jquery实现同时展示多个tab标签+左右箭头实现来回滚动

内容：

小颖最近的项目要实现类似如下效果：

蓝色框圈起来的分别是向上翻、向下翻俩按钮。绿色框分别是用户点击菜单后，出现相应的tab标签，当tab标签太多内容显示不下时，左右两边的按钮就可以实现看后面的tab标签和看之前的tab标签。小颖一开始想使用bootstrap的轮播图 carousel插件，后来发现行不通，就开始问度娘，偶然间发现了别人发表的：jquery同时展示多张图片+定时向左单张滚动+前后箭头插件，小颖将其修修改改后实现了自己想要的功能：jquery实现同时展示多个tab标签+左右箭头实现来回滚动

jquery实现同时展示多张图片+定时向左单张滚动+前后箭头插件

这个由于图片太大，小颖就不给大家看效果图了，感兴趣的可以把代码复制下来，自己运行后看下具体的效果图时怎样的。
