datatable表格框架服務器端分頁查詢設置

js代碼以下： $('#mytable').dataTable( { "bServerSide": true, //開啓服務器模式，使用服務器端處理配置datatable。注意：sAjaxSource參數也必須被給予爲了給datatable源代碼來獲取所需的數據對於每一個畫。 這個翻譯有點彆扭。開啓此模式後，你對datatables的每一個操做 每頁顯示多少條記錄、下一頁、上一頁、排序（表頭）、搜索，這些都會傳給服務器相應的值。
            "sAjaxSource": "ajax.php", //給服務器發請求的url
            "aoColumns": [ //這個屬性下的設置會應用到全部列，按順序，沒有是空
                {"sDefaultContent": ''},//checkbox column 至關於佔位符，等待填充。也能夠指定值如 {"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 表示給本列加class
            ],
            "aoColumnDefs": [//和aoColums相似，但他能夠給指定列賦予屬性
                {"bSortable": false, "aTargets": [0,7,9]},  //這句話意思是第7,9列（從0開始算）不排序
 ],
            "aaSorting": [[1, "asc"]], //默認排序
