Datatable下拉框

$(document).ready(function() { 
    var table = $('#table_id').DataTable(); 


    $("#table_id tfoot th").each(function (i) { 
     var select = $('<select><option value="clinic number"></option></select>') 
      .appendTo($(this).empty()) 
      .on('change', function() { 
       table.column(0) 
        .search($(this).val()) 
        .draw(); 
      }); 
     table.column(0).data().unique().sort().each(function (d, j) { 
      select.append('<option value="'+d+'">'+d+ "-" +getClinicName(d)+'</option>') 
     }); 
    }); 

});

這是我的下拉框的javascript代碼，但它出現在表內，有沒有什麼辦法可以讓它出現在搜索框旁邊？Datatable下拉框

，你可以做這樣的：

$(document).ready(function() { 
 
     var getClinicName = function(id) { 
 
     return "the name of " + id; 
 
     }; 
 
     $('#example').DataTable({ 
 
     initComplete: function() { 
 
      var select = $('<select><option value=""></option></select>'), 
 
      table = this; 
 
      select.on("change", function() { 
 
      table.api().column(0).search($(this).val()).draw(); 
 
      }); 
 
      $("#example").closest(".dataTables_wrapper").find(".dataTables_filter").append(select); 
 

 
      table.api().columns(0).data().eq(0).unique().sort().each(function(d, j) { 
 
      select.append('<option value="' + d + '">' + d + " - " + getClinicName(d) + '</option>'); 
 
      }); 
 
     } 
 
     }); 
 
    });

這不是我的元素獨特的，也不搜索？ – jasmine825

即使您的代碼段不會過濾，是否有解決此問題的方法？ – jasmine825

問題是如何在搜索框旁邊進行過濾。代碼中的過濾器沒問題，我會將它添加到我的代碼中:) – Veas

您必須將您的選擇附加到#table_id_filter（在您鏈接的HTML中）。

您當前的上下文是「#table_id tfoot th」。事實上，這是在桌子裏面。
