(1)未开启服务器数据模式(即"bServerSide" : false),数据会从后台直接全部获取,然后在前台全部渲染,分页是框架自己完成的。
(2)开启服务器数据模式(即"bServerSide" : true),数据从后台查询,接着在前台将查询到的所有数据全部渲染到一页上,所以需要在后台分页后传到前台。
bServerSide的值默认为false。
建议:在数据量非常大的情况下建议在后台分页,即开启服务器数据模式。
本次以未开启服务器数据模式为例
<div class="adv-table"> <table class="display table table-bordered" id="userList"> </table> </div>
$(document).ready(function() { /* * Initialse DataTables, with no sorting on the ‘details‘ column */ var oTable = $(‘#userList‘).dataTable( { "bLengthChange": true, //允许改变每页显示的数据条数, 默认为true "bFilter": true, //开启搜索功能, 默认为true "bInfo" : true, //开启Datatables信息显示 "bPaginate" : true, //允许表格分页, 默认为true "bProcessing": true, //开启读取服务器数据时显示正在加载中 //"bServerSide": true, //开启服务器模式 "iDisplayLength": 5,//每页显示15条数据 // Ajax地址 "sAjaxSource": contextPath + "/user/getUserList?time=" + new Date().getTime(), "sAjaxDataProp" : "aaData", "aoColumnDefs": [ //列定义配置数组 { "bSortable": true, //开启或关闭某列的排序 "aTargets": [ 0 ] //指定一个特定的列 } ], "aaSorting": [[0, ‘asc‘]], // 第1列,增序 "aLengthMenu": [ [5, 15, 20, -1], [5, 15, 20, "All"] ], //改变每页显示条数列表的选项 //配置列要显示的数据 "aoColumns": [ { "mDataProp" : "id", "sTitle" : "<input type=‘checkbox‘ name=‘allbox‘ id=‘allbox‘ onclick=‘check();‘ />", "sDefaultContent" : "", "bSortable" : false, "sClass" : "center", "mRender" : function(data, display, row) { return "<input type=‘checkbox‘ id=‘"+data+"‘ name=‘idList‘ value=‘"+data+"‘/>"; } }, { "sTitle" : "ID", //显示的列名 "mDataProp": "id", //对应的数据中的字段名 "sDefaultContent" : "", "sClass" : "center" }, { "sTitle" : "Name", "mDataProp": "name", "sDefaultContent" : "", "sClass" : "center" }, { "sTitle" : "Age", "mDataProp": "age", "sDefaultContent" : "", "sClass" : "center" }, { "sTitle" : "Update Time", "mDataProp": "updateTime", "sDefaultContent" : "", "sClass" : "center", "mRender" : function(data, display, row) { //将从数据库中查到的时间戳格式化 return new Date(data).Format("yyyy-MM-dd hh:mm:ss"); } }, { "sTitle" : "Operate", "mDataProp": ‘‘, "sDefaultContent" : ‘<i class="fa fa-plus-square"><i class="fa fa-edit"></i><i class="fa fa-trash-o"></i>‘, //设置该列字段的值 "sClass" : "center" } ], "oLanguage": { //国际化配置 "sProcessing" : "正在获取数据,请稍后...", "sLengthMenu" : "显示 _MENU_ 条", "sZeroRecords" : "没有您要搜索的内容", "sInfo" : "从 _START_ 到 _END_ 条记录 总记录数为 _TOTAL_ 条", "sInfoEmpty" : "记录数为0", "sInfoFiltered" : "(全部记录数 _MAX_ 条)", "sInfoPostFix" : "", "sSearch" : "搜索", "sUrl" : "", "oPaginate": { "sFirst" : "第一页", "sPrevious" : "上一页", "sNext" : "下一页", "sLast" : "最后一页" } } }); /* Add event listener for opening and closing details * Note that the indicator for showing which row is open is not controlled by DataTables, * rather it is done here */ // $(document).on(‘click‘,‘#hidden-table-info tbody td img‘,function () { // var nTr = $(this).parents(‘tr‘)[0]; // if ( oTable.fnIsOpen(nTr) ) // { // /* This row is already open - close it */ // this.src = "images/details_open.png"; // oTable.fnClose( nTr ); // } // else // { // /* Open this row */ // this.src = "images/details_close.png"; // oTable.fnOpen( nTr, fnFormatDetails(oTable, nTr), ‘details‘ ); // } // } ); } ); // 日期格式转换 Date.prototype.Format = function (fmt) { //author: meizz var o = { "M+": this.getMonth() + 1, //月份 "d+": this.getDate(), //日 "h+": this.getHours(), //小时 "m+": this.getMinutes(), //分 "s+": this.getSeconds(), //秒 "q+": Math.floor((this.getMonth() + 3) / 3), //季度 "S": this.getMilliseconds() //毫秒 }; if (/(y+)/.test(fmt)) { fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length)); } for (var k in o) { if (new RegExp("(" + k + ")").test(fmt)) { fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ?
