vue 实现分页

1 新建 pager.js 文件

/**
 * [pagination 分页组件]
 * @param  {Number} total         [数据总条数]
 * @param  {Number} display     [每页显示条数 default:10]
 * @param  {Number} current     [当前页码 default:1]
 * @param  {Number} pagegroup     [分页条数(奇数) default:5]
 * @param  {Event} pagechange     [页码改动时 dispatch ]
 * @return {[type]}   [description]
