Jquery数据表：j未定义

这是我第一次看到此错误，但我找不到解决方案：

var request = $.ajax({
        type: "POST",
        url: "../php/admin_function.php",
        data: {
            act: "retrive_faq"
        },
        dataType: "json",
        success: function (a) {
            if ("ret" == a.response || "empty" == a.response) {
                if ("ret" == a.response) {
                    var b = a.faq.length;
                    for (i = 0; i < b; i++) {
                        a.faq[i].action = '<div class="btn-group"><button class="btn btn-info editdep" value="' + a.faq[i].id + '"><i class="icon-edit"></i></button><button class="btn btn-danger remdep" value="' + a.faq[i].id + '"><i class="icon-remove"></i></button></div>'
                    }
                }
                $("#loading").remove();
                $("#faqtable").dataTable({
                    sDom: "<<'span6'l><'span6'f>r>t<<'span6'i><'span6'p>>",
                    sWrapper: "dataTables_wrapper form-inline",
                    bProcessing: !0,
                    aaData: a.faq,
                    oLanguage: {sEmptyTable: "No FAQs"},
                    aoColumns: [
                        {sTitle: "Id",mDataProp: "id",sWidth: "60px"}, 
                        {sTitle: "Question",mDataProp: "question"}, 
                        {sTitle: "Postion",mDataProp: "position",sWidth: "50px"}, 
                        {sTitle: "Active",mDataProp: "active",sWidth: "60px"}, 
                        {sTitle: "Rate",mDataProp: "rate",sWidth: "40px"}, 
                        {sTitle: "Toogle",mDataProp: "action",bSortable: !1,bSearchable: !1,sWidth: "60px"}
                    ]
                });
            } else {
                noty({text: a[0],type: "error",timeout: 9E3})
            }
        }
    });
    request.fail(function (a, b) {noty({text: b,type: "error",timeout: 9E3})});

我做错了什么？

如果在DataTable.js中出现这种错误

TypeError: j[(f - d)] is undefined



L(jQuery)})(window,document);

始终寻找最佳答案

 "aoColumns": [{"bSortable": false, "mRender": checkbox}, {"mRender": fld}, null, null, null, {"mRender": row_status}, {"mRender": currencyFormat}, {"bSortable": false}],

这是用于显示记录的每列的实际计数

{"bSortable": false, "mRender": checkbox}

这是一个街区换一个街区

如果您有10个，那么请确保您也有10个以上块

TypeDataTables中的错误通常意味着表格html无效，表格的html在哪里？现在我删除该行，然后再次插入更新的行，该表只是带有id和一些类的表标记。当您缺少HTML中正确的

和

标记时，可能会发生这种情况。

{"bSortable": false, "mRender": checkbox}
