選択した列の列フィルタリング

Question

私のプロジェクトでは、jQuery DataTablesを使用しています。 Idは列のちょうど1（または2）をソートするのが好きです。各列フッターにselectメニューを追加するデータテーブルの例があります。私は非常に限られたJavaScriptスキルを使用してテーブルの上のdivにドロップダウンを移動することができましたが、選択されたいくつかの列だけのメニューを表示する方法が失われました。つまり、position列名前と位置があります）。私のコード（CODEPEN）：

Javascriptを：

$(document).ready(function() { 
    $('#example').DataTable({ 
     initComplete: function() { 
      this.api().columns().every(function() { 
       var column = this; 
       var select = $('<select><option value=""></option></select>') 
        .appendTo($("#sort")) 
        .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>') 
       }); 
      }); 
     } 
    }); 
}); 

Answer 1

変更

this.api().columns().every(function() { 

0と 1はあなたが対象となるゼロベースの列索引です

this.api().columns([0, 1]).every(function() { 

へフィルタが表示されます。

コードとデモンストレーションについては、updated codepenを参照してください。

Answer 2

編集：このケースでは、ジャイロコードがより良い答えを持っていると思います。

位置以外のすべての列のドロップをスキップするだけの場合は、スナップされたようなものを試すことができます。 cfa1とマークされた行を探します。

$(document).ready(function() { 
 
    $('#example').DataTable({ 
 
    initComplete: function() { 
 
     this.api().columns().every(function() { 
 
     if ($(this.header()).html() != "Position") /* cfa1 */ 
 
      return; /* cfa1 */ 
 
     var column = this; 
 
     var select = $('<select><option value=""></option></select>') 
 
      .appendTo($("#sort")) 
 
      .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>') 
 
     }); 
 
     }); 
 
    } 
 
    }); 
 
});
