这个是ajax请求列表，成功则渲染，不成功没有任何反应了，比如登陆失效

   function initDatatable() {
        datatable = $('.datatable').DataTable({
            "dom": '<"toolbar">frtip',
            "searching":false,
            "processing": false,
            "serverSide": true,
            "select": true,
            "ordering": true,
            "language": {
                "url": "${base}/assets/plugins/datatables/cn.json"
            },
            "preDrawCallback": function () {
                sublime.showLoadingbar($(".main-content"));
            },
            "drawCallback": function () {
                sublime.closeLoadingbar($(".main-content"));
            },
            "ajax": {
                "url": "${base}/platform/sys/systask/data",
                "type": "post",
                "data": function (d) {
                },
            },
            "columns": [
                    {"data": "name", "bSortable": true},
                    {"data": "jobClass", "bSortable": true},
                    {"data": "cron", "bSortable": true},
                    {"data": "disabled", "bSortable": true},

                    {"data": "exeResult", "bSortable": true}
            ],
        });
        datatable.on('click', 'tr', function () {
            $(this).toggleClass('selected');
        });
        $("#searchBtn").on('click', function () {
            datatable.ajax.reload();
        });
    }
