使用DataTable插件实现异步加载数据

table部分代码

<table class="table table-bordered table-striped" id="table-main">
  <thead>
  <tr>
    <th>用户名</th>
    <th>渠道名</th>
    <th>游戏名</th>
    <th>结果</th>
    <th>耗时</th>
    <th>创建时间</th>
  </tr>
  </thead>
</table>

异步加载数据并实现定制化

下面是简单例子, 其中 table-main 的初始化元素为table的id。

$('#select-game').select2(); // 初始化搜索下拉框
 
       // 表格汉化列表
  var table_lang = {
    "sProcessing": "处理中...",
    "sLengthMenu": "每页 _MENU_ 项",
    "sZeroRecords": "没有匹配结果",
    "sInfo": "当前显示第 _START_ 至 _END_ 项，共 _TOTAL_ 项。",
    "sInfoEmpty": "当前显示第 0 至 0 项，共 0 项",
    "sInfoFiltered": "(由 _MAX_ 项结果过滤)",
    "sInfoPostFix": "",
    "sSearch": "搜索:",
    "sUrl": "",
    "sEmptyTable": "表中数据为空",
    "sLoadingRecords": "载入中...",
    "sInfoThousands": ",",
    "oPaginate": {
      "sFirst": "首页",
      "sPrevious": "上页",
      "sNext": "下页",
      "sLast": "末页",
      "sJump": "跳转"
    },
    "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,   // 禁用自动调整列宽
    lengthMenu: [25, 50, 100],
    stripeClasses: ["odd", "even"], // 为奇偶行加上样式，兼容不支持CSS伪类的场合
    processing: false,   // 隐藏加载提示,自行处理
    serverSide: true,   // 启用服务器端分页
    searching: true,    // 启用原生搜索
    orderMulti: true,   // 启用多列排序
    order: [],       // 取消默认排序查询,否则复选框一列会出现小箭头
    renderer: "bootstrap", // 渲染样式：Bootstrap和jquery-ui
    pagingType: "simple_numbers", //分页样式：simple,simple_numbers,full,full_numbers
    columnDefs: [{
      "targets": 'nosort', // 列的样式名
      "orderable": false  // 包含上样式名‘nosort'的禁止排序
    }],
    ajax: function (data, callback, settings) {
      //封装请求参数
      var param = {};
      param.limit = data.length; // 页面显示记录条数，在页面显示每页显示多少项的时候
      param.start = data.start; // 开始的记录序号
      param.page = (data.start / data.length)+1; // 当前页码
      //ajax请求数据
      $.ajax({
        type: "GET",
        url: "getRecodeList",
        cache: true, // 开启缓存
        data: param, // 传入组装的参数
        dataType: "json",
        success: function (result) {
//              console.log(result);
          //setTimeout仅为测试延迟效果
          setTimeout(function () {
            //封装返回数据
            var returnData = {};
            returnData.draw = data.draw;       // 这里直接自行返回了draw计数器,应该由后台返回
            returnData.recordsTotal = result.total;  // 返回数据全部记录
            returnData.recordsFiltered = result.total;// 后台不实现过滤功能，每次查询均视作全部结果
            returnData.data = result.data;      // 返回的数据列表
            //console.log(returnData);
            // 调用DataTables提供的callback方法，代表数据已封装完成并传回DataTables进行渲染
            // 此时的数据需确保正确无误，异常判断应在执行此回调前自行处理完毕
            callback(returnData);
            cut_td($("#table-main"), 40); // 表格截断
 
          }, 200);
        }
      });
    },
    //列表表头字段
    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 = '脚本错误'; break;
            case 2: status_name = '成功'; break;
            case 3: status_name = '测试通过'; break;
            default : status_name = '未知'; break;
          }
          return status_name;
        }},
      { "data": "cast_time",
        "render" : function(data){
          if (data)
          {
            return data + 's';
          }
          else
          {
            return '废弃';
          }
        }},
      { "data": "format_created_at" },
    ]
  }).api();
