大家多少都自己写过各种版本的分页工具条吧，像纯服务版的，纯jsWeb板的，Angular版的，因为这个基础得不能再基础的功能太多地方都会用到，下面我给出以个用ReactJS实现的版本，首先上图看下效果：
注意这个组件需要ES6环境，最好使用NodeJS结合Webpack来打包：webpack --display-error-details --config webpack.config.js
此React版分页组件请亲们结合redux来使用比较方便，UI = Fn(State)
基本流程就是：用户交互->Action->Reduce->Store->UIRender
了解以上基础知识却非常必要，但不是我此次要说的重点，以上相关知识请各位自行补脑，废话就不多说，直接上代码。

附上Paging这个分页数据对象的结构paging.go服务端的Data Struct：
