jQuery+Ajax implements refresh-free paging

1. The front desk uses ajax non-refresh paging. It mainly needs to generate a paging toolbar. The jquery.pagination.js is used here.
The code is posted below

/**
  * This jQuery plugin displays pagination links inside the selected elements.
  *
  * @author Gabriel Birke (birke *at* d-scribe *dot* de)
  * @version 1.2
  * @param {int} maxentries Number of entries to paginate
  * @param {Object} opts Several options (see README for documentation)
 * @return {Object} jQuery Object
 */
 jQuery.fn.pagination = function(maxentries, opts){
   opts = jQuery.extend({
   items_per_page:10,
   num_display_entries:10,
   current_page:0,
   num_edge_entries:0,

   next_show_always:true,

  },opts||{});
 
   return this.each(function() {
   /**

   function numPages() {
     return Math.ceil(maxentries/opts.items_per_page);
    }

}

The code is relatively easy to understand. , you can modify it according to your own needs. Here you use your own style

Style code:

.pages {display: inline-block; overflow: hidden;padding: 15px 0;text-align: center; width:100%; margin:50px 0;}
.pages b{ color:#e75f49;}
.pages a { color:#666; border: 1px solid #e5e5e5;cursor: pointer;font-size: 12px;margin-right: 5px; padding: 8px 12px; text-decoration: none; background-color:#fafafa;}
.pages .currentPage{ background-color: #00a0e9; border: 1px solid #00a0e9;color: #fff; font-weight: bold;}

The display effect is as follows:

Original css style:

.pagination a {
 text-decoration: none;
  border: 1px solid #AAE;
  color: #15B;
 }
 .pagination a, .pagination span {
  display: inline-block;
 padding: 0.1em 0.4em;
  margin-right: 5px;
 margin-bottom: 5px;
 }
  
.pagination .current {
 background: #26B;
 color: #fff;
 border: 1px solid #AAE;
 }
 .pagination .current.prev, .pagination .current.next{
  color:#999;
  border-color:#999;
  background:#fff;
 }

You can design the display style according to your own

2. Usage method

2.1. HTML display

<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 contains the required The displayed data and the generated paging toolbar are placed in Pagination

2.2 javascript code

$(function () {
   searchMyme(0);
   pageInit();
   $("#btnSearch").on("click", function () {
    searchMyme(0);
    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) {
    $("#tbIncome").empty();
    var obj = JSON.parse(data);
    var total = obj.Total;
    $("#hideTotalCount").val(total);
    var arrHtml = [];
    $.each(obj.Rows, function (i, data) {
     arrHtml.push("<tr><td>" + (i + 1) + "</td>");
     arrHtml.push("<td>" + data.Account + "</td>");
     arrHtml.push("<td>" + data.Name + "</td>");
     arrHtml.push("<td>" + data.Month + "</td>");
     arrHtml.push("<td>" + data.IncomeAmount + "</td>");
     arrHtml.push("<td><a href=&#39;MyDetail.aspx?Account="+data.Account+"&Month="+data.Month+"&#39; class=&#39;a-blue&#39;>查看明细</a></td></tr>");
    });
    $("#tbIncome").append(arrHtml.join(&#39;&#39;));
   });
  };
  function pageInit() {
   var totalCount = $("#hideTotalCount").val();
   $("#Pagination").pagination(parseInt(totalCount), {
    items_per_page: 10,
    //current_page: 1,//当前选中的页面默认是0，表示第1页
    num_edge_entries: 2,//两侧显示的首尾分页的条目数,默认为0，好像是尾部显示的个数
    num_display_entries: 2,//连续分页主体部分显示的分页条目数,默认是10
    link_to: "javascript:void(0)",//分页的链接
    prev_text: "上一页",
    next_text: "下一页",
    prev_show_always: true,
    next_show_always: true,
    callback: searchMyIncome
   });
  }

searchMyme is to obtain the paginated data and put the total into a hidden control. The paging control needs to be used. The ajax call here needs to be executed synchronously, otherwise the total number returned cannot be obtained. pageInit() is to initialize the control, so the setting is basically OK.

The above is the entire content of this article, I hope it will be helpful to everyone's study.
