Question

拥有数据表并使用向下钻取行。顶行填充数据，但向下钻取到附加行的链接包含一个未定义的对象，我就卡在那里。

任何帮助都会非常感激。 oData.code（undefinded）/ oData本身将返回linq查询中的所有内容，但是当我开始使用oData.etc时...对象变得未定义。即使在click事件中，我也尝试访问oData并将其放在第二个TD行中，并且它也是未定义的。

function fnFormatDetails(oTable, nTr) 
{
    var oData = oTable.fnGetData(nTr);

    var sOut =
        '<div>' +
        '<table>' +
        '<tr><td> '+oData.code+' </td><td>  </td><td> </td><td>  </td><td>  </td><td>  </td><td>  </td></tr>'
        '</table>' +
        '</div>';                           

        return sOut;
} //end fnFormatDetails function


$(document).ready(function () 
{
    var anOpen = [];
    var oTable = $('#VADataTable').dataTable(
    {
        "sDom": 'T<"clear">lfrtip',
        "oTableTools":
        {
            "sSwfPath": "/swf/copy_csv_xls_pdf.swf"

                $('td:eq(0)', nRow).html("+").addClass('control');
            }
            return nRow;
        }, //ends fnRowCallback

        "aoColumns":
        [
            { "sName": "code", "sTitle": "Code" },
            { "sName": "code" },

            { "sName": "data" }
        ]
    });

    $('#VADataTable td.control').live('click', function () 
    {
        var nTr = this.parentNode;
        var i = $.inArray(nTr, anOpen);

        if (i === -1) 
        {
            $('td').attr('+');
            var nDetailsRow = oTable.fnOpen(nTr, fnFormatDetails(oTable, nTr), 'details');
            $('div', nDetailsRow).slideDown();
            anOpen.push(nTr);
        } //end if
        else

                anOpen.splice(i, 1);
            }); //ends slideUp
        } //ends else

我相信只需在“aoColumns”中添加“mData”属性，即数据库表的字段名称，并在“fnRowCallback”中添加您必须将“aData [0]”替换为“aData ['code']”，如下一个示例所示：

"fnRowCallback": function (nRow, aData) 
    {
        if (aData['code'] == "") 
        {
            $('td:eq(0)', nRow).html("+").addClass('control');
        }
        return nRow;
    }, //ends fnRowCallback

    "aoColumns":
    [
        { "mData" : "code", "sName": "code", "sTitle": "Code" },
        { "mData" : "code", "sName": "code" },
        { "mData" : "data", "sName": "data" },
        { "mData" : "data", "sName": "data" },
        { "mData" : "data", "sName": "data" },
        { "mData" : "data", "sName": "data" },
        { "mData" : "data", "sName": "data" }
    ]
