JS分页控件 可用于无刷新分页

今天无意看到了这个分页控件不过使用方法不是很清楚没有研究大家可以自行研究里面的函数写法倒是不错需要内容的结合

JS分页控件可用于无刷新分页

复制代码 代码如下:
function PagerBar(recordcount pagesize pageindex showpagecount) {

thisRecordCount = ;
if (recordcount != null && NumberRegextest(recordcount)) thisRecordCount = parseInt(recordcount); //记录总数
thisPageCount = ; //页总数
var PagerBar = this;

}
