九天 ，datatables列和跳转页面的配置，Ajax请求

使用datatables 隐藏列的方法与注意事项

var AIGroup_table = $('#AIGroup_table').DataTable({
        bAutoWidth: false,
        sDom: DataTableDom,
        oLanguage: DataTableLanguage,
        iDisplayLength: 2,
        ordering: false,
        bLengthChange: true,
        bInfo: true,
        bPaginate: true,
        bProcessing: true,
        bServerSide: true,
        // bStateSave: true,  隐藏列，需要把这个去掉
        bFilter: false,

　　　　　　//可以设置隐藏列，
          columnDefs: [
          { "visible": false, "targets": 2 },

        ],

        sAjaxSource: '/aiGroupData',
        fnServerData: getDataFromServerSideForDataTable,
        columns: [
            {
                 '10%',
                mData: "id",
                // bSortable: false,
                sClass: "text-center",
                // "visible": false,
                mRender: function (data, type, row) {
                    return '<input type="checkbox"  name="business" style="opacity: 2; position: static; margin-top: 0px;" value="' + data + '">'
                }
            },
            {
                 '10%',
                mData: "name_s_30",
                bSortable: false,
                sClass: "text-center",
                mRender: function (data, type, row) {
                    return data
                }
            },
         .....


        ],
        //设置你的跳转页面的显示按键
        //AIGroup_table_paginate，是页面的div---ID标签
        fnDrawCallback: function (table) {
            $("#AIGroup_table_paginate").append("  到第 <input style='height:28px;line-height:28px;40px;' class='margin text-center' id='changePage' type='text'> 页  <a class='btn btn-default shiny' style='margin-bottom:5px' href='javascript:void(0);' id='dataTable-btn'>确认</a>");
            var oTable = $("#AIGroup_table").dataTable();
            $('#dataTable-btn').click(function (e) {
                if ($("#changePage").val() && $("#changePage").val() > 0) {
                    var redirectpage = $("#changePage").val() - 1;
                } else {
                    var redirectpage = 0;
                }
                oTable.fnPageChange(redirectpage);
            });
        },


    });
