还有一个叫做 category_get_goods 这个函数此函数新增了一个字段 collect返回字段可以用于前端页面视图渲染的时候实现判断是否已经搜藏 并且根据是否搜藏显示不同的样式和绑定不同的事件函数

总结

以前非常喜欢php 弄过一段时间 所以php代码也是基本上都能够看懂 mysql 也学过
没有php 基础的童鞋可以先去学学php基础
现在博主努力专研前端 后端也在学习 最近学习javascript 和 html5的新api 这些
记录下自己的工作

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

以上就介绍了基于ecshop的移动端 etouch实现动态获取分类商品列表，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。

你应该关心DependencyInjection(DI)，因为它能让你的代码更清晰、更易维护。1)DI通过解耦类，使其更模块化，2)提高了测试的便捷性和代码的灵活性，3)使用DI容器可以管理复杂的依赖关系，但要注意性能影响和循环依赖问题，4)最佳实践是依赖于抽象接口，实现松散耦合。
