jQuery Ajax implements refresh-free paging_jquery

1. Use ajax non-refresh paging at the front desk , which mainly needs to generate a paging toolbar. Here we use jquery.pagination.js
Post the code below

The code is relatively easy to understand and can be modified according to your own needs. The style used here is your own

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. How to use

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 data to be displayed, and the generated paging toolbar is 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='MyDetail.aspx&#63;Account="+data.Account+"&Month="+data.Month+"' class='a-blue'>查看明细</a></td></tr>");
    });
    $("#tbIncome").append(arrHtml.join(''));
   });
  };
  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 get the paging data and put the total in a hidden control. The total paging control needs to be used. The ajax call here needs to be executed synchronously, otherwise the returned total cannot be obtained. pageInit() is to initialize the control. This setting is basic That's OK.
