JS分頁控件 可用於無刷新分頁

今天無意看到了這個分頁控件不過使用方法不是很清楚沒有研究大家可以自行研究裡面的函數寫法倒是不錯需要內容的結合  

　　JS分頁控件可用於無刷新分頁

復制代碼 代碼如下:
function PagerBar(recordcount pagesize pageindex showpagecount) {
    var NumberRegex = new RegExp(/^d+$/);
    thisPageIndex = ; //頁索引當前頁
    if (pageindex != null && NumberRegextest(pageindex)) thisPageIndex = parseInt(pageindex);
    thisPageSize = ; //頁面大小
    if (pagesize != null && NumberRegextest(pagesize)) thisPageSize = parseInt(pagesize);
    thisRecordCount = ;
    if (recordcount != null && NumberRegextest(recordcount)) thisRecordCount = parseInt(recordcount); //記錄總數
    thisPageCount = ;  //頁總數
    var PagerBar = this;
    function CalculatePageCount(_pagesize _recordcount) {//計算總頁數
        if (_pagesize != null && NumberRegextest(_pagesize)) PagerBarPageSize = parseInt(_pagesize);
        if (_recordcount != null && NumberRegextest(_recordcount)) PagerBarRecordCount = parseInt(_recordcount);
        else PagerBarRecordCount = ;
        if (PagerBarRecordCount % PagerBarPageSize == ) {//計算總也頁數
            PagerBarPageCount = parseInt(PagerBarRecordCount / PagerBarPageSize);
        }
        else {
            PagerBarPageCount = parseInt(PagerBarRecordCount / PagerBarPageSize) + ;
        }
    }
    if (thisRecordCount != ) {//如果傳入了記錄總數則計算總頁數
        CalculatePageCount(thisPageSize thisRecordCount);
    }
    thisReplaceString = "《#PageLink》"; //替換頁數的文本注不可以有正則表達式中的符號
