【中文标题】无法按 DataTable 中的列显示过滤器【英文标题】:unable to display the filter by columns in DataTable 【发布时间】:2021-10-27 21:32:23 【问题描述】:

我正在使用数据表,它需要具有基于单个列的搜索功能以及全局搜索 我正在使用二维数组。

它确实放置了搜索框,但它没有进行正确的搜索而不是进行良好的全局搜索

我试过了

                        this.api().columns().every(function() 
                            var that = this;
                            $('input', this.footer()).on('keyup change clear', function() 
                                if (that.search() !== this.value) 
                                    that
                                        .search(this.value)
                                        .draw();
                                
                            );
                        );
                    
                );
            );
        );
    </script>

我需要像这样实现,但是搜索框需要在顶部

【参考方案1】:

我从你的出发点做了一些修改。最终结果:

var dataHere = [
  ["Name", "Role", "Place", "Extn.", "Date"],
  [
    "Tiger Nixon",
    "System Architect",
    "Edinburgh",
    "5421",
    "2011/04/25",
  ],
  [
    "Garrett Winters",
    "Director",
    "London",
    "8422",
    "2011/07/25",
  ]
];
 
$(document).ready(function() 

  // build 2 headers - the 1st for sorting, the 2nd for filtering:
  var head1 = '<tr>';
  var head2 = '<tr>';
  for (var j = 0; j < dataHere[0].length; j++) 
    head1 = head1 + '<th>' + dataHere[0][j] + '</th>';
    head2 = head2 + '<th><input type="' 
        + dataHere[0][j] 
        + '" placeholder="Search ' 
        + dataHere[0][j] + '" /></th>';
  
  head1 = head1 + '</tr>';
  head2 = head2 + '</tr>';
  $("#example thead").html(head1 + head2);
  
  var table = $('#example').DataTable(
    data: dataHere.slice(1),
    orderCellsTop: true,
    initComplete: function() 
      // add event handlers to each of our column filters:
      $('#example thead tr:eq(1) th').each( function (i) 
        $( 'input', this ).on( 'keyup change', function () 
          if ( table.column(i).search() !== this.value ) 
            table.column(i).search( this.value ).draw();
          
         );
       );
    
  );

 );

        <thead></thead>
        <tbody></tbody>
    </table>

</div>

</body>
</html>

我所做的主要更改:

    确保dataHere 行数据在值数量和数据类型方面与标题数据匹配。

    为方便起见,提供带有空 &lt;thead&gt;&lt;tbody&gt; 标记的起始 HTML 结构(使 JavaScript 代码更容易一些)。

    在 JavaScript 中,构建 2 个标题行。这是为了确保排序事件与过滤事件完全分开。否则,如果 DataTable 中只有一个标题行,则每次尝试过滤时都会排序。

    在 DataTable 定义中包含 orderCellsTop: true。从第 (3) 点开始,这告诉 DataTables 只有表中的第一个标题行用于排序。

    删除了不需要的代码。因为您正在预先构建 HTML 表,所以您已经有了所需的过滤器 - 您无需在 DataTable 初始化代码中重复该逻辑。

【参考方案2】:

这行得通。

$(document).ready(function() 
  // Setup - add a text input to each footer cell
  $('#example tfoot th').each(function() 
    var title = $('#example thead th').eq($(this).index()).text();
    $(this).html('<input type="text" placeholder="Search ' + title + '" />');
  );

  // DataTable
  var table = $('#example').DataTable();

  // Apply the search
  table.columns().eq(0).each(function(colIdx) 
    $('input', table.column(colIdx).footer()).on('keyup change', function() 
      table.column(colIdx)
        .search(this.value)
        .draw();
    );
  );
);
