Kod ini agak mudah difahami dan boleh diubah suai mengikut keperluan anda sendiri Gaya yang digunakan di sini adalah anda sendiri

Kod gaya:

 .pages {display: inline-block; overflow: hidden;padding: 15px 0;text-align: center; width:100%; margin:50px 0;}

2. Cara menggunakan

2.1, paparan html

 <div class="second-ul-ctn">
   <ul class="second-ul" id="ulProducts">
   </ul>
  <div class="pages">
   <input type="hidden" id="hideTotalCount" />
    <div id="Pagination" class="pagination">
    </div>
   </div>
  </div>

ulProducts mengandungi data yang akan dipaparkan dan bar alat paging yang dijana diletakkan dalam Penomboran

Kod javascript 2.2

$(function () {
   searchMyme(0);
   pageInit();
   $("#btnSearch").on("click", function () {

    pageInit();
    return false;
   });
  });
  function searchMyme(page, pageination) {
   var month = $("#btnMonth").val();
   var obj = {
    Month: month,
    OpType: "getme",
    page: (page + 1)
    , rows: 10
   };
   var url = "../../Controler/FinaceMo/GetStaffIncome_H.ashx";
   $.get(url, obj, function (data) {

  function pageInit() {
   var totalCount = $("#hideTotalCount").val();
   $("#Pagination").pagination(parseInt(totalCount), {
