平来台了，这种自如果是指从Web页面抓取内容的任务，Python比C/C++要实现方便资料也更容易找到。当然C/C++也可以，比如用Linux上的curl库，Windows上的WinInet库都可以操作HTTP协议

⑥ 淘宝C店现在用什么做购物车营销

淘宝C店现在用什么做购物车营销的步骤如下：

首先打开淘宝首页，登录卖家中回心，答在左边导航栏找到【淘宝营销中心】点击进入；
进入营销中心后，点击【立即设置】购物车营销；
再点击【创建活动】订购购物车营销功能；
填写活动名称，设置活动开始时间和结束时间；
选择勾选活动对象和优惠即可。

⑦ 有没有高手能帮小弟做一个C语言或者JAVA语言的购物车模块，急求交作业啊我的邮箱是416561897@qq. com

什么时候交作业？

⑧ 我要C# 淘宝购物车源代码一份，我最近在弄购物车，弄不出来，我的邮箱[email protected]，谢谢

可以参考这里：
http://download.csdn.net/detail/ChinaUndDeutsch/525006
http://www..com/s?tn=home_pg&ie=utf-8&bs=C%23%E4%B8%AD%E5%AF%86%E5%B0%81%E7%B1%BB%E5%92%8C%E5%AF%86%E5%B0%81%E6%96%B9%E6%B3%95&f=8&rsv_bp=1&rsv_spt=1&wd=%E8%B4%AD%E7%89%A9%E8%BD%A6%E6%BA%90%E4%BB%A3%E7%A0%81&rsv_n=2&rsv_sug3=1&inputT=344

⑨ MVC模式编写购物车代码

需求写的不错啊。可以实现了，首先看下需要什么表，根据实体建表，然后对这些表进行增删改查就ok了。
购物车要注意处理事务。

⑩ 用html做一个购物车，能实现简单的产品数量和价格的加减就行。最后能计算出提交物品价格的总和。

html中的购物车的增减不能直接传送到后台，可以通过ajax，在js中发送ajax

纯前端的话可以参考下面的
