篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了datatable表格框架服务器端分页查询设置相关的知识,希望对你有一定的参考价值。

js代码如下:
$(‘#mytable‘).dataTable(
        {
            "bServerSide": true, //开启服务器模式,使用服务器端处理配置datatable。注意:sAjaxSource参数也必须被给予为了给datatable源代码来获取所需的数据对于每个画。 这个翻译有点别扭。开启此模式后,你对datatables的每个操作 每页显示多少条记录、下一页、上一页、排序(表头)、搜索,这些都会传给服务器相应的值。
            "sAjaxSource": "ajax.php", //给服务器发请求的url
            "aoColumns": [ //这个属性下的设置会应用到所有列,按顺序没有是空
                {"sDefaultContent": ‘‘},//checkbox column 相当于占位符,等待填充。也可以指定值如 {"mData": ‘ip‘}
                {"sDefaultContent": ‘‘},//ip column
                {"sDefaultContent": ‘‘},//nip column
                {"sDefaultContent": ‘‘},//role column
                {"sDefaultContent": ‘‘},//gamenserver column
                {"sDefaultContent": ‘‘},//serverid column
                {"sDefaultContent": ‘‘},//status column
                {"sDefaultContent": ‘‘},//remark column
                {"sDefaultContent": ‘‘},//ctime column
                {"sDefaultContent": ‘‘, "sClass": "action"},//sClass 表示给本列加class
            ],
            "aoColumnDefs": [//和aoColums类似,但他可以给指定列附近爱属性
                {"bSortable": false, "aTargets": [0,7,9]},  //这句话意思是第7,9列(从0开始算)不排序

            ],
            "aaSorting": [[1, "asc"]], //默认排序

            "fnRowCallback": function(nRow, aData, iDisplayIndex) {// 给各列填充内容
                $(‘td:eq(0)‘, nRow).html(‘<label><input type="checkbox" id="hids[]" value="‘+aData.id+‘-‘+aData.status+‘" name="hids[]"></label>‘);
