js部分

总结：  
1、这个的样式是我从js代码大全仿造的，他原来的代码时用jq写的，好吧！其实我还不会jq。  
2、第二个页面是不能够同步更新cookie中的内容的，不过要实现也是可以的，将每次点击加号或者减号后的商品列表的数量更新到cookie中就行了。（好吧！至少我是这么想的）  
3、在向cookie中添加内容的时候，会出现id值为NUll的情况，虽然我加了必须要id存在的条件才能设置cookie，但是并不清除为什么会出现这种情况。  
4、看到我写的博客会有大于1的浏览量，我好慌张，因为我只是用这个博客在存代码和观察自己的学习进度。写的代码质量又不高，好担心会误导看到的人，罪过……  
5、继续学习吧！然后再回来调整或者写个新的页面
