复杂标题的排序和搜索问题

Question

我有以下表格标记：

<table class="table listagem-dados filtering-col table-bordered table-striped responsive" cellspacing="0" width="100%" summary="Esta tabela exibe os perfis de usuários existentes e os relaciona com tipos de usuário, tipos de perfil e seus respectivos status.">

        <th id="coluna1">Perfil</th>
        <th id="coluna2">Usuário</th>
        <th id="coluna3">Tipo Perfil</th>
        <th id="coluna4">Status</th>
    </tr>
    <tr class="filterrow">
        <th><i class="material-icons md">&#xE8B6;</i></th>
        <th class="input-filter"><input type="text" class="form-control tchatchaca" placeholder="Buscar por Perfil"></th>
        <th class="select-filter"><select class="form-control" placeholder="Buscar por Usuário">

            <option value="Governo">Governo</option>

     <td headers="linha2 coluna3">Administrativo</td>
     <td headers="linha2 coluna4">Bloqueado</td>
    </tr>
</tbody>
</table>

如您所见，在此表中，标题中有 2 行，其中第一行用于标题和排序，第二行用于过滤。一些过滤器将<input type="text">通过 a发生，而其他过滤器将通过 a 发生<select>。

我使用以下代码初始化了数据表。

$(document).ready(function() {
     // DataTable
    var table = $('table').DataTable({
        "language": {
            "lengthMenu": "Mostrar _MENU_ registros por página",
            "zeroRecords": "Nenhum registro encontrado",
            "info": "Showing page _PAGE_ of _PAGES_",
            "infoEmpty": "No records available",
            "infoFiltered": "(filtered from _MAX_ total records)"
        },
    });
    // Apply the search
    table.columns( '.input-filter' ).every( function () {
        var that = this;

        $( 'input', this.header() ).on( 'keyup change', function () {
            if ( that.search() !== this.value ) {
                that
                    .search( this.value )
                    .draw();
            }
        } );
    } );
    // Apply the search
    table.columns( '.select-filter' ).every( function () {
        var that = this;

        $( 'select', this.header() ).on( 'change', function () {
            if ( that.search() !== this.value ) {
                that
                    .search( this.value )
                    .draw();

            } else if ( that.search() !== "" ) {
                that
                    .draw();
            }
        } );
    } );
 } );

但默认情况下，DataTables 在标题的最后/第二行设置排序。然后我把它"bSortCellsTop": true放在初始化中：

// DataTable
var table = $('table').DataTable({
    "language": {
        "lengthMenu": "Mostrar _MENU_ registros por página",
        "zeroRecords": "Nenhum registro encontrado",
        "info": "Showing page _PAGE_ of _PAGES_",
        "infoEmpty": "No records available",
        "infoFiltered": "(filtered from _MAX_ total records)"
    },
    "bSortCellsTop": true
});

并且排序现在按预期位于第一行。但是搜索根本不起作用。我输入了输入，响应什么也没有。在 de 控制台日志中没有错误。我已经尽力了。我更改了类，禁用了其他依赖项，获得了最新版本的数据表，更改了标签的位置和许多其他内容。

原因

看来，使用复杂的标题，您无法访问未用于排序的标题列columns()。

解决方案

重写您的代码如下：

// Apply the search
$.each($('.input-filter', table.table().header()), function () {
    var column = table.column($(this).index());

    $( 'input', this).on( 'keyup change', function () {
        if ( column.search() !== this.value ) {
            column
                .search( this.value )
                .draw();
        }
    } );
} );

// Apply the search
$.each($('.select-filter', table.table().header()), function () {
    var column = table.column($(this).index());

    $( 'select', this).on( 'change', function () {
        if ( column.search() !== this.value ) {
            column
                .search( this.value )
                .draw();

        } else if ( column.search() !== "" ) {
            column
                .draw();
        }
    } );
} );

笔记

• 用于"orderCellsTop": true代替bSortCellsTopDataTables 1.10+
• 最后一个选择框选项“Bloqueado”还显示“Desbloqueado”。
