无法指定datatables javascript的默认列排序

我需要按页面加载上的特定列进行排序，在这种情况下，让它以“RecordDate”降序显示初始结果

问题是，我相信服务器端正在阻止任何排序规范，我在下面所做的任何修改都不会加载结果（分类[[列数，名称，描述]]等）

我可以编写一个特殊函数来强制此列排序吗？在修改存储过程或另一个cs文件之前，是否可以在此处处理此问题

function GetRecords( DTO ) {
var grpid = ApplyGroupingOnTable();
console.log( grpid );
oTable = $( "#SearchTable" ).dataTable( {
    "oLanguage": {
        "sZeroRecords": "No records to display"//,
        //"sSearch": "Search on UserName"
    },
    "aLengthMenu": [[10, 25, 50, 100, 150, 250, 500], [10, 25, 50, 100, 150, 250, 500]],

        { "mData": "ViewID", "sClass": "alternatingCenterAlign", fnRender: CreateCaseViewerButton, "bSortable": false, "bSearchable": false, "sWidth": "18px" },

        aoData.push( { "name": "iSearch", "value": JSON.stringify( DTO ) } );
        aoData.push( { "name": "iId", "value": cliid } );
        aoData.push( { "name": "iOrder", "value": grpid } );
    },
    "fnDrawCallback": function ( oSettings ) {
        if ( grpid ) FinalGrouping( oSettings, grpid );
        $( ".overflow" ).each( function () { $( this ).attr( 'title', $( this ).text() ); } );
        $( '#tablediv select' ).chosen();
    },
    "fnServerData": function ( sSource, aoData, fnCallback ) {
        $( '.grid-loading' ).show();
        $.ajax( {
            dataType: 'json',
            contentType: "application/json; charset=utf-8",
            type: "GET",
            url: sSource,
            data: aoData,
            cache: false,
            success: function ( msg ) {
                if ( msg.Exception != undefined ) {
                    alert( msg.Exception );
                    $( '.grid-loading' ).hide();
                    return false;
                }
                lastId = ( msg.aaData.length > 0 ) ? msg.aaData[msg.aaData.length - 1][0] : 0;
                fnCallback( msg );
                $( '.grid-loading' ).hide();
            }
        } ); //End Ajax Call
    }
} );
}

假设您可以访问dataTable的数据数组，并且其形式如下：

var array = [ 
               { name: "somename", value: "somevalue" },
               { name: "somename2", value: "somevalue2" }
           ];

您可以根据以下值执行简单的降序排序：

array.sort(SimpleCompareDescOnValue);

鉴于功能：

function SimpleCompareDescOnValue(a, b) {
        // Use caution so as not to define 'undefined'.  It's not a great practice but it works.
        var c = a.length != undefined ? Math.max.apply(Math, a.map(function (o) { return o.value; })) : a.value;
        var d = b.length != undefined ? Math.max.apply(Math, b.map(function (o) { return o.value; })) : b.value;

        if (c > d)
            return -1;
        if (c < d)
            return 1;
        return 0;
    }

函数SimpleComparedSconValue（a，b）{
//小心不要定义“未定义”。这不是一个很好的实践，但它是有效的。
var c=a.length！=undefined？Math.max.apply（Math，a.map（函数（o）{return o.value；}））：a.value；
var d=b.length！=undefined？Math.max.apply（Math，b.map（函数（o）{return o.value；}））：b.value；
如果（c>d）
返回-1；
if（c

不确定这是否对你有帮助。我从未使用过dataTable库（尽管它看起来很酷），但我必须假设您可以在从服务器提取数据后访问数据，并且它只在某种程度上存储在数组中是有意义的。

感谢您的响应。最后，我不得不将aaSorting属性修改为datatables.Jquery中的特定列desc。并在该栏上注明“日期”。按日期排序desc似乎让事情慢了一点，但这是另一个讨论！
