对列表项进行分页
[英]Paginate an array of list items
问题描述
I'm having a bit of trouble add some pagination to this page. 
我在向该页面添加一些分页时遇到了麻烦。 The objective is to only have 10 list items show up at a time on every page. 目的是在每个页面上一次仅显示10个列表项。 I have have to add an event to the buttons so when they are click they show the corresponding items. 我必须在按钮上添加一个事件，以便在单击它们时显示相应的项目。
Here is what I have so far in this codepen http://codepen.io/temovargas/pen/mAqjaA 这是我到目前为止在此Codepen中拥有的内容http://codepen.io/temovargas/pen/mAqjaA

Have you tried a plugin such as DataTables or Jquery.paginate? 您是否尝试过诸如DataTables或Jquery.paginate之类的插件？ I've found home-brewing this kind of element exposes too many user cases to have to deal with later on. 我发现在家中学习这种元素会暴露出过多的用户案例，以至于日后不得不处理。 In my experience, a developed plugin will have grown to handle edge cases, etc. 以我的经验，开发的插件已经可以处理边缘情况等。
