使用DataTable插件實現(xiàn)異步加載數(shù)據(jù)

本文給大家分享的是Jquery+dataTable插件來實現(xiàn)異步加載數(shù)據(jù)的示例代碼，非常實用，有需要的小伙伴可以參考下

table部分代碼

<table class="table table-bordered table-striped" id="table-main">
  <thead>
  <tr>
    <th>用戶名</th>
    <th>渠道名</th>
    <th>游戲名</th>
    <th>結(jié)果</th>
    <th>耗時</th>
    <th>創(chuàng)建時間</th>
  </tr>
  </thead>
</table>

異步加載數(shù)據(jù)并實現(xiàn)定制化

下面是簡單例子, 其中 table-main 的初始化元素為table的id。

$('#select-game').select2(); // 初始化搜索下拉框
 
       // 表格漢化列表
  var table_lang = {
    "sProcessing": "處理中...",
    "sLengthMenu": "每頁 _MENU_ 項",
    "sZeroRecords": "沒有匹配結(jié)果",
    "sInfo": "當(dāng)前顯示第 _START_ 至 _END_ 項，共 _TOTAL_ 項。",
    "sInfoEmpty": "當(dāng)前顯示第 0 至 0 項，共 0 項",
    "sInfoFiltered": "(由 _MAX_ 項結(jié)果過濾)",
    "sInfoPostFix": "",
    "sSearch": "搜索:",
    "sUrl": "",
    "sEmptyTable": "表中數(shù)據(jù)為空",
    "sLoadingRecords": "載入中...",
    "sInfoThousands": ",",
    "oPaginate": {
      "sFirst": "首頁",
      "sPrevious": "上頁",
      "sNext": "下頁",
      "sLast": "末頁",
      "sJump": "跳轉(zhuǎn)"
    },
    "oAria": {
      "sSortAscending": ": 以升序排列此列",
      "sSortDescending": ": 以降序排列此列"
    }
  };
 
  //初始化表格
  var table_main = $("#table-main").dataTable({
    language:table_lang,  // 提示信息
    autoWidth: false,   // 禁用自動調(diào)整列寬
    lengthMenu: [25, 50, 100],
    stripeClasses: ["odd", "even"], // 為奇偶行加上樣式，兼容不支持CSS偽類的場合
    processing: false,   // 隱藏加載提示,自行處理
    serverSide: true,   // 啟用服務(wù)器端分頁
    searching: true,    // 啟用原生搜索
    orderMulti: true,   // 啟用多列排序
    order: [],       // 取消默認(rèn)排序查詢,否則復(fù)選框一列會出現(xiàn)小箭頭
    renderer: "bootstrap", // 渲染樣式：Bootstrap和jquery-ui
    pagingType: "simple_numbers", //分頁樣式：simple,simple_numbers,full,full_numbers
    columnDefs: [{
      "targets": 'nosort', // 列的樣式名
      "orderable": false  // 包含上樣式名‘nosort'的禁止排序
    }],
    ajax: function (data, callback, settings) {
      //封裝請求參數(shù)
      var param = {};
      param.limit = data.length; // 頁面顯示記錄條數(shù)，在頁面顯示每頁顯示多少項的時候
      param.start = data.start; // 開始的記錄序號
      param.page = (data.start / data.length)+1; // 當(dāng)前頁碼
      //ajax請求數(shù)據(jù)
      $.ajax({
        type: "GET",
        url: "getRecodeList",
        cache: true, // 開啟緩存
        data: param, // 傳入組裝的參數(shù)
        dataType: "json",
        success: function (result) {
//              console.log(result);
          //setTimeout僅為測試延遲效果
          setTimeout(function () {
            //封裝返回數(shù)據(jù)
            var returnData = {};
            returnData.draw = data.draw;       // 這里直接自行返回了draw計數(shù)器,應(yīng)該由后臺返回
            returnData.recordsTotal = result.total;  // 返回數(shù)據(jù)全部記錄
            returnData.recordsFiltered = result.total;// 后臺不實現(xiàn)過濾功能，每次查詢均視作全部結(jié)果
            returnData.data = result.data;      // 返回的數(shù)據(jù)列表
            //console.log(returnData);
            // 調(diào)用DataTables提供的callback方法，代表數(shù)據(jù)已封裝完成并傳回DataTables進行渲染
            // 此時的數(shù)據(jù)需確保正確無誤，異常判斷應(yīng)在執(zhí)行此回調(diào)前自行處理完畢
            callback(returnData);
            cut_td($("#table-main"), 40); // 表格截斷
 
          }, 200);
        }
      });
    },
    //列表表頭字段
    columns: [
      { "data": "user_name" },
      { "data": "channel" },
      { "data": "game" },
      { "data": "status",
        "render": function(data){
          var status_name = '';
          switch(data)
          {
            case 0: status_name = '未完成'; break;
            case 1: status_name = '腳本錯誤'; break;
            case 2: status_name = '成功'; break;
            case 3: status_name = '測試通過'; break;
            default : status_name = '未知'; break;
          }
          return status_name;
        }},
      { "data": "cast_time",
        "render" : function(data){
          if (data)
          {
            return data + 's';
          }
          else
          {
            return '廢棄';
          }
        }},
      { "data": "format_created_at" },
    ]
  }).api();
