使用方法如下所示:
============================================
var sitePagination = $("#sitePagination").jqPaginator({
totalNum:0, //总条数
currentPage:1, //当前显示页
pageSize:10, //当前显示条目数
pagesSize:[5,10,50,100], //显示条目数 select
callback:function(pageSize,currentPage){ //回调函数
siteTotalFn(pageSize,currentPage);
}
})
// 初始化
siteTotalFn(sitePagination.opt.pageSize, 1);
// ajax 请求之后
sitePagination.setTotalNum(data.total);
sitePagination.setCurrentPage(currentPage);
