使用Moment.js和訂購插件在數據表中按日期（dd.mm.YYYY）排序

Question

我似乎在這里和Felix有幾乎相同的問題：

使用Moment.js和訂購插件在數據表中按日期（dd.mm.YYYY）排序的問題

HTML中的日期由PHP格式化： DateTime::createFromFormat('Ym-d', $date);

我考慮了正確的moment.js日期格式“ DD.MM.YYYY”。 但是，DataTables按字母順序對日期列進行排序。

這些是我的代碼段：

JavaScript：

$(document).ready(function() {
    // Setup - add a text input to each header cell for filtering
    $('#dt-requests thead th').each( function () {
        var title = $(this).text();
        $(this).html( title+'<br><input type="text" placeholder="Filter" />' );
    } );

    // Setup - register the format "tt.mm.jjjj" to detect (by moment.js) and order (by DataTables.js)
    $.fn.dataTable.moment('DD.MM.YYYY');

    // DataTable
    var table = $('#dt-requests').DataTable({
                    'paging': false, // Keine Paginierung
                    'order': [[0, 'desc']], // Sortiere die erste Spalte absteigend (=> neueste ID zuerst, somit chronologisch)
                    'columnDefs': [ // Set column definition initialisation properties
                        {   // Aktionenspalte soll für den User nicht sortierbar sein
                            'orderable': false,
                            'targets': 6
                        },
                        {   // Datum sortierbar machen 
                            'type': 'date-moment',
                            'targets': 5
                        }
                    ],
                    language: {
                        search: 'Filtern:'
                    }
    });

    // Individual column searching (text inputs).
    table.columns().eq(0).each(function(colIdx) {
        $('input', table.column(colIdx).header()).on('keyup change', function() {
            table
                .column(colIdx)
                .search(this.value)
                .draw();
        });

        // Stop the input fields triggering column sorting when clicking them.
        $('input', table.column(colIdx).header()).on('click', function(e) {
            e.stopPropagation();
        });
    });
});

有人看到有什么問題嗎？

順便說一句：因為我可以控制輸出到HTML中的日期格式，所以我寧願使用類似此處所述的傳統iDataSort參數的方法。 但是在當前的DataTables版本中似乎沒有等效的東西。

Answer 1

如果添加此：

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
    "date-moment-pre": function ( a ) {
        return ~~moment(a, "DD.MM.YYYY").format("X");
    },
    "date-moment-asc": function ( a, b ) {
        return ((a < b) ? -1 : ((a > b) ? 1 : 0));
    },
    "date-moment-desc": function ( a, b ) {
        return ((a < b) ? 1 : ((a > b) ? -1 : 0));
    }
});

並刪除此行：

$.fn.dataTable.moment('DD.MM.YYYY');

看來可行，這就是您的期望嗎？ 請檢查此JSFiddle作為工作示例，我已經更改了日期以測試訂購。
