　　在以上代码中，我们可以通过产品模型迭代来生成产品列表。它会显示产品名称、产品图片、以及产品价格。

　　运行以下程序，在浏览器中键入以下URL地址http://localhost/Product/，你会看到一个屏幕，从产品列表中将产品拖拽至购物车中。你会注意到当你将产品添加至购物车里，购买物品的总价会自动更新。你也可以使用清除购物车按钮来清除整个购物车的物品。你还可以通过选中指定产品的图片来取消单个产品的购买。当你取消购买单个产品的时候，总体价格会扣除取消购买产品的价格。购买产品的总体数量也会相应减少。

　　在电子商务的应用程序中，通过使用这个插件可以为终端用户提供更多的交互性。希望这篇文章对你也有所帮助。
