调用：

复制代码 代码如下:

var pageChange = function (index) {

var html = pager("divid", index, 5, 1000, pageChange, { showGoTo: false, showFirst: false });

}

实现：

复制代码 代码如下:

pager = function (divPager, pageIndex, pageSize, totalCount, pageChange, opt) {

var theOpt = {

barSize: 5, //分页条显示的页码数

barTemplate: "{bar}共{totalPage}页{totalCount}条{goto}", //显示模板

autoHide: true, //是否自动隐藏

showFirst: true, //在totalPage>barSize时是自动否显示第一页链接

showLast: true, //在totalPage>barSize时是自动否显示最后一页链接

showGoTo: true, //是否显示GoTo

autoHideGoTo: true //如果太少是否自动隐藏GoTo

};
