我正在尝试在数据表外部获取具有multiselect的列过滤器。任何帮助将不胜感激。 jsfiddle https://jsfiddle.net/veymt0hj/1/,在页脚中出现了列过滤器中的单选(需要多选)(**需要将其放在外部数据表的顶部)
<table id="example" class="display" style="width:100%">
<thead>
<tr>
<th>Name</th>
<th>Position</th>
</tr>
</thead>
<tbody>
<tr>
<td>Tiger Nixon</td>
<td>System Architect</td>
</tr>
<tr>
<td>Shad Decker</td>
<td>Regional Director</td>
</tr>
<tr>
<td>Michael Bruce</td>
<td>Javascript Developer</td>
</tr>
<tr>
<td>Donna Snider</td>
<td>Customer Support</td>
</tr>
</tbody>
<tfoot>
<tr>
<th>Name</th>
<th>Position</th>
</tr>
</tfoot>
</table>
$(document).ready(function() {
$('#example').DataTable( {
initComplete: function () {
this.api().columns().every( function () {
var column = this;
var select = $('<select><option value=""></option></select>')
.appendTo( $(column.footer()).empty() )
.on( 'change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column
.search( val ? '^'+val+'$' : '', true, false )
.draw();
} );
column.data().unique().sort().each( function ( d, j ) {
select.append( '<option value="'+d+'">'+d+'</option>' )
} );
} );
}
} );
});
