这次给大家带来datatable怎样实现异步加载,datatable实现异步加载的注意事项有哪些,下面就是实战案例,一起来看一下。
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();
后台数据返回格式
{ "total": 234, "per_page": "25", "current_page": 1, "last_page": 10, "next_page_url": "http://local.dgc_sdkops.com/monitor/log_pack/getRecodeList?page=2", "prev_page_url": null, "from": 1, "to": 25, "data": [ { "id": 128, "user_id": 1, "task_id": "package_128_113", "channel_version_id": 128, "game_version_id": 113, "extend_id": 0, "type": "pack", "status": 2, "remark": "", "cast_time": 93475, "created_at": "1500365068", "updated_at": "1500458543", "user_name": "admin", "format_created_at": "2017-07-18 16:04:28", "format_updated_at": "2017-07-18 16:04:28", "game": "x", "channel": "y", "game_id": 11290, "channel_id": 67 }, { "id": 240, "user_id": 1, "task_id": "package_128_113", "channel_version_id": 128, "game_version_id": 113, "extend_id": 0, "type": "pack", "status": 0, "remark": "", "cast_time": 0, "created_at": "1500458454", "updated_at": "1500458454", "user_name": "admin", "format_created_at": "2017-07-19 18:00:54", "format_updated_at": "2017-07-19 18:00:54", "game": "x", "channel": "y", "game_id": 11290, "channel_id": 67 } ] }
