2 * pagination.js 1.5.1
3 * A jQuery plugin to provide simple yet fully customisable pagination.
4 * @version 1.5.1
5 * @author mss
6 * @url https://github.com/Maxiaoxiang/jQuery-plugins
7 *
8 * @调用方法
9 * $(selector).pagination(option, callback);
10 * -此处callback是初始化调用，option里的callback是点击页码后调用
11 * 
12 * -- example --
13 * $(selector).pagination({
14 *     ... // 配置参数
15 *     callback: function(api) {
16 *         console.log('点击页码调用该回调'); //切换页码时执行一次回调
17 *     }
18 * }, function(){
19 *     console.log('初始化'); //插件初始化时调用该方法，比如请求第一次接口来初始化分页配置
20 * });
