我希望this demo使用过滤器,而不是删除其子项具有要过滤的数据的条目。

例如。在示例中,如果您过滤5407,则Airi Satou不会被删除,甚至子数据也会被扩展。

HTML和JS

/* Formatting function for row details - modify as you need */
function format ( d ) {
    // `d` is the original data object for the row
    return '<div class="slider">'+
        '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
            '<tr>'+
                '<td>Full name:</td>'+
                '<td>'+d.name+'</td>'+
            '</tr>'+
            '<tr>'+
                '<td>Extension number:</td>'+
                '<td>'+d.extn+'</td>'+
            '</tr>'+
            '<tr>'+
                '<td>Extra info:</td>'+
                '<td>And any further details here (images etc)...</td>'+
            '</tr>'+
        '</table>'+
    '</div>';
}

$(document).ready(function() {
    var table = $('#example').DataTable( {
        "ajax": "/examples/ajax/data/objects.txt",
        "columns": [
            {
                "class":          'details-control',
                "orderable":      false,
                "data":           null,
                "defaultContent": ''
            },
            { "data": "name" },
            { "data": "position" },
            { "data": "office" },
            { "data": "salary" }
        ],
        "order": [[1, 'asc']]
    } );

    // Add event listener for opening and closing details
    $('#example tbody').on('click', 'td.details-control', function () {
        var tr = $(this).closest('tr');
        var row = table.row( tr );

        if ( row.child.isShown() ) {
            // This row is already open - close it
            $('div.slider', row.child()).slideUp( function () {
                row.child.hide();
                tr.removeClass('shown');
            } );
        }
        else {
            // Open this row
            row.child( format(row.data()), 'no-padding' ).show();
            tr.addClass('shown');

            $('div.slider', row.child()).slideDown();
        }
    } );
} );


的CSS

td.details-control {
    background: url('/examples/resources/details_open.png') no-repeat center center;
    cursor: pointer;
}

tr.shown td.details-control {
    background: url('/examples/resources/details_close.png') no-repeat center center;
}

div.slider {
    display: none;
}

table.dataTable tbody td.no-padding {
    padding: 0;
}

最佳答案




为了让jQuery DataTables搜索子行,您需要将子行中显示的数据作为隐藏列添加到主表中。

例如,您可以使用extn选项为columns.visible数据属性添加隐藏列,如下所示:

JavaScript:

    "columns": [
        {
            "class":          'details-control',
            "orderable":      false,
            "data":           null,
            "defaultContent": ''
        },
        { "data": "name" },
        { "data": "position" },
        { "data": "office" },
        { "data": "salary" },
        { "data": "extn", "visible": false }
    ],


HTML:

<thead>
    <tr>
        <th></th>
        <th>Name</th>
        <th>Position</th>
        <th>Office</th>
        <th>Salary</th>
        <th>Extn.</th>
    </tr>
</thead>
