datatable分页指南--前台分页和后台分页

本文主要是介绍datatable分页指南--前台分页和后台分页，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、介绍

Datatables是一款jquery表格插件。它是一个高度灵活的工具，可以将任何HTML表格添加高级的交互功能。

• 分页，即时搜索和排序
• 几乎支持任何数据源：DOM， javascript， Ajax 和 服务器处理
• 支持不同主题 DataTables, jQuery UI, Bootstrap, Foundation
• 各式各样的扩展: Editor, TableTools, FixedColumns ……
• 丰富多样的option和强大的API
• 支持国际化
• 超过2900+个单元测试

二、引入

<link rel="stylesheet" type="text/css" href="/DataTables-1.10.7/css/jquery.dataTables.css"><!-- jQuery -->
<script type="text/javascript" charset="utf8" src="/DataTables-1.10.0/js/jquery.js"></script><!-- DataTables -->
<script type="text/javascript" charset="utf8" src="/DataTables-1.10.7/js/jquery.dataTables.js"></script>

三、html

 <table class="table table-bordered table-hover" id="bigDataList"><thead><tr><th>用户id</th><th>主叫</th><th>识别码</th><th>区域id</th><th>服务类型</th><th>服务组</th><th>位置区码</th><th>GPRS节点</th><th>分配记数</th><th>协议类型</th><th>开始时间</th><th>结束时间</th></tr></thead><tbody></tbody></table>

四、js代码

 var table1;//dataTable初始化对象function bigDataTable(queryData){table1= $('#bigDataList').DataTable({"paging": true,"lengthChange": true,"searching": true,"ordering": true,"aaSorting" : [[0, "asc"]], //默认的排序方式，第1列，升序排列"info": true,"autoWidth": false,"destroy":true,"processing":true,"scrollX": true,   //水平新增滚动轴
//          "serverSide":true,    //true代表后台处理分页，false代表前台处理分页"aLengthMenu":[10,15,20],"PaginationType" : "full_numbers", //详细分页组，可以支持直接跳转到某页//当处理大数据时，延迟渲染数据，有效提高Datatables处理能力"deferRender": true,"ajax":{url:"getJson_BigData_queryDataByParams",dataSrc:function(data){if(data.callbackCount==null){data.callbackCount=0;}//抛出异常if(data.sqlException){alert(data.sqlException);}//查询结束取消按钮不可用$("#queryDataByParams").removeAttr("disabled");return data.dataList;             //自定义数据源，默认为data},     //dataSrc相当于success，在datatable里面不能用success方法，会覆盖datatable内部回调方法type:"post",data:queryData},columns:[{ data: 'user_ip' },{ data: 'calling'},{ data: 'imei' },{ data: 'cell_id'},{ data: 'service_type' },{ data: 'service_group'},{ data: 'lac' },{ data: 'sgsn'},{ data: 'assignment_count' },{ data: 'proto_type'},{ data: 'start_time' },{ data: 'end_time'},],/*是否开启主题*/"bJQueryUI": true,"oLanguage": {    // 语言设置"sLengthMenu": "每页显示 _MENU_ 条记录","sZeroRecords": "抱歉， 没有找到","sInfo": "从 _START_ 到 _END_ /共 _TOTAL_ 条数据","sInfoEmpty": "没有数据","sInfoFiltered": "(从 _MAX_ 条数据中检索)","sZeroRecords": "没有检索到数据","sSearch": "检索:","oPaginate": {"sFirst": "首页","sPrevious": "前一页","sNext": "后一页","sLast": "尾页"}},});}

点击请求ajax，返回渲染数据：

 //点击查询$("#queryDataByParams").on("click",function() {var reg = new RegExp("^[0-9]*$");var startTime=$("#searchDateRange").val().substring(0,19).replace(/-/g, '/');var endTime=$("#searchDateRange").val().substring(22,41).replace(/-/g, '/');var date1=new Date(startTime);  //开始时间var date2=new Date(endTime);    //结束时间var date3=date2.getTime()-date1.getTime()  //时间差的毫秒数if(date3>60*60*24*1000){alert("开始时间与结束时间间隔大于24小时！");return false;}if(!$("#searchDateRange").val() || $("#searchDateRange").val()=="填写时间段"){alert("时间区段不能为空！");return false;}if(!$("#calling").val() && !reg.test($("#calling").val())){alert("请输入全数字!");}//查询时候设置按钮不可用$("#queryDataByParams").attr("disabled", true);var queryData={"startseg":$("#searchDateRange").val(),"callseg":$("#calling").val(),"identifiCode":$("#identifiCode").val(),"areaId":$("#areaId").val(),"serviceType":$("#serviceType").val(),"serviceGroup":$("#serviceGroup").val(),"areaCode":$("#areaCode").val(),"gprsNode":$("#gprsNode").val(),"distritNum":$("#distritNum").val(),"protocolType":$("#protocolType").val()};if(table1!=null || table1 !=undefined){//        dataTable初始化之后不能再设值，需要销毁重新定义，(数据量大时不适用)
//            table1.destroy();
//            bigDataTable(queryData);//              var src={
//                url:"getJson_BigData_queryDataByParams",
//                dataSrc :"dataList",      //自定义数据源，默认为data
//                type:"post",
//                data:{"test":$("#protocolType").val()}
//              };//            table1.fnSettings().ajax=src; //ajax访问数据
//            table1.fnPageChange(0,true);  //分页的页数从0开始table1.settings()[0].ajax.data=queryData;table1.ajax.reload();}else{bigDataTable(queryData);}});

上面是前台分页，如果要做后台分业，当然最好就是用后台分页：

1.修改datatable初始化属性，新增

"serverSide":true,    //true代表后台处理分页，false代表前台处理分页

2.后台即可获取到每页数据，当前页参数

	private int length;private int start:public int getLength(){return length;}public void setLength(int length){this.length = length;}public int getStart(){return start;}public void setStart(int start){this.start = start;}

我的后台是用struts2写的，其他的也可以用request里面获取，这个值初始化设置之后会一起返回给后端的，然后后端操作数据库的时候，就可以根据这两个参数就行真分页了。

public String dataPaging(){resultJson = new HashMap<String,Object>();searchItem = getRequest().getParameter("extra_search");List<Log> list = new ArrayList<Log>();list = logService.queryForPaging(start,length,searchItem);int count = logService.queryForPagingSize(searchItem);resultJson.put("draw", Integer.toString(draw));resultJson.put("recordsTotal", Integer.toString(count));resultJson.put("recordsFiltered",  Integer.toString(count));resultJson.put("data", list);return "success";}

public List<T> queryForPaging(int start,int length,String query) {Criteria cri = getSession().createCriteria(this.persistentClass);cri.addOrder(Order.desc("id")).setFirstResult(start).setMaxResults(length);if(query != null && !"".equals(query)){cri.add(Restrictions.like("username", query, MatchMode.ANYWHERE));}List<T> list = cri.list();return list;}

前后台数据交互：

前台格式：

 <table id="activityList" class="table table-bordered table-hover"><thead><tr><th width="10%">ID</th><th width="15%">店铺名称</th><th width="15%">优惠活动</th><th width="15%">开始时间</th><th width="15%">结束时间</th><th width="15%">操作</th></tr></thead><tbody></tbody></table>

 columns:[{ data: 'id' },{ data: 'storeInfo.realName'},{ data: 'content' },{ data: 'startTime',"render": function ( data, type, full, meta ) {var dataStr = Date.parse(data);return new Date(dataStr).Format("yyyy-MM-dd hh:mm:ss");}},{ data: 'endTime',"render": function ( data, type, full, meta ) {var dataStr = Date.parse(data);return new Date(dataStr).Format("yyyy-MM-dd hh:mm:ss");}},{data:'id',"render": function ( data, type, full, meta ) {var edithtml ="<button class=\"btn btn-info\" type=\"button\" οnclick='editorActivity()'>编辑</button> "+"<button class=\"btn btn-info\" type=\"button\" οnclick='deleteActivity()'>删除</button>"return edithtml;}}],

日期格式化：
 Date.prototype.Format = function (fmt) { //author: meizzvar 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) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));return fmt;}

后台返回的json数据：
{"resultList": [{"content": "元旦大促销活动","endTime": "2016-01-03T22:00:00","id": 1,"startTime": "2016-01-01T08
:00:00","storeInfo": {"buildingId": 3,"buildingName": "一号楼","floorId": 4,"floorName": "一层","id": 1,"realName": "KFC","siteId": 2,"siteName": "河西万达","storeId": 7,"storeName": "Z1","zoneId": 1,"zoneName": "万达企业"}},{"content": "手撕汉堡，新品上市，买一送一","endTime": "2015-12-30T14:43:38","id": 2,"startTime": "2015-12-29T14:43:34","storeInfo": {"buildingId": 3,"buildingName": "一号楼","floorId": 4,"floorName": "一层","id": 1,"realName": "KFC","siteId": 2,"siteName": "河西万达","storeId": 7,"storeName": "Z1","zoneId": 1,"zoneName": "万达企业"}},{"content": "麻麻黑，免费吃，只
要你能吃得完，随便吃","endTime": "2016-02-15T14:45:05","id": 3,"startTime": "2016-02-01T14:44:53","storeInfo": {"buildingId": 3,"buildingName": "一号楼","floorId": 4,"floorName": "一层","id": 1,"realName": "KFC","siteId": 2,"siteName": "
河西万达","storeId": 7,"storeName": "Z1","zoneId": 1,"zoneName": "万达企业"}}]
}
