数据表/YADCF 和过滤器排序顺序

Question

我正在使用数据表和 yadcf 按月份和工作日进行过滤，但无法对 select 列表进行正确排序。

<table id="myTable" class="table table-striped">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>Month</th>
<th>Weekday</th>
</tr>
</thead>
</table>

var myData = [
    {"Id":1,"Name":"Test 1","Month":{"Id":5,"Label":"May"},"Weekday":{"Id":3,"Label":"Tuesday"}},
    {"Id":2,"Name":"Test 2","Month":{"Id":5,"Label":"May"},"Weekday":{"Id":3,"Label":"Tuesday"}}
    ...
];

$(function () {
    var Table = $('#myTable').DataTable({
        'data': myData,
        "columns" : [
            { "targets": 0, "data" : "Id" },
            { "targets": 1, "data" : "Name" },
            { "targets": 2, "data": function ( data, type, val, meta ) {
                if (type === 'display') {
                    return  data.Month.Label;

                }else if (type === 'filter') {
                    return data.Month.Label;
                }
                // 'sort', 'type' and undefined all just use the integer
                return data.Month.Id;
            } },
            { "targets": 3, "data": function ( data, type, val, meta ) {
                if (type === 'display') {
                    return  data.Weekday.Label;

                }else if (type === 'filter') {
                    return data.Weekday.Label;
                }
                // 'sort', 'type' and undefined all just use the integer
                return data.Weekday.Id;
            } }
        ]
    });

    yadcf.init(Table, [
        {
            column_number : 2, 
            filter_type: 'select',
            filter_match_mode: 'exact', 
            style_class: 'form-control'
        },
        {
            column_number : 3, 
            filter_type: 'select',
            filter_match_mode: 'exact', 
            style_class: 'form-control'
        }
    ]);
} );

我如何订购这些过滤器，以便它们在一月、二月、三月和周一、周二、周三等工作日订购？

如果我为过滤器添加自定义排序函数并为过滤器添加 return data.Month.Id ，排序将是正确的，但月份编号是显示在过滤器中而不是它的名称。

感谢任何帮助，因为它让我发疯，谢谢！

你应该使用 sort_as: 'custom', sort_as_custom_func: monthSort 并实现你自己的排序功能，这里有一个快速的方法：

$(function () {
    var Table = $('#myTable').DataTable({
        'data': myData,
        "columns" : [
            { "data" : "Id" },
            { "data" : "Name" },
            { "data" : "Month.Label" },
            { "data" : "Weekday.Label" }
        ]
    });

    yadcf.init(Table, [
        {
            column_number : 2, 
            filter_type: 'select',
            filter_match_mode: 'exact', 
            style_class: 'form-control',
            sort_as: 'custom',
            sort_as_custom_func: monthSort
        },
        {
            column_number : 3, 
            filter_type: 'select',
            filter_match_mode: 'exact', 
            style_class: 'form-control'
        }
    ]);
  
  function monthSort(a, b){
    var months = ["January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December"];
         return months.indexOf(a) - months.indexOf(b);}
} );
